I thought 18dn was a bit odd and it looks as if it contains a misprint, although perhaps I am missing something: the paper version certainly says ‘Nobody’s has’ when it should surely be ‘Nobody has’. It looks like one of those mistakes people make nowadays (since word processors arrived) when they are changing something and forget to delete a word, in this case ‘has’.

In any case, I wholeheartedly agree with Kathryn’s Dad’s comment about ghost themes.

To answer Allan’s question at no 10: no.

That’s a great spot by Ben, and no doubt there are some other Potter fans out there who are congratulating themselves on finding all seven. But that’s the art of creating a ghost theme – don’t make the puzzle unnecessarily complicated because of it, so that if you can’t see what’s going on, then it doesn’t matter.

I thought the three-letter clues were cleverly put together today.

I shall show the completed grid to Kathryn’s siblings when they get in from school later, because they are big fans, and it might just make them a tiny bit interested in the world of cryptics. Or more likely:

Me: ‘Look, there’s a Harry Potter theme in my crossword today.’
Them: ‘Whatever.’

That’s green teas (anag) for you …

Thanks to Phi for a nice end to the cryptic week.
