As the world teeters on the brink of war, Sherlock Holmes (Nicholas Briggs) and Doctor Watson (Richard Earl) are facing off against a criminal organisation which has been hiding in the shadows of British society for decades – the Lighthouse. 

The Adventure of the Politician, the Lighthouse and the Trained Cormorant - Part Two is the eighth and final episode of Sherlock Holmes Untold, a serialised audio adventure which has woven together an epic detective story from references in Arthur Conan Doyle’s stories to previously unexplored mysteries. 

As the Great Detective finally gets to the truth about the Lighthouse, the revelations will have great repercussions for prime minister Jasper Cranfield (Christopher Naylor), and potentially for the whole of Britain. 

Sherlock Holmes Untold is now available to purchase for just £24.99, exclusively here. This purchase will grant you access to all eight weekly episode downloads, as well as the complete serial as a download to own box set, available here. 

The Adventure of the Politician, the Lighthouse and the Trained Cormorant - Part Two 

England, the eve of the war. A corrupt politician. A conspiracy that has been in motion for decades. The Lighthouse. Sherlock Holmes. Dr John Watson. And a secret which could bring the Empire to its knees. Time now for the endgame. 

Sherlock Holmes Untold: The Adventure of the Politician, the Lighthouse and the Trained Cormorant - Part Two guest stars Luke Barton as Rosborough, Robert Whitelock as Anthony Kingsley, and Timothy Bentinck as Mycroft Holmes, as well as Harriet Kershaw and John Banks. 

Writer Jonathan Barnes said: “Working on all of these Holmes stories has been an absolute labour of love. I’ve been a huge Holmes fan since I was a small boy. So to get the chance to come in and play again, get that toybox out and put them together in interesting and new configurations – it’s always a real pleasure.” 

Lead actor Nicholas Briggs added: “This series of Sherlock Holmes has had such a cracking story. It’s real edge of your seat stuff. And it’s got a modern sensibility in it, even though it is set from the late 1800s up to 1913.  

“There are some eternal themes of human frailty and political machinations. It’s not just a dry old-fashioned story. There’s a real driving force of conspiracy and the horrible underbelly of politics and the manipulation of people. It’s got everything that a modern crime thriller has as well, but with the extra zest of that vintage setting. 

“It’s a really good jumping on point; if you’re listening to this and haven’t heard any of our previous ones, then there are plenty more before this, so you might like to go back and have a listen to those. We did The Hound of the Baskervilles, for example – can’t miss that!” 

There will be an ‘after show’ discussion for this episode in this week’s edition of the Big Finish Podcast, due to be released on Friday, with producer and presenter Iain Meadows joined by special guests Nicholas Briggs, Richard Earl, Emma Haigh, John Banks, Timothy Bentinck, Robert Whitelock, Christopher Naylor and Luke Barton, as well as Steve Wallace and Mark Jones from the Sherlock Holmes Society of London.
