Model response

Rain polished the windows when Inspector Vale entered Blackthorn Manor. Everyone waited silently, except the grandfather clock ticking upstairs. Lady Blackthorn lay beneath her portrait, clutching white heather. No doors stood open, and every window remained latched. Yet muddy footprints crossed the carpet, ending beside her. Vale counted six guests, but found seven untouched teacups. Then the grandfather clock stopped, revealing someone breathing upstairs.
