This story is about Mary Maloney and her husband Patrick who was a detective. It seems that she loved her husband dearly. But shockingly she killed him when he told her that he was going to leave her. As she had lived with a detective husband, she knew the ways to prove herself innocent from the charge of murdering him. She went to a grocery shop to buy some edibles and behaved as if nothing had happened. She told the grocer, Mr. Sam that she was buying those edibles for her husband. After coming home, she rang up the police and the detectives and informed them about the murder of her husband, Patrick. Investigations went on, but in vain. Nobody could raise a finger of suspicion on Mary Maloney as there was no evidence against her. Thus, a murderer moves freely in the society.
