Vineyard stalker : a Martha's Vineyard mystery / Philip R. Craig.

Enhanced descriptions from Syndetics:

J. W. Jackson, the ex-Boston cop turned fisherman, cook, and jack-of-all-trades, delves deep into the mysterious depths of his beloved Vineyard in author Philip Craig's most compelling caper yet. With his wife, Zee, and two kids visiting relatives in "America," J.W. is alone and quickly tiring of his temporary bachelor status. A request from Carole Cohen comes as a blessed diversion. Carole wants J.W. to find the person who's stalking her brother, Roland. Known locally as "The Monk" for his reclusive ways, Roland lives on a beautiful piece of Vineyard real estate that he co-owns with his cousin Sally Oliver. A number of people, including Sally, would do almost anything to convince Roland to sell his valuable property. But does that include violence? J.W. is happy to take on what looks like a short and easy assignment, though he soon realizes that Roland may lead a more complicated life than his austere living arrangements suggest. And when a body turns up near Roland's land, what seemed like a property dispute takes a detour into murder -- with J.W. in the midst of the action once again. Featuring a rich mix of money, lust, pride, and jealousy, spiced with a little poignant regret, "Vineyard Stalker" is a page-turning and deftly plotted addition to this popular and engaging series in which Martha's Vineyard itself is always the star.
