The old lighthouse stood silent against the gray morning sky. Detective Mara Vance stepped from her car onto wet gravel. Two officers waited at the door, faces pale and grim. The keeper lay sprawled across the tower's cold stone floor. A brass telescope rested beside his outstretched, lifeless right hand. No blood anywhere, yet his eyes were frozen wide open. Something about the room felt wrong in indescribable, quiet ways. The lantern above them still turned, casting shadows across everything. "He was the friendliest man alive," the deputy whispered softly. Mara knelt beside the body, noting the smell of almonds. Poison, she thought, but nothing about this felt that simple. The keeper's logbook lay open on the desk nearby, untouched. The final entry read simply: "They know about the light." Outside, the tide withdrew, revealing something half-buried in the sand. Mara stepped toward the window, her instincts already sounding alarms.
