Dr Matunovic was Tito's personal doctor.

The book you mention is most interesting. I happen to have heard of it before, and remember someone from Macedonia telling me some years ago that this Tito's doctor was intrigued by his patient's personal history. Like, for example, how did someone with a supposedly poor background could play (well?) the piano and speak 7(?) languages... This same person said to me that Tito was thought of being a friend of Churchill and a Freemason and that the real Tito had died in some war and the one we know as such was a Pole aristocrat that stole his identity with the purpose of making "a Socialist experiment called Yugoslavia"(!). I don't know what of this is fact, what is what I call "thesis" or what part of this is mere theory. I only remember him mentioning this book and some local TV shows made about Tito. But, since then, I have been most curious to know more about this book, but I can't read the language in which it was written. Which is it, by the way? Serbo-Croatian? Could you please briefly describe me the content of this book, so that I can possibly present it to someone who's willing to do some research about it? Are there any other good sources concerning this same subject that Tito's personal background might not correspond with the official story?
