Book excerpt: Deadly Messenger centers around an FBI agent in pursuit of a serial killer known to stalk and attack women he meets while chatting on the Internet. Special Agent John Logan has been on the appropriately dubbed Cyber-Slasher case for almost seven years. Always seeming to be one step behind the killer, he's yet to make a substantial break and his superiors are threatening to pull him from the case. Although the killer's method of operation varies from case to case, two keys link them all''the use of a rare anesthetic, Phenyltetrizine, and the victim's intimate association with a mysterious stranger on the Internet. Can Logan catch the killer before someone close to him becomes the next victim?
