Thanks Chris and everyone for all the hints
I watched the Scandi-noir and then filled in all the solutions very quickly, sometimes rubbing out earlier ones and then finding others. There are some I can't parse, but I think they are all right. I'm glad I always fill in the grid in pencil.
I'd never have got anywhere without all the hints. Getting the theme certainly helped and it took me so long to see it.
Unlike the rest of you, I didn't enjoy it. It was too much of a slog and full of words I don't know or am insufficiently familiar with.
See you all next week when I hope to have a better go at it. Where is Brendan?
