Three main similarities between the movie and text version of Lamb to the Slaughter. Mary denied Patrick's news about him leaving her for another woman that he fell in love with. Mary decided to head off to the grocery store to help cover up her crime to give herself an alibi to when it might have happened. On the other hand, Mary cooks up the evidence or murder weapon, and the police end up eating it.
The difference between the story and the film are the sewing when Mary offers the police coffee instead of whiskey, and the cancellation of dinner plans. In the movie, Mary is not sewing however in the book she is. In the movie instead of Mary sewing, she was setting up the dinner table. In the movie, Mary called a friend to cancel dinner plans.
