Loverboy and Bad Girl

A consensual union between a lustful young lady and a nameless stud kicks off this clunky thriller by Jaffe (Bad Girl, etc.), in which a serial killer taunts the FBI with clues to his next murder. After the sweaty prelude, Imogen Page, an FBI special agent with a rare gift of synthesis a mingling of the senses that renders her empathetic to the motivations of others, even criminals is called to Las Vegas, where noted nuclear physicist Dr. Rosalind Carnow is missing from her hotel, presumably kidnapped. A collage rather than a ransom note tells authorities she's in the hands of the "Hide and Seek Killer," aka Loverboy: as usual, he gives them two and a half weeks to solve a dozen or more riddles and find the victim before he kills her. It's a game this wily, sadistic killer has won five times before. Imogen, though still grieving the sudden death of her beloved only brother, is persuaded to take the case.
