I've heard from various sources (with thanks) that there have been some production errors with the Audible version of the new book, with at least part of chapter sixteen missing. I've raised the matter through the relevant channels and the problems are being looked into. I'm assured that once the corrections have been made, listeners will be able to delete their current download and re-download the corrected version without any trouble.
I'm very sorry for this. If any of you are aware of the specific omissions, leave a message in the comments and I will then post the missing passages in this blog.
