Mary Maloney is six months pregnant, she´s a loving housewife and cares deeply about her husband. She is at home, knitting, and she is peacefully waiting for her husband to come home.
Mr. Maloney arrives home to his wife. She takes his jacket and goes to pour their usually drinks for when he gets home. He gulps his drink, which is not something he usually does. Mary begins to offer dinner, he declines. She offers a snack, and he declines again. He asks her to sit, and to listen so he can deliver some unsettling news to her. She goes into shock and cannot believe what he says to her.
Mrs. Maloney keeps calm and collected. She says she is going to get meat, for dinner, from the freezer. She pulls out a leg of lamb and unwraps it. Her face falls flat. SHe approaches Mr. Maloney from behind, throws her arms up and strikes her husband on the back of the head with the leg of lamb. The impact of the hit kills Mr. Maloney. Mrs. Malomey proceeds to put the leg of lamb in the oven to cook it.
Mrs. Maloney does not call the police right away. She goes to the grocer, to have an alliby, and gets food for her (dead) husband! When she came home, she sees her husband lying lifeless and calls the police. They arrive and they check her alliby. She has them drink wine so they relax a little bit, of course so she does not get caught. She then asks them to do her a favor by asking them to eat the lamb that she had ¨made for her husband¨ because she did not feel comfortable eating it.
Mrs. Maloney sat down in the living room while the policemen ate the lamb. She proceeded to giggle. They had no idea that they had rid of all the evidence of the murder.. She got away with everything and lived happily.
Irony, when something that you do not expect to happen, happens. Or, when you know something that a character does not know. The police officers did not know the lamb was the murder weapon and what is ironic about this situation is, is that they said the weapon could literally be under their noses. And it was. They disposed of the murder weapon that was used to kill Mr. Maloney.
