Someone from the future has arrived in Victorian London on the trail of a renegade… but that trail leads them to Henry Gordon Jago and Professor LItefoot.

So begins an adventure that will propel the Infernal Investigators into unknown territory, and an encounter with two people they should avoid at all costs.

Themselves.

Big Finish are delighted to confirm a brand new set of adventures for those Investigators of the Infernal, Henry Gordon Jago (Christopher Benjamin) and George Litefoot (Trevor Baxter), when Jago & Litefoot - Series 13 is released in April next year.

As producer David Richardson confirmed: "Jago and Litefoot return in 2017 - of course they do! We wouldn’t be without them. The four new adventures in Series 13 will take them in an unexpected direction, and see the return of some old friends too."

The titles and writers of these new stories have been confirmed now:

13.1: The Stuff of Nightmares by Paul Morris

13.2: Chapel of Night by Jonathan Barnes

13.3: How The Other Half Lives by Matthew Sweet

13.4: Too Much Reality by Justin Richards

Jago & Litefoot - Series 13 is available to pre-order now at £25 on Download, and £30 for the CD boxed set which also unlocks access to a free digital version. The gentlemen's other adventures can be found here.
