may be able to penetrate these barriers and shut down the warden's mechanical servants. The Phiadorans offer to guide the British through the forest in exchange for sanctuary on Earth, and Simmons is only too happy to agree. As they plan their assault, Turlough heads off, claiming he needs to rest—but in fact he intends to read more of the diary, to prepare for the coming assault. In the citadel, mechanical servants escort Haliwell and Emily to an audience with the alien warden.

However, the Doctor turns the tragedy to their advantage by coming up with a plan to break into the citadel using the deadly fungus. After two days’ march, the party reaches the citadel, where Turlough reads more of the diary to prepare himself—and accidentally finds mention of his own name. Now he will be forced to
