I had been holding off listening to the second series of Winston Churchill after having mixed feelings about the first series. Finally, I had a long-ish car journey to myself so I had a listen to this first story of the second series, and I enjoyed it more than I thought I would.

This story is part-way between an audio book and an audio drama. It's essentially a two-hander with alternate narration from Winston Churchill and Silurian detective Madame Vastra. It leans in to the fan-service aspects of such a cross-over. We get casual mentions of Sherlock Holmes and Jagp and Litefoot (both Big Finish ranges) and a description-only cameo by the 11th Doctor.

The narration is told mostly in flashback, with the conceit that we are hearing readings of both Churchill's diary and the Casebook of Madame Vastra. This flipping back and forth could become confusing, but all it does in this case is add some padding to what is essentially a very simple story with a relatively underwhelming ending.

Despite all that, I still enjoyed it. I guess I am a sucker for crossovers.
