Small-town librarian Kathleen Paulson never wanted to be the crazy cat lady. But after Owen and Hercules followed her home, she realized her mind wasn't playing tricks on her-her cats have magical abilities.

When the body of elderly do-gooder Agatha Shepherd is found near Kath's favorite local café, she knows Owen's talent for turning invisible and Hercules's ability to walk through walls will give the felines access to clues Kath couldn't get without arousing suspicion. Someone is hiding some dark secrets-and it will take a bit of furtive investigating to catch the cold-hearted killer.
