Thanks to Paul.
I found this less tricky than Paul's norm and on the gentle side for a Prize. But I struggled with two double definitions which required enough time to disqualify an "easy" evaluation.
FOI 4a, LOI 11.
22 parses as 1, 4 where 4 is in "...a **** it is to trouble the mind's eye..."
My COD is 21 because of a nice misdirection. Runners-up 2, 9, 4d, 12.
No obvious "Pauline" entries, to my slight disappointment.
