There appears to be an anomaly with the online version of this puzzle.
My father printed it late on Friday evening and on his copy the 17th clue reads...
"Character of old Noah's son"
I printed my copy around lunchtime today and my clue reads...
"Character of old Adam's son"
I am sure the later version is correct having solved the clue - but the first will be unsolvable.
I hope this helps any of you ultra keen Friday Nighters amongst our number.
Also would be interested to hear what is in the printed version should anyone still be traditional enough to pop out and buy a newspaper.
75% clues solved - but working too so I have my excuse.
Not looked at the grid yet, but pretty sure of 1a and 1d.
Bit early for hints!
