Saguaro

In the late 1970s, a diabolical killer stalks the streets of Tucson, Arizona. Viciously striking at random and leaving no clues, the killer thrusts the city and its residents into a state of terror. Law enforcement and private citizens are desperate to uncover the identity of the monster dubbed the Saguaro Sadist and stop his bloody reign of fear and death.

A motley crew stands up to investigate, including two police detectives battling their own demons, a famous author whose interest in the city is unusual at best, several college professors of anthropology and criminology, a British expatriate PI, a psychic witch from Salem, two sets of twins from New Orleans, and a determined but grieving Cajun cop from the Big Easy.

As the bodies pile up, it becomes clear that unless the culprit is caught, he will disappear into history. Why? Because this isnt the first such suite of murders, and that murderer was never caught. Has he begun reimagining his old crimes, or has someone taken up his mantle in a most savage way?
