Doctor Who: The First 100 Big Finish Monthly Adventures, Releases 101–200
A complete retrospective, story guide, cast breakdown and exploration of the range’s second century
Executive summary
Big Finish Productions’ Doctor Who: The Monthly Adventures entered its second century in October 2007 with Absolution, the concluding chapter of an important period in the Eighth Doctor’s audio adventures. By release 200, The Secret History, published in 2015, the range had travelled through historical mysteries, political thrillers, psychological horror, comic adventures and ambitious stories involving some of the programme’s most familiar enemies.
The first hundred releases established the format. The next hundred expanded its possibilities.
During this period, Big Finish continued to give Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann opportunities to develop their Doctors beyond their original television appearances. Their adventures became increasingly diverse, with returning companions sharing the spotlight with newly created characters and guest performers.
The Fifth Doctor’s stories revisited the world of Nyssa, Peri and Erimem before welcoming new characters such as Thomas Brewster into his adventures. The Sixth Doctor’s continuing partnership with Evelyn Smythe remained an important part of the range, while his stories with Charley Pollard created a new dynamic. The Seventh Doctor’s adventures with Ace and Hex explored the consequences of the Doctor’s manipulative tendencies. Meanwhile, the Eighth Doctor’s later appearances in the Monthly Adventures connected his earlier Charley and C’rizz stories with a wider collection of adventures featuring other companions.
Several developments stand out. The Girl Who Never Was brought the original Charley Pollard storyline to a major conclusion. The Haunting of Thomas Brewster began a trilogy that would give the Fifth Doctor a new companion. The Key 2 Time trilogy created a substantial story arc for the Seventh Doctor, while The Company of Friends brought together four different perspectives on the Eighth Doctor’s life. The ambitious A Death in the Family became a particularly significant chapter in the Seventh Doctor’s relationship with Ace and Hex.
Later releases explored alternative histories, wartime societies, the legacy of the Cybermen and the psychological consequences of the Doctor’s actions. By the time the range reached its 200th release, Big Finish had established a substantial fictional universe whose character development and continuity extended far beyond individual adventures.
This article follows the numbered releases from 101, Absolution, to 200, The Secret History. It provides a release-by-release guide, an overview of the leading cast and companions, and an assessment of the range’s creative development.
Editorial note: The story summaries below are original, spoiler-conscious overviews. Where a release contains multiple adventures, the discussion identifies the anthology or linked-story format. Cast references concentrate on the principal performers and recurring characters rather than attempting to list every guest actor in every production.
1. Entering the second century: Releases 101–113
The second hundred begins with several stories that continue the range’s established character arcs while introducing new settings, enemies and narrative possibilities. The official Big Finish catalogue identifies Absolution as release 101, The Mind’s Eye as 102 and The Girl Who Never Was as 103. (Big Finish; Big Finish)
101. Absolution
Doctor: Eighth
Companions: Charley Pollard and C’rizz
Principal cast: Paul McGann, India Fisher and Conrad Westmaas
Absolution continues the Eighth Doctor’s complicated journey with Charley and C’rizz. Their travels have become increasingly shaped by questions of trust, responsibility and the consequences of earlier decisions. The adventure brings that period of the Doctor’s life towards a major turning point, making it an important entry in the continuing narrative rather than simply another standalone visit to an alien world.
102. The Mind’s Eye
Doctor: Fifth
Companions: Peri Brown and Erimem
Principal cast: Peter Davison, Nicola Bryant and Caroline Morris
This release contains Colin Brake’s three-part story The Mind’s Eye and Nicholas Briggs’s shorter adventure Mission of the Viyrans. The principal story explores a mysterious planet, the Doctor’s unreliable memories and dangerous plant life, while Erimem’s storyline connects the adventure to political developments elsewhere. The companion piece introduces the Viyrans, an organisation of time-travelling alien medics whose activities would later become important in Big Finish’s wider Doctor Who catalogue. (Big Finish)
103. The Girl Who Never Was
Doctor: Eighth
Companion: Charley Pollard
Principal cast: Paul McGann and India Fisher
A ghost ship, a girl whose memory is missing and a journey to Singapore in 1931 combine in a story centred on Charley’s fate. It is a significant entry in the Eighth Doctor’s original monthly run, bringing her long relationship with the Doctor to a dramatic turning point.
