Mary Maloney is the wife of Patrick Maloney and is 6 months pregnant. She is very ecstatic, but also has a vengeful side to her. She would be flat because we learn very few things about her. Mary would be dynamic because she starts as a kind wife and ends as a divorced killer who lost her mind.
Patrick Maloney is a hardworking man. In the beginning it seems like he's a very good husband, but we find out later, that's not true. He's flat because we only get a brief description of what he's like. He's also static because he does not get to grow or learn because he gets killed.
There are some different moods in the story, one of them being mysterious because we don't know exactly what Patrick had told Mary to make her go crazy. It also has a fairly grim mood because Mary killed her husband with a lamb chop knowing she was pregnant and the consequences for murder would be death.
