the clue reads....
Appreciation of bowlerat the races (8).
(8) must be wrong because bothh grids only have 4 usable squares.
neither I down (A) nor 1 down (B) answer their half of the clue.
each half of the clue is only answered by reading A+B. once as an 8 letter word and once as two 4 letter words.
it seems undeniable that a mistake has been made. but as i said earlier it does not really spoil a jolly good puzzle.
