Rain hammered the coastal road all night, but nobody noticed fresh footprints leading toward the dark lighthouse door that morning. Detective Marlow arrived at dawn, carrying a notebook, while gulls circled silently above the lighthouse's rusted lantern room that day. The victim lay motionless beside an overturned chair, one hand still gripping a cracked photograph of a younger smiling woman. The keeper claimed he had heard strange voices whispering through the radio shortly before midnight, just before everything went silent. Marlow searched the tower stairs slowly, finding a torn glove, a brass key, and traces of muddy bootprints everywhere nearby. When the coroner lifted the photograph, Marlow recognized the woman staring back from the faded picture as his missing sister.
