The Fourth Doctor meets a musical icon in the fourth of a new series of novellas starring inspiring characters from history.

Sarah Jane doesn't know who she is any more.

She's applied for a job as a secretary at a run-of-the-mill office, with just one other co-worker.

He's nice enough. A little strange, a little charming, clearly an innovator. For a snappy dresser, though (Sarah loves the scarf) he's strangely quiet.

That's because, of course, he's the Doctor. Working with UNIT to try to restore Sarah's memories, he's found himself battling an alien group harvesting the minds of unsuspecting victims.

But he's already on the back foot, and as the alien hive mind draws in its followers, he's very much in need of a friend.

Enter legendary musician Fela Kuti. Another innovator - just as challenging, and just as charming. He might just be the one the save the human race.
