Borders didn't have another copy of the offending book, so the girl on the information desk gave me a refund and advised me (in an amusing stage whisper) to go and buy it from Waterstones instead. So off I trotted to Waterstones, only to find that the copy on their shelves had exactly the same problem in exactly the same place. Looks as if it is a problem across a whole print run. How peeving. And what a particularly annoying place to have an enforced pause, just before the climactic showdowny bit!
