The author is so biased by his own personal pre conceptions, that the facts are not use in a cientific way but just as an excuse to difamate the Vatican, the Popes and the Catholic Churc in general. Does not worth reading it! All he states as truth is just an interpretation -personal one- over the facts. There is no single piece of evidence mentioned that matches the truth about the conclusions, which are merely subjective to the author's opinion. The whole book is based on another book on the same theme, by a rebel spanish catholic ex-priest called "Se pedirá cuentas", that also is a merely subjective interpretation on the facts, based upon a non-proved fact.
