Peri and the Piscon Paradox (audio story)

Synopsis
''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.''

Cast

 * Peri Brown - Nicola Bryant
 * Sixth Doctor - Colin Baker

Story notes

 * 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, including one who is actually killed in DW: Mindwarp, one who marries Yrconos and becomes a warrior queen (DW: The Ultimate Foe and NA: Bad Therapy), and the version who narrates Part 2 who only remembers the events of DW: Planet of Fire. The nature of the other two versions is not revealed.
 * It also includes several meetings between the Fifth and Sixth Doctors, though the Fifth Doctor is unaware of his future self's identity.
 * Disc 1 tells the story from the Fifth Doctor and the younger Peri's viewpoint; disc 2 re-explores the story from the Sixth Doctor & 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 Bryant joined the series, and Part 2 uses the Dominic Glynn "Trial" theme used at the time she left.
