"Death and What Comes Next" is a fantasy short story by British writer Terry Pratchett, part of his Discworld series.
It tells the story of a discussion between Death and a philosopher, in which the philosopher attempts to use the many-worlds interpretation of quantum mechanics to argue that death is not a certainty.
The story was written in 2002 for the now-defunct online puzzle game TimeHunt and the text contains a hidden word puzzle, also devised by Pratchett, which provided a codeword for the game.
Like "Theatre of Cruelty", another of his short stories, Pratchett allowed it to be put on the L-Space Web.
