Hi chrise
That wasn’t in fact my issue with 13dn. I can’t think of any other kings who share a 4 letter name with the surname of a writer in question! And this brings up the age-old question whether you should be able to solve all the clues in a crossword without having any of the crossers. In my view not, because that’s part of what a crossword is all about! But other views are of course available…. 😉
