This really isn't bad at all. The intrigue is of libraries and literature, with a running mystery and full of socially-bizarre-but-highly-intelligent freaky people. Although the story itself is good, what made the book for me was that a lot of the material - how libraries work, or the parallels with Boswell and Samuel Johnson - are actually real, not fictional and you finish the book having actually learnt something. And with a huge sense of relief that you are not quite as bizarre/idiosyncratic as the protagonists.
