The Doctor takes Tamsin on a long (long) tour of the TARDIS. After three hours of exploring, she's concluded that she should have worn better shoes, she hates the room with the seagulls, and she should have known that he'd be, you know, [[UnusualEuphemism a single man with a cat]]. The Doctor protests that he's not, and also that he doesn't own a cat. His cat disagrees.

While attempting to get rid of the mysterious pet, he and Tamsin end up on a planet that's ''obsessed'' with Creator/EdgarAllanPoe. The Doctor finds himself forced to recite eight paragraphs of "Literature/TheRaven" from memory, battle giant raven robots, hear far too much about a "red death", rescue Tamsin from a hallucinatory live burial, rescue ''himself'' from a hallucinatory pit and pendulum, fight off a giant shadowy black cat, and rescue the local evil mastermind from being consumed -- quite literally -- by her own fear. Luckily, the poetically inclined Eighth Doctor is quite at home in a Poe-inspired world, especially since he happens to have [[Literature/EighthDoctorAdventures briefly met Poe]] during the author's final days of insanity.

Also, he discovers that there's been another Time Lord meddling with things, but since [[Recap/DoctorWhoTVMTheTVMovie the usual suspect is no longer around]], he shrugs it off for now.

It turns out that the Time Lords set up the planet as a prison colony, and the Doctor was used by them to grant the prisoner absolution. The Doctor manages to throw out the meddling Gallifreyan cat in the end, but not before it reminds him that [[Recap/BigFinishDoctorWhoNEDAS4E4TheBookOfKells he's not the only rogue Time Lord out there]].
