Outside, the gulls cried a mournful chorus against the steady roar of the Atlantic, their sound muffled by the thick, salty air. He remembered a story from his childhood, about a ship that had mistaken a particularly bright star for its light and met disaster on the jagged reefs below. Tonight, the sea was a canvas of inky black, disturbed only by whitecaps that seemed to grin menacingly in the sparse illumination, a perfect, lonely night for a man who preferred the company of waves and silence."
