Dervish is Digital
Detective Lieutenant Doré Konstantin is up against it.
Konstantin is Chief Officer in charge of TechnoCrime, Artificial Reality Division. It sounds better than it is – in fact, the AR Division consists of three people and a case load of nearly impossible to solve crimes.
Now, as if handling her heavy case load almost single-handed weren't bad enough, she's got a stalker to deal with.
A woman named Susannah Ell claims that she is being stalked by her ex-husband, Hasting Dervish. It seems implausible at first – Dervish is an extraordinarily rich and powerful man, who should have better things to do. But as Konstantin starts to look into it, she discovers that it's not quite so impossible to believe: Dervish has traded places with an Artificial Intelligence, and is busy committing crimes no one has ever thought of before.

Pat Cadigan
Pat Cadigan (born 1953) is an American-born science fiction author, who emigrated to England in 1996. Her work is described as part of the cyberpunk movement. Her novels and stories all share a common theme, exploring the relationship between the human mind and technology.
Pat Cadigan's first novel, Mindplayers (1987), introduces what becomes the common theme to all her works. Her stories blur the line between reality and perception by making the human mind a real and explorable place. Her second novel, Synners (1991), expands upon the same theme, and both feature a future where direct access to the mind via technology is possible. While her stories include many of the gritty, unvarnished characteristics of the cyberpunk genre, she further specializes in this exploration of the speculative relationship between technology and the perceptions of the human mind.
