Cold rain hammered the wet cobblestones outside Blackwood Manor while Detective Marlowe stepped through the heavy unlocked front door alone. Deep inside the vast grand foyer one candle flickered weakly beside the still body of Lord Ashworth lying face down. A silver letter opener protruded from his back while the heavy oak study door behind him stood slightly ajar tonight. Marlowe knelt carefully and noticed the victim's cold left hand clutched a torn scrap of cream stationery bearing one word. The single word was traitor, written in hurried black ink that had already begun to smear beneath the falling rain. Somewhere upstairs a loose floorboard creaked once, and Marlowe rose slowly with one hand already resting upon his holstered revolver.
