In this high-body-count chiller from the author of The Rosary Girls
, Philadelphia homicide detectives Jessica Balzano and Kevin Byrne are up against a savagely inventive serial killer with a yen for stomach-churning cinema verité. Copycat murders modeled on Psycho
, Fatal Attraction
and other movies are terrorizing the city, as the "auteur" slayer splices film of his bloody re-enactments into rental videos surreptitiously stolen from and then returned to video stores. Byrne, recovering from a near-fatal gunshot wound and swallowing Vicodin like candy, is working half time, so it's up to his eager partner, Balzano, to take the lead in the investigation. Montanari's short, punchy chapters propel the convoluted—and kinky—plot, which caroms between the big-budget movie sets of a Philadelphia filmmaker made good and an underground porn industry where good girls go bad. Several potential perpetrators rear their creepy heads, but the real killer comes out of left field—though readers very attentive to scattered clues won't be too taken aback by the gory denouement. Byrne's awkward relationship with his deaf teenage daughter, Colleen, after his divorce, and Balzano's concern for her precocious three-year-old daughter, Sophie, after she boots her philandering husband (and fellow cop) out of the house, add welcome humanity to a grisly, atmospheric thriller.
