As with the other review, I am disappointed with this book. I cannot find the 'dose of poetry', as Live claim to be present; the language instead seems clumsy and stilted. It's an easy read, and a quick one too at only 106 pages (fewer really, since the book begins on page 11), but those expecting a supernatural tale of vampirism will be disappointed - for vampires read Anne Rice or Dracula instead.
I don't think that the book intends to be read as such though. It seems more a comment on the power of mistrust and suspicion within society. From the moment he is first arrested, the case against Favez spirals out of control as villagers call for his death. It is at times insightful and interesting in this respect but doesn't delve very far into this idea due to the length.
All in all, this book is only worth reading if you're particularly interested in this 'true' story (though I can't find any evidence that it is true). There is an interesting twist at the end but the book plods along at such a slow pace that it doesn't seem worth the effort.
