I came home and found him like this.
Mrs. Maloney kills her husband with the leg of the lamb on his dinner plate.
Mrs. Maloney is married to a detective. She was waiting for her husband to come home; she was so excited. Her husband tells her that he wants a divorce, so she takes the lamb from the dinner plate and murders him. She didn't know he was going to say that. So she wasn't planning on doing that. She calls the cops and has them come over to investigate the scene. She asks the cops if they want to have some lamb; referring to the murder weapon. They eat up the evidence and she gets away with murder.
Mrs. Maloney calls the cops so they can come over and "find out" who killed him.
The cops come to her house to figure out who was the murderer.
Mrs. Maloney asks the cops if they're hungry, and then feeds them the leg that she used to kill her husband; they ate the evidence. She giggled to herself because she got away with murder and the murder weapon was right under their noses.
