Evolution by John Peel

Sarah Jane really wants to meet the journalist Rudyard Kipling, so the Doctor sets the co-ordinates in the TARDIS. Not materialising in quite the right place, the are pursued across the Devon Moorland by a massive feral hound.

Meanwhile something strange is going on, children going missing, strange lights in the waters of the bay, fishermen being found mutilated and graves robbed of their corpses.

A young Rudyard Kipling sets up search parties for the missing children while a ships doctor by the name of Arthur Conan Doyle is determined to investigate.

The Doctor and Doyle join forces to uncover a macabre scheme to interfere with human evolution - and both Sarah Jane and Kipling face a terrifying transmogrification.
