Jo Nesbø is the king of crime novels, with more than 55 million books sold worldwide. The Norwegian author spends the winter in Malaga to climb near the Caminito del Rey, write and even go to football.

He has just published the horror novel The House of Night, in which he approaches some of his fears. “I have never had a method. I spend too much time writing and I need to have fun, to have that feeling that I'm inventing something new,” he says.
