In more than one instance, today’s entry from Peto tested my ability to spell out the parsing in a comprehensible fashion . . .
. . . with a number of words and expressions that were unfamiliar to me. I would rate this puzzle as rather tough for a Tuesday, and certainly the sort of thing that I would have found very challenging back when I was a beginner. I think everything was fairly and conventionally clued, though, so hats off to Peto.
