The lamb in the story has multiple significances. Firstly, it is a literal object, which is used as the murder weapon. Secondly, it represents Mary's innocence in a way at the start. Just as a lamb is often seen as a symbol of meekness and innocence, Mary was like that before her husband's news. But then it becomes a tool for her to commit a crime, which is a kind of ironic twist on the traditional symbol of the lamb.
It might also be a symbol of power or control. If a character has control over the leg of lamb, whether it's in terms of cooking it, serving it, or using it in some other way, it could show their position in the family or social hierarchy within the story. For instance, if a mother is in charge of cooking the leg of lamb, it could show her role as the provider and caregiver in the family. Moreover, if the leg of lamb is stolen or fought over, it would further emphasize its value as a symbol of power.
