There have been many ways to invade the Earth, and the Doctor has seen them all. Or so he always thought - and then the human race wakes up one morning and discovers the world has been overrun by… small black cubes. Which then proceed to… do nothing much at all. A plan is afoot, humanity is endangered - but by what and how and, above all, when? For the first time in his world-saving career the Doctor has to call upon the least of his virtues: patience. And the Ponds face something possibly more terrifying than any world-ending apocalypse - the Doctor is moving in!
Not just a tale of alien intervention, this is also the story of a nice young couple who happen to have a bow-tied lunatic from space staying in their spare room. It’s halfway between an alien invasion movie and The Man Who Came to Dinner.
