The Haunting, sometimes marketed as Jago & Litefoot & Strax, was a special release from Big Finish Productions, uniting Henry Gordon Jago and George Litefoot with Strax. It was one of the company's first releases featuring elements from the new series of Doctor Who.
Strax, the Sontaran butler to Victorian investigator Vastra and her wife Jenny, suffers a disorienting attack and mistakes Jago & 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...

- The first question of Mrs Multravers lists several numbers starting from 1. The correct answer to the question implies that all these numbers, including 1, are prime. While in the modern mathematics it is accepted that 1 is neither prime nor composite, it was not uncommon to consider 1 prime at the time the story is set. In particular, the entry for Number published in 1890 in the 9th edition of Encyclopædia Britannica stated that every positive number was either prime or composite and explicitly listed 1 as prime.
- The idea that Jago and Litefoot are confused for Jenny and Vastra by Strax was suggested by Steven Moffat. (BFX: The Haunting)
- Strax refers to Ellie as "lad", believing her to be male. He has similarly misidentified Clara Oswald's gender on a number of occasions. (TV: Deep Breath et al.)
