DOCTOR WHO MIND OF EVIL AUDIO CD

A dangerous adventure begins for the Doctor and Jo Grant when they visit Strangmoor Prison for a demonstration of the new Keller Machine. The device is said to extract negative emotions from convicted prisoners, leaving them pacified and reformed. But when it apparently goes wrong, a far more sinister purpose is revealed. This original TV soundtrack, with new linking narration by a member of the cast, is the six-part adventure from 1971.
