First published in 1974, this novel is a semi-autobiographical reflection on the author's experience of having been the subject of Stanley Kubrick's film adaptation of A Clockwork Orange in 1971. This is the end of Enderby, Anthony Burgess's finest comic creation. Dyspeptic and obese, this is the account of his last day as a visiting professor in New York, and his last day on Earth.

The Irwell Edition of The Clockwork Testament will provide new information about the genesis of the novel, gleaned from a series of drafts and typescripts recently discovered in the archive of the International Anthony Burgess Foundation (IABF) in Manchester, as well as printing a deleted chapter for the first time in English.
