The Girl With the Millennium Trilogy Sequel?

Apparently, the longtime companion of the late Stieg Larsson (he’s the author of the wildly selling “Millennium Trilogy” – in case you’ve been living under a bookshelf) wants to finish off a fourth volume he had planned (and allegedly written about 200 pages of). There is an article at the NY Times about this, but not much more detail is provided. It will be interesting to see how this plays out. So much money is potentially at stake that I wouldn’t be surprised if we haven’t seen the last of Lisbeth and Mikael…
