Book excerpt: Mystery shopper Josie Marcus is on the hunt for a killer when a pet store employee mysteriously dies after blowing the whistle on possible puppy mill connections... Josie’s latest assignment is one for the dogs—literally! Pets 4 Luv, a national pet store chain, has hired Josie to mystery shop its St. Louis suburban locations and she discovers possible puppy mill suppliers. When an employee tipster is killed in a suspicious hit-and-run, Josie’s job suddenly gets a lot hairier. Posh pets are a million dollar business for puppy mills; even so, Josie is staggered to think that her sniffing around led to an innocent woman’s murder and may have put her own life at risk. But she’s not ready to tuck her tail and run just yet. Using every bit of her secret shopper savvy, Josie must follow the designer dog trail to expose the illegal breeders, shutter the puppy mills, and finally collar the vicious killer on the loose.
