Heavy rain hammered the roof while Inspector Graves entered the study to find Lord Blackwood lying dead upon the floor. A single candle flickered on the mantle, casting long shadows that danced around the bloodstain spreading beneath the victim's head. He checked the pulse with trembling fingers, confirming what his dark eyes already feared was undoubtedly true inside the room. The grandfather clock chimed midnight, its mournful tone echoing through the hall as a soft knock sounded at the door. Graves froze, his hand reaching for the service revolver inside his holster against the sudden chill running down his back.
