Reviews:
Debra (USA: OR) (2010/06/24): Description: Fenton Hardy is trying to find out who is out to sabotage a new military radar installation. At the same time Frank and Joe are on the trail of a missing college professor. It seems the further the boys travel in following the missing professor, the more suspicious characters they discover. Some people they encounter who appear suspicious may not be, and others who appear to be uninvolved may be. How will the boys learn where the missing professor is located?
During Frank and Joes' investigation they come across a huge complex of caves. While staying in the cavern the boys have their stuff stolen and are threatened. What could be so important that someone would want to chase the Hardy Boys away?
