Colonel Sun is a novel by Kingsley Amis published by Jonathan Cape on 28 March 1968 under the pseudonym "Robert Markham". Colonel Sun is the first James Bond continuation novel published after Ian Fleming's 1964 death. Before writing the novel, Amis wrote two other Bond related works, the literary study The James Bond Dossier and the humorous The Book of Bond. Colonel Sun centres on the fictional British Secret Service operative James Bond and his mission to track down the kidnappers of M, his superior at the Secret Service. During the mission he discovers a communist Chinese plot to cause an international incident. Bond, assisted by a Greek spy working for the Russians, finds M on a small Aegean island, rescues him and kills the two main plotters: Colonel Sun Liang-tan and a former Nazi commander, Von Richter.
