Rain hammered the old lighthouse windows all night relentlessly again. Detective Mara Quinn arrived before dawn, coffee steaming weakly still. Inside, the keeper lay sprawled beside shattered brass instruments silently. Blood pooled darkly beneath his head, already cold congealing slowly. Mara noticed footprints leading toward the locked storm door outside. No wind could have sealed that door from inside alone. Someone had left the lighthouse, or never left at all.
