As an aspiring F.B.I. man, cocky young Ayer looked to most like a washout. He was accordingly banished to Cincinnati, where he was presumably out of harm's way. There to the surprise of all he did some extremely creditable work in such varied fields as bank robbery, murder, and suspected Nazi sympathies. Ayer, restored to the good graces of his superiors, was next assigned to a European post and the investigation of cases of espionage and treason. Nothing very exciting happened to him abroad, but he did visit the big cities, come in contact with Eisenhower, and develop a fund of anecdotes and impressions. After the war, Ayer became ""security officer"" (actually, a tough legal and liaison job) with the American Mission for Aid to Greece- a lengthy prologue which is easily the best thing in the book. The narrative, taking it all in all, is candid and candied, full of supercharged attacks on communism. There are a number of tense moments, though as a whole it doesn't live up to the layman's conception of the job.
