Oh, no. Not another "Castle buys into fringe beliefs" episode. I don't believe a mystery writer would be as gullible about these things as Castle's been portrayed to be this season. For one thing, mystery writers are masters of misdirection and thus should be able to see through hoaxes and deceptions more easily. For another, falling back on the inexplicable would be cheating in a mystery story; there'd be no satifactory solution that could be deduced. So I don't see that appealing to Castle's mind, since as we've seen in earlier seasons, he reflexively casts every situation as a potential mystery plot. Solving mysteries is about critical, analytical thinking and refusing to take things at face value. A credulous mindset, a willingness to buy into psychics and UFOs and the like purely on faith, just doesn't seem consistent with that.
