Doctor Who: The Deadliest Weapon

Jo Martin reads a thrilling original Circuit Breaker story featuring the Fugitive Doctor.

Masquerading as a resident in a luxurious space hotel, the Doctor is in fact on a dangerous mission to eliminate Kashan Akravar, a rogue weapons dealer who's attempting to auction blueprints for the deadliest weapon ever invented.

The Division - that shadowy Time Lord organisation - have briefed the Doctor to prevent the blueprints' sale at all costs. But they're not the only ones who realise the weapon's potential. When the hotel is attacked by Cybermen, intent on seizing the blueprints, the Doctor must use every ounce of her courage and ingenuity to hold them off.

Working with husband and wife Kel and Jinni, the Doctor finds puzzles and obstacles in her way. Whose disembodied voice is calling out to her? What is its connection with UNIT's Black Archive? And can anything prevent a cruel stroke of fate that will have unimaginable consequences for them all...?

Jo Martin - the Fugitive Doctor in the BBC TV series - reads this gripping adventure by Steve Lyons, the fourth instalment in the Circuit Breaker story arc, with David Banks as the Cyber-Leader.
