Alternative timeline

 * In an alternative timeline in which Nazi Germany won World War II and eventually conquered Africa as a result of the Seventh Doctor and Ace accidentally leaving laser technology in Colditz Castle in October 1944, the Mau Mau Uprising against Nazi rule took place in Kenya. The Luftwaffe was sent in immediately. On the orders of the Führer Adolf Hitler, they proceeded to carpet-bomb the tribal areas and wipe out most of the native population. Within three years, a virulent plague had broken out in Kenya which killed many German soldiers. In 1957, Hitler placed Elizabeth Klein in command of a team of medical doctors and scientists who attempted to discover the cause of the plague. However, they were unable to do so.
