I bought this in 1990 when it first came out after reading newspaper articles about a controversial new book exposing mossad secrets was to be published. The author was fired from the Israeli secret service,the Mossad and he gives his side of the story on that. Us readers can't really decide on that but the rest of the book is fascinating. Nearly half the book consists of his training,the various training exercises etc.This was what I was hoping the book would contain.The rest of the book has chapters on a number of mossad operations that Ostrovsky wasn't involved in,but very interesting nonetheless. Finally at the back of the book there are a number of diagrams showing the mossad organizational chart( very detailed ), organization of a station in an embassy,layout of the mossad academy,anti surveillance when meeting agents, and mossad reports.
