A killer wants Lilly Echosby to roll over and play dead . . .

Lilly may be losing a husband but she's gaining a toy poodle. That could be seen as a win-win, since her new adopted pooch Aggie (named after Agatha Christie) is cute and adorable, and Lilly's dirty dog of a spouse is cheating on her with a blond bimbo—except for one problem: Albert Echosby’s just been murdered, and Lilly is the number-one suspect.

With the cops barking up the wrong tree, it's a good thing her best friend Scarlett "Dixie" Jefferson from Chattanooga, Tennessee, decided to take a break from the dog club circuit to pay a visit, along with her own prize pair of poodles. With help from Dixie, her defense attorney daughter, and a blue-eyed man in blue with a K-9 partner, Lilly is determined to collar the real killer. But when a second murder occurs, it's clear they're dealing with one sick puppy . . .
