In the beginning of the story there's a husband named Patrick and a wife named Mary. Mary is a caring housewife who is also 6 months pregnant. Patrick isn't so caring because he's barely home and doesn't treat her right. One day Patrick decides he's going to leave Mary.
I want a divorce
Here you go Dear
Mary got angry and upset because Patrick wanted to leave her. She ended up going to the kitchen grabbing a frozen lamb leg and hitting him with it, which instantly killed him. Mary starts freaking out because of what she's just done and decides she needs a plan to cover the murder. Mary puts the lamb in the oven but doesn't turn it on, then she creates her own crime scene and calls the police/investigators.
WHAT DID I DO?!
The investigators were trying to find any evidence that could lead to the murder but they couldn't find anything. Mary was still freaking out because she was nervous they would find something. Then one of the investigators mentioned that there was a lamb leg in the oven but it's not cooking, so she gets up and goes to cook it. Before the investigators left she offers them something to eat and feeds them the lamb.
