Patrick Petrella

Patrick Petrella is a fictional police detective created by the British mystery writer Michael Gilbert who appears in ten books published between 1959 and 2003 and is probably the best-known of the half-dozen or so recurring characters that Gilbert wrote about throughout his long career. He is the protagonist of two novels and of 54 short stories that were first published in magazines and newspapers and then republished in eight collections of stories. In one of the short stories, however, "The Spoilers", in Game Without Rules, featuring Mr. Calder and Mr. Behrens as the protagonists, he appears only very briefly, at the end of the story. In his first appearance in a novel, the 1959 police procedural Blood and Judgement, Petrella is a "probationary" Detective Sergeant at the (fictional) Q Division of the London Metropolitan Police. By the final novel in the series, Roller Coaster, he has worked his way up to become a Superintendent.
