Vineyard wedding bells are about to chime for ex-Boston cop-turned-island-fisherman J.W. Jackson and his lady Zee Madieras. And Zee's Automatic Teller tells them rather substantial "present" has been deposited in the bride-to-be's account: one hundred thousand unexplained dollars.

The bank screams, "computer glitch"! And sure enough, two days later, the windfall has flown. But, coincidentally, the college student lying dead in J.W.'s driveway'a young woman done in by a dose of locally grown poison'recently withdrew a hundred grand from her own account. And now, before exchanging vows with his love, J.W. must first match wits with a murderer who may be gearing up to kill again.
