The tenants of Lois Meade's terrace house in Tresham are frustrated by their neighbor's feisty pet cockerel, Satan. His owner, Clem Fitch, refuses to part with his feathery companion-making Lois's tenants fly the coop. Luckily, her son Douglas agrees to rent the house. But when Clem and Satan are found dead, Douglas-who is involved with Clem's daughter-becomes a prime suspect in some foul business.
