Doctor Who and the Giant Robot

This unabridged reading of a classic Doctor Who novelization is narrated by the Fourth Doctor, Tom Baker, and is based on a serial from the original TV series. "Look, Brigadier! It's growing!," screamed Sarah. The Brigadier stared in amazement as the Robot began to grow...and grow...swelling to the size of a giant! Slowly the metal colossus, casting its enormous shadow upon the surrounding trees and buildings, began to stride towards the Brigadier. A giant metal hand reached down to grasp him... Can Doctor Who defeat the evil forces controlling the Robot before they execute their plans to blackmail--or destroy--the world?
