I'm slightly foxed. While the clues are (slowly) yielding to me, I just counted the clues in order to try to identify the two unclued entries referred to in the preamble. No matter which way I count it - up/down/back to front - I see 38 entries in the grid and 37 clues. So there seems only to be one unclued entry (excl perimeter), of 11 letters.
Can anyone confirm, please?
