Andy McNab is a former member of the British SAS, one of the world's elite special-forces commando units. When he left the regiment in 1993, he was the most decorated active soldier in the British Army. The author of three previous Nick Stone thrillers, Firewall, Crisis Four, and Remote Control, he has also written two nonfiction books about his SAS experiences. He is the only fiction writer whose books are so sensitive that they require vetting by the British Ministry of Defense. For security reasons, Andy McNab's location is classified.
