Eric-Emmanuel Schmitt

I wanted to become a director before I wanted to become a writer. When I was 10, people would ask me what I wanted to be when I grew up, and I said, 'Walt Disney.' I wanted to make films. But I wasn't offered a camera. I was offered language. So I started telling stories in the theatre and then in my novels.

All these cities have sewer museums and tours, and all expose their underbelly willingly to the curious. But not London, arguably the home of the most splendid sewer network in Europe.
