Since this is in the public domain I made an audio file of the book in two parts. You can download them here:
Saints and Psychopaths AUDIOBOOKI used a text-to-speech program for this, which has a few drawbacks, but it turned out pretty well. There are a couple of notable errors because the PDF was a bit blury and a few of the words were mistranslated by the program, but the errors are few and far between.
I really appreciate this book (esp the second half) Mr Hamilton must have been an amazing person.
