The Burgess Collection consists of the first draft of the unpublished novel Puma, written in 1976 as a film treatment that was never made into a film. The novel is accompanied by a letter of explanation from Brian Kirby to Jim O'Roark, February 7, 1979.

Portions of the novel, which was pitched as an update of the classic film When Worlds Collide and which would have told the story of a planet [named "Puma"] hurtling towards Earth, was later adapted by Burgess into his 1982 novel The End of the World News.