The story also demonstrates how Big Finish could make a companion’s personal history the central mystery, rather than treating her merely as a witness to the Doctor’s adventures. (Big Finish)
104. The Bride of Peladon
Doctor: Fifth
Companions: Peri Brown and Erimem
Principal cast: Peter Davison, Nicola Bryant and Caroline Morris
The Doctor returns to Peladon, a world familiar to television viewers from the Third Doctor era. A missing girl, a murdered queen and a mysterious voice plunge the royal household into intrigue. The familiar setting gives the adventure a strong connection to the programme’s past, while Peri and Erimem bring contrasting perspectives to its political mystery. (Big Finish)
105. The Condemned
Doctor: Sixth
Companion: Charlotte Pollard
Principal cast: Colin Baker and India Fisher
The Sixth Doctor lands in a modern tower block in Manchester, where a murder makes him a suspect. Detective Inspector Patricia Menzies investigates the case while a young woman named Maxine becomes involved in a conspiracy with much wider implications.
The story is notable for bringing Charley into the Sixth Doctor’s adventures. Her familiar relationship with the Eighth Doctor gives way to a very different partnership, revealing how differently the same companion can interact with another incarnation. (Big Finish)
106. The Dark Husband
Doctor: Seventh
Companions: Ace and Hex
Principal cast: Sylvester McCoy, Sophie Aldred and Philip Olivier
The Seventh Doctor, Ace and Hex enter a story shaped by unsettling events and complicated relationships. Its darker atmosphere suits the Doctor’s increasingly ambiguous methods, while Hex’s presence continues to alter the emotional balance of the TARDIS team.
107. The Haunting of Thomas Brewster
Doctor: Fifth
Companion: Nyssa
Principal cast: Peter Davison, Sarah Sutton and John Pickard
Thomas Brewster’s life is haunted by mysterious appearances and temporal complications. The Doctor’s investigation leads into a web of events involving Victorian London, strange apparitions and the TARDIS’s relationship with Brewster.
This is the beginning of a significant trilogy. Brewster becomes a recurring figure in the Fifth Doctor’s audio adventures, giving the range a new companion whose history is tied to the consequences of time travel. (Big Finish)
108. Assassin in the Limelight
Doctor: Sixth
Companion: Evelyn Smythe
Principal cast: Colin Baker and Maggie Stables
The Doctor and Evelyn investigate a historical mystery involving the world of medicine and the ambitions of people seeking recognition. Evelyn’s scholarly background gives her a natural role in a story where evidence, reputation and ethical responsibility matter as much as the immediate danger.
109. The Death Collectors
Doctor: Seventh
Principal cast: Sylvester McCoy and a guest ensemble
A mysterious force gathers the dead, drawing the Seventh Doctor into a disturbing investigation. The story uses its unusual premise to explore the boundary between life and death and the Doctor’s determination to uncover the truth behind events that seem beyond ordinary explanation.
110. The Boy That Time Forgot
Doctor: Fifth
Companion: Nyssa
Principal cast: Peter Davison and Sarah Sutton
The Doctor and Nyssa are transported from Victorian London to a prehistoric world. Joined by adventurers Rupert Von Thal and Beatrice Mapp, they encounter a lost civilisation and a mysterious figure whose relationship with time is central to the adventure. (Big Finish)
111. The Doomwood Curse
Doctor: Sixth
Companion: Charley Pollard
Principal cast: Colin Baker and India Fisher
The Doctor and Charley encounter a mystery built around an ominous location and the possibility that the supernatural may be hiding something more dangerous. Their partnership continues to develop as Charley adapts to the Sixth Doctor’s more forceful personality.
112. Kingdom of Silver
Doctor: Seventh
Principal threat: Cybermen
Principal cast: Sylvester McCoy and a guest ensemble
The Cybermen return in a story involving a society shaped by technology and the pursuit of power. The Doctor must investigate the threat while confronting the familiar question at the heart of the Cybermen: what happens when survival is valued above individuality?
113. Time Reef
Doctor: Fifth
Companion: Nyssa
Principal cast: Peter Davison and Sarah Sutton
The Fifth Doctor and Nyssa encounter a mystery involving time and the consequences of travelling through it. The story continues the era’s interest in strange environments and temporal complications, while keeping the Doctor’s concern for individuals at its centre.
