Model response

The grand clock struck midnight as rain lashed against windows.
Dark shadows stretched across the library’s oak-paneled, book-lined walls silently.
A single candle flickered weakly, casting eerie shapes upon ceiling beams.
Footsteps echoed softly down the hallway, pausing just outside doors.
The butler clenched his trembling hands around a silver-plated letter opener.
Whispers slithered through cracks, though no living soul remained nearby.
Blood dripped slowly from the chandelier’s edge onto Persian rug patterns.
Glass shattered somewhere distant, followed by a muffled, choked scream.
The detective adjusted his gloves while studying the body’s unnatural position.
Somewhere in this house, a killer waited with cold patience.
