Between sunbathing and snorkeling they'll investigate local expatriate Bernhard Kruger, who may be involved in a credit card scam. Things heat up fast. First Frank and Joe's car is run off a cliff into the water. Then, when they try to rent a couple of mopeds with their father's credit card, they're charged with fraud and counterfeiting. With a vicious enemy closing in, Frank and Joe find themselves in some very deep water.

Back Cover Write-Up[2] -- Frank and Joe are soaking up some sun in Bermuda and doing a little sleuthing on the side.

When the Hardys spy on Kruger's villa, one of his thugs spots them. Before they know it, they're being tailed by a black sedan and run off the road into the ocean! This is not the act of an innocent man. Their vacation shot, Frank and Joe resolve to nail Kruger.
