The fog settled thickly over the silent, deserted mansion grounds. Detective Marla stepped cautiously through the creaking, ancient wooden door. A cold draft whispered secrets from shadows in every corner. Blood pooled beneath the shattered vase near the grand staircase. Footsteps echoed suddenly, breaking the eerie, heavy midnight calm. Marla searched for clues, eyes sharp under flickering chandelier light. A single pearl earring lay glinting beside the victim’s hand. Whispers of betrayal filled the room with unseen tension. Outside, the storm raged, trapping everyone within the house walls. The murder mystery had begun, with no one yet speaking.
