This Doctor Who novelization, written by John Peel, expands upon the 1965 television serial titled The Chase. The narrative follows the First Doctor and his companions as they are hunted across various eras and planets by Daleks equipped with their own time-travel technology. The group encounters historical figures like Abraham Lincoln and William Shakespeare before facing a robotic impostor of the Doctor on the jungle world of Mechanus. Amidst a destructive battle between the Daleks and the mechanical Mechonoids, the travelers find a stranded pilot named Steven Taylor. Ultimately, original companions Ian Chesterton and Barbara Wright utilize the captured Dalek vessel to return to their home in 1960s London. This book remains unique because the author chose to adapt Terry Nation’s original scripts, restoring complex scenes and character details that were omitted from the broadcast version.
