"Death in Heaven" is the twelfth and final episode of the eighth series of the British science fiction television programme Doctor Who. It is the second episode of a two-part story involving the return of the Cybermen and the Master in the form of 'Missy', the first part being "Dark Water", written by Steven Moffat and directed by Rachel Talalay. The episode stars Peter Capaldi, Jenna Coleman, Samuel Anderson, Michelle Gomez, Chris Addison, Jemma Redgrave, and Ingrid Oliver.

The episode received mostly positive reviews, with critics praising its writing, direction, and acting. With Peter Capaldi, Jenna Coleman, Samuel Anderson, and Michelle Gomez receiving widespread acclaim for their performances, Gomez was consistently highly praised in reviews, with many calling her a highlight of the eighth series.

Continuing from "Dark Water", Clara Oswald is trapped with a Cyberman in the headquarters of 3W in St Paul's Cathedral and manages to stop it from killing her by stating that she is really the Doctor.

Outside, the Doctor reels from the revelation that Missy, the woman controlling the Cybermen, is a female incarnation of the Master. The public appears unconcerned by the arrival of the Cybermen, but UNIT, led by Kate Lethbridge-Stewart, turn up and surround the Doctor, Missy, and her group of Cybermen. The Cybermen take to the air using built-in leg jets and scatter over the British Isles. Missy reveals that 91 Cybermen – one for every major population area in the United Kingdom – have been released from St Paul's to explode over graveyards in each populated area, releasing 'Cyberpollen' that will resurrect the dead as Cybermen. Similar events occur all over the world. UNIT renders both Missy and the Doctor unconscious and takes them into custody.
