The Fourth Doctor and Romana have returned to Victorian London and have been reunited with old friends, Professor George Litefoot and Henry Gordon Jago. But this isn't a social visit. A new and terrifying crime spree is sweeping across London and the burglaries committed by 'The Knave' seem to defy all known logic.
Something very dangerous is living in the fog, and the time travellers and their friends can put a stop to it. But are they all on the same side?
Combining the Fourth Doctor with Jago and Litefoot is like combining peanut butter with different types of chocolate, at some point one gives up trying to listen to the story and just finds sheer joy in listening to the performances and the awesomeness of Tom Baker, Christopher Benjamin and Trevor Baxter.
It is the kind of story which could have come from the pen of Justin Richards who seems to love this period setting. And here he gives us a story where Doctor Who meets Jekyll and Hyde meets Raffles. Richards makes good use of K9, giving him some really funny one-liners, for once Tom Baker got pushed aside by John Leeson's good use of comic timing.
If there was one real complaint that I had with this story it was that Lalla Ward, as Romana, didn't get a lot to do. But I suppose this was a unfortunate side-effect of having so many larger than life characters to accommodate and the fabulous actors who play them.
But this is a lovely start to a new series of Fourth Doctor audio adventures from Big Finish Productions and it was the kind of story which reminded me why I love all of these main characters so much...
