“tracked the members of the TARDIS crew moving cautiously down corridors that had been designed for something other than humans. It was the sound of this metal city that made the biggest impression on me. It was somehow unnatural, suggesting a vast construction made of curious alloys, flexing with the expansions and contractions of constantly changing temperatures. I watched with growing anxiety, a cushion firmly held in front of me (I was not a behind the sofa child) as Barbara was ‘gated’ along a particular route by unseen watchers. Finally she found herself cornered and confronted by one of the occupants of the city. We saw nothing more than her terrified reaction and the end of something that looked vaguely like a sink plunger… I had to wait a whole agonising week to find out what this alien that had terrified Barbara so much looked like.”
