The police finally capture Electric Bill, London's most infamous kidnapper. But they can't find Kate Jennings, his latest victim and the daughter of a wealthy lord. DI Annie Guthrie sends Murphy undercover to Bellview Prison to pull a confession from Bill. When the plan is threatened from within, the lives of both Kate and Murphy hang by a thread.

Pool hall legend Mickey Munday faces three problems: a handsome young rival, a colorful past, and the Irish terrorist organization that wants him to rig his game-or else. Someone tried to kill him in Spain, so when he comes to London for the championships, Murphy and Annie pose as his bodyguards. The stakes get even higher when Munday's long-lost daughter appears.
