Two twisted and clever killers are at work -maybe even cooperating. One calls himself Casanova and collects beautiful women off college campuses from the Carolinas to Florida. The other, the Gentleman Caller, is terrorising Los Angeles with a series of unspeakable murders. Now, it's a race with time as police detective Alex Cross discovers that his niece, a promising law student, has disappeared - and may be another of Casanova's victims.
