Everybody knows that spies wear white dinner jackets, drive sports cars, like their drinks shaken not stirred and carry electric saws disguised as watches. Or do they? Certainly, some real spies are sophisticated members of the diplomatic service, but most are ordinary people from all walks of life. Written by Richard Platt, author of the best-selling “Cross-sections! Man-of-War” and “Eyewitness Pirate,” Spy is a unique introduction to the dangerous lives of those who exist in the shadowy world of espionage. It’s 64 pages, hardcover.
