Summary
Analysis
Juliet writes Dawsey about her most recent letter from Adelaide, in which Adelaide incredulously recounted going to find Dawsey to help her distribute the parish magazine and found him reading Charles Lamb in the hay. Juliet asks why Adelaide is so horrible. She says she enjoys the image of Dawsey reading in the hay, as she used to do the same thing as a child.
Now that Juliet has heard about how and where Dawsey reads, she's able to see that the two of them are very alike and share even more interests. With this, they continue to develop their relationship through their shared love of reading.

Susan writes to Sidney and begs him to come home: Charlie Stephens has started coming into the office, but she believes the effort will kill him. In other news, various employees are running amok and she advises that Sidney fire Miss Tilley. She also mentions that she's seen Juliet and Mark out on a date. It looked very romantic and though Juliet invited Susan to join them, Mark looked very upset that she interrupted.
Susan's assessment of Mark is telling: he doesn't want to have to acknowledge that Juliet is her own person with her own friends. This reinforces that Mark's intentions are to eventually control Juliet, not treat her as an equal partner.
