The Tall Knight's Folly - S1.E6

Tracey is literally framed by Benger and Bunce (they stuffed a little gold picture into her pocket at the end of the previous episode), and she is sent away by Lord Dark. Edward finds a torn piece of paper in the Old Coach House. He seeks help from the Friendly Ghost, and learns that Benger and Bunce were the "two B's" the ghost warned him about. Reading the clue, Edward and the Ghost come to the conclusion that the next clue is at the Tall Knight's Folly at the end of the old wall. Edward goes there, and meets the Tall Knight who demands to know "Who comes to the Tall Knight's Folly?".
