Height of Danger is the 56th book in the The Hardy Boys Casefiles series.
Frank and Joe are working security at the World Snowboarding Championships in Austria, and they're learning fast that the Alps can be as dangerous as they are beautiful -- the perfect setting for sabotage. Ken Gibson is the number-one competitor and the number-one target. Reason: He's been leading a secret life!
The race is on, and the stakes are as steep as they get. Frank and Joe discover that both the Network and an underworld gang have gotten into the game. The Hardys are standing on top of a mountain of trouble -- and it's about to explode under their feet!
