When notorious gangster 'Fat Sam' Mahood is murdered, the chief suspect is arrested nearby. But he seems to have suffered a breakdown. Incarcerated in a mental institution, he's known only as the Man in the White Suit. The suspect remains an enigma until Nurse Brenda calls on Mystery Man, Belfast's finest mystery bookshop owner, to bring his powers of investigation to bear...
