"Lewis sometimes felt that Morse was quite unnecessarily coarse." (end of chapter 7)

Re-reading the Morse novels from the start, it was surprising to me to see so much sexism and downright unpleasantness - like Life On Mars, but without the veneer of disapproval. Nicholas Quinn starts of well in this respect, by not being about the disappearance of young women, and also gains by not having anyone fall in love with Morse - whose unpleasantness was toned down a great deal in the TV adaptations. But it is still full of unnecessary comments on the appearance of young women, casual acceptance that women are just out to get a man (and that lewd comments from men are just part of normal interaction).

If you can ignore this, then it is a well constructed and interesting puzzle, easily the best in the series so far.
