Dark rain fell silently. Wind whispered through bare trees. A door creaked open. Footsteps echoed on stone. She found him lying. Blood pooled near temple. Clock stopped at midnight. Knife gleamed beside cold hand. Light flickered, then died. Note read: "You’re next." Thunder crashed overhead violently. Footsteps retreated quietly into shadows. Dawn revealed no clues. Only silence remained chillingly.
