Grave Matter
Justin Richards
 The Doctor and Peri arrive on a fog-shrouded island, not even aware of which century they have landed in. They soon discover that they are on a remote island of the coast of Britain where the local people have put aside modern inventions and lifestyle. However, when a dead body rises from its grave, and the local school children display uncanny adaptivity, the Doctor must discover the secrets of the scientific research carried out by the island's benefactor.
