Mrs. Maloney was excited for her husband to get home. She feels calm and happy.
Mr. Maloney arrived home. Mary made him a drink, and he drank it very quickly, which was unusual. He got up and got himself another drink afterward, and drank that one quickly too.
Come quick! He's dead! My husband is dead!
Mr. Maloney told Mary that he was going to divorce. Mary is shocked and goes downstairs to get a leg of lamb to cook.
Have some lamb, you'd be doing me a favor. Hee hee!
Mrs. Maloney kills her husband with the lamb, and then calms down and goes to the market to create an alibi.
She goes home and "finds" her husband dead. She is very sad and calls the police to investigate. They don't suspect her and feel a lot of pity for her. They are trying to find the weapon, because they say "get the weapon, and you've got the man.
The detectives eat the lamb, the murder weapon itself, and the story ends. "Lamb to the Slaughter" is a story about Mrs. Mary Maloney, who murders her husband and gets away with it. The reason she killed him was because he was leaving her, and she killed him a leg of lamb. She was clever when she had to get away with it, and her alibi was flawless. She acted very innocent and the police only felt sorry for her. She even made the detectives eat the murder weapon without suspecting a thing.