What this opening group achieves: Releases 101–113 show the range balancing endings and beginnings. Charley’s original journey reaches a major turning point, while Thomas Brewster’s arrival establishes a new continuing story for the Fifth Doctor. Familiar enemies remain important, but the strongest stories often begin with a personal mystery.
2. New directions and the return of familiar enemies: Releases 114–126
The next group moves between stories featuring established companions, new narrative arcs and more experimental formats. The range’s identity is now firmly established, allowing its writers to vary the tone without losing the central character relationships.
114. Brotherhood of the Daleks
Doctor: Eighth
Companion: Charley Pollard
Principal threat: Daleks
The Daleks return in a story that connects their familiar desire for supremacy with questions of identity and belonging. The Eighth Doctor must investigate the organisation and motivations behind the threat, while Charley is drawn into a conflict that tests her judgement.
115. Forty-Five
Doctor: Seventh
Companions: Ace and Hex
An anthology of four linked stories, Forty-Five uses its title as a unifying idea while allowing different writers to explore the Seventh Doctor’s world from different angles. Its structure is one of the range’s strengths: it can deliver several self-contained dramatic experiences within one release while maintaining a shared atmosphere.
116. The Raincloud Man
Doctor: Sixth
Companion: Charley Pollard
A strange phenomenon becomes the starting point for an adventure that combines mystery with a more character-focused story. The Doctor and Charley must work out what lies behind events that initially appear impossible to explain.
117. The Key 2 Time: The Judgement of Isskar
Doctor: Seventh
Companion: Ace
The first part of a trilogy based around the Key to Time mythology, this adventure sends the Doctor and Ace into a story involving ancient history, competing powers and a larger cosmic objective. It establishes the structure for the two releases that follow.
118. The Key 2 Time: The Destroyer of Delights
Doctor: Seventh
Companion: Ace
The trilogy continues as the Doctor and Ace investigate the consequences of their search. The story develops the larger mythology while placing the characters in situations that challenge their assumptions about the forces involved.
119. The Key 2 Time: The Chaos Pool
Doctor: Seventh
Companion: Ace
The concluding chapter brings the trilogy’s central mystery to a head. Rather than functioning as an isolated adventure, it depends on the accumulated revelations and choices of the preceding stories.
120. The Magic Mousetrap
Doctor: Sixth
Companion: Charley Pollard
A seemingly whimsical premise leads the Doctor and Charley into a more unsettling mystery. The story illustrates the range’s ability to begin with a playful idea and gradually reveal its darker implications.
121. Enemy of the Daleks
Doctor: Seventh
Principal threat: Daleks
The Seventh Doctor confronts another Dalek crisis, but the story’s focus is not simply on their destructive capabilities. The central mystery asks what happens when the Daleks’ own assumptions and internal priorities become part of the conflict.
122. The Angel of Scutari
Doctor: Fifth
Companion: Peri Brown
Set against the historical world of medical care and military conflict, this story brings the Doctor and Peri into a situation where compassion and the realities of war come into sharp focus. It uses history to explore the tension between saving individual lives and confronting wider systems of suffering.
123. The Company of Friends
Doctor: Eighth
Featured companions: Mary Shelley, Charley Pollard, Lucie Miller and Benny Summerfield
This anthology is a particularly important release in the Eighth Doctor’s history. Four separate stories connect the Doctor with companions from different periods of his life, including the literary figure Mary Shelley and the audio-original companion Lucie Miller.
Its format allows each relationship to have its own tone and historical setting. The result is a portrait of the Eighth Doctor as a traveller whose life is defined not by one continuous companion era but by a series of distinct friendships.
124. Patient Zero
Doctor: Sixth
Companion: Charley Pollard
The Doctor and Charley become involved in a mystery involving disease, scientific investigation and a threat with wider consequences. Their relationship remains central, as the story asks how far the Doctor can go to understand a crisis without putting others at risk.
125. Paper Cuts
Doctor: Seventh
Companions: Ace and Hex
A story involving documents, records and the written word turns apparently ordinary objects into clues. The adventure uses the Doctor’s investigative instincts while continuing the character development of Ace and Hex.
