Male child,love and lamb to the slaughter.Which do I prefer?

I prefer the story called LAMB TO THE SLAUGHTER.I like the story because it gave us an idea that the Mary Maloney was a very good housekeeper and was also a perfect wife totally in love with her husband in the first paragraph.But in the end,the last few paragraphs gave us the idea of how shrewed,calculating,uncaring and emotionless she was after she murdered her husband.It gave us a twist in the story.hence i prefer this story the most.
