The heavy velvet curtains concealed the dark secret that lay beneath the polished floorboards of the ancient, silent manor house. Rain lashed against the tall windows while a single candle flickered weakly upon the mahogany desk in the corner. Detective Miller adjusted his heavy wool coat and stepped slowly into the room where the bitter scent of almonds lingered. He knew that the victim had been betrayed by someone who once called this cold and lonely place their home. A broken glass lay shattered near the velvet armchair where the wealthy old man had met his sudden, violent end.
