Sam Fisher- Knife Fight

  For a long five seconds nothing moved; then the man appeared, stepping cautiously.

  Fisher would never know what had prompted the move--peripheral vision, intuition, something else--but the man suddenly spun around and lunged toward him, a knife in his hand. Fisher caught the man's wrist with his left hand and twisted hard while sweeping the ankle with his foot. As the man fell, Fisher stepped behind him, grabbed the man's chin, and lashed out with the Sykes. The dagger plunged into the hollow beside the man's collarbone, instantly severing the carotid artery, the subclavian, and the jugular. The man gasped, jerked once, then went still. Fisher eased him to the floor and swung the door shut.
