The storm raged outside the old stone manor, its fury mirroring the sudden unease settling heavily within its darkened halls. Detective Harding cautiously pushed open the heavy oak door, a chilling draft whispering secrets of a tragedy yet undiscovered. A single, flickering gas lamp cast grotesque shadows across the opulent study, illuminating a scene that would forever haunt his troubled mind. Lord Ashworth lay sprawled upon Persian rugs, his normally stern face now frozen in a rictus of unspeakable, sudden terror. A single, ornate letter opener, usually gracing his mahogany desk, now protruded unnaturally from his chest, disturbingly precise. The air hung thick with the scent of expensive cigar smoke and a metallic tang that spoke unmistakably of freshly spilled blood. A shattered glass lay near his lifeless hand, its fragments glinting like shattered dreams under the dim, oppressive lamplight. No forced entry marred the elaborately carved window, suggesting the killer perhaps belonged to the household or was intimately known here.
