The body of the old baron lay on the rug before the roaring fireplace and the cold hearth stone floor. The shattered crystal glass sparkled near the marble leg of the antique settee by the tall window panes beyond manor. A faint scent of rose perfume mingled with the metallic smell of fresh spilled blood on the Persian rug below. The clock on the marble mantelpiece ticked loudly, a lonely sound in the silent darkened room now for the dead. A single playing card, the Ace of Spades, lay pinned to the dead man's chest with a silver letter pin. No sign of struggle marred the scene except for the overturned bronze lamp upon the floor near the door frame. The heavy oak door creaked open slowly, revealing a solitary figure waiting in the shadows within the library room now. Detective Inspector Harris stepped into the light and studied the gruesome murder scene with a steady and low calm breath.
