HappyMan,
I think a better source to ask about is the Proclaimer's book. It is a much more detailed account of the JW history. However, like Faith On The March, it is chock full of errors, half truths, and major omissions.
One example is their account of Beth Sarim. They say is was for Rutherford's use, but they fail to talk about the religious reason Rutherford gave for constructing it. They also fail to mention that Rutherford lived like royalty, all through the great depression, while the flock could barely survive.
This book and the other two mentioned, are pure propaganda.
