One Of The Better Paperbacks
Published by Thriftbooks.com User , 23 years ago
While in Germany, Frank and Joe investigate a case of sabotage on an inventor's mini-submarine and the theft of valuable medieval paintings which had been lost after being hidden during World War II. An interesting story with lots of action; the book kept me interested from beginning to end. My only complaint is that none of the Hardy's friends or family were included.
