Accused of `crimes against the inviolate laws of evolution’, the Sixth Doctor is on trial for his life.

The sinister prosecutor, the Valeyard, presents the High Council of Time Lords with the second piece of evidence against The Doctor: a dramatic adventure on the planet Thoros Beta which led to the renegade Time Lord’ summons to the Court of Enquiry.

But as The Doctor watches the scenes on the Matrix he is puzzled by what he sees – his behaviour is not as he remembers. Only one thing is certain: on the evidence of the Matrix The Doctor is surely guilty as charged …

  • Martin adds a tongue-in-cheek epilogue that reveals that Peri had not died as The Doctor had believed, but that she and Yrconos fell in love and travelled to Earth in he 20th century. Yrconos took up a career as a professional wrestler, with Peri as his manager. This ending spoils the later revelation of Peris survival in The Ultimate Foe. While the fact of Peri and Yrconos falling in love is consistent with the later story, the rest of it contradicts both televised and novelised versions of the The Ultimate Foe, as well as Peri‘s later appearances in books such as Bad Therapy.However, the revelation in Peri and the Piscon Paradox that the Time Lords created multiple timelines for Per leaves the door open for this variant fate to exist alongside the other fates described for Peri.
