The Slate Money podcast had a recent episode of their "Money Talks" series that interviewed Ray Madoff, author of the new book The Second Estate. It was an interesting listen—could've been longer, IMO—and I appreciated the discussion about the history of the inheritance tax in the US and how it has become useless, largely through political inaction refusing to close tricks/loopholes. I'll be checking out from my library (once it's in the system!).
