Rain lashed against the tall stained glass windows of the silent library, washing away the blood dripping down the door. Lord Reginald sat slouched inside his favorite leather armchair with a heavy brass letter opener buried deep within his chest. The smell of bitter almonds lingered softly around his motionless body, mingling with the rich scent of expensive tobacco smoke. Outside, a sharp flash of blue lightning illuminated the shadowy room, casting long dancing ghosts across the mahogany bookshelves. Detective Miller stepped over the ornate velvet rug carefully, his dark eyes taking in every single detail of violence. He pulled a silver pocket watch from his damp coat, noting the exact time that another murder had occurred. Someone in this isolated country manor was a ruthless killer, and nobody would be allowed to leave until dawn.
