Model response

Rain tapped softly on windows.  
Detective Vale entered through silence.  
Everyone watched the grandfather clock.  
Its hands had stopped at midnight.  
Beneath it, Lord Ashford lay motionless.  
Blood darkened his white dinner jacket.  
No weapon rested beside him.  
His guests stood frozen nearby.  
Only Clara carried a candle.  
She trembled beside the staircase.  
Vale studied every frightened face.  
“Who discovered him?” he asked.  
Nobody answered him immediately.  
Then the clock began chiming.  
Each bell sounded like a warning.
