More details have been released about the upcoming fourth series of The Diary of River Song, coming this autumn courtesy of Big Finish.
The new series, which was originally announced last year, is set to star Alex Kingston as the time-travelling archaeologist alongside Tom Baker as the Fourth Doctor for the first time.
Now synopses for all four adventures in the series have been released, which will also see River come up against a brand-new threat – nihilistic time pirates, the Discordia:
4.1. Time in a Bottle by Emma Reeves and Matt Fitton
River is recruited by a rival to explore a star system where time no longer exists. Professor Jemima Still has picked up a signal from an impossible source and takes an expert team to investigate. But their mission is about to unleash hell upon the universe…
4.2 Kings of Infinite Space by Donald McLeary
With the Discordia on their tail, River and her friends run for their lives across time and space. But when your opponent can twist cause and effect to ensure victory at every turn, then escape may well be impossible.
4.3 Whodunnit? by Matt Fitton
Melody Malone finds herself in a Castle, with an assortment of strange companions. But guests are being murdered, one by one. Time is running out for a mystery to be solved. And Franz Kafka is hiding something in the attic.
4.4 Someone I Once Knew by John Dorney
River has tried in vain to keep the Discordia away from the Doctor. Now, as devils run riot through universal spacetime, her own past with her husband is being rewritten. There is one last hope for the universe. A love story – but one that must find an ending…
“For this series, we wanted to give River an adversary to match her, a real threat, so producer David Richardson and I set about thinking. For a time, we talked about possibly using the Daleks, but in the end decided on something original, so we created the Discordia.
“With no Time Lords to police things, the Discordia are essentially time pirates who can go back and re-engineer themselves and their evolution, to make themselves as intimidating as possible – and make sure they always win.”
Series four of The Diary of River Song is available to pre-order now from Big Finish ahead of its September 2018 release at £23 on CD and £20 on digital download.
Series five of The Diary of River Song will follow in January 2019, and will see River face no fewer than four incarnations of the Master. Series five can be pre-ordered individually at £23 on CD and £20 on digital download, or in a bundle with series four for £45 on CD and £40 on download.
