Rain fell on dead grass. Dark shadows hid the porch. The front door stood open. Detective Vance stepped inside cautiously. Dust danced in moonlight beams. A grandfather clock ticked loudly. Stale perfume lingered heavily here. Red blood stained Persian rugs. Lord Blackwood lay face down. Glass shattered near his hand. Someone had searched the study. Vance knelt beside the body. Ice cold skin touched fingertips. Death came quite very suddenly. No pulse beat beneath fingers. A silver dagger glistened nearby. Footsteps creaked upstairs right now. Someone was still hiding here. Vance drew his service weapon. Shadows shifted down the hall.
