Model response

Rain stitched silver threads across the manor's blackened windows tonight.

Inside, the candles trembled, as if fearing what they revealed.

Detective Mara Vale paused beside the staircase, listening to silence.

Silence shattered when a scream rang from upstairs, startling everyone.

Mara climbed, hand brushing the banister slick with fresh blood.

At the landing, a locked study door stood ajar, impossibly.

A corpse lay beyond it, facedown, wearing the host's ring.

Mara smiled grimly, because the murderer had already left clues.
