Thanks for a typically informative post, Uncle Yap.
For those of us in the UK, 14ac has a topical reference: the MARSHALSEA was a debtors’ prison, which features prominently in Dickens’s novel ‘Little Dorrit’, a BBC adaptation of which has just finished its run.
The two long anagrams (1dn, 6dn) are splendid. 8dn has a rather good ‘Madama Butterfly’ connotation.
10ac is especially nice, since Osborne wrote Look Back in Anger, which receives a nod in the clue. 🙂
Orlando scores yet again with a well clued puzzle!
Excellent anagrams and witty cryptics. An excellent start to the week.
We had to look up MARSHALSEA, and had thought it a bit obscure – but then we’re not watching ‘Little Dorrit’ !
An enjoyable crossword. Not quite so solvable as you seem to imply, Uncle Yap, but very entertaining. Thanks for the lucid blog.
Overall, not a difficult one but got to agree with Uncle Yap – some witty cryptic definitions and elegant surfaces. The two big anagrams were clever but far too obvious – I was writing them in almost before I’d finished reading the clue.
Well done Orlando & Uncle Yap
I have to agree this was a nicely clued crossword, after one or two heavier going crosswords last week, a nice start to the week and this will give us new solvers heart for the tougher crosswords that im sure will follow in the week
