The fascination for me writing about crime in Berlin was the idea that there was this much bigger crime taking place in the background, a fantastically epochal moment in history which is just going on. That just sort of makes the whole thing have a greater resonance.
There's a great tradition among the English of writing about Berlin. It's kind of a state of mind, almost. That even translates in terms of music. A lot of people go to Berlin with the idea that it's a state of mind.
