This book is once again relatively very well written, documented and implemented as are other books of this formidable duo of authors. This novel took me with the protagonists of the book in the universe so well described in this transatlantic luxury Britannia appointed or are happening even awful things supernatural. I was enthralled and I could hook his reading until the end ... I confess that end really left me on my hunger and that deserved to be better worked. This book is still very good but it does not represent for me the best of Preston and Child.
