Rain hammered the old lighthouse windows without any mercy tonight. Detective Mara Ellis arrived precisely at midnight, coat soaked through. Inside, the keeper lay face down beside shattered brass lantern. Blood pooled darkly across cold stone, mixing with seawater puddles. Only three guests remained upstairs, each claiming complete innocent silence. Mara noticed the clock stopped at eleven forty five sharp. Someone had locked the tower door from the inside somehow.
