Where did you get the idea for the e-mails?

I can't remember specifically, but I can say that it was an idea that I'd slowly been working toward all along. I knew I wanted to add some tension to the relationship, and Jeremy's situation (as described in True Believer) seemed the perfect way to do that. I wasn't sure, however, how Jeremy should begin the question whether the baby was his. Did someone new show up in town? Was it a phone call? A letter? In the end, I decided to use an e-mail.
