Midnight storms battered the isolated Blackwood Manor, its shutters rattling as thunder roared across the desolate moor in cold darkness. Detective Harriet Vance stepped through the creaking front door, her lantern trembling, as the scent of iron permeated the foyer. On the polished parquet, a lifeless businessman lay, his chest punctured, a silver dagger clutched tightly within his rigid hand. Near his fingers, a crumpled note read, 'The reckoning begins at midnight, and the guilty shall forever wander these halls.' Detective Vance knelt, her eyes narrowing, as rain drummed against the windows, whispering secrets of past sins and unseen perpetrators.
