Model response

The old manor stood silent.
Wind whispered through dead trees.
Detective Thorne's car arrived.
Rain slicked the long drive.
He grabbed his black coat.
Yellow tape barred the door.
Thorne ducked under the plastic.
Footsteps echoed on marble.
The air felt very cold.
A faint smell of blood.
He found the study door.
It stood slightly ajar.
Thorne pushed it open.
Darkness filled the study.
A single lamp lay broken.
Sir Eldred lay on floor.
His gaze fixed on ceiling.
A crimson flower bloomed there.
No signs of violent struggle.
The room seemed undisturbed still.
Death arrived swift and cruel.
This was a professional kill.
