I agree it’s a relatively easy set of clues, but at my stage with the Listener, it’s still a few hours’ solve, and I certainly only try the more difficult puzzles because of the occasional success, so perhaps they’re right to offer some hope now and again to encourage new solvers. That said, I have an empty cell in this one: 4th letter of 1d. I believe it’s a straightforward clue, as I have the 12 corrections, but I just can’t see it. Any hint as to the structure would be gratefully received!
