Detective Mara Quinn arrived at the old lighthouse past midnight. Yellow police tape fluttered wildly against the fierce coastal wind. Inside, the wealthy publisher lay face down on marble floor. A single shattered wineglass glistened beside his outstretched right hand. Everyone at the dinner party claimed absolute shocked innocence tonight. Mara noticed fresh muddy footprints leading toward the locked cellar. Only one guest had left damp traces upon polished stairs.
