Mary Maloney, pregnant with her first child, was patiently waiting for her husband Patrick to return from work. When he arrived, she made two drinks for them, as usually.
Patrick said he would not go out for dinner with Mary, and would not have dinner with she at home. And he told her something that shocked her for a moment.
Mary could not believe in that she heard, so she decided to thaw a leg of lamb for dinner. But Patrick insisted that he would not have dinner with her tonight.
Unhappy with the situation, Mary hits Patrick's head with the leg of the lamb. He took about 5 seconds to fall to the ground. Desperate, Mary decided to change the scene of the crime in her favor.
Mary put the leg of lamb in the oven, dressed up and went to the grocery store bought some things for dinner, there, she told Sam how happy she was to make dinner for his beloved husband. And when she got home, she called the police.
When the police arrived, tried to find the murder weapon, but without success. Mary offered the lamb's leg for them to dinner, hardly knowing they were eating the murder weapon.
