The Devil You Know (audio story)

 was the third audio story in the anthology Time War: Volume One.

Publisher's summary
The Time War has begun in earnest, and Romana must think the unthinkable. For a most dangerous mission, she selects the most dangerous warrior –.

But he will not be alone. Leela accompanies her old enemy as they begin an unusual interrogation.

What does Finnian Valentine know? And can Leela and the Master ever truly be on the same side?

Plot
Narvin informs Romana that is waiting in solitary confinement and that the war has given him purpose and changed him for the worse. With the Doctor refusing to help, Romana ignores Narvin's warnings and says that they need somebody intelligent, ruthless and, if necessary, to serve as a scapegoat. The pair meet with him in the cells.

With assault forces breaching the atmosphere, Finnian Valentine arms and activates an explosive weapon, expecting to die. Instead, he has conflicting memories about if he knew his parents, if he married a man or a woman and if some people that he knew were killed by the Daleks or the Time Lords. He wakes up, confused.

Romana and Narvin offer the Master a pardon in return for his help in recovering Valentine, a Barvan freedom fighter whose last known location was in the Blayling System where he and his allies were hoping to free slaves on Konoi VII, including his husband. The Master declines the invitation until Romana offers him the freedom of time and space with no questions asked; he insists on having his TARDIS, which Romana agrees to so long as Leela joins him on the mission.

Tasked with getting information on a possible weapon from Valentine, Leela and the Master depart for Konoi VII. Leela tells him that she does not like his new body as did not disguise his hate as this one does. After a bumpy ride, they arrive and go into the trenches, Leela aware that somebody is watching them. They find Valentine tied up in a bunker and are joined by the person who has been watching them: a second Valentine. The Master deduces that a temporal weapon split Valentine into two.
