This is New Orleans - 1947. It starts as a wandering daughter case when a pretty widow hires New Orleans private eye Lucien Caye to find her 22-year-old daughter. Helen Croix walks into Caye's office with a picture of her missing daughter, Madelyn. She warns Lucien he'll be tempted when he finds the alluring strawberry-blond temptress. Madelyn Croix will most likely seduce him. Helen describes her daughter as rapacious. Lucien has to look up the word to discover it means avaricious, greedy, ravenous - subsisting on live prey.
On Madelyn's trail, Lucien comes across a lovesick lawyer, a seedy photographer, a suspicious psychiatrist, a jealous husband, the worst private eye in New Orleans, a mischievous black kitten, and a bevy of pretty women willing to bed him. Shortly after the lovesick lawyer is murdered, Madelyn Croix comes to Lucien one night with that curvaceous body and Prussian-blue eyes that blink ever so slowly, precisely, like a falcon, and he realizes - rapacious, like a raptor, a bird of prey. Madelyn hires Lucien to protect her. Someone is trying to kill her.
