A brand-new four-part adventure featuring the Master’s exploits in the Time War.

In a Time War, there is a crime that not even the Daleks would dare consider. But the Master has more than considered – and he is ready to commit...

When his TARDIS returns to Gallifrey carrying his corpse, a chain of events ensues that will change established history. Old friendships will be destroyed and dark alliances formed, as the Master exploits a terrifying truth.

Even for the two most powerful races, time can be rewritten.
