The presentation of this short trip is good, with a strong feel of the era of 4 and Leela, but unfortunately I did not find the story itself very satisfying. It sets up a mystery, presents a diversion with an interesting twist, but then never properly resolves the original mystery. I was left feeling that there were many things that the Doctor could have done to better deal with both the historical diversion and the outer mystery. All in all a story which never quite got going.
