The grand library fell silent as the clock struck midnight. Shadows stretched long across the polished mahogany floor. A single candle flickered, casting eerie, dancing light. The old professor lay sprawled near the ancient fireplace. Blood pooled darkly beneath his motionless, outstretched hand. His glasses were shattered, lenses scattered like broken stars. A torn page fluttered from his stiff, lifeless fingers. The title read "The Secret of the Black Rose." Footsteps echoed faintly down the empty, dimly lit hallway. Someone had silenced him before he could speak.
