This was recorded probably around June 27, 2017 (if I trust the date on the file) and has sat on my hard drive waiting eagerly to be edited and posted. That, or it was aging properly and only finally got ripe. Take your pick! We have a modern episode of Peter Capaldi as the Doctor. We have mummy monks, vanishing priests, dates interrupted by the Pope, and a book that causes the reader to commit suicide. Who else can figure it out but the Doctor in this very Matrix-like episode.
