Gavin de Becker
He's the author of The Gift of Fear, and I noticed he was referenced in the last episode's credits. Does anyone know what role he played in the last episode? Jarecki clearly was (finally) afraid of a guy he should have feared from the start, and I'm wondering if De Becker was consulted about the gamut of Durst's possible reactions, once Jarecki hit him with the evidence.
Watching The Jinx straight through was a draining emotional experience. It was so frightening because of the unexpected turn it took.
