Hi Winnie. Think I can help you with some ... No.13, google the whole question and you should come up with www.crosswordgiant.com which will give you a possible answer. The same with No.41. Slightly cheating but I was tearing my hair out!! Re No.69, I think it is 'de' not 'du' + current PM = name of book.
Hope this helps.
Re my o/s ones, yes, please. Here they are:
47. Challenger's discovery - a missing planet (3,4,5). Is this something to do with the moon?
57. Sailor obtaining capital becomes a novelist (4,6)
60. Urge the family to meet the Russian(7)
85. Light vehicle went to city without Charlie - just to get a book (6,4)
88. Book someone to assist pianist (4,6)
92. Reconciliation when single chaps taken in by a non-drinker (9). ???? Teetotal ????
100. Apt position for this story of the demise of 40's adversary (2,5,7). I am thinking The Final ....... (As it's the last question)
Hope you can help with these or at least some of them & I will then concentrate on ones where clues have already been given.
Thanks again Winnie.
