Crossfire — Andy McNab

Body guarding a TV crew on the streets of war-torn Basra, ex-deniable operator Nick Stone's life is saved by a reporter's swift action as a roadside bomb explodes. When the man later vanishes, Stone is asked to find him. The trail leads from Iraq to Bermuda, London and Kabul, the dark and brutal city where governments, terrorism and big business inexorably collide. Caught in the crossfire, his nightmare is only just beginning, for the hunter has suddenly become the hunted. . .
