Dark Towers

Tracey arrives back at Dark Towers as darkness falls, meaning that the Tall Knight will soon appear. She convinces Lord Dark she is innocent, and he calls the police. Miss Hawk snatches the Golden Book of the Tall Knight and splits as all of Dark Towers plunges into darkness. Benger and Bunce go after her. As Tracey, Towser, Edward, and Lord Dark emerge from Dark Towers, the Tall Knight arrives, and scares the bad guys witless. As Benger, Bunce, and Miss Hawk are arrested, and the darkness lifts, Tracey gives Lord Dark the Golden Book of the Tall Knight. The Tall Knight has vanished, but throughout the house are strange sounds like laughter. The ghosts of Dark Towers are having the last laugh.

Bunce abandons his van and runs back to Dark Towers. Meanwhile, Miss Hawk has her own ghostly encounter in the Red Bedroom where she is keeping Edward, who now knows Miss Hawk wants the Golden Book of the Tall Knight for herself. The Friendly Ghost appears, and Miss Hawk runs from the Red Bedroom screaming. The baddies all discover the Golden Book of the Tall Knight hidden inside the lid of the studded chest, and the Friendly Ghost tries to summon the Tall Knight.

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.

Edward asks the Tall Knight for his help, but he says he can't help unless Tracey and Towser are there, because the old legend involves a boy, a girl, and a dog, and he vanishes. Luckily, Tracey and Towser are still hanging around, and they meet up with Edward after Towser drags her to the folly. The Tall Knight appears again, and instructs them to "go to the old library, and a gold key you will see, inside the inside of the Dark tree". While trying to crack the Tall Knight's riddle, Edward realizes that he meant the Dark Family Tree, and they find the final clue, which falls out of the spine of the book. The clue reads: "The knight's treasure will rest inside the inside of a studded chest".