126. Blue Forgotten Planet
Doctor: Eighth
Companions: Charley Pollard and C’rizz
This release brings a major phase of the Eighth Doctor’s original monthly narrative to a close. The story explores the consequences of the Doctor’s relationship with Charley and C’rizz, bringing their shared journey towards a significant ending.
What this group achieves: The range increasingly uses long-form storytelling alongside anthology experiments. The Key 2 Time demonstrates the potential of a connected trilogy, while The Company of Friends shows how an anthology can expand a Doctor’s character through separate companion relationships.
3. The Fifth and Seventh Doctors in a changing range: Releases 127–139
The stories that follow explore different forms of adventure, from haunted houses and historical mysteries to psychological drama. They also demonstrate how returning companions can be used in fresh ways rather than simply recreating their television-era roles.
127. Castle of Fear
Doctor: Fifth
Companion: Nyssa
The Doctor and Nyssa investigate a mystery in a seemingly threatening castle. The story uses the familiar gothic setting to explore hidden motives and the possibility that the apparent supernatural threat conceals a more complicated reality.
128. The Eternal Summer
Doctor: Fifth
Companion: Nyssa
A world trapped in a seemingly endless season becomes the setting for a mystery about time, memory and change. The Doctor and Nyssa must uncover why the environment behaves so strangely and what its inhabitants have lost in the process.
129. Plague of the Daleks
Doctor: Fifth
Companion: Peri Brown
Principal threat: Daleks
The Daleks return in an adventure built around a spreading crisis. The Doctor and Peri must investigate the cause and prevent the threat from becoming uncontrollable, while the story explores the familiar Dalek themes of domination and survival.
130. A Thousand Tiny Wings
Doctor: Seventh
Companion: Elizabeth Klein
Elizabeth Klein, a scientist whose history is complicated by an altered timeline, becomes central to a story about identity, memory and historical change. Her relationship with the Seventh Doctor is unusual because she is not simply a companion who has joined him on an ordinary journey: her own history is bound up with the Doctor’s decisions.
131. Survival of the Fittest
Doctor: Seventh
Companion: Elizabeth Klein
The story continues the Doctor and Klein’s complicated partnership. It explores the implications of her beliefs and the difficulty of changing someone’s worldview when that worldview has been shaped by a different version of history.

Companion: Elizabeth Klein
The Klein trilogy reaches its conclusion. The Doctor confronts the larger consequences of the alternate history that has shaped Klein’s life, bringing her story to a major turning point.
133. City of Spires

134. The Wreck of the Titan
Doctor: Sixth
Companion: Jamie McCrimmon
The Doctor and Jamie encounter a mystery associated with a damaged vessel and the events surrounding it. The setting provides opportunities for suspense and character-based investigation.
135. Legend of the Cybermen
Doctor: Second
Companions: Jamie McCrimmon and Zoe Heriot
Principal threat: Cybermen
This release is a significant departure from the range’s usual Doctor rotation, featuring the Second Doctor through the return of his television-era companions. It revisits the Cybermen and the mythology associated with them, while giving Jamie and Zoe an opportunity to return to the Doctor’s world.
136. Cobwebs
Doctor: Fifth
Companions: Nyssa, Tegan and Turlough
The Fifth Doctor is reunited with companions from his television era. Their return gives the story an emotional dimension that depends on the audience’s familiarity with the characters and their shared history.
137. The Whispering Forest
Doctor: Fifth
Companions: Nyssa, Tegan and Turlough
The TARDIS team investigate an unsettling environment where the forest itself seems to be connected to the danger. The story continues the returning-companion sequence and builds on the relationships established in Cobwebs.
138. The Cradle of the Snake
Doctor: Fifth
Companions: Nyssa, Tegan and Turlough
The trilogy reaches its conclusion with a story that draws together its central mystery and the relationships between the returning companions. It is an example of Big Finish using a television-era TARDIS team for a longer narrative rather than a single reunion special.
139. Project: Destiny
Doctor: Seventh
Companions: Ace and Hex
The Doctor, Ace and Hex encounter a mystery with consequences that extend beyond a single adventure. The story continues the range’s interest in the Seventh Doctor’s tendency to conceal information, make plans and accept risks that his companions may not fully understand.
