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.

When Callahan Garrity gets caught in a liquor store holdup on the way home from a St. Paddy's Day party, one of her best friends is shot. Callahan and her House Mouse cleaning crew dive into the investigation--only to discover that her old friend might have been working both sides of the law as an accomplice in a string of robberies. It will take every trick they've got to pierce the veil of secrecy surrounding an Irish police organization and prove that the case is more than it seems.
