Time travelling archaeologist and adventurer River Song returns - and this time she will be stepping into the past life of the Doctor, encountering two of his incarnations at once! 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. 2.1 The Unknown by Guy Adams. 2.2 Five Twenty Nine by John Dorney. 2.3 World Enough and Time by James Goss. 2.4 Eye of the Storm by Matt Fitton. Much anticipated by fans of Doctor Who both old and new, Big Finish are delighted to welcome Alex Kingston back again to reprise her River Song character first seen in 2008 on TV. She was seen as the Doctor's wife in the episode The Wedding of River Song, but her twisted timeline means she and the Doctor rarely see events from the same perspective! This time River gets to encounter not one but two incarnations of her husband the Doctor, when Colin Baker and Sylvester McCoy guest star as the Sixth and Seventh Doctors! Aside from her iconic turn in Doctor Who, Alex Kingston's well know in both the UK and US for her regular roles in E.R., Arrow, Upstairs Downstairs and The Knock. CAST: Alex Kingston(River Song), Colin Baker (The Doctor), Sylvester McCoy (The Doctor) with Anna Maxwell Martin, Jessie Buckley, Ann Bell, Robert Pugh, Dan Starkey and Barnaby Edwards.
