The rain hammered the cobblestones as the carriage rattled tonight. Inside, the manor's grand hall echoed with hushed whispers softly. A candle flickered, revealing a portrait of a stern lady. The clock struck midnight, and the lights suddenly went out. A scream shattered silence, echoing through the marble corridors deeply. Detective Marlowe arrived, notebook in hand, eyes narrowed silently still.
