The heavy oak door swung open to reveal the lifeless body of Lord Blackwood lying on the cold marble floor. A heavy silver candlestick rested quietly beside his ruined head, stained with dark crimson blood that pooled around his shoulders. Detective Arthur Vance stepped carefully into the dim room, his sharp eyes scanning for any clues left by the killer. He noticed an empty glass of expensive brandy resting upon the desk next to an unopened letter sealed with wax. A sudden cold draft from the open window extinguished the remaining candles, plunging the entire study into absolute pitch darkness. Someone was definitely still hiding inside the house, waiting patiently for the perfect moment to strike the detective down next.
