Detective Ruben Montoya ("Cold Blooded") is back, investigating the murder of a local shock jock and a female college student headed for a nunnery. Still grieving the loss of his lover Marta, the last thing he wants is to get involved with the prime suspect - the victim's wife Abby Chastain.
As more victims start to pile up, it is obvious that there is a serial killer on the loose, and all points lead to the Our Lady of Virtues convent and mental hospital, where Abby's mother plunged to her death decades earlier. Each set of victims are polar opposites of each other, adding to the mystery. While Ruben does not believe that Abby is the culprit, she is somehow integral to the killer's motivation - finding out why just might get them both killed.
Jackson does a great job keeping the killer under wraps (so much so that we are not aware of him until the final act); throwing out numerous possible suspects. The killer's inspired MO is clever and ingenious. But the revelation of the culprit was a let down after such a gripping tale, marring what could have been a perfect story.
