This was yet another superb episode of Castle. I thought it was a pretty good case with lots of twists and turns that kept me guessing all the way through the episode. I'm glad they keep developing the relationship between Castle and Beckett as the show continues, and it's quite obvious that they're starting to care more and more about each other. I'm still hoping Castle gets to get more involved with the cases, for example, he should be given a gun within the next episode or two; in my opinion at least. Overall though, I give this episode, Ghosts, a 9 out of 10.
