Model response

Rain drummed against the windows. Detective Sarah Chen arrived late. The mansion loomed in darkness. A scream had shattered midnight. Now silence filled the halls. Blood pooled beneath the chandelier. The victim wore black silk. Her eyes stared at nothing. Seven guests waited in fear. Each one had a motive. Each one had a secret. The killer stood among them. Sarah removed her wet coat. She studied every nervous face. Someone here would slip up. Murder always left its traces. The game had just begun.
