Callahan Garrity is the owner of House Mouse, a cleaning service that tidies up after Atlanta's elite. She's also a former cop and a part-time sleuth. She and her coterie of devoted helpers can ransack a house for clues faster than it takes a fingerprint to set. From her time on the Atlanta police force, Callahan has excelled at mopping up messes of all kinds. But she has no idea what she's getting into when she agrees to work for infamous antiques dealer Elliot Littlefield. The first day on the job, she and her crew are on the trail of a stolen Civil War diary. Soon they are tangling with deadly serious collectors, right-wing radicals, and impulsive teenagers, all of which make the case even more difficult to solve.
