To Live & Die in Dixie by Kathy Hogan Trocheck

From her time on the Atlanta police force, Callahan Garrity, house cleaner and private investigator extraordinaire, 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 discover the bloodied body of a young woman in a bedroom -- and are soon on the trail of a priceless Civil War diary stolen by the killer. As if two crimes aren't enough, deadly serious collectors, right-wing radicals, and impulsive teenagers make the case even more difficult to tidy up ... and more dangerous.
