Dear all - I have just two clues left in the above crossword. They are as follows:
14 across - 'The matter with backup starts subsequently' and is three letters long. It's (I think) P-S
25 down - 'Another message revealing herald of the gods' and is 6 letters in length. The ones I have are as follows:
-E-M-S
Hoping you can help - thanks again in anticipation!
