Doctor Who Secret History Audio Cd

"Starring Peter Davison as the fifth Doctor. The final in a trilogy of stories in which somehow the Doctor finds himself in an earlier point in his life, but he's really not the man he was. The fifth Doctor finds himself in a historical setting - Constantinople of the 6th century - but why is he here with the companions of his first incarnation? The conclusion of a trilogy of stories putting later Doctors in earlier roles: a special event marking Big Finish's two hundredth main range Doctor Who story! Peter Davison as the Doctor teams up with Maureen O'Brien and Peter Purves as they reprise their characters Vicki and Steven from the early 1960s!"
