The heavy iron gates creaked open in the cold rain. Black clouds gathered above the lonely house on the hill. A single light flickered weakly within the dark parlor room. Detective Miller stepped inside and felt a sharp, sudden chill. He saw the body lying across the expensive velvet rug. Blood stained the white lace of her very elegant gown. No signs of forced entry appeared near the front door. Everything in the dusty study remained exactly in its place. Someone had killed the lady before the clock struck twelve.
