Cold rain lashed violently against the tall glass windows while Detective Arthur Pendelton stared grimly at the dead politician below. Crimson blood pooled slowly across the expensive Persian rug, staining his pristine white silk shirt with dark, terrifying scarlet finality. Strangely, every single heavy oak door throughout the sprawling mansion remained securely bolted from within, showing zero obvious forced entry. Beside his lifeless left hand lay an antique silver dagger, gleaming wickedly beneath the flickering light of seven tallow candles. Downstairs, five nervous dinner guests waited silently inside the parlor, each hiding desperate secrets behind masks of polite, aristocratic grief. Arthur adjusted his damp trench coat, realizing immediately that the clever killer was still hiding somewhere inside this locked house.
