Plot summary

A series of adventures begins for the Hardy Boys and their friends Chet and Biff after they sail their ice boat, the "Sea Gull", to the desolate and inhospitable Cabin Island. They had been invited to spend Christmas vacation there at the invitation of its owner, Elroy Jefferson, as a reward for recovering Jefferson's car in The Shore Road Mystery. Once they arrive on the island, they encounter a mystery with international connections.

As the boys try to enjoy themselves, someone seems determined to spoil their fun. First, two high school dropouts vandalize the loaded ice boat, delaying their departure for Cabin Island by a few hours. Once on the island, a ghost-like hooting leads to an innocent and humorous discovery. All their groceries are stolen, and so Frank and Joe head for the coast to purchase new supplies, but not long after, they find the original stock buried in snow.

Strangers fleetingly appear on the island, and the nephew of a former servant of Jefferson is looking for something at the fireplace. Finally, a foreign dignitary reveals that he is seeking a coin that belongs to his nation's ruler, and had been waylaid by the nephew who was pretending to be Jefferson's representative.
