In Chronotis’s study, books pile up, but The Worshipful and Ancient Law of Gallifrey remains missing. Romana reminds the Doctor of its power, though he downplays its importance. They ask Chronotis about it, who recalls a student borrowing books earlier. Meanwhile, Chris and Clare discover the book has no molecular structure and absorbs radiation. Chronotis remembers the student, Chris Parsons, and directs the Doctor to his lab. Skagra, dressed in stolen clothes, arrives at Chronotis’s and demands the book, using a sphere to attack Chronotis. The Doctor meets Clare, finds the book, and learns it’s 20,000 years old. Skagra returns to his Ship, reviewing Chronotis’s memories and seeking the Doctor. Romana tries to save Chronotis, but he dies after warning about Skagra and Shada. The Doctor is chased by Skagra’s sphere, which ultimately attacks him, allowing Skagra to seize the book.
