On a sizzling-hot September day, Eva Knox's ex-boyfriend, Dudley Dexter Codman the Third, along with a bunch of his corporate cronies from Boston, arrive at Eva's family's guest inn and olive farm, Knox Plantation. Maps and binoculars in hand, the New Englanders claim they're on a bird-watching holiday. Only, Eva knows that her ex doesn't know the first thing about birds. Nor does he care.
Eva can't fathom why he'd show up after all these years in her off-the-beaten-path hometown--nearly 1,200 miles from Boston. When Dudley's body is found drowned in the pond, Eva starts fishing for answers. But she doesn't have much time after authorities determine that her ex was poisoned by one of Eva's family's olive oils. She'll have to find the real killer before her family is caught for murder.
