Throughout William Gibson's Spook Country Milgrim is reading a book he found in the pocket of the coat he stole. Its a 1961 history of messianic medieval history.
Has anyone managed to identify the book?
I tweeted Bill Gibson @GreatDismal, including a link to this page. He has just answered "that one" (i.e. the one mentioned here above).
@GreatDismal What book is Milgrim reading in William Gibson's Spook Country?
