Model response

The grand library stood silent beneath flickering candlelight this evening. Detective Morrison examined the body sprawled across antique Persian carpets. Lord Pemberton lay motionless, a crystal paperweight beside his head. Blood pooled slowly around expensive leather-bound volumes scattered everywhere nearby. The butler trembled nervously while explaining he discovered the scene. Morrison noticed the victim's fingers clutched a torn photograph tightly. Three suspects waited anxiously in the drawing room downstairs below. Thunder crashed outside as rain pelted the mansion's tall windows. The detective knew this would be a very long night.
