In "Lamb to the Slaughter," by Roald Dahl, a man is killed by his pregnant wife. She kills him because he tells her something she doesn't want to hear. When she goes to make dinner, she takes a leg of lamb out of the freezer and uses it as a club to hit her husband over the back of the head. She goes to get some groceries. When she comes back, she calls the police and says someone else killed her husband. When the police come, she gives them dinner – the leg of lamb, the only piece of evidence.
