In September 2018, Michelle Ryan reprises the role of mysterious cat burglar Lady Christina de Souza in a box set of four new audio adventures from Big Finish.
The thrill-seeking thief was first seen in the 2009 Doctor Who Special Planet of the Dead, co-written by Gareth Roberts and character creator Russell T Davies. At the end of that episode, after the Doctor declined to take Christina with him in the TARDIS, she flew off in the number 200 double-decker bus, destination unknown…
In the new audio adventures, Christina will encounter the villainous Slitheen and the formidable Sylvia Noble (Jacqueline King), the mother of the Doctor’s companion Donna.
