Hi
I've got the grid filled in (apart from the blank cell) I've got the quotes - but "three down solutions combine to deliver the first" (quote I assume) this is where I'm stuck, I can't find words meaning the first quote or find three down clues that I can anagram to make the quote. Obviously I'm being thick, please can anyone point me in the right direction on this and the letter to put in the blank.
Thanks in advance.
