I love the Lord John novels and novellas. It was interesting to me how you wrote his character while he was recovering from his battle injury--he was not himself, yet still clearly the same character. You did that so well. My question is, (spoiler) why did Percy betray him? It just seemed like such a stupid thing to do! Was he just stupid?
Well, Percy was deeply insecure--I mean, consider his background. And he was used to being sexually taken by anyone who wanted him; he'd been a prostitute. So I imagine he just didn't have the gumption to resist Weber's threat of blackmail; the sex itself would have seemed inconsequential to him.
