Model response

Rain hammered the manor windows as midnight silenced every clock.

Inspector Vale arrived carrying mud, suspicion, and a sealed letter.

Inside, Lord Harrow lay beneath his own smiling library portrait.

His throat bore one neat wound, but no weapon nearby.

Seven guests waited nearby, each claiming they heard nothing whatsoever.

Then the dead man's pocket watch began ticking backward softly.

Vale opened the letter and found his own obituary inside.

Upstairs, a floorboard creaked beneath an unseen, slowly departing footstep.
