El Pais has an interview with Javier Cercas where he talks about what he thinks the novel is, does originality exist. He also spends about half of the interview talking about An Anatomy of a Moment and what his fascination was with the subject. For him, to explore how history informs the present is one of he most interesting things. Worth a watch if your Spanish is up to it. He has a some time strong accent, although in this video it didn’t seem to strong.
