FT Weekend prize puzzle from March 7
Cinephile brings us a mix of some clever clues (23A, 25A, 26A, 15D), some pedestrian ones (1D), a couple of familiar ones (15A, 17D) and a daring one (24A) for what I thought was a very satisfying puzzle.

Across
1. CASTLES IN THE AIR – CAST (actors) + SIN (wrongdoing) in LETHE (forgetfulness) + AIR (expose)
9. ORLANDO – OR (or) + LANDO[r] (as in Walter Savage Landor, poet)…with double definition

18. MARKET-LED – KET[t]LE in DRAM (drink) backwards
20. KITCHENER – double/cryptic definition
23. MINCE – double definition
24. AMIABLE – AM I ABLE (can I). This is an unconventional clue in that it has no definition. I think it’s okay.
