At midnight, the lighthouse keeper's daughter found a dead man sitting upright at their kitchen table, wearing her father's coat. Rain hammered the windows while the lighthouse beam swept across his face, revealing eyes sewn shut with bright blue thread. On the table beside him lay three untouched teacups, a silver key, and a photograph of her mother's forgotten wedding. Clara recognized everyone in the photograph except the bride, whose face had been carefully scratched away with a sharpened instrument. Her father had disappeared before supper, leaving only instructions to keep the light burning and never answer the western door. Now someone knocked there softly three times, then waited as if certain she would forget everything she had been told. The dead man's pocket watch began chiming, although its hands were missing, and Clara knew its melody from her childhood. Outside, beneath the knocking, a familiar voice whispered her name and asked whether she had finally found their missing guest.
