The old lighthouse had not been used for years. Margaret found the body just before the sun rose. Blood stained the wooden floorboards near the spiral staircase. She screamed but the howling wind swallowed her voice. A single candle flickered beside the cold dead man. His eyes were open and staring at the ceiling. Margaret did not recognize the expensive suit he wore. She fumbled desperately for her phone with trembling hands. The beam of light swept slowly across the room. Someone else had been here very recently, she knew.
