While there is some interesting first-hand detail, this book is highly self-serving. The author deserves credit for gaining access to Arthur Rudolph and his family, but that comes along with the customary risks of any such endeavor--the need for access generally means that the subject is allowed to dictate his own story. Much of what Rudolph said in this 1987 book contradicts documentary evidence that was released over the course of the 1990s. Obviously the author was not privy to this evidence, but it certainly calls many of Mr. Rudolph's claims into question.
