Who is Who? A Time Lord from the planet Gallifrey with two hearts and 13 lives? A folk hero who entertained and enthralled through dark winter evenings in front of the TV? A rebellious iconoclast who toppled corrupt dictatorships and freed the oppressed? Or a bumbling weirdo who for 26 years fought rubber monsters and homicidal dustbins? The answer: all of the above and a lot more besides. The essential companion to every era of Who, packed with facts, figures, opinion, cross-referencing, essays and, of course, lunatic time-travellers in silly scarves.
