At the Lighthouse Library, Lucy and her colleagues have assembled an exhibit of library artifacts showing how libraries have changed over the years. After the opening night reception, some of the women take a walk down the boardwalk to the pier, using flashlights to illuminate the dark path, but what's scarier than the dark is finding the former director of the Lighthouse Library floating lifeless in the water. Lucy finds herself in deep water as she rocks the boat, questioning several suspects. But she'll have to batten down the hatches and fast before she's left right in the killer's crosshairs.
