Model response

The storm began at midnight, splitting the roof, and a scream escaped from the locked study quietly behind the door. Inspector Vale entered, found chalk outlines, and asked the trembling servants if anyone had touched the body that night here. On the desk, a letter trembled beside the teacup, its ink still wet under the pale lamp in the hall. Then the mirror shattered, revealing a black glove, and the clock stopped at the exact minute of murder that night.
