Model response

Rain hammered against the windows.
Mara Quinn studied the corpse.
Lord Ashford lay face down.
Silver blade pierced his back.
The study door was locked.
Only three people held keys.
Each of them had lied.
Constable Reed noticed the clock.
It had stopped at midnight.
Someone had moved the hands.
Mara knelt beside the victim.
His wedding ring was missing.
Somebody had taken it deliberately.
Reed cleared his throat nervously.
Then the lights went out.
Darkness swallowed the house whole.
Somewhere above, a footstep creaked.
Mara reached for her flashlight.
A scream shattered the silence.
