An excellent episode with terrifying touches. Billionaire Harlow Gault has died, but he has managed to get a scientist to extract his brain and keep it alive in a fish tank with formaldehyde, waiting to find a young and athletic body and use it to perform the transplant. Gault's brain can move objects and speak through a special device. It is a pity that as always happened in this series when a villain manages to escape and promises to return, he never does. A continuation would have been interesting since the concept of a modern Dr. Frankenstein is a brilliant idea.
