Lamb to the Slaughter
The Lamb to the Slaughter is about a women named Mary Maloney. She loves her husband so much that she seems to be a little too obsessive. One day he comes home from work drinking a lot and wants a divorce. She tells herself to just go on like nothing happened. She goes to cook dinner and she gets a lamb leg out of the freezer. She comes up behind Mr. Maloney and smacks him in the back of the head with the lamb leg, killing him. She calls the cops and tells them she doesn’t know who killed him or how he was killed, and that she found him like that on her way back from the store. She offered them something to eat, so they did. She fed them the only evidence, the lamb leg.
The second type of irony is dramatic irony. Mary Maloney kills her husband with a lamb leg. When she calls the cops they have no idea who killed Mr. Maloney or what he was killed with and the reader does. She cooks the evidence and has the cops eat it and one of the cops says, "It's probably right under our noses." What he didn't know was that it literally was as they were putting it into their mouth.
