Existing comment: The First Spymaster:
Chinese general Sun Tzu wrote The Art of War -- the earliest-known text on warfare and espionage -- around 400 BC. In it, he devoted an entire chapter to spying, stressing the importance of intelligence and counterintelligence.
His classic work has stood the test of time. It's still required reading in military services around the world -- business leaders apply his strategies and tactics to gain the edge against their competitors.
