Edward asks his father if they have a studded chest, and he says there is one in the Old Tower. Miss Hawk overhears. Edward looks at the picture of the Friendly Ghost, and the ghost repeats his warning: "Beware of the bird with the brown feather", adding, "the hawk who hunts treasure". Edward now knows Miss Hawk is the bird with the brown feather, and rushes off to find Tracey. They head up to the Old Tower, opening the chest with the key that came with the last clue. It's empty. Benger and Bunce suddenly arrive with Miss Hawk. Bunce puts Tracey in the back of his and Benger's van, and drives off, but the Tall Knight comes to Tracey's rescue.
