Heavy rain lashed against the tall windows of the manor. A sharp scream pierced the quiet halls of Blackwood estate. Lord Sterling lay face down upon the ornate Persian rug. Crimson blood seeped slowly into the expensive antique wool fibers. A silver letter opener was buried deep in his back. Detective Vance stepped carefully through the wide mahogany double doors. Every single window in the dark study was locked tight. Six nervous dinner guests stood frozen in the grand hallway. One of them was definitely a cold and ruthless killer.
