Who is Who? A Time Lord from the planet Gallifrey with two hearts and thirteen lives? A folk hero who entertained and enthralled us in the warm glow of our TV sets on dark winter evenings? A rebellious iconoclast who toppled corrupt dictatorships and freed the oppressed? Or a bumbling British eccentric who for 26 years fought rubber monsters in a cheap and cheerful BBC kids' show? Well, he's all of these things - and a whole lot more besides.

The story of Doctor Who is the story of British television in the final third of this century. It is also the story of the hopes and fears of generations of children - and grown-ups too - from the counter-culture 60s to the shallow waters of the 90s. Along the way there are shock revelations, melodramatic cliff-hangers and liberal doses of humour (intentional or otherwise); but be warned - there is also heart-ache, disappointment and death. Every taste is catered for in the world of Doctor Who.

As well as an introductory essay, each Doctor's era is put under the microscope with facts and informed opinion on all their stories. There's an in-depth reference section detailing further reading, fascinating and bizarre Doctor Who websites, and a short history of spin-off stories and merchandising.
