Barrett had his associates make their own moves. In the third season, he offered $10 million to get Simon out of the country which motivated both spy-wrangler Tom Strickler and career assassin Mason Gilroy to break Simon out for the price-tag promise. Now a free man and on the loose once again, Simon used his benefactor's resources to procure two bombs. In the fourth season, Barrett planned to have a team of freelance thieves rob the safety-deposit box and recover the Bible, but they failed the operation and were caught.

Nearly unconscious, Michael forced the steering wheel into a sharp turn that flipped the vehicle. The resulting crash left Barrett dead, Michael gravely injured, and the bible lost.
