Apple TV are filming Berlin Noir.

Could be good. You introduced me to those mysteries and I really enjoyed reading them. I wonder how closely they'll stick to the actual books?

There's very little information out there, but it looks like they're going with chronological order, with Metropolis as the first, which I think was the last one published.

It'll be interesting to see how they deal with the novels set in two time periods. The one that springs to mind is If the Dead Rise Not which is split between 1934 Berlin and 1954 Havana.
