I increasingly like mad books, and I particularly like the kind of books that could never have got commissioned on the basis of a proposal. I like books that are not reduceable to a proposal. This new book of mine exemplifies that. It’s this crazy thing where I basically summarise, in a lunatic, unbelievably detailed way, a film that’s meant a great deal to me, Andrei Tarkovsky’s Stalker. It describes the journey into the forbidden zone where two people are taken, Writer and Professor, by this guide, a Stalker. At the heart of the zone it’s claimed there is a room where your deepest wishes can come true. That’s it, that’s what happens in the film.
