This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: The Curious Incident of the Doctor in the Night-Time

Love a story with some good sci-fi and this delivers. Altering memories to convict someone falsely is one of those outlandish sci-fi ideas that parallel real-world events. 6 and Peri have been getting a ridiculous amount of murder mysteries and typically I'm quite tired of them but this one manages to be something fresh.

The Doctor believing himself to be an evil dictator was great and Colin Baker sounded like he had fun doing it. Nicola Bryant was pretty good here, having to carry the story on her own while the Doctor was indisposed. I'm a fan of how it all tied up neatly. Definitely one of the better outings for this team.
