I'm the Doctor. I'm a Time Lord. I'm from the planet Gallifrey in the constellation of Kasterborous. And I'm the man who's going to save your life. This is the story of an impossible life — of a man who borrowed a spaceship, travelled through time and continually saved the universe — as told by the Doctor's friends, by his enemies, and by the man himself. Letters, journals, trial records, secret government files and the occasional bit of tabloid journalism reveal the never-before-told story of Gallifrey's last Time Lord.
