Hello, if anyone's still around. I started on this late, because for some reason no Grauniads were delivered to our local newsagents. Eventually I ventured into the 21st century by doing it online. Like many people, I found some clues difficult, with 16d particularly puzzling, but unlike one or two people, once I had figured them out I thought all the clues were perfectly good, except perhaps "viper", which relies on a very archaic use of the word. Although I managed to fill in all the solutions, there's just one clue that I still can't fully parse. It's a clue which nobody else has mentioned as difficult, so I must be missing something really obvious. It's 3d. 2 word definition; no problem. Clue for last 3 letters; no problem. Between those two is a word which seems to be a clue to the first word of the answer. But that leaves 2 letters for which I can see no clue. Can somebody make me feel like a fool, by telling me what really obvious thing I'm missing?
