What would the world think if a handsome naval hero who had access to his government's secrets suddenly disappeared in mysterious circumstances - especially if some of his files appeared to be missing and a cryptic farewell wire was found? Commander Colin Easton meets an old comrade and is introduced to his friend's wife, Isobel. The two soon start an affair and hatch a money-making plot. He takes himself off to Megstone, one of the Farne islands off the coast of Northumberland, so that he is branded a traitor by the Press, in the hope that he can sue for libel. Being 'marooned' on this small deserted island with his 'rescue' assured is not so bad . . . but he didn't count on another girl getting enmeshed in the plot, and Colin soon finds that two women is too many.
