has the Sixth Doctor encountering Jamie in a strangely altered Scotland; the City of Spires of the title is none other than Grangemouth, turned into what appears to be an oil-producing metropolis in the eighteenth century. Or is it the ninteenth? And is it really. oil? And why doesn't Jamie even remember his meeting with the Doctor in 1745? None of these questions is actually answered, which I think is a new twist in Big Finish's generally successful shift to producing mini-seasons of each Doctor. A special shout-out to Georgia Moffett who plays a terribly posh but very confused young woman. ( )
