[IainGrace]

A Listener-free week for us. Good luck to all who tackle this one.

For those joining this, there's an earlier thread.

I do have a solution, but it requires 1D to be 4 digits long (and so the bar immediately above the 8 to be removed).

Apart from that, I think I might have to give up on this one.

I know there's an earlier thread but I've got to second Iain's comment. I spent about 20 minutes less on this than last week's exceptionally easy, but still enjoyable, crossword.
