Crooked house

Three generations of the Leonides family live together in a large, if somewhat crooked looking, house. Then the wealthy patriarch, 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 and clear his loved one's name?Christie always acknowledged this novel as one of her favourites. She said in an interview in The Sunday Times that she enjoyed best writing the Crooked House type novel, "which depends on a family and the interplay of their lives."
