Don of the Dead (S01E08)

Don and Ruth Ferguson are two of the nicest people you'll ever meet. They're devoted to the Catholic Church, they spend all of their time working at a homeless shelter and they've managed to recreate their lives after leaving everything behind to enter the Witness Protection Program. The only problem is: they can't stand each other, and they're too Catholic to divorce. Despite their misery, Ruth is devastated when she hears that Don has died in a traffic accident. As Mary investigates, she learns that the case is more complicated than it seems at first glance. The body in Don's car isn't Don, which begs the question: Could Don still be alive? If so, who has him? (iTunes)
