The story of modern espionage, based on a journalist's access to files of many European nations. He covers more territory and includes more unfamiliar data than either the Turrou or the Rowan books. They were confined chiefly to underground Nazi activity in the Americas, while Gollumb covers the whole field of European and American espionage. Not a story of glamorous individual feats, but of organized mass action. The Gestapo has three main branches, -- the termites or groundwork men; the saboteurs, the Harbor Service. In Spain 10,000 spies have paved the way for Franco; in France, the Croix de Feu has done its job; in Austria, Czechoslovaka, Rumania, the work has made grave inroads. Russia has its corps of White Russian and Japanese spies to combat. The U. S. and South America have theirs. A number of fascinating human interest stories. Of its kind, good reading; journalese with an authentic note.
