"As a child, Eve Dallas was found on the streets. To escape her past, she built a new identity and a new future as a cop in New York City. Now the hard-edged and cool-headed Eve fights for truth and justice, but she still has one very human weakness. . . the enigmatic Irish billionaire Roarke. The year is 2059. It is a future in which technology and humanity collide, and a new computer virus has become the latest form of terrorism. Reva Ewing, a former member of the Secret Service, a security specialist for Roarke Enterprises, is a prime suspect in a double homicide. She had every reason to want to kill her husband, the renowned artist Blair Bissel. Not only was he having an affair, he was having it with her best friend. But Lieutenant Eve Dallas, who's on the case, believes Reva is innocent. Eve's instincts tell her that the murder scene looks too perfectly staged, the apparent answers too obvious. And when she digs for more, she discovers that at nearly the exact time a kitchen knife was jammed into the victim's ribs, the passcode to his art studio was changed - and all of the data on his computer deliberately corrupted."; 7¾" - 9¾" Tall .
