The evening had been calm, but now, under the flickering lamplight, Mr. Thorne's body lay motionless on the cold floor. A single bullet wound, stark and precise, marred his chest, while a pistol lay discarded on the dusty rug nearby. The detective noted the overturned chair, the shattered window, and the faint smell of gunpowder lingering in the thick air. Outside, the storm raged unabated, but inside, the silence was broken only by the detective's thoughtful sighs and faint creaks. He knew this was no accident; the pieces fit together like a puzzle awaiting final revelation in the dim light.
