Midnight rain unexpectedly battered the silent mansion where Detective Blythe arrived after a cryptic phone call announcing sinister events outside. Inside the grand foyer, a shattered chandelier hung precariously above bloodstained marble floors where footprints led mysteriously down dim corridors. A single candle flickered beside an antique mirror reflecting trembling silhouettes that hinted at unseen dangers lurking within cold walls. Suddenly, a distant scream echoed through dusty hallways jolting everyone into icy silence and raising urgent questions about potential motives. Detective Blythe knelt beside a toppled chair, inspecting fresh footprints smeared in crimson while carefully noting each possible ominous detail. A lifeless body lay draped over a velvet sofa, its pale hand pointing accusingly towards a revolver resting on table.
