The Sorrows of Vienna (Short Trips: Snapshots).

Prose Oh, so that's what that is. If nothing else, Steven Savile's story has filled in a blank about the Doctor's attire. The scarf Eighth wears is more properly called an "ascot" which probably won't be a revelation to you, but as someone who's only just about social climbing from George at Asda to M&S, call me fascinated (and yes, I do know what a fascinator is). A celebrity historical in which the Doctor becomes embroiled in the lovers grief of Goethe and inspiring the writing of Faust, this shows the influence of The Unquiet Dead (broadcast a couple of years before). Savile writes with a richly detailed, literary style which enjoys picking out the details of the Viennese landscape and society. But he doesn't quite have the ear for the Eighth Doctor's voice, notably when he keeps referring to Goethe as "poet" when he would more than likely simply use his first name. 
Placement: A powerful statement about the Doctor's guilt on how he left things with Cr'zz and Charlotte, let's assume it's set in the otherwise unexplored gap between The Girl Who Never Was and Blood of the Daleks.
