Model response

The grand library’s oak doors creaked open under moonlit shadows’ grasp.
Cold wind whispered through shelves, stirring dust from forgotten books’ spines.
A single candle flickered weakly, casting eerie light upon polished mahogany floors.
Footsteps echoed softly as someone moved with deliberate, unsettling precision forward.
Blood pooled darkly beneath the desk where the victim lay motionless.
Glass shattered somewhere distant, but no one dared to investigate.
The air smelled of old parchment mixed with something metallic.
A gloved hand clenched a letter, edges torn and ink smeared.
The clock struck midnight just as the last breath escaped.
Somewhere in the dark, a killer smiled behind a silver mask.
