On an episode of Castle, a mindreader was found dead. The victim's daughter, Penny came to NYPD homicide detective, Kate Beckett. After the Killer was found, and was in holding, Penny told Beckett that "there was something very important in a dream that she needed to tell her about, something strange, but perhaps extremely meaningful, something about a man named Alexander." She told Beckett that one day, this Alexander character would save her life. It just so happens that Castle's given name is Richard Alexander Rodgers, but for his pen name, he changed it to Richard Edgar Castle. So, now I will leave the rest to you. Is he the one that Penny had a vision about?
