Thanks to Picaroon, good Prize. He's doing double duty tonight, also in the FT as Buccaneer. These after Thursday's Indy as Rodriguez.
I thought it was a bit easier than usual, except for 6 and 9. Had to google to get 6 (I once knew it well, but had forgotten), and then 9 (LOI and quite tricky) fell into place. FOI was 10. Perhaps more "low-hanging fruit" than typical for Picaroon, but the less challenging entries were elegantly clued.
COD definitely 18, but I ranked 7 other clues as excellent, which indicates an enjoyable puzzle.
