As it's moving towards the end of the week I feel comfortable in asking for a nudge. I've completed the grid and am horribly stuck.
I have the following as 'thematically entered' (missing letter clued but not entered); across: 10,11, 18, 29,34 down: 6, 17, 26, 32
But the letters don't seem to produce anything.
I'm in even more trouble on the thematically treated clues (a surplus letter?) Here I have only down: 4, 9, 14 and 28
33 across is a complete mystery!
Was this puzzle unusually difficult?? Any help appreciated.
