I'm going to go with The Finished Mystery. There was, after all, SOME reason to send them off into spiritual captivity. Oh, right, but they kept selling that even after 1919...oops...
ONE book they printed shoots them down -which one do you think it is?
VOL. 1-2 INSIGHT ON THE SCRIPTURES.
THEY MAKE THE GOD THEY CLAIM TO LOVE, A LIER, IN VOL. 2, PAGE 332 IN THE SECOND AND PARAGRAPH.
AND CONTRADICT THAT ON PAGE 431 MORDECAI.
The "Flock" book. Anyone who reads it cannot help but see the religion for the pharisaical, nanny-religious micro-managing Cult it really is.
You can amass a preponderance of evidence for them being false prophets, and you would be correct.
Problem is the Governing Body have come up with a cunning strategy to keep the rank and file fooled. They have them all believing they are not prophets by fabricating their own proprietary defintion of a prophet.
It can get very frustrating when you have a mountain of evidence for their foul play and one barely intelligible explanation of what a "prophet" could rightly be is more than enough to satisfy the average Witness.
The Finished Mystery:
Michael is the Pope
Doctrines proved by measuring distances provided you take the Hoboken ferry
4 classes of believers instead of 2...
