Model response

The library was deathly still.
Rain lashed against the windows.
Detective Miles surveyed the scene.
Lord Blackwood was quite dead.
He slumped in his armchair.
A book lay open wide.
Its pages were stained crimson.
A letter opener jutted out.
It was plunged into him.
His eyes stared at nothing.
The old clock had stopped.
Now the real work began.
