THE END of the summer before, Annette Sotherby, daughter of one of the wealthy summer people on Netaquid Island has been kidnapped under mysterious circumstances and returned under even stranger circumstances. The Netaquidders, who earned a scant livelihood from the sea and from working for the summer people, spent days looking for Annette. Yet once she had been returned, there had been no word of thanks. Instead, the cottagers seemed determined to ignore the islanders.

But that changed when Mr. and Mrs. Truell both had to leave and there was no one to care for Sammy Truell, except the Collettis, the old Italian couple who could not keep up with an active four year old. So Molly Bassett was hired. And it was not long before she began to learn just why things were so tight for islanders. The Kidnapping had had strange consequences she was not supposed to talk about, and the islanders were implicated.

It was up to Molly not only to discover the truth of what had happened the year before, but ultimately to solve a brand new and even more disastrous kidnapping in order to bring the islanders once more into favor with the summer people and give them a chance to earn the money they so desperately needed.
