Cheyney does an excellent job of conveying the world of spying, with all its twists and double crosses. No one is what he seems, and everyone knows that; but no one is sure just what anyone else really is. Quayle tells his people no more than they need to know.
"Readers of John Le Carre and William Haggard would recognize Cheyney’s world at once." —mysteryfile.com.
