<p>Life on the Vineyard is good-maybe just <I>too</I> good--for ex-Boston cop J.W. Jackson this August. The bluefish are running early, and there's plenty of quality fishing time to be spent with his new baby son Joshua. But an idyllic summer hits a snag when a movie scout from a glamorous land called "Hollywood" invades the beaches--and takes a liking not only to the island locale, but to Jackson's lovely lady Zee as well. Worse still, a longtime nemesis turns up murdered just one day after he and J.W. come to blows, and Jackson is considered by nearly everyone, up-island and down, to be the most likely suspect. And if he hopes to spend the remainder of this season--as well as many others to come--enjoying simple family pleasures and fine, fresh seafood outside of a prison cell, J.W. will have to cast his line out and hook the real killer.<p>
