In the winter of 1939, Shanghai was an isolated island. Lu Zheng, owner of the Zhengji Foreign Trading Company in the French Concession, is a smooth operator in public and a clandestine agent for the Military Statistics Bureau, codename "Gray Falcon," behind the scenes. Between assassinations, espionage, and maneuvering between the 76th and the Special Higher Police, each deadly mission leaves his body tempered by a night of burning fever. His resistance to blows, reflexes, pain tolerance, and recovery all push him toward the limits of human endurance. The game is not over, and a scar marks his wrist. When his younger sister becomes a hostage and his opponent is Major Inoue, a man who loves chess, he must make his final move between "serving his country" and "protecting his family."
