Buyers of this book will read it with remembrances and pleasure. Like most field biologists, I have “been there and done that” but failed to put it into words. Paul Freed has accomplished our task for us in a very eloquent manner. Those of us who have suffered hardships chasing critters in the pursuit of knowledge, or who have a flair for photography of wild creatures, have empathy for Paul. Who among field biologists has not contracted beefworms, dysentery, and a sundry of diseases, both tropical and nontropical, or suffered insect bites, spider bites, snake bites, vehicle breakdowns, floods, broiling sun, things stolen, bribes, and export (and import) permit problems?

It was nearly midnight on June 13, 1942. The United States had entered World War II some six months earlier, after the bombing of Pearl Harbor. The nation’s leading law enforcement agency, the Federal Bureau of Investigation (FBI), was aware that spies from Japan, Germany, or Italy—America’s enemies in World War II— might try to bring the confl ict to American soil. A list of Japanese, German, and Italian aliens living in the United States had been compiled. The FBI’s director, J. Edgar Hoover, ordered FBI agents to review telegraph and cable messages to certain countries before they were sent and to read mail being sent to and from the German and Japanese embassies. Security was increased at defense plants and important industrial sites.
