Mmmm, yes, the Inquisitor threads have been starting later and later in recent weeks - are fewer people doing the Inquisitor? Or simply doing it later, after doing the Listener? Whichever, I have tended to assume by its lateness that most people have already completed the puzzle and want to confirm parsing etc.
In this case I think you would have to have an idea of the theme already to get what was being discussed here, certainly not from 'cold'.
