David Trevellyan, a Royal Navy intelligence operative, takes a late-night walk to his New York City hotel. A huddled shape in an alley catches his eye—a homeless man has been shot to death. Trevellyan steps forward and a cop car arrives. A split second too late, Trevellyan realizes he's been set up. Obliged to clear his name, and with no idea who's a friend and who's a foe, he penetrates deep into a huge international conspiracy. The price of failure will be death, and the reward for success will be redemption, both for himself and the huddled corpse from the alley.
