It's Police Detective Dino LaStanza's first week in Homicide and he must handle the horrific murder of Marie Sumner, slashed to death on a quiet French Quarter street. LaStanza and his partners work long, frustrating hours with no results. When another woman is slashed to death along Bayou St. John, the detectives bear witness to the carnage again. LaStanza feels even worse this time, almost useless. The media labels the killer "The Slasher" and when he strikes a third time, murdering the daughter of a wealthy banker, LaStanza meets a young woman who changes his life.
Lizette Marie Louvier is an alluring, intelligent young woman, a dark haired, uptown beauty beyond LaStanza's reach and yet the attraction between the two is undeniable. The unrelenting pressure in the homicide pressure cooker grows as LaStanza and his partners track a monstrous killer through the dark streets of the murder capital of the US, hoping they can catch him before he kills again.
