David Tennant's Doctor is reunited with Derek Jacobi's Master in a new Doctor Who audio drama series. Tennant played the Tenth Doctor, taking over the long-standing mantle of the iconic Time Lord from Christopher Eccleston in 2005. Over the next four years and 47 episodes, Tennant earned global success and critical acclaim. Tennant is considered by many to be one of the best Doctors from Doctor Who's entire run, and when he regenerated into Matt Smith, fans were sad to see him go.

Since 2016, Tennant has also continued his Doctor Who work away from the screen with a series of audio adventures for Big Finish, which sees the Tenth Doctor embark on new adventures.
