Christopher Benjamin and Trevor Baxter will reprise their roles as Henry Gordon Jago and Professor George Litefoot in the first story of the series, written by Jago & Litefoot Script Editor Justin Richards. The release begins a bumper run of nine stories, which also feature the return of two old enemies, as Romana's past begins to catch up with her...

Set during the 18th Season of the Classic TV series, The Fourth Doctor Adventures Series 6 will feature contributions from a range of top talent, including new-to-Big Finish writer Adrian Poynton (White Van Man). The remaining stories have been written by Cavan Scott and Mark Wright, James Goss, Phil Mulryne, Jonathan Morris and Andrew Smith. Marc Platt (pictured here with Tom Baker) has penned the two-part series finale.
