The Infernal Investigators and Sontar's finest butler are on the case in our special Doctor Who crossover release!

Jago & Litefoot – London's resident infernal investigators, inspired by their adventures with the Doctor to continue the fight against the paranormal and the alien.

Strax – former Sontaran commander made a nurse by the Doctor, now serving as a butler to the Veiled Detective Madame Vastra and her wife Jenny Flint.

Now for the first time, Victorian England's greatest defenders join forces in Jago & Litefoot & Strax – the next Big Finish release from the New Series of Doctor Who!

Written by Justin Richards, and starring Christopher Benjamin, Trevor Baxter and Dan Starkey, this new double-disc release teams our heroes on a case they're not likely to forget...

Strax, the Sontaran butler to the Great Detective Madame Vastra and her wife Jenny, suffers a disorienting attack and mistakes the two Victorian investigators Jago and Litefoot for Jenny and Vastra and moves into Litefoot’s home.

Together, they are on the trail of a creature that is stealing brains, which may or may not be linked to a haunted house in London...
