Model response

A fierce storm raged outside, battering the dark windows of the house.  
Lightning flashed, illuminating the study where shadows danced on walls.  
Sir Reginald slumped in his chair, eyes fixed in death.  
A pool of blood spread across the Persian rug below.  
The poker from the fireplace lay stained beside his hand.  
Footsteps echoed in the hall as the butler approached slowly.  
He gasped, dropping the tray of tea onto the floor.  
Inspector Blackwood arrived soon after, surveying the grim scene carefully.  
Who could have entered this locked room without a trace?
