There were many books in my parents' home. I'm from a family of five children and we were all readers. And so by the time I left home, I had already read many books, and I was very interested in reading more. That was when I started to have the desire to write. But it wasn't like a divine apparition with angels and seraphins on high. Not for me, at least.

I think that's true of real life - we don't ever know anyone completely. Secrets are very important to creating a narrative work that's believable. The characters come into that world with secrets, as happens to all of us. As honest as we try to be in our relationships, we can never completely know someone. From a narrative perspective it's very important and pleasing - you want to have those secrets there. The secret is an essential part of the creation of the novel.

I'm interested in how memory and power come together in evil. These are obsessions of mine that appear throughout, like the theme of music. I know at some point or another one of my obsessions will emerge. You don't know how much I save in psychiatrist bills with this writing!

The reader has information about the characters that the characters themselves don't have. We all have our secret sides. Even I come to understand things about the characters only through the writing process, as I am going along.

For someone like you who's a British citizen this might seem strange. How can you ban a language? It turns out that you can. During the dictatorship it was illegal to speak Catalan. This is an experience that we Catalans have all had to varying extents. Some more tense than others, but it's something we all share.

Along the way, about certain things, you realize, "I don't know anything about this." You think, "Is this going to sound ridiculous?" So I pestered more than a hundred different people over the course of the book. And when I finished the book I gave it to six or seven trusted readers, who are always the same, but I also gave it to a brother of mine who's a doctor and I asked him to read it, and he was very helpful. It's good to have a group of trusted readers. As my kids have grown up, they've joined this group.
