Wendy Padbury (Zoe Heriot), Charlie Hayes (Jen)
Zoe Heriot remembers everything. But she remembers nothing.
A genius with instant recall, Zoe's mind has been purged of her memories of travelling with the Doctor and Jamie in the TARDIS. And years later she is in deep trouble - prosecuted by the mysterious company that has evidence that she has travelled in Space and Time.
Except Zoe knows they're wrong.
But if that's the case, why is there proof that Zoe was in Uzbekistan in 1919.
Can the memory cheat?
