However, tranquility is shattered when Jo's archnemesis, the notorious local troublemaker Homer Kimball, is found dead near her bookshop.

As the gossip mill starts churning, Maisy becomes the prime suspect, thanks to a heated argument she had with the victim about the death of Great-Aunt Jo. Homer claimed that Maisy's aunt got what she deserved, sparking another round of fights just before the tragic event.
