Model response

Rain stitched silver lines across the harbor as Detective Mara Vale stepped from her car, already sensing trouble tonight ahead.

The mansion loomed above the cliffs, its windows dark except for one upstairs lamp burning like a warning flare tonight.

Inside, the host lay sprawled beside the fireplace, a crystal tumbler near his hand, blood pooling into lacework patterns slowly.

Mara noticed three guests waiting in the parlor, each silent, each polished, each hiding fear behind practiced expressions tonight too.

Then the clock stopped, and from the hallway came footsteps that belonged to someone who thought the killing unfinished still.
