Doctor Who: Grand Theft Cosmos

This is a rather fun crime caper set in 19th century Sweden, with the Doctor and Lucie trying to steal an allegedly dangerous piece of artwork. The story has a good balance of action and humour, without straying over the boundary into outright comedy.

The Headhunter returns, bringing the first real sense of continuity this season, and proves an effective character beyond her role in the previous season. Lucie also has quite a lot to do, being rather more competent here than in some earlier episodes.

The play is enjoyable, bringing to mind some of the banter and one-liners of the modern TV series. The premise for what is going on behind it all works well, with the actual nature of the artwork proving rather more important than initially appears to be the case. As so often, it's hard to know how well this would have worked as a longer story, but the one-hour length suits it perfectly.
