Is it a mystery...? or is it suspense.?

I think this story is more of a mystery than a suspense, because the cops don't know what exactly happened to Ms. Maloney's husband, and since they ate the murder weapon they'll never find out. This story is an example of a dramatic irony, the readers know something that the characters in the story don't. In the beginning of the story Ms. Maloney seems like a loving housewife, who takes care of her husband. When Mr. Maloney comes home from work and refuses to eat supper or anything his wife asked him he confesses whats on his mind, and that was that he's divorcing her. She over reacted and hit him over the head with the lamb leg that was for dinner. Covering up her tracks Ms. Maloney puts the lamb into the oven and goes upstairs to clean up and go to the grocery store. When she calls the police after she gets back from shopping she acts like she doesnt know what happened and that she loved her husband. This shows that even though Ms. Maloney acted like the perfect house wife, she decieved her husband. The red herring is found in the very beginning of the story, when Ms. Maloney is made out to seem like a loving wife to her husband. This is an example of poetic justice because even tho she killed her husband she got away with it.
