Double the excitement! Double the adventure! Double the danger! When Earth's defences face an extraordinary extra-terrestrial threat, it's going to take the combined forces of two Time Lords to save the human race from annihilation. 
 
In this seven-part, full-cast audio drama, the Third Doctor (Tim Treloar) and his trusty allies, Brigadier Lethbridge-Stewart (Jon Culshaw) and Dr Liz Shaw (Daisy Ashford), investigate a murder while a series of natural disasters threaten to tear the Earth’s surface apart.  
 
But when the Second Doctor (Michael Troughton) and his companion Jamie McCrimmon (Frazer Hines) show up inexplicably, things get even more complicated – and more deadly – than anyone could possibly have imagined.  

Doctor Who – The Third Doctor Adventures: The Annihilators is now available to own as a collector’s edition CD (+ download for just £19.99) or digital download only (for just £16.99), exclusively here. 

There’s something in the water at Lewgate Docks. Something strange, and green, and deadly. Summoned to the North of England by a mystery informer, the Brigadier finds his investigations hampered at every turn by the local police. Just what are they trying to hide? 

While the Doctor uncovers sinister goings-on in the city morgue, Liz attracts the attention of something unearthly. But with Time running out, quite literally, the Doctor, Liz and UNIT aren’t the only ones to find themselves targeted by a world-shattering alien menace... 

... because they’ve got a previous Doctor and his best friend Jamie in their sights, too! 

Writer and director Nicholas Briggs said: “I think the most thrilling part of my job at Big Finish is trying to capture the spirit and feel of a particular era of Doctor Who that is special for me.  
 
“For the structuring and pace of The Annihilators, I wanted to give it the feel of a police procedural. It’s kind of Line of Duty 1970s style – with monsters! 
 
“It’s also a throw-forward to our new The Second Doctor Adventures range. I think it really brings a lovely interaction into the story and I wanted our listeners to get an early audio listen of Michael Troughton in his father’s role. The Second Doctor Adventures don’t start until August but I thought that was far too long for everyone to wait.” 

Tim Treloar added: “It’s a wonderfully-written script that contains many a red herring and many a twist. A seven-part story is rare in the Doctor Who world. It’s new territory. 

“Working with Michael Troughton as the Second Doctor was a great treat! I know a lot of fans have been crying out for a meet between the Third and Second Doctor. It was very exciting knowing that was going to happen.” 
 
Michael Troughton, the new voice of the Second Doctor (a role originated on television by his father, Patrick Troughton) said: “The idea of mixing the Doctors is great. The more the merrier! Nick’s script is very clever. I thought this would be a really fun tribute so I’m really happy to try and produce – as near as possible – the mischievous Second Doctor.”
