When a last-minute opportunity arises to accompany her boss to an art auction in Atlanta, Lilly throws some money at the problem of where to board her toy poodle Aggie (short for Agatha Christie). Posh Pet Haven offers the most luxurious canine accommodations in all of Chattanooga, Tennessee. The place even provides pet cams so anxious owners can check in on their pampered pooches.

But when Lilly tries to take a peek at her poodle, she gets a terrible shock-she witnesses what she's sure is a murder. She thinks the victim may be the wealthy co-owner of Pet Haven. The police follow her lead but find no body, no evidence of a crime, and no video record. Starting to feel like the dog owner who cried wolf, Lilly decides to go undercover to catch a killer who may be hiding in plain sight . . .
