Model response

The body lay face down. Blood pooled on cold marble. Detective Shaw entered the room. Rain tapped against the windows. Nobody had heard any scream. The mansion felt eerily silent. A broken glass caught light. Shaw knelt beside the corpse. The victim wore expensive silk. Her eyes stared at nothing. Someone locked the front door. All five guests remained inside. Each one had a motive. Shaw pulled out his notebook. Tonight would be very long.
