It's spring. Jack, Max, Patti and Courtney have just returned from a not-so-relaxing vacation in Southern California only to find that Leo, Ralph and Paulie have returned after several years away, fearful that they are being pursued by a killer. Gladys, the ever-vigilant bird watcher, tells Jack that she has seen some suspicious activity in her marshes and Jack learns that Tom’s life has been threatened.


When Jack sees a beautiful sailboat arrive in Rye Harbor, he greets the skipper, who is not only unfriendly, but disappears soon after taking Jack’s advice to leave his boat at the Wentworth Marina. Then, with Sylvie’s unexpected arrival, and the appearance of a magnificent mega-yacht, named the Jenny D, at the Marina, this convergence of events turns deadly.
