Something has thrown the natural order out of balance – but Jo’s own world has also changed forever. It turns out she is not the only one investigating.

The Conservitors by Felicia Barker (2 parts) - On the planet Viltris in the 49th Century, a regime obsessed with statistical analysis of risk has created a force of robots to protect its citizens.

The Iron Shore by Lizzie Hopley (2 parts) - Landing on the troubled, sea-faring planet Mercator, the Doctor and Jo encounter Callis, a ‘cursed man’, the last surviving member of his family line - and the curse is keen to find new victims.

As Jo lifts the lid on the tensions within the local community, the Doctor finds himself in deep trouble.
