Castle is delving into the world of urban legends in one of their creepiest episodes yet, with Glee’s Romy Rosemont set to guest star. Rosemont will appear in episode 17 as Nurse Lockhart, a suspiciously sweet caretaker at a mental asylum. Beckett and Castle head to the hospital to investigate a young woman death.
A young woman appears to have literally been scared to death after watching a “haunted” DVD. This particular mystery finds Castle fearing his own date with the Reaper, after he accidentally watches the “cursed” video!
