The concluding part of this 16-episode "season" of 8th Doctor stories is as strong as those that have preceded it, making this a remarkable outing that has rarely missed a beat. I note that, after this, they are switching to shorter story arcs, or even anthologies, but this has been a high to go out on.
Crossed Lines/Get Andy/The Keys of Baker Street - These three episodes are technically separate, having different settings and being by different authors, but they're so thematically linked that they feel like one long story. This is the wrap-up to the Stranded story arc, as the Doctor comes to realise that the timeline he's in should never have existed and that he can therefore do what the TV show has always insisted he can't - go back in time to undo the events we've already seen. Each episode is a different attempt, one set on a night train to Edinburgh, one flipping between various settings (including a post-apolcalyptic Hull) and the other in the converted Victorian flats that have been the focus of the whole series.
The results are, of course, heavy on the time travel elements and, while there's plenty of threat, there are no monsters and little in the way of villains either. It also relies heavily on having listened to the previous episodes, finally resolving a lot of loose plot threads from earlier in the arc. The Curator also returns, although this time played by Colin Baker, not Tom (a necessity, one assumes, and largely handwaved away). It's not one for those who like straight action-adventure, but it's a clever set of stories full of drama and character moments and, especially in the final piece, an effective sense of impending doom. 5 stars.
The Best Year Ever - And then, a coda, that can finally address the key element of 2020 that was understandably missing from volume 1 (mostly written as it was, in 2019). It's entirely a character piece, a strong piece of emotional slice-of-life writing that evokes what was probably many people's experience of that year - although as a healthcare worker, it wasn't quite the same for me personally. No monsters, no villains, no real sci-fi elements, just 2020 as it actually was. Fantastic stuff that could never work on the TV show, but fits right at home with the themes of this audio "season". 5 stars.
