The brass key turned slowly inside the rusted lock, granting access to the very old abandoned manor on the hill. Cold air rushed past the detective as he stepped across the threshold into the shadowy entrance hall, listening very carefully. A single crimson stain marked the polished wooden floor, pointing toward the library where the victim lay completely motionless now. Silver candlesticks stood crooked upon the mantle, casting long and dancing shadows across the faded floral paper covering every wall. He knelt beside the body and noticed a torn letter resting near the stiff and pale fingers of the deceased. The wax seal bore a raven emblem, suggesting that powerful enemies had orchestrated this cruel and carefully planned evening murder.
