Kathleen is excited to meet three old pals of her beau, Detective Marcus Gordon, while they visit charming Mayville Heights on business. But the reunion is cut short when one of the friends is killed--and the evidence points toward Marcus as the murderer.

Though it seems she doesn't know all of Marcus's secrets, Kathleen is sure he's no killer. With his suspect status sidelining him from investigating the case, it's up to Kathleen and her feline partners-in-crime to find whoever is framing Marcus--and make sure the good detective hasn't found his last clue.
