For the coach of the Springfield College soccer team, see John Brock (soccer).
John Brock is a fictional British undercover agent created by Desmond Skirrow. He appeared in three fast-paced, witty, and irreverent spy novels written in the late 1960s. Like his creator, he is an advertising executive in London but he is also a part-time agent for a secret department run by The Fat Man. He is tough, witty, and supremely competent.
