The battered body of a young woman is found floating in the still waters of a city canal. Police suspect a serial killer, which makes it a case for the Serious Crime Squad. Not Charlie Resnick's case, then; not his worry. But soon another victim is found, and this time, Charlie has a personal interest. His lover, Hannah, knew the dead woman--knew, too, that her husband was uncontrollably jealous and very free with his fists.
