Midnight draped over the manor, shadows whispering ominous secrets tonight. A bloodcurdling scream shattered silence, echoing through cold empty hallways. Lord Blackwood lay motionless, eyes frozen in eternal disbelief still. Detective Marlowe entered, rain-soaked coat, mind swirling with motives deeply. He surveyed the scene, noting the broken glass, scattered letters. A silver key rested near the victim, glinting ominously still. Mysterious footprints trailed toward the locked library, vanish at threshold. Whispers claimed the manor held dark secrets, cursed for generations. Marlowe unfolded a worn notebook, each page detailing past tragedies. He whispered to himself, justice will unveil the hidden killer.
