Model response

The rain fell without mercy. Detective Clara surveyed the room. Blood stained the white carpet. A champagne glass lay shattered. Nobody heard the fatal scream. Clara knelt beside the body. The victim wore expensive clothes. His watch had stopped ticking. Someone had planned this carefully. The window stood slightly open. Cold air filled the space. Clara noticed muddy boot prints. They led toward the fireplace. A letter sat partially burned. Tonight would not be simple.
