Model response

Shadows danced wildly within the grand, dimly lit ballroom.
Sir Reginald Hamilton lay lifeless near the ornate fireplace hearth.
The butler stumbled back, his eyes wide with utter horror.
A single, ornate dagger gleamed beside his pale, still hand.
Crimson stained the rich velvet carpet beneath his head.
No other guests were present in the chillingly silent room.
Detective Harding surveyed the scene of the tragic demise.
Something felt disturbingly wrong about this fatal, sudden end.
