'Persuasion' (4 Parts) by Jonathan Barnes

The Umbrella Man is back. But when the Doctor recruits UNIT's Scientific Adviser Elizabeth Klein for an off-the-books mission to the apocalyptic final days of Hitler's Germany, he isn't expecting Klein's hapless young assistant, Will Arrowsmith, to be joining them, too.

The Doctor isn't the only alien creature seeking to loot a very particular secret from a Nazi base in Dusseldorf, however. Strange and sinister beings are converging on the same time/space location in search of the scientist Schalk, whose experiments are the key to a devastating power...

The power of Persuasion.

Notes:
*Featuring the Seventh Doctor and Doctor Elizabeth Klein, and introducing Will Arrowsmith

*A Big Finish Audio Production

*Time-placing: Klein asks after Raine, whom she met in 'U.N.I.T.: Dominion'; however, this story takes place towards the end of the Seventh Doctor's timeline, just before the events of the Television Movie
