Peri and the Piscon Paradox was the seventh story of the fifth series of The Companion Chronicles audio range. It was produced by Big Finish Productions. It was written by Nev Fountain and features Peri Brown and the Sixth Doctor.

It was the first Companion Chronicles release to feature an actor who regularly played the Doctor, with Colin Baker playing his role of the Sixth Doctor. However, Nicola Bryant provides narration as well as the Fifth Doctor's dialogue.

Publisher's summary[]

The Doctor and Peri journey to Los Angeles 2009 to do battle with a Piscon. His name is Zarl, and he's a fish of utmost evil.

Zarl is going to steal all the water of Earth and sell it to the highest bidder. Or blow up the San Andreas fault. Or the planet. Or something like that. He's a bit vague on that point.

Fortunately, to stop him there's help from an unexpected source: a future version of Peri. She knows Zarl's dark secret.

But should the future Peri be on Earth at all? Something smells fishy — and it's not just Zarl.

Theories and concepts[]


  • This story explains in more detail what happened to Peri after the Trial of a Time Lord story arc. Specifically, it reveals that there are no less than five versions of Peri Brown in existence, each created by Time Lord interference in her timeline - not including the original, who was killed in Mindwarp. One of the five rescued Peris married Yrcanos and became a warrior queen (TV: The Ultimate Foe, PROSE: Bad Therapy), while another version narrates Part 2 of this story, only remembering the events of TV: Planet of Fire. The nature of the other three versions is not revealed.
    • Another version of Peri who is only married to Yrcanos for seven days and rejoins the Doctor in his travels appears in the audio story The Widow's Assassin, as well as Masters of Earth and The Rani Elite.
    • The Seventh Doctor and Chris Cwej meet a version of Peri who seeks to get away from her marriage after two decades and is able to use a time portal to travel to Earth in the 1990s (PROSE: Bad Therapy), but it is unclear if this Peri would be the same as the Peri who stayed with Yrcanos and had three children or a different Peri.
  • This story features several meetings and even a physical altercation between the Fifth and Sixth Doctors, though the Fifth Doctor remains unaware of his future self's identity.
  • Disc 1 tells the story from the Fifth Doctor and the younger Peri's viewpoint whereas Disc 2 re-explores the story from the Sixth Doctor and the older Peri's view. Although Nicola Bryant performs the voice of the Fifth Doctor, Colin Baker himself performs the Sixth Doctor, becoming the first Doctor actor to appear in a Companion Chronicles release. Also, befitting a story set in two different eras, Part 1 uses the Peter Howell theme arrangement in place at the time that Bryant joined the series during Season 21, and Part 2 uses the Dominic Glynn theme used at the time she left during Season 23.
  • The first and second halves of this story take place at the same time. The same is true of both Flip-Flop and The Veiled Leopard.
  • This audio drama was recorded on 11 and 12 November 2009 at The Moat Studios.
  • Coincidentally, Clara Oswald - who was introduced two years later - also has multiple versions/copies, two of whom (Oswin Oswald and Clara Oswin Oswald) died and many whom encountered the Doctor. (Asylum of the Daleks, The Snowmen)
  • From the Fifth Doctor and the young Peri's perspective, this story is set between Planet of Fire and The Caves of Androzani. From the Sixth Doctor's perspective, it's between The Trial of a Time Lord and Time and the Rani.
  • This story was originally released on CD and download. It is now available as a download only.
