Big Finish has released story and narrator details on the upcoming second series of The Companion Chronicles.
Set to be released in October, Mother Russia sees Peter Purves returning to the role of Steven Taylor alongside Tony Millan.
"It's 1812 and the Doctor, Steven and Dodo get ready to spend their winter in a Russian village. The French are on their way, but that's not the only invasion the travellers will have to deal with."
Helicon Prime, due out in November, features Frazer Hines returning to the role of Jamie with Suzanne Proctor.
"It's been a long time since Jamie McCrimmon remembered anything about his travels with the Doctor, but his visit to Helicon Prime just won't stay hidden... but why remember their murder investigation now?"
Nicholas Courtney reads Old Soldiers, the December release, a story for the Third Doctor told by the Brigadier. Toby Longworth guest stars.
"Old soldiers, comrades in arms - the Brigadier saw many fall during his years with UNIT, but perhaps none more tragically than those at Kreigskind. Called to help when a friend falls ill, how can Leftbridge-Stewart fight an enemy that can breach every defence?"
Leela returns in January, once again played by Louise Jameson in The Catalyst. This Fourth Doctor tale features guest star Timothy Watson.
"The pride of the Z'nai matches that of Leela of the Sevateem. Why would the Doctor imprison one in such an unlikely place, and what terrors will be brought about by letting it loose?"
