The Doctor plays cricket, Nyssa gets a doppelgänger, and someone really should have called Miss Marple.
Short Synopsis
The Doctor and friends stumble into a 1920s country estate party, where mistaken identity, secret family scandals, and a murderous brother in the attic make for two episodes of very polite chaos.
Extended Storyline
The TARDIS lands in 1925 England, where the Doctor is immediately roped into a game of cricket. Naturally, he’s brilliant at it (because apparently Time Lords play space cricket at Gallifrey Academy). This leads to the entire crew being invited to a fancy-dress ball at the local country house, because that’s how life works when you’re the Doctor.
Once at the estate, Nyssa discovers she’s the spitting image of Ann Talbot, the Lady of the House. Rather than question this cosmic coincidence too deeply, everyone just rolls with it. The upside? Nyssa gets to play a double role. The downside? So do we.
Meanwhile, the household harbors a dark secret: George Cranleigh, Ann’s fiancé’s brother, was horribly disfigured in a South American fire and kept hidden away in the attic. (Because apparently Jane Eyre and Phantom of the Opera were both on Saward’s reading list.) George is mentally unstable, mute, and rather murdery, which becomes a problem when he escapes and starts throttling random party guests.
Naturally, suspicion falls on the Doctor, because nothing says “innocent party guest” like turning up uninvited in strange clothes and wandering around crime scenes. The local constabulary arrests him, and for a while it looks like we’re in for Midsomer Murders: Time Lord Edition.
Eventually, the truth comes out when George kidnaps Ann and flees up onto the roof of the mansion. The Doctor and company try to talk him down, but George tragically falls to his death. The police apologize for suspecting the Doctor, everyone acts like this is a totally normal weekend in 1920s high society, and the TARDIS crew quietly sneaks away before anyone asks too many follow-up questions.
