It's the telegram Constance never wanted to read: DEEPLY REGRET TO INFORM YOU LT-CMDR H CLARKE LOST IN ACTION. CLASSIFIED OPERATIONS. 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! Director Jamie Anderson is the son of Gerry Anderson, the producer behind such shows as Thunderbirds, UFO Captain Scarlet and Terrahawks. His work influenced generations, and Jamie inherited this storytelling gene! Colin Baker's Doctor has proved hugely popular to fans of the Big Finish Doctor Who releases, with his television adventures continued across a range of stories with both old and new companions. The Doctor's companion in this story - Mrs Constance Clark - is played by Miranda Raison, star of TV's Spooks. Mrs Clark works at Bletchley during the War, and worries about a husband lost in mysterious circumstances.
Lisa Greenwood returns to play the popular Philippa "Flip" Jackson, a former companion of Colin Baker's Sixth Doctor. CAST: Colin Baker(The Doctor), Miranda Raison (Constance Clarke), Lisa Greenwood (Flip Jackson), Matthew Cottle (Henry Clarke), Joel Fry (Kinvar/Rogers), Oliver Cotton (Major Callahan), Kate Kennedy (Ana).
