By day, Harper Cole trades commodities from his farmhouse in the isolated Mississippi Delta. But at night, Harper serves as system operator for E.R.O.S., a highly exclusive, sexually explicit on-line service whose clients range from the glitterati of Hollywood to the literati of New York. Shielded by a guarantee of absolute anonymity, these clients pour their secrets into the digital confession box of E.R.O.S. Only "sysops" like Harper - the high priests of the system - know and see all. When six female clients inexplicably drop off the network, Harper suspects that something is amiss. But when a world-famous New Orleans author - and E.R.O.S. client - is decapitated in her mansion, Harper breaks the code of silence and contacts the police. They are as shocked as Harper to learn that all six women have been brutally murdered, each with a different weapon, and in a different city. And each time the killer has claimed the same bizarre trophy. Horrified to find himself the prime suspect in the murders he reported, Harper is swept into a secret manhunt led by the FBI's Investigative Support Unit. While the FBI uses the technology of the future and the psychology of the past to trap the brilliant killer, Harper realizes that he alone stands a chance of luring the elusive madman into the open.

24 HOURS —- that's how long it takes a madman to pull off the perfect crime. He's done it before, he'll do it again, and no one can stop him. But this time, he's just picked the wrong family to terrorize. Because Will and Karen Jennings aren't going to watch helplessly as he victimizes them. And they aren't going to let him get away with it.

Jordan Glass, a photojournalist on a well-earned vacation, wanders into a Hong Kong art museum and is puzzled to find fellow patrons eyeing her with curiosity. Minutes later, she stumbles upon a gallery containing a one-artist exhibition called "The Sleeping Women," a mysterious series of paintings that has caused a sensation in the world of modern art. Collectors have come to believe that the canvases depict female nudes not in sleep but in death, and they command millions at auction. When Jordan approaches the last work in the series, she freezes. The face in the painting seems to be her own. This unsettling event hurls her back into a nightmare she has fought desperately to put behind her—for, in fact, the face in the painting belongs not to Jordan but to her twin sister, murdered one year ago. At the urging of the FBI, Jordan becomes both hunter and hunted in a duel with the anonymous artist, a gifted murderer who knows the secret history of Jordan's family, and truths that even she has never had the courage to face.
