the lamb story thing

I think that in the story the guy that wrote it wanted us to think that the wife was not able to commit a crime like that. I think that the writer wanted to build up the suspense and make us think that she was just going to make dinner for her husband but then she just didn't and she hit him in the back of the head with a large piece of lamb. Then the writer just tried to make it look like she was going to get caught and then she didn't because she had all of the cops eat all the evidence that she could have possibly have had anything to do with it.
