Stalking Horse by Terence Strong

After six years in deep cover to penetrate the IRA, Max Avery was a man on the edge. A man starting to crack, and wanting out. But London and Washington had other ideas. Iraq had invaded Kuwait and Saddam Hussein threatened a terror strike to win him the Gulf War before it began. They needed a stalking horse to get close to the enemy—and Avery was their man, whether he liked it or not. Plunged into a nightmare mission with the SAS and the American Delta Force, Avery finds his wife, his future, and his very life on the line.
