'The Annihilators' (7 Parts) by Nicholas Briggs

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, it’ll take more than the combined efforts of the Doctor and UNIT to deal with an alien menace that stands on the cusp of the total destruction of planet Earth…

Tim Treloar (The Doctor), Daisy Ashford (Doctor Liz Shaw), Jon Culshaw (Brigadier Alistair Gordon Lethbridge-Stewart), Michael Troughton (The Second Doctor), Frazer Hines (Jamie McCrimmon), Karen Archer (DCI Denise Walker), Daon Broni (Sergeant Al Sinclair), Mark Elstob (Greshtrenor Leader / DC Lee Staniton / Doctor Daniels / Sergeant Major Roach), Bethan Walker (Greshtrenor Sub-Leader / Doctor Jane Broadbelt), Sam Stafford (Private Pritchard / Corporal Snell)

Notes:

*Featuring the Third Doctor, Liz, Brigadier Lethbridge-Stewart and UNIT, and the Second Doctor and Jamie

*A Big Finish Audio Production

*Time-placing: For the Third Doctor, this takes place during Season 7. For the Second Doctor, this occurs after 'The War Games', when he is working for the Time Lords; some of Jamie's comments seem to suggest it takes place early in those adventures, so I am placing it prior to 'The Black Hole' and 'The Two Doctors'

*When originally announced by Big Finish, the cover was altered to conceal the involvement of the Second Doctor and Jamie:
