Lord of the Fleas — Kassandra Lamb

What could be more innocent than a country flea market? When service dog trainer Marcia Banks takes up temporary residence with her best friend, her goals are simple: spoil her toddler godchildren and train her newest dog's veteran owner, a vendor at a local flea market. But when the owner of the flea market is found dead and her client is a prime suspect, she discovers that nothing is as it seems, including the victim himself. Even her guileless client puts her in a double bind when he shares, in confidence, something that local law enforcement would love to know. The only way out of her dilemma seems to be to find the real killer. The flea market, however, is hiding more secrets, and some of them could be deadly.
