Doctor Who – An Ideal World is out now.

Light years from Earth, a vast human spaceship hangs in orbit over a cloudy alien planet. The crew have been travelling in cryosleep for many years, looking for a habitable world to settle, and have at last located one with potential.

However, they’re not the only people to have arrived in this place. The TARDIS has landed on the planet’s surface. The Doctor, Steven and Vicki explore and quickly find themselves separated.

But it isn’t merely the hostile environment and rogue terraforming drones they’ll have to deal with. Something else is living on this world. Something deadly and waiting to consume.

It’s an ideal world. But ideal for whom?

Writer Ian Potter told us what inspired this story in the latest edition of Vortex: “The brief was just do a science fiction one – something a bit more like the series of the time, so I offered an idea about Earth colonists on an alien planet.

“It feeds on a concern of mine that’s also in The Bounty of Ceres (the third ever Early Adventure), that going into space is so hard, expensive and basically awful that I suspect we’ll not be sending the very best of ourselves out there. I think any colonists leaving the solar system are likely to be pretty driven and odd because well balanced people wouldn’t go!” Read more on this in our free monthly magazine, Vortex.

Cambridge, England, the mid 1930s. When the Doctor, Steven and Vicki get separated from the TARDIS they are forced to spend some time amongst the ancient spires of Sedgwick College. The college is mid-way through a leadership crisis following the unexplained disappearance of the Master of Sedgwick, Sir Isaiah Hardy. An election for his replacement is now taking place.

But is that all that’s happening in this seemingly peaceful location? The proctors are behaving in mysterious ways and the students are prone to bursts of unexplained violence. When one of his companions also vanishes, the Doctor realises that there’s more at stake here than control of an educational establishment. A dark plan is underway – one that threatens the entire future of humanity itself!
