Books like The Prisoner of Brenda

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, former patient and owner of No Alibis, Belfast's finest mystery bookshop, to bring his powers of investigation to bear... However, before our hero can even begin, the Man in the White Suit is arrested for the murder of a fellow patient. But is he a double murderer or a helpless scapegoat? Intrigue, conspiracy, and ancient Latin curses all combine to give the Small Bookseller with No Name his most difficult case to date.
