After this, Nell made it a practice to look at Fiona from time to time. 
She noticed that Fiona never stopped writing, but she was not paying attention 
to the old books. As she finished each page, she folded it up and placed it in 
her reticule. From time to time, she would stop and stare dreamily out the 
window for a few minutes, and then resume; or she might place both hands over 
her face and rock back and forth silently in her chair for a while before 
giving herself over to a long burst of ardent writing that might cover several 
pages in as many minutes.
