The castle was large, and she was lost, but she hadn't noticed that
yet.  She was following a sound through the corridors.  As she drew

The sound came from one of the deserted classrooms which looked out
over the courtyard.  There was a blonde girl sitting on the sill of
one of the Victorian sash windows, looking out, tears streaming down
her face. 

Lily hesitated momentarily, then rushed over and flung her arms around
the girl, who collapsed into her embrace. 

"Poor dear, what's the matter?"
