gen2, the clue for 22 down is: London to draw to its close (4) and the answer is town. So the clue to 23 ac reads: Nameless novelist left in hotel in 7 down (battle) 24 down (town). Answer Austerlitz. Hope you can follow that!!
Thanks very much for the explanation Argee, the way the question was laid out it looked like 3 questions (23a, 24d & 24a) with reference to a fourth (7) and incomplete information given. esmerelda3 just ignored me.
to gen2 Sorry I did not intend to ignore you Hope I am forgiven as I will for certain need help again in the future.The truth was that I was not sure that I had indeed got the other answers correct and was going to seem very foolish. But actually foolish is better than rude. So another sorry
