"A thrilling account of Counter-Intelligence in action, by the man Eisenhower called "the greatest living authority on security" - and who was personally responsible for the execution of seven spies. This is the true story of his adventures during World War II - first in England, where he was given the job of screening the thousands of refugees that poured into that country after the fall of France, separating the well-meaning unfortunates from those who tried to sneak in as Nazi spies. Later on the Continent, he served as chief of the Dutch Counter-Intelligence organization, attached to SHAEF. Each tale reveals a different aspect of successful spy-catching."