What this group achieves: These releases illustrate the value of continuity. Elizabeth Klein’s trilogy, the Fifth Doctor reunion stories and the return of the Second Doctor demonstrate how Big Finish can explore the long-term consequences of characters’ histories while keeping the stories accessible as adventures in their own right.
4. Emotional consequences and ambitious storytelling: Releases 140–151
This period includes several major developments for the Seventh Doctor, a new chapter in the Thomas Brewster storyline and a series of adventures that examine the Doctor’s responsibility for the people he encounters.
140. A Death in the Family
Doctor: Seventh
Companions: Ace and Hex

Its emotional consequences extend beyond the immediate plot, making it an important reference point for later stories featuring Ace and Hex.
141. Lurkers at Sunlight’s Edge
Doctor: Seventh
Companions: Ace and Hex
A mystery involving an isolated environment and an unseen threat places the TARDIS team in a situation where observation and interpretation become essential. The story uses the Doctor’s investigative skills while allowing the companions to respond to the danger in their own ways.
142. The Demons of Red Lodge and Other Stories
Doctor: Fifth
Companion: Nyssa
An anthology of shorter stories gives the Fifth Doctor and Nyssa a collection of distinct adventures. The format allows the range to move between different tones and settings without needing to build a single long narrative across the entire release.
143. The Crimes of Thomas Brewster
Doctor: Fifth
Companion: Nyssa

144. The Feast of Axos
Doctor: Third
Companions: Jo Grant and UNIT
The Third Doctor returns in a story that draws on the UNIT era of television and the legacy of Axos. It is another example of the Monthly Adventures widening their range of Doctors beyond the original Fifth-to-Eighth rotation.

150. Recorded Time and Other Stories
Doctor: Fifth
Companion: Nyssa
This anthology uses several shorter stories to explore the Fifth Doctor and Nyssa’s travels from different angles. The release demonstrates how the range’s established characters can sustain both conventional adventures and more compact experiments in storytelling.
151. The Doomsday Quatrain
Doctor: Seventh
Companions: Ace and Hex
A prophecy and the threat of impending catastrophe become the foundation for an adventure in which the Doctor must distinguish genuine warning from manipulation. The story uses the Seventh Doctor’s interest in long-term plans while examining the dangers of assuming that the future is already settled.
What this group achieves: The range becomes increasingly comfortable with emotional consequences and complex character relationships. The stories involving Ace, Hex, Brewster and Flip show how the Doctor’s companions can alter the nature of the adventures around them, rather than simply providing an audience for the Doctor’s discoveries.
5. Historical mysteries and the return of classic monsters: Releases 152–163
The next group demonstrates the breadth of the range’s storytelling. Historical settings, psychological drama, military science fiction and familiar monsters all feature, with the four Doctors continuing to develop distinct styles.

157. The Fourth Wall
Doctor: Sixth
Companion: Flip Jackson
The Doctor and Flip investigate a mystery that plays with the boundaries between perception and reality. The story’s title suggests its interest in the way audiences interpret what they hear and the way characters understand the worlds they inhabit.
158. Wirrn Isle
Doctor: Fifth
Companion: Nyssa
The Wirrn return in an adventure involving a dangerous environment and a threat capable of spreading beyond its original setting. The Doctor and Nyssa must understand the creatures’ behaviour and prevent the situation from becoming uncontrollable.

163. Black and White
Doctor: Seventh
Companions: Ace and Hex
This story begins a larger narrative that explores division, identity and the consequences of choices. Its themes connect naturally with the Seventh Doctor’s tendency to think several steps ahead, while the companions must decide how much they can trust his plans.
What this group achieves: The range continues to combine familiar monsters with new historical and psychological stories. Davros, the Wirrn and the Cybermen belong to the programme’s established mythology, but their return is balanced by adventures whose central mysteries are built around people, places and ideas.
6. The range grows more experimental: Releases 164–175
This period includes some of the Monthly Adventures’ most distinctive ideas, from mythological settings and political intrigue to stories that directly examine the Doctor’s relationships and the consequences of his interventions.
