SARAH ROSEN WOULD DO JUST ABOUT anything—even put her own life on the line—to snare the serial killer who made her sister, San Francisco psychiatrist Melanie, his fifth victim. But her worst nightmare can't prepare Sarah for the deadly tango that begins when the psycho suitor, whose romantic streak has earned him the nickname Romeo, starts stalking her. Not only does Sarah come to suspect her nearest and dearest, but the stress triggers flashbacks of horrific memories she has repressed since childhood.
Given the author's past as a psychiatric social worker with high-security inmates, it's not surprising that almost everybody in her debut mystery is either in therapy or should be. But beneath the intermittently thick psychoanalyzing—and the equally copious kinky sex—beats a seductive puzzler as dark as Romeo's heart. (Bantam, $21.95)
