The lighthouse beacon went dark at midnight precisely yesterday again. Detective Mara Quinn arrived soaked, clutching a rusted iron key. Inside, Eleanor Vance lay sprawled beneath shattered glass chandelier lifelessly. Her hands clutched empty air, not pearls everyone expected tonight. Someone had cleaned blood, but forgotten muddy footprints outside entirely. The iron key matched no door in this house apparently.
