Someone is targeting the members of the elite intelligence unit known as "the Prime Minister's private army" and all those who work with them. On Long Island, a trusted operative for the President nudges his boat up to a pier, when a man materializes out of the rain and shoots him. In London, General Charles Ferguson, advisor to the Prime Minister, approaches his car on a side street, when there is a flash, and the car explodes. In New York, a former British soldier takes a short walk when a man comes up fast behind him, a pistol in his hand. For Sean Dillon the hunt is on. A very well-connected old nemesis has clearly become tired of the private army's interference in his schemes. But proving it is going to be a difficult task, and surviving it the hardest task of all . . .