164. The Magic Mousetrap

165. The Angel of Scutari

166. The Company of Friends
Doctor: Eighth

What this group achieves: These releases illustrate the Monthly Adventures’ ability to shift between anthology storytelling, continuing character arcs and familiar monster adventures. The Klein trilogy is especially important because it uses time travel not merely as a plot device but as the foundation of a character’s worldview.
7. New companions, old enemies and shifting perspectives: Releases 176–188

183. A Death in the Family
Doctor: Seventh
Companions: Ace and Hex
A major story for the Seventh Doctor, A Death in the Family places personal relationships and emotional consequences at the centre of the adventure.

8. The road towards release 200: Releases 189–200
The final twelve releases in this retrospective bring together military science fiction, mystery, character drama and stories that revisit the programme’s classic monsters. They culminate in The Secret History, a Fifth Doctor adventure that draws on the mythology of the Time Lords.

Doctor: Sixth
Companion: Evelyn Smythe
Principal character: Davros
Davros returns in an adventure that explores the legacy of his experiments and the destructive consequences of his ambition. Evelyn’s moral perspective gives the confrontation an additional dimension, encouraging the Doctor to consider not only how to defeat Davros but what his choices reveal about the nature of scientific responsibility.
200. The Secret History
Doctor: Fifth
Companions: Nyssa, Steven Taylor and Vicki
The bicentenary of the range’s numbered releases is marked by a story that draws on the history and mythology of the Time Lords. The Fifth Doctor encounters characters whose connections to the programme’s early years give the adventure a strong sense of historical continuity.
The presence of Steven Taylor and Vicki links the story to the First Doctor’s era, while the Fifth Doctor’s perspective allows the narrative to explore the consequences of knowledge hidden within the history of Gallifrey.
As a milestone release, The Secret History is well suited to the range’s broader purpose: revisiting the past while creating new stories that add to the Doctor’s continuing life.
What this final group achieves: The range arrives at release 200 with a broad selection of storytelling styles and a well-established fictional history. The final stretch brings together returning monsters, original companions, historical settings and the mythology of the Time Lords, demonstrating how much the Monthly Adventures had expanded since their beginning.
9. Cast breakdown: The four principal Doctors
The first hundred releases of the second century continue to revolve around Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann. Their returning performances provide the foundation on which the range’s changing cast and stories are built.
The Fifth Doctor — Peter Davison
The Fifth Doctor’s adventures often emphasise empathy, decency and the difficulty of doing the right thing when history or circumstances offer no easy solution. His stories with Nyssa, Peri and Erimem revisit familiar television relationships, while Thomas Brewster introduces a more complicated companion dynamic.
Davison’s performances are particularly effective when the Doctor is placed in situations where compassion conflicts with the practical demands of survival. The Thomas Brewster trilogy, the returning-companion stories and The Secret History all illustrate different aspects of this incarnation.
The Sixth Doctor — Colin Baker
The Sixth Doctor’s boldness and confidence give his adventures a distinctive energy. His audio stories often allow his compassion to emerge through disagreement, argument and his determination to challenge unjust authority.
His relationships with Evelyn Smythe, Charley Pollard and Flip Jackson demonstrate the range of dynamics available to the character. Evelyn provides an intellectual equal, Charley brings experience from her travels with the Eighth Doctor, and Flip introduces a different contemporary perspective.
The Seventh Doctor — Sylvester McCoy
The Seventh Doctor remains the range’s most strategic and secretive incarnation. His adventures frequently involve hidden agendas, historical manipulation and enemies who must be outthought rather than simply defeated.
Ace and Hex are essential to this portrayal. They are not merely passengers on the TARDIS: their relationships with the Doctor develop through the consequences of his decisions, particularly when he withholds information or asks them to accept risks they do not fully understand.
Elizabeth Klein’s trilogy also demonstrates the Seventh Doctor’s complicated relationship with history. Her alternate timeline provides a way to examine how the Doctor’s actions can change an individual’s identity and worldview.
The Eighth Doctor — Paul McGann
The Eighth Doctor’s later monthly adventures connect his original journey with Charley and C’rizz to a wider range of historical and character-focused stories. His appearances with Mary Shelley and other companions show how the incarnation can change depending on the person travelling beside him.
McGann’s performance balances warmth, enthusiasm and melancholy. The character’s optimism is often tested by the consequences of his decisions, giving his adventures a continuing emotional dimension.
