Model response

The old manor stood dark.
Rain lashed against windows.
Inside, silence felt heavy.
A sudden crash broke peace.
Then a bloodcurdling scream rose.
Footsteps pounded down the hall.
"He's dead!" someone shrieked loud.
Lord Harrington lay on ground.
His eyes stared at ceiling.
A crimson stain spread wide.
Detective Eleanor Vance arrived then.
She surveyed the gruesome sight.
A chilling puzzle awaited her.
The killer remained unknown still.
Who ended his life here?
