Model response

Detective Mara Quinn arrived precisely at midnight, utterly alone tonight. The lighthouse door hung open, creaking in salty wind relentlessly. Inside, Eleanor Vance lay sprawled across cold marble floor lifelessly. Her silk dress remained immaculate despite obvious violent struggle nearby. No footprints marked the dusty stairs leading upward silently tonight. Quinn noticed fresh coffee steaming beside the dead woman patiently. Someone else had been waiting inside moments before murder arrived.
