Number one on our list is really a no-brainer. Who else woud get the top spot on a run-down of inventive time travel storytelling other than the late, great Douglas Adams? In City of Death (written under a pseudonym by Douglas Adams and Graham Williams from an idea by David Fisher), squid-headed Scaroth, last of the Jagaroth, is caught in an explosion at the beginning of the Earth and scattered in pieces through time (a precursor to Clara's similar predicament in the Name of the Doctor). From different points in history, the Scaroths are working to boost human society to the point that they can create time experiments to stop themself from destroying their spaceship - the reason for the explosion that caused Scaroth to be scattered in the first place. The Doctor and Romana realise, however, that that explosion was the very thing that created life on Earth. Scaroth must be stopped! Consumate plotting from the king of quirky sci-fi, City of Death has the mix of humour and clever plotting that we now associate with the current incarnation of the show. Most definitely Doctor Who's original timey-wimey writer, Adams is also a massive inspiration for the writer who coined the term 'timey-wimey.' Blimey. It seems Doctor Who itself is a big ball of wibbly-wobbly timey-wimey stuff. As the Doctor himself almost said in Blink, I'd better stop now before this article gets away from me...
