Clever Dr Who

I am a bit away with the fairies due to a lovely temperature and I was thinking about Christmas Day's Dr Who.  There were vicious snowmen, a firm called Great Intelligence, a psychic entity that became self sustaining and disembodied by the end, and the Doctor gave a vital distraction to the Great intelligence in a biscuit tin with a map of the London Underground in 1967 on it, even though the programme was set in Victorian times.

In 1967 an episode of Dr Who was broadcast where a disembodied psychic entity called the Great Intelligence tried to take over the world using Yeti, or Abominable Snowmen, invading through the London Underground.  I was too young to remember the episode, but I read the book.
