The Sixth Sense is Death
A novelization of two episodes: The Beginning and The Experiment. "Within hours of accepting a holiday assignment designed to develop her psychic powers, Sharon Macready found herself made prisoner, cut off from civilization in an eerie and frightening laboratory. And the only neighbors she seemed to have were an old man of a hundred and four living in a glass house, and twelve zombies with super powers, all called Tommy Atkins. So that when Craig Stirling and Richard Barrett came to England to investigate a biological warfare establishment, all three found themselves caught up in a process that seemed destine to convert humanity into robots, and wipe the face of the earth with bacteriological extinction."
