David Miscavige had kept more than 30 members of his church’s executive staff cooped up for weeks in a small office building outside Los Angeles, not letting them leave except to grab a shower. They slept on the floor, their food carted in.

Their assignment was to develop strategic plans for the church. But the leader trashed their every idea and berated them as incompetents and enemies, of him and the church.

Prove your devotion, Miscavige told them, by winning at musical chairs. Everyone else — losers, all of you — will be banished to Scientology outposts around the world. If families are split up, too bad…

The next evening, early in 2004, Miscavige gathered the group and out of nowhere slapped a manager named Tom De Vocht, threw him to the ground and delivered more blows. De Vocht took the beating and the humiliation in silence — the way other executives always took the leader’s attacks.
