Tim Treloar’s Third Doctor and Alex Kingston’s Professor River Song are colliding in a brand new box set of adventures from Big Finish

Big Finish have revealed more details for The Diary of River Song: New Recruit, coming in October 2021. These full cast audio adventures find River Song spending some time on Earth, helping UNIT as their new scientific advisor. We already knew she encounters with Brigadier Lethbridge-Stewart (Jon Culshaw) and Dr Liz Shaw (Daisy Ashford). But now we know River Song’s timeline also crosses with the Third Doctor; but what will he make of his wife from the future?

The script editor for the series is Matt Fitton, who described the appeal of adding River to the UNIT family. “Season Seven of Doctor Who had a special flavour all of its own, and here we’ve stirred in the added ingredient of River Song, so we can see a bit more of Dr Elizabeth Shaw saving the world with UNIT! With the Doctor away, the Brigadier now has two brilliant, clever women by his side to offer scientific advice on the odd and unexplained.

“I’ve always thought the character of Liz was gone too soon on TV, and it’s wonderful that we now have Daisy Ashford giving her more adventures. What will she make of River – someone with the capacity to be equally as infuriating as the Doctor? And how will the Third Doctor himself react, when he finds a cuckoo in his nest?”

The Diary of River Song: New Recruit

UNIT – the secret organisation established to deal with the odd and unexplained on Earth and beyond.

The redoubtable Brigadier Lethbridge-Stewart leads the troops, and for scientific guidance relies on two brilliant advisors: Cambridge genius Dr Elizabeth Shaw, and UNIT’s newest recruit – that mysterious traveller in time and space known as… River Song.

The Blood Woods by Lizbeth Myles

With the Doctor indisposed, Liz is a little put out to find that the Brigadier has brought in another scientific advisor to take his place. But when Liz and River investigate otherworldly goings-on in an English village, they soon find themselves relying on each other to survive.

Terror of the Suburbs by James Kettle

Liz has moved house. It seems she’s found a suburban utopia – until River Song arrives. There is more to Fetter Bailey than manicured lawns and endless soirees. Dangerous creatures prowl the hedgerows, and something lurks in the freezers…

Never Alone by Helen Goldwyn

River believes Intertraxia is ahead of its time, but it’s already shipping innovations in entertainment and computing around the world. When a dead man is found dead with alien technology implants, UNIT investigates. Liz and River are about to discover that those connected to the network are never alone…

Rivers of Light by Lisa McMullin

In a Yorkshire mining town, strange temporal distortions and rivers of light crossing forests are enough to get the Brigadier’s attention, and UNIT is mobilised. But the Doctor is back, and he wants to know who’s been messing around in his laboratory. River’s reasons for being on Earth are about to be revealed…
