A dead husband. A brilliant hacker. A shadowy world of sex and money in a den of academic intrigue. Madeline Geiger is a young computer scientist whose husband has recently died under suspicious circumstances. On the day of his funeral, Madeline is approached by an FBI agent who persuades her to go undercover in the Computer Science Department to find out who's providing encryption software to an illicit pornography ring. Madeline is an introverted nerd and definitely not a spy. And when she delves into the computers of her colleagues, she makes some devastating discoveries about her late husband and co-workers. Someone in her orbit is a killer who is onto her and has already murdered once. In order to survive, Madeline must emerge from the shadow of her late husband and outwit an antagonist who is luring her into a deadly game.
