This Doctor Who story, written by Ian Stuart Black, was first broadcast in four episodes in 1966. It was the last story to feature Dodo as a companion.
It also introduces new companions Ben and Polly.
This audio version consists of a digitally remastered soundtrack with linking narration provided by Anneke Wills.
The TARDIS lands in London, near the Post Office Tower. The Doctor is unsettled by a sensation of a strange energy nearby. Visiting the newly completed Tower, the Doctor and Dodo meet Professor Brett, the creator of WOTAN (Will Operating Thought ANalogue), an advanced problem-solving computer that thinks for itself. Curiously, WOTAN even knows what the word ‘TARDIS’ stands for. In four days’ time, on C-Day, WOTAN will be linked to other major computers to take them over, including those of the White House, Cape Kennedy and the Royal Navy.
