I finished this week’s Listener puzzle, “Toga” by Nod, this morning. I really thought I was going to finish last night — around 9:00 I had only solved about half the clues, but that turned out to be enough for me to figure out the “advice” spelled out by the extra letters, how to apply it, and what to do with the result. By figuring out in advance what was supposed to be the final step in the puzzle, I obtained several letters in the grid that I hadn’t actually solved yet, and that quickly gave me a few more answers. I was quite sure that I’d have it all nailed before I went to bed. But I got sleepy and ended up crashing with one clue still unsolved, and two more for which I was pretty sure I had the right answer but hadn’t yet worked out how the wordplay was supposed to work.
I finally solved them this morning — I was right about the two answers and worked out the wordplay, and the third clue turned out to involve some proper nouns I didn’t know that aren’t in Chambers Dictionary; thank goodness for the Internet. All in all, an enjoyable and not overly brain-busting puzzle.
