Why doesn't JPB's character go after... (spoiler)
... the character of Richard? I kept waiting for this to come up as a possibility, once he heard Marion's true story, but it never did. I mean, losing nearly $28 million and being willing to give it all up without a fight?
Speaking of which, while I understand his reluctance to be open and honest with the private investigator (given his wife's involvement as an accomplice in murder), I still kept wishing he could somehow divert the PI's attention towards Richard-the-con-man. Now THAT was someone worthy of tracking down!
