Dimwitted Dusty has now filled in the spaces but there are two about which I am half-bemused!
15 across Reservation for twenty grains (7) ~ the answer is 'scruple' ~ but where do the twenty grains fit in?
22 across Turn to list before film's over (6) ~ the answer is 'rotate' (turn, yes) ~ but where is the rest coming from?
squarebear, bibblebub and kayakamina ~ you all have MY Best Answer Award. Thank you all very much. I don't know why I didn't try my trusty Chambers for scruple ~ it is there! and ET, oh dear! Must do better!!
