Mystery Writers of America Presents:

A suspenseful novel of a seaside vacation turned deadly.

Fourteen might seem a little young for a full-time mother's helper, but Mary Shelburne wasn't worried. Prim and responsible Cinni was the best girl Mary interviewed. With two small children and another on the way, Mary needed help that summer at their rented beach house on the tip of Long Island. Her husband Gavin could join them only on weekends.

By the time summer arrives, Cinni has changed. Gone are the owlish glasses and the dumpy figure. Cinni is indeed mature, but not in a way Mary would have suspected. At first Mary doubts her own sanity. Who would believe that such a polite, quiet girl could be a threat-until it's too late? Eaten by envy, Cinni is determined to take over Mary's life and will stop at nothing, even murder. By the time Mary understands this, Cinni has the upper hand. The whole Shelburne family is pulled into a web of vicious terror.
