Time travelling archaeologist and adventurer River Song will return on audio in 2017 – and this time she will be stepping into the past life of the Doctor, encountering two of his incarnations at once! Alex Kingston returns in The Diary of River Song: Series 2 alongside Colin Baker and Sylvester McCoy!

From the space exploration vessel Saturnius – which is heading to a destination that never gets any closer – to a doomed planet Earth and beyond, River’s journey will bring her closer to a new foe... and an encounter with both the Sixth and Seventh Doctors.

'We’re thrilled to have both Colin Baker and Sylvester McCoy appearing alongside Alex in this box set,' says producer David Richardson. 'I can promise that River and the Doctor might not necessarily be working to the same agenda. In fact, the two Doctors might not be working to the same agenda either...'

The four hour-long adventures are The Unknown by Guy Adams, Five Twenty Nine by John Dorney, World Enough and Time by James Goss and Eye of the Storm by Matt Fitton. The impressive guest cast includes Anna Maxwell Martin (Midwinter of the Spirit, And Then There Were None, The Bletchley Circle), Jessie Buckley (War and Peace), Ann Bell (Tenko, Wallander), Robert Pugh (Game of Thrones, Mr Selfridge, Doctor Foster), Dan Starkey (Doctor Who, Wizards vs Aliens) and Barnaby Edwards (Doctor Who).

In addition, 2017 will see the release of a Doctor Who: The Churchill Years Volume 2, in which Ian McNeice returns in the role of Winston Churchill – once again relating more terrifying adventures that featured his old friend the Doctor.

Also out in 2017 is Doctor Who: Classic Doctors, New Monsters Volume 2, in which legacy Doctors battle foes from the post-2005 series. Expect a return for some of the Doctor’s darkest and most terrifying enemies...

The series are produced by David Richardson, script edited by Matt Fitton, directed by Ken Bentley and Barnaby Edwards and the executive producers are Jason Haigh-Ellery and Nicholas Briggs.
