The library lay silent beneath the ticking clock's cold hands. A body slumped over the mahogany desk, unmoving, still, quiet The fireplace crackled low, casting flickering shadows upon the walls The inspector paused, noting a broken wineglass near the rug No forced entry; a window gaped upstairs slightly through draft The blood on the floor was still wet, dark, fresh Something glittered beneath the chair;a gold cufflink lay there
