Model response

The rain fell without mercy. Detective Shaw arrived quite late. A body lay perfectly still. Blood stained the white carpet. No one heard the screams. Windows remained completely shut tight. Shaw knelt beside the victim. The face showed pure terror. One shoe was found missing. Neighbors claimed they saw nothing. Shaw pulled out his notepad. Something felt deeply wrong here. The clock read half past. A glass sat nearly full. This case would haunt him.
