Wren, thankfully, had not seen the interaction between Eve and John. If she had, she wouldn't have been smiling when Eve came through the door. Instead, she was fixing her hair in the mirror, watching the door in the reflection.
When Eve entered the bathroom, Wren turned and leaned against the sink and looked at her. The pent-up annoyance was visible, and the kick to the door only served to solidify it. "Did you steal them?" she asked plainly, referring to the books, no judgment in the asking. She assumed Eve was here to gloat over the victory. It didn't occur to her that Eve had the money to move in these circles, simply because she had never seen any indication of it.
