Doctor and Ace infiltrate Peinforte's nest

The Doctor and Ace materialize on the landing of Lady Peinforte’s home, a 17th-century Windsor estate, and immediately sense they’ve stepped into a place of lurking danger. Quietly avoiding detection, they discover the body of the Mathematician, Lady Peinforte’s latest victim, slumped over a chessboard after calculating the precise date of the Nemesis comet’s devastation: November 23, 1988. The Doctor uncovers how the comet’s metal formed a statue that now anchors Peinforte’s sinister ritual, linking her obsession to neo-Nazi plots. Ace’s unease grows as the Doctor pieces together the lethal convergence—past and future adversaries bound by cosmic doom. key_dialogue: [ DOCTOR: Stay where you are. ACE: What? DOCTOR: Something you don't want to see. ]
