' "Has Le Carre been in Intelligence?", we were often asked when The Spy Who Came In... started blooming. Te reply is, only to the most trifling extent. If we are asked the same about Ayer when The Man in the Mirror starts blooming the reply will be Yes. In Yankee G-Man (not published in this country) he describes his experiences in the F.B.I.; in a counter-intelligence unit in Europe during and shortly after the war; and finally as Chief Security Officer for General Van Fleet in Greece. His last book, a very personal account of his uncle, General Patton, was published in the States last spring by Messrs. Houghton Mifflin and was a best-seller: it will be published here by Cassell.

Now comes this spy novel.

No more blurbery. Turn to page 9, and read on.'
