I've had quite a bit of fun and games with this challenging
puzzle, but, in sight of the winning post, my progress has halted! Could some kind soul give me a leg-up with the two
13 Across clues? On the left hand grid, unless I'm mistaken, part of the answer possibly repeats part of the clue, and in
the right hand grid will be where the extra letter will be added, I believe. (whatever that letter is).
I've attempted all the Guardian special puzzles for many years, many by Araucaria and his replacement,
Maskarade, but this latest effort is definitely one of the trickiest.
