Requite — E.H. Reinhard

Tampa homicide lieutenant Carl Kane is enjoying a new work schedule, a budding romance off duty, and a lull in recent murders -- that is, until he's requested to a murder scene in a neighboring district. A seemingly normal husband and wife are found bludgeoned to death with words carved into their flesh. The partial message left in the victims ensures more bodies will follow. It doesn't take long before they do. Kane quickly realizes that this is revenge in its most sinister form. He must bring the man behind the murders to justice before the message is complete, the body count rises, and the killer disappears forever. A tall task when everyone involved is either dead or deceitful.
