I’m not ashamed to admit that I binge-watched season three of “House of Cards” the weekend it appeared online. (OK, I’m a little ashamed.)

For those of you too busy or well adjusted to spend 13 hours in front of a screen, this is the Net­flix show about a morally bankrupt politician’s rise to power. The lead character, Frank Underwood, after stints as House majority leader and vice president, has schemed and murdered his way to the White House by season three. Yet broad executive power hasn’t brought Frank or his wife, Claire, his literal partner in crime, much personal or professional satisfaction.
