Bookride has just pointed out that a very handsome 4 volume set of the Stieg Larsson's Millennium Trilogy is due to be published soon. You'll have spotted the conundrum: trilogy? four volumes? So what 's in the fourth one? Well it is called Afterword. Stieg Larsson: Four Essays and an Exchange of Emails. It had to happen, in a world now short of the old-fashioned letter, though this is the first time I've noticed it. Can it be long before an academic puts together the selected texts of a deceased booker winner? Gr8.
