I can't believe I'm the first to post on this four-day-old puzzle! Is there another thread? I have so many unresolved problems that I think I'll wait until I find out if it's been wrapped up by others.
Many thanks - I find it can be hit and miss using the Search box on this site. If you put in the title + number it rejects it, so I generally try 'Inquisitor' and 'IQ' but I never would have thought of 'inquisitor' all in l/c.
