Shady private investigator Lennox is a hard man in a hard city at a hard time: Glasgow, 1953, where the war may be over but the battle for the streets is just beginning. It's a place where only the toughest and most ruthless survive. The McGahern twins were on the way up until Tam, the brains of the outfit, opened his door to find two hitmen pointing shotguns at him. The Three Kings, the crime lords who run Glasgow's underworld, all deny ordering the hit, so Tam's brother Frankie turns to Lennox to find out who killed his twin. Lennox refuses. Later that night, Frankie's body is discovered on the road, his head mashed to pulp, and Lennox finds himself in the frame for murder. The only way of proving his innocence is to solve the crime - but he'll have to dodge men more deadly than Glasgow's crime bosses before he gets any answers.
