Quicksilver (audio story)

 was the two hundred and twentieth story in Big Finish's monthly range. The story saw Flip Jackson join the Sixth Doctor and Constance Clarke in their travels after an almost three year absence from the main range.

Publisher's summary
It's the telegram Constance never wanted to read:

Those classified operations concerned a top-secret military project code-named 'Quicksilver'. A project based in Vienna. A project with alien connections.

But bombed-out Vienna is not what it was before the war – with its Strauss music, its glamour and easy charm. It's not the time nor the place for a happy reunion. As Constance Clarke is about to discover...

And as the Doctor is about to discover, too!
