Heavy rain battered the tall library windows while Detective Miller crouched silently beside the dead politician on the cold floor. A gleaming silver dagger protruded from his chest, pinning a mysterious crimson envelope directly above his still, silent, broken heart. The antique grandfather clock in the shadowy corner had stopped ticking at precisely midnight, marking the exact moment of death. Every single door and window remained securely locked from the inside, leaving the terrified mansion guests with no obvious alibis. Miller slipped on his thin latex gloves and carefully plucked the bloody note, realizing the killer was still hiding nearby.
