Raymond Chandler once proclaimed that the first-person narrator should never turn out to be the villain in a good mystery or thriller. Luckily, the excellent writer Greg Iles has seemingly ignored Chandler's advice. Iles has created a character--Harper Cole, a futures trader and online pornographer--who could very well be the person killing off subscribers to his Internet sex service. Or is it Miles Turner, Cole's very odd colleague? If you thought that stalking a killer on the Internet had been done to death in books and bad movies, this one will have you pushing the reload button on your browser. Other Iles books in paperback include Black Cross and Spandau Phoenix . Successful commodities trader Harper Cole, who moonlights as a systems operator for computer sex-line EROS, works via computer from his home in Rain, Mississippi. When several EROS regulars suddenly disappear, Harper suspects foul play. His subsequent report to the police leads to a manhunt for a diabolical genius stalking his prey through the EROS network. When the FBI fails to capture the killer, Harper and friend Miles masquerade online as a potential victim, using the persona of Harper's sister-in-law as bait. Events escalate, and Harper and wife Dr. Drewe Cole become trapped in a personal struggle with the madman as his lethal attacks strike ever closer to home. Iles (Black Cross, LJ 11/15/94) scores high with this psychological thriller, easily accessible even to the computer-semiliterate. Though a bit too long, allowing for predictability at the end, it is still a chilling roller-coaster ride all the same. Recommended?Lori Dunn, Montgomery Cty. P.L., Troy, N.C. Copyright 1997 Reed Business Information, Inc. Iles displays a flair for pushing topical hot buttons in his third thriller. The story kicks off with the gruesome murder of New Orleans horror novelist Karin Wheat. From there, we move into a plot involving telecommuting, hackers, cybersex, and the supposed regenerative properties of melatonin. Sensitive guy Harper Cole lives with his physician wife Drewe in his ancestral farmhouse in Mississippi, but he makes his living trading options on the Chicago exchanges and working as a sysop for a New York^-based online service called EROS (for Erotic Realtime Online Stimulation). When female EROS clients--including Karin Wheat--start disappearing from their online haunts, Harper suspects foul play and phones in a tip to the New Orleans police. His suspicions are confirmed when the bodies of the missing women start turning up around the country, but as the only known link between them, he's the prime suspect in the murders. In order to prove his innocence, he must smoke out the killer by creating an irresistible female online persona, putting himself and his family squarely in the line of fire. As in the author's first two novels, Spandau Phoenix (1993) and Black Cross (1994), there's a master-race theme at work here--the killer is a Nietzsche-quoting scientist looking for the secret of eternal youth (and a nice Aryan girl) in all the wrong places. This is a bit light for serious techno-thriller buffs, but it should be popular among the AOL chat-room crowd. June Vigor An exuberant if somewhat hokey computer age serial-killer- thriller combines voyeuristic sex, Internet technobabble, tedious brain research, and southern-fried soap opera with a high degree of stay-up-all-night suspense. Can you hate a novel that hacks off Anne Rice's head in the first chapter? Shaken by the news of the gory murder of New Orleans gothic horror novelist ``Karin Wheat,'' Harper Cole, a self-made commodities trader and secret systems operator of EROS, an upscale Internet sex-chat service, knows that when Wheat wasn't pounding out bestselling terror tales, she was sharing her deepest erotic fantasies with other pseudonymous EROS members, six of whom have been mysteriously murdered within the last year. Fearing that the killer has gained access to EROS's secret files, Cole, who labors in obscurity from a home office hidden among Mississippi cotton fields, calls the New Orleans police and thus brings calamity on himself, his hardworking ob/gyn wife, his sexpot sister-in-law Erin, fatherly FBI forensic psychiatrist Arthur Lenz, and Cole's best friend, eccentric computer genius Miles Turner, creator of the EROS network. To lure the serial killer into revealing himself, Cole goes online pretending to be Erin, a tactic whose gender- switching eroticism is never realized as Iles (Black Cross, 1995, etc.) dumps a fishmonger's cart of red herrings in Cole's path. The villain is a typically brilliant homicidal bermensch who confounds the best effor
