I was already thinking about Five Red Herrings earlier this week when someone else mentioned it - and I reread it quite recently. It was actually the first one I bought, in a village thrift shop, having never heard of Sayers or Wimsey, because I went 'ooh, Galloway! Ooh, a map of train lines!' - train timetables being one of my favourite things, and planning journeys to places I will probably never actually go one of my standard cheering-myself-up pastimes!

I still like it - I enjoy anything that's full of details of how people lived, and I like the muddle of characters and the way they link together and their views on each other's lives and work.

It was Gaudy Night that I bounced off hard, a few years later, having tried to read it because everyone said it was brilliant. I don't think I realised that the two things were related until I tried GN again about five years later and got on a lot better.
