Sure, sometimes recaps can be unnecessary, but sometimes they're actually welcome, especially if you missed just an episode or two and you want to get caught up. Below is a summary of what has happened so far on CBS' Harper's Island, which airs tonight at 10. It's actually a good little recap for those of us who missed the first two episodes (of course, the full episodes are available too). Catch up before there are so many episodes you say to yourself, "eh, I don't have time to watch this!."
