Homemade Sin (Callahan Garrity Series #3) by Kathy Hogan Trocheck
With a nose for crime and grime, Callahan Garrity has handled dirty killers on the streets as an Atlanta cop and on the job as a house cleaner. But she's always been able to keep her private life neatly separated from work -- until her cousin, Patti, is found dead. Exchanging her House Mouse cleaning uniform for a detective's cap, Callahan is hellbent to find the culprit. It's notthat she doesn't trust the Atlanta PD. She just knows that her suburbanite cousin's death is too strange to be accidental.
Callahan's search takes her on a convoluted trail from Patti's priest, who may have provided more than spiritual counsel, through Atlanta's inner city and into the shady deals of her cousin's newly prosperous husband. Yet, as the pieces start to fall into place, Callahan faces an even bigger challenge -- staying alive.
