Traitors in the Tyrol

Almost immediately following 'Assignment in the Alps', the Wallace Boys and Karl-Franz head up into a remote area of the little Alpine kingdom for a bit of R&R. Little do they realize they are heading for trouble - in the form of a secret department of the CIA, America's Central Intelligence Agency. It is this department that has been clandestinely funding the attempted coup in the kingdom - and now they want their money back! The three boys somehow get in the way! And the CIA is hot on their heels, not to mention Rupert of Hentzau, Duke Michael and their oafish henchmen, Bersonin and Krafstein.
