This short e-book is part of a series called 'The Wrong Doctors'. It takes an existing Doctor Who story and replaces the cast with another Doctor and his associated companions.
This story is The End of the World as written by Russell T. Davies for Christopher Eccleston's Doctor. This replaces him with William Hartnell's Doctor alongside his companions Susan, Ian and Barbara. Some plot changes have been used to reflect the cast change, but this is the intention in order to see just how different the stories would be if they had happened earlier, or later, in the Doctor's life.
Doctor Who remains the copyright of the BBC, the script and characters are copyright Russell T. Davies. Adapted by Stephen Henderson, 2013.
