The storm had knocked out the power again, leaving the old lighthouse keeper's remote cottage in complete darkness that night. Margaret found him slumped over his mahogany desk, his cold stiff fingers still clutching a half-finished letter to somebody unknown. A single candle flickered beside the body, casting long dancing shadows across the faded wallpaper of his cramped little study. She reached for the old telephone with trembling hands, knowing that this single call would change everything she ever knew. Outside, the waves crashed violently against the rocky shore with fury, as though the sea itself demanded swift justice now. The letter mentioned a name she recognized from long ago, a name that instantly made her own blood run cold. Detective Inspector Marsh would arrive within the hour, and Margaret knew she had to carefully preserve the entire crime scene. But the letter was already folded safely in her pocket, its contents burning a hole through her thick woolen coat. Some secrets, she thought, were truly worth killing for, and this one had already claimed its very first innocent victim. The storm raged on through the darkness, hiding the killer's tracks and keeping the sleeping village below still blissfully unaware.
