Huh.
Is it possible that nobody has yet suggested Aaronovitch's Rivers of London series?
I know that I have somewhere. And several others, too. I think it was a topic called "what else to read" or something like that.
Just received the latest comic "Action at a distance". Going to read it soon. As I understand, it's about Nightingale's past.
The next book will come in 2020 as I hopefully recall correctly.
Thinking about the posts, I believe they were one of the deleted ones because of the problems with the website. Couldn't find them yet.
Edit: found one of mine;). It's in Alternatives While We Wait, page 3, but I remember there have been others.
