Detective Mara Keene arrived at the lighthouse after midnight exactly. Rain hammered shutters while wind screamed like wounded gulls outside. The victim lay sprawled beneath the shattered Fresnel lens silently. Blood mixed with seawater, pooling around polished brass fittings ominously. Mara recognized him instantly: old Tom Whitaker, beloved lighthouse keeper. Someone had extinguished his light forever, deliberately and cruelly tonight. Footprints led toward the cliffs, then vanished into darkness completely.
