And for one woman, the desperate hunt to uncover his identity becomes a matter of life and death.Professor Fiona Cameron is a psychologist who uses computer technology to track serial offenders. She used to help the police, but vowed never to work with them again when they went against her advice and subsequently botched an investigation.Still smarting from the experience, she's working a case in Spain when her lover, thriller writer Kit Martin, tells her a fellow crime novelist has been murdered. It's not her case, but Fiona can't help taking an interest. When the killer strikes again Fiona finds herself caught in a race against time -- not only to save a life but also to find redemption, both personal and professional.
