Three generations of the Leonides family live together in a large, if somewhat crooked looking, house. Then the wealthy patriarch of the household, Aristide, is murdered. Suspicion falls on the whole household, including Aristide’s two sons, his widow – fifty years his junior – and even his three grandchildren. Could any member of this seemingly devoted family have had a hand in his death? Can Charles Hayward, fiance of the late millionaire’s granddaughter, help the police find the killer?
