I've been very busy today so, thus far, have only had time for a cursory glance , but my heart did sink a little when I saw that, in addition to it being an 'enter answers where they fit' alphabetical puzzle, I noticed at least two answers of 3 letters but no corresponding spaces in the grid.
It should be added, however, that due to my hand recently being in a cast - sorry, stookie, and still having to wear a strap on one at night (ooh e... don't Bren, please - just don't), I've been removing my glasses using just one hand with the entirely predictable result that one of the arms has snapped off them. My point being that, in my visually challenged state, there may very well be 3 letter spaces in the grid but I've just failed to see them.
