TARDIS: "And a new sound: a terrible creaking, like the death throes of a animated wooden creature.  A familiar sound.
    The shouts turned to horrified gasps.
    The blue box was disappearing from within the flames.  The villagers drew back as one, awe-struck by the disintegration of this magical artefact.  As it faded into nothing, and no plague appeared to strike them down, a few raised a ragged cheer.  The Devil's temple, somebody claimed, had been razed.  They would not see its like in this colony again.  But Susan knew the truth, though it was almost as dreadful to contemplate.  The TARDIS had dematerialised.  Faced with possible death, her grandfather had chosen to flee.  To leave her behind."
