Husband and wife PI team Helen Hawthorne and Phil Sagemont have barely scratched the surface of the world of show cats when a cornered kitty kidnappers claws come out. The one thing celebrity Trish Barrymore and her no-account accountant husband, Mort, can agree on in their bitter divorce is shared cat custody. But when Mort is found brained by a mahogany cat tower, and Justine, their pedigreed Chartreux show cat, goes missing, Trish calls on Helen and Phil. As they await the post-Mort-em, its up to Helen and Phil to find the feline filcher and let the cat out of the bag. Discovering that Mort had some shady dealings within cat show circles, Helen goes undercover as an assistant for a woman who shows prizewinning Persians. As Helen and Phil get deeper into a high-pressure world of primping, posing, and purring to collar a killer, they get caught up in a cat-and-mouse game where the stakes are literally life and death.
