The lighthouse keeper found the admiral dead at midnight precisely. Rain hammered the windows while thunder rolled across the harbour. Detective Marlowe arrived silently, coat dripping, eyes scanning every shadow. A single silver key lay beside the victim's cold hand. No doors were broken, no windows opened, nobody had entered. Marlowe knelt down and noticed mud upon the pristine carpet. The admiral's daughter watched nervously from the darkened hallway beyond. Her trembling fingers clutched a letter stained with fresh ink. "He knew this would happen," she whispered, tears falling freely. Outside, somebody laughed softly, then vanished into the stormy night.
