I found out about this book from a list of the 100 best mysteries ever. It had atmosphere, I'll give it that (the smoke of the title is London fog). And the characters were colorful. But there were too many of them and a lot of them didn't have much to do. The interesting part of the mystery was solved very early on and after that it just became a manhunt. But if you like books set in London fog, you'll love this one.
