The Haunting of Villa Diodati

Ghost stories, stormy nights, and one half-finished Cyberman ready to ruin Byron’s poetry reading.

Short Synopsis

The Doctor takes the gang to 1816 to meet Mary Shelley and friends, but instead of romantic banter and proto-horror, they find themselves battling a rogue Cyberman in a haunted house with more doors than logic should allow.

Extended Storyline

We begin in Switzerland, 1816—the infamous “year without a summer,” when a volcanic eruption left the skies gloomy enough to inspire Mary Shelley’s Frankenstein. The Doctor, thrilled to let the fam meet some literary heavyweights, lands them smack at the Villa Diodati, home to Lord Byron, Percy Bysshe Shelley, and Mary herself. The plan? Listen to some poetry, maybe dance, definitely avoid interfering with history.

Naturally, the plan lasts about three minutes.

First, the house itself is misbehaving. Doors refuse to lead to the same room twice, windows open onto impossible views, and shadows stalk the guests. Mary, Byron, Percy, and Claire Clairmont are all on edge—well, except Byron, who seems mostly concerned with flirting shamelessly with literally anyone who moves (including, awkwardly, the Doctor). Ryan is unnerved, Graham tries ghost jokes, and Yaz is—well, Yaz is possibly developing a bit of a crush on Mary.

Then things get properly weird: Percy Shelley is missing, the house seems “folded in on itself,” and strange lightning keeps flickering outside. When the truth emerges, it’s not ghosts at all (sorry, Graham), but a Cyberman signal warping reality.

Enter Ashad: a lone, partially-converted Cyberman. And not the clean, uniform “delete-delete” model, but a horrifying patchwork of metal and flesh, with one exposed hand still very human. He’s half-finished, half-insane, and wholly terrifying. Ashad’s mission is simple: retrieve the “Cyberium,” a glowing liquid metal containing all the strategic knowledge of the Cyber Empire, which has somehow bonded with Percy Shelley. Yes—Mary Shelley’s poet husband has been turned into the living USB stick for robot Armageddon.

The Doctor faces a brutal choice: let Ashad take the Cyberium and restore the Cybermen (dooming billions in the future), or protect Shelley, preserving history but potentially destroying humanity’s only hope of resisting the Cyber Army. After some agonizing, the Doctor makes the cold call: Shelley must suffer, and the Cyberium must be given up. It’s one of Jodie Whittaker’s strongest moments, as she snarls at her companions: “Sometimes, this team structure isn’t flat—it’s mountainous, with me at the summit, and it’s my decision!” Ouch. Democratic space family, shattered.

Ashad absorbs the Cyberium and vanishes, leaving the group shaken and history forever altered. Mary, however, has found her inspiration—turning the nightmare of half-flesh, half-machine into the seed of Frankenstein. Which, if you think about it, is possibly the darkest “fun fact” about literary origins ever told by Doctor Who.
