Mr Patient - the point about this crossword is that it is a kind of a "cult" crossword, and part of the fun is discussing it ith fellow enthusiasts who don't want to be given the answers, perhaps a hint, and fellow feeling along the way.
The light dawned on the missing letter logic. However I cannot figure out which of the four possibilities is missing in 24ac. Very good crossword I thought. Thanks to all for hints.
I'm making some progress and I think I have 10a and it's significance.
Can anyone tell me if the 5 cards each 'appear' twice, or am I on the wrong track?
No, sorry for that . Indeed, each of them is used twice. It hasn't made any difference to my entries - or to yours I'm sure. It's just that I grew up with a different interpretation for 8 across! .