10. The companions: The people who shape the Doctor’s adventures
Nyssa — Sarah Sutton
Nyssa remains one of the Fifth Doctor’s most consistent companions during this period. Her scientific intelligence and thoughtful approach make her a natural partner for investigations involving biology, technology and unfamiliar civilisations.
Her return alongside Tegan and Turlough also allows the range to revisit the dynamics of the original television team while giving the characters new experiences.
Peri Brown — Nicola Bryant
Peri’s relationship with the Fifth and Sixth Doctors offers two contrasting versions of the companion dynamic. With the Fifth Doctor, she is part of a team that includes Erimem; with the Sixth, she is a familiar travelling partner whose history gives their adventures additional emotional context.
Charley Pollard — India Fisher
Charley’s significance extends beyond her original partnership with the Eighth Doctor. Her adventures with the Sixth Doctor show how a companion’s character can be reinterpreted through a different relationship.
Her presence in The Condemned, The Raincloud Man, The Magic Mousetrap and other releases creates a bridge between separate periods of the Monthly Adventures.
Evelyn Smythe — Maggie Stables
Evelyn remains one of Big Finish’s most important original companions. Her intelligence, maturity and willingness to challenge the Doctor make her an equal participant in their adventures.
Her relationship with the Sixth Doctor is built on mutual respect rather than unquestioning admiration. That quality gives the stories an unusual emotional texture and allows difficult ethical questions to emerge naturally through dialogue.
Ace and Hex — Sophie Aldred and Philip Olivier
Ace and Hex form one of the range’s most significant continuing teams. Ace’s determination and experience are balanced by Hex’s more contemporary outlook, while the Doctor’s secrecy creates ongoing tension.
Their stories often ask whether the Doctor’s long-term plans justify the emotional risks he imposes on his companions. This makes the Seventh Doctor’s adventures particularly effective when the immediate threat is connected to a larger personal consequence.
Elizabeth Klein — Tracey Childs
Klein’s relationship with the Seventh Doctor is unusual because her history is bound up with an alternative timeline. Her beliefs and decisions are shaped by experiences that the Doctor understands but cannot simply erase.
The trilogy formed by A Thousand Tiny Wings, Survival of the Fittest and The Architects of History gives her a substantial story arc centred on identity and historical change.
Thomas Brewster — John Pickard
Brewster becomes a recurring figure in the Fifth Doctor’s adventures, bringing a complicated personal history and an unusual relationship with time travel. His trilogy demonstrates how a companion’s actions can create problems that cannot be solved in a single adventure.
Mary Shelley — Julie Cox
Mary Shelley brings a literary and historical dimension to the Eighth Doctor’s adventures. Her perspective creates opportunities to explore nineteenth-century ideas about science, invention and the nature of life.
Her stories also give the Eighth Doctor a different kind of companion relationship, shaped by intellectual curiosity and the historical context in which she lives.
Flip Jackson — Lisa Greenwood
Flip’s adventures with the Sixth Doctor introduce a new contemporary companion dynamic. Her stories range from military science fiction to personal mysteries, giving the Doctor a partner whose perspective differs from both Evelyn’s academic approach and Charley’s experience as a time traveller.
11. The recurring villains and the wider mythology
The Daleks
The Daleks remain one of the range’s most frequently revisited enemies. Their appearances continue to explore the dangers of absolute ideology, the desire for supremacy and the destructive consequences of treating other forms of life as inferior.
Stories involving the Daleks are most effective when they do more than stage a confrontation. They can reveal how societies adapt to fear, how enemies justify their own actions and how the Doctor’s moral principles are tested by the prospect of overwhelming force.
The Cybermen
The Cybermen continue to embody the conflict between survival and individuality. Their return in stories such as Kingdom of Silver and Legend of the Cybermen allows the range to revisit familiar ideas while exploring new settings and circumstances.
Davros
Davros remains an especially useful antagonist because his intelligence is inseparable from his ambition. His stories frequently ask whether scientific achievement can be separated from the moral responsibilities of the person who creates it.
The Master and the Time Lords
The Time Lords’ history provides a source of political and philosophical conflict throughout the range. The Doctor’s relationship with his own civilisation is often complicated by secrets, competing interpretations of history and the consequences of past decisions.
