A bit too clever, so many overlaps it's difficult to know where to start. James could also be made to work, and Callahan is only unique because of the unusual spelling, which is just nasty, and then to throw in the Chaucer group including yet more red herrings! Impossible.

Well, Ace, I managed it. Maybe I was just lucky. Thanks for a really enjoyable grid squareeyes.

Thank you for the feedback Ade. I'm glad you enjoyed it.
