Model response

At dawn, bells rang strangely.
Mara found the library door ajar.
One red candle guttered nearby.
The clock had stopped at midnight.
Rain tapped softly against the windows.
A silver key lay beneath the desk.
Someone had locked the garden gate.
Behind her, floorboards creaked once.
Mara turned, holding her breath.
No one stood in the shadows.
Then the telephone began ringing.
