Paul Mc Gann (The Doctor), Julie Cox (Mary Shelley), Gareth Armstrong (Dr Johan Drossel), Christian Brassington (Alfred Stahlbaum), David Schneider (Ernst Bratfisch), Gwilym Lee (Count Rolf Wittenmeier), Claire Wyatt (Countess Mitzi Wittenmeier), Nicholas Briggs (The Cybermen)
Roll up! Roll up! To the great Viennese Exposition, where showman Stahlbaum will show you his most wonderful creation, the Silver Turk - a mechanical marvel that will not only play for you the fortepiano, the spinet and the flute, it will play you at the gaming table too!
But when the Doctor brings his new travelling companion Mary Shelley to nineteenth-century Vienna, he soon identifies the incredible Turk as one of his deadliest enemies - a part-machine Cyberman.
And that's not even the worst of the horrors at large in the city...
