Dark Towers

They go about their mission to stop a group, led by Miss Hawk, from stealing the treasures of Dark Towers.

Part Two (The Man in the Picture): Tracey and Edward encounter two men, Benger and Bunce, and soon become suspicious of the two.

When they follow Towser to the Red Bedroom, they meet the Friendly Ghost, who is the man in the picture that spoke.

Part Four (The Clue in the Book): After the Friendly Ghost disappears, a woman named Miss Hawk walks into the Red Bedroom, and offers to help Tracey and Edward look for the treasure.

Part Six (The Tall Knight's Folly): 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.

Part Seven (The Dark Tree): 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.

While trying to crack the Tall Knight's riddle, Edward realises that he meant the Dark Family Tree, and they find the final clue, which falls out of the spine of the book.

Edward now knows Miss Hawk is the bird with the brown feather, and rushes off to find Tracey.

The Friendly Ghost appears, and Miss Hawk runs from the Red Bedroom screaming.
