There’s more than one reason the new West Tisbury police chief officially made ninety-two-year-old Victoria Trumbull her deputy. For one thing, Victoria knows just about everything about everyone in Martha’s Vineyard, not to mention their ancestors. She may be ninety-two, but she is as sharp and as sharp-eyed as the proverbial tack. So when Victoria is the only one who spots something amiss among the gravestones of the West Tisbury cemetery, it’s no surprise that the police chief listens. Something is indeed amiss. First comes a request by presumed relatives in the Midwest to disinter a coffin for reburying elsewhere. Then things go wrong from there. When, as a last measure, the coffin is found, dug up, and opened, it does not contain the expected body. Then the coffin itself disappears.
