I bought a copy of Dan Brown’s latest opus, Inferno, for £20 in London, in the bookstore featured in the movie Notting Hill. The name of the bookstore is, you guessed it, The Notting Hill Bookshop”. The shop had just sold two copies of Inferno since it arrived last week. So mine was the third—and last—copy in that particular bookstore on the day I bought it, May 26, a sunny and beautiful Sunday.
