The Haunting of Villa Diodati (TV story)

The Haunting of Villa Diodati was the eighth episode of series 12 of Doctor Who.

It offered an alternate account of the conception of Frankenstein by Mary Shelley to that of the audio story Mary's Story featuring the Eighth Doctor, though with the story acknowledging that what it was depicting was the result of history becoming unusually flexible around that night.

The episode featured the return of the Cybermen, in their first television appearance since 2017's The Doctor Falls and their first encounter with the Thirteenth Doctor. Specifically, the story properly introduced the Lone Cyberman, as well as its motivations, after he had been mentioned by Jack Harkness in Fugitive of the Judoon.

Synopsis
The Doctor and her companions visit Mary Shelley on the fateful night in 1816 when she creates Frankenstein but all is not as it seems. The rooms of Villa Diodati keep shifting around and ghosts are stalking the halls. And the group soon remember a familiar warning: "Beware the Lone Cyberman. Do not let it have what it wants". But why is Percy Shelley not where he should be according to history?