New threats and original characters
The range’s original adversaries are equally important. Strange societies, unexplained phenomena, dangerous technologies and historical conspiracies allow writers to explore themes that are not tied to a particular monster.
This variety prevents the Monthly Adventures from becoming dependent on nostalgia. The returning villains provide familiarity, while original threats create space for experimentation.
12. The writers and the evolution of audio storytelling
The second hundred releases reflect a widening range of creative approaches. Established Big Finish writers continued to develop the Doctors and companions, while newer contributors brought different styles and interests to the monthly format.
The anthology releases demonstrate how the range could accommodate multiple writers within one production. Forty-Five, The Company of Friends, The Demons of Red Lodge and Other Stories and Recorded Time and Other Stories all allow different kinds of stories to coexist under one release number.
The longer arcs show a different strength. The Key to Time trilogy, the Elizabeth Klein trilogy and the Thomas Brewster stories use the continuing format to create developments that would be difficult to achieve through unrelated standalone adventures.
This balance between experimentation and continuity is one of the range’s defining achievements. A listener can enjoy a single mystery, follow a companion’s entire journey or explore a larger narrative spanning several releases.
13. The importance of the second hundred
The first hundred releases established the Monthly Adventures as a continuing home for classic Doctors and companions. The second hundred demonstrates what happens when that format becomes mature.
Character development becomes more ambitious. Companions such as Klein, Brewster and Flip have their own histories and consequences that extend beyond one story.
Continuity becomes more flexible. The range can revisit familiar television teams, introduce a companion from another Doctor’s era or tell a story involving the Doctor’s earlier incarnations.
Anthology storytelling becomes a recognised format. Multiple shorter stories can explore one theme or character without requiring a single plot to occupy an entire release.
The Doctor’s moral responsibilities become increasingly important. Many stories are concerned not simply with defeating an enemy but with understanding the damage caused by conflict, technology, ideology and the Doctor’s own decisions.
The audio medium remains central to the storytelling. Dialogue, sound design and atmosphere allow the range to create intimate mysteries and unsettling environments without needing to imitate television visually.
14. How the second century compares with the first
The first hundred releases are often associated with establishing the format, introducing Evelyn and Charley, and giving the Eighth Doctor a sustained audio era. The second hundred builds on that foundation rather than abandoning it.
The Doctors remain recognisable, but their relationships become more complicated. The companions are increasingly important to the long-term narrative. Returning enemies are explored through new contexts, and original characters become part of a larger continuity.
The range also becomes more comfortable with structural experimentation. Anthologies, trilogies, reunions and stories involving alternate histories all sit alongside conventional adventures.
The result is a series that has become more than a collection of new stories featuring familiar actors. It is a continuing fictional world in which events can have consequences, companions can change the Doctor’s life and the programme’s history can be revisited without being simply repeated.
15. Final assessment: A second century of possibilities
The Monthly Adventures’ releases 101–200 show Big Finish at a stage of growing confidence and ambition. The range had already proved that classic Doctors could return to new adventures. Its second century demonstrates how those adventures could support deeper character development, continuing story arcs and more varied narrative structures.
The Eighth Doctor’s journey with Charley and C’rizz reaches important turning points. The Fifth Doctor gains a new recurring figure in Thomas Brewster. The Sixth Doctor’s relationships with Evelyn, Charley and Flip demonstrate the value of different companion dynamics. The Seventh Doctor’s stories with Ace, Hex and Elizabeth Klein explore the consequences of secrecy and long-term planning.
The recurring villains remain central, but the range’s strongest achievements are not limited to monster stories. Historical mysteries, alternate timelines, companion reunions and anthologies all contribute to a wider picture of the Doctor’s life.
By release 200, The Secret History, Big Finish had created a substantial body of work that could stand alongside the programme’s television history while retaining its own identity. The Monthly Adventures had become a place where familiar characters could grow, where new companions could become essential to the Doctor’s story, and where audio drama could explore the emotional and philosophical implications of time travel.
In summary: releases 101–200 represent the Monthly Adventures’ move from a successful continuation of classic Doctor Who into a mature, interconnected audio universe. Their legacy lies in the depth of their character relationships, the variety of their storytelling and the willingness to make the Doctor’s past an active part of his future.
