The old manor stood silent beneath a blood-red moon tonight. A scream shattered the quiet and echoed through empty corridors. Detective Harlow arrived and found the butler already quite dead. Blood stained the marble floor near the grand staircase landing. The guests swore nobody could have entered or left unnoticed. Harlow studied their faces and trusted absolutely none of them. Outside, rain began falling hard against the dark library windows.
