Unlike Dryden, I found the down clues less difficult than the across ones, and it was only when I got the first across clue that things fell into place as regards the grid and the two-word description. However, I'm still not sure about the three-word title. Is this an example of the two-word description? I can come up with a plausible three-word title for a possible example of this thematic item (making use of all but one of the letters in the bottom row and a definite article from elsewhere in the grid), but my problem is that this isn't a generally used title for that particular work. Also, I've not got the significance of the puzzle's title yet.
At least this week's puzzle didn't take up all of Sunday, unlike last week's puzzle!
