This picture illustrates a scene from the Patrick Troughton Dr Who story- The Evil of the Daleks. The Doctor has been forced to work for the Daleks who have stolen his TARDIS and are holding it hostage. Whisked back in time to 1866, the Doctor has manipulated his companion Jamie into going on a mission to rescue Edward Waterfield's daughter Victoria who is being held prisoner in the mansion of Waterield's benefactor- Theodore Maxtible. (This story flys around from one historical period to another in a whirlwind tour of 60's London, Victorian England and the distant planet Skaro, facilitated by 19th Century time-travellers dabbling with static electricity). Whilst Jamie has been on his mission the Doctor has been studying his actions and relaying his findings into a positronic brain. So he has discovered the elements that make up the Human Factor- the elusive characteristics that have thwarted the Daleks in their quest for universal domination. He has then transplanted this Human factor into the embryros of three Dalek creatures. When they are activated they behave like children and want to play trains with the Doctor (yes indeed) scooping him up on their fenders as they whiz around the parquet floor boards, whistling like demented kettles. The Doctor gives these three Daleks names-Alpha, Beta and Omega and because he is a clever clogs draws little Greek symbols on each of their casings. “ALPHA! BETA! OMEGA!” chirp the cheery little pepper pots. Little does the Doctor know but while he is doing all this, the Daleks are secretly working out the Dalek Factor- that which makes Daleks the uniquely evil things they are, so that they can transplant that into the minds of every Human Being in the Entire History of Earth. (Now what could possibly go wrong with a scheme as evil as that you say?) Earlier drafts of the story had the Doctor going back in time with Edward Waterfield to study an actual cave man, i.e. to really get to grips with the human factor. But that was never translated to screen sadly. The serial itself was wiped a few years after broadcast, although it has now been recreated as a full length animation published by BBC Worldwide. 16-07-23 .
