Detective Novels is Alan Hind's literary specialty. He is a master at his craft and skillfully satisfies the literary tastes of the mass American reader. These tastes are not known to be particularly subtle. In accordance with this, the artistic side of the work of Alan Hind does not differ in height. We, however, are least interested in this side. The value of the book offered to the Soviet reader is not in its literary and artistic merits, but in its facts. The Soviet reader can treat the actual side of the book with full confidence. The author did not invent anything. He borrowed all his material from the documents of the judicial investigation in the case of German spies in the United States.
