The ornate grandfather clock struck midnight precisely as the weary detective discovered the gruesome body in the dark, silent library. A single silver dagger protruded from his chest, its jeweled handle gleaming under the room's sole flickering, dusty chandelier light. Colonel Mustard lay perfectly still, his normally ruddy face now a truly unsettling waxy shade of very pale grayish blue. A shattered crystal glass rested near his outstretched hand, its contents seeping into the expensive Persian rug beneath them both. The detective noted the locked library windows and the single heavy door which also remained firmly locked from the inside. Yet the colonel was quite obviously murdered, a fact which presented an absolutely impossible and utterly perplexing locked-room puzzle indeed. Outside the storm continued to rage, mirroring the detective's own internal turmoil as he surveyed this very grim scene now.
