 was the one hundred and tenth monthly Doctor Who audio story produced by Big Finish Productions. Released in July 2008 it was the second story in a series of stories featuring the Fifth Doctor, Nyssa and Thomas Brewster, although Brewster's appearance in the story is limited to a cameo near the end.

Publisher's summary
In a weird jungle valley, the Victorian explorer Rupert Von Thal saves Bloomsbury novelist Beatrice Mapp from a ghastly death in the grip of a monstrous mantis. But this is no Lost World of the dinosaurs. According to their travelling companions, the Fifth Doctor and Nyssa, all four have been transported back to a primitive Earth that should never have existed!

Further down the valley is the vast city where the scorpions live. Walking, talking, intelligent scorpions, ruled over by their cruel and sinister master. The Doctor and Nyssa are being drawn ever tighter into the clutches of... the boy that time forgot.

Individuals

 * The Doctor mentions Iris Wildthyme would be around in London in 1868 but they would not ask her for help.
 * Teegarna means "mouth on legs", matching Tegan Jovanka's description of herself. (TV: Earthshock)
 * Kranlee is probably named for Lord Cranleigh. (TV: Black Orchid)

Locations

 * The Scorpion King creates a city out of pure computations, the City of Excellence, watched over by Star, the remains of the alien computer the Cybermen used aboard the freighter.

TARDISes

 * The Scorpion King mentions the Doctor's TARDIS has a "flux capacitor" (perhaps as a joke), a time-travel component from Dr. Emmett Brown's time-travelling DeLorean in Back to the Future.

Time travel

 * The Doctor attempts to use Block Transfer Computations to time travel. It requires a quorum of twelve people.

Continuity

 * The Doctor has shaved the beard which he had grown at some point between November 1866 and November 1867 as the scientists at the British Royal Academy were not taking him seriously due to his youthful appearance. (AUDIO: The Haunting of Thomas Brewster)
 * The Doctor recalls Adric's supposed death. (TV: Earthshock)
 * Tegan was left at Heathrow Airport in 1982. (TV: Time-Flight)
 * The Doctor states that 'time is circular', possibly alluding to the AUDIO: Circular Time.
 * The Doctor, Nyssa and Adric all speak of Logopolis and the Logopolitans. (TV: Logopolis)
 * Thomas Brewster stole the TARDIS on 14 November 1867. (AUDIO: The Haunting of Thomas Brewster)
 * The Doctor is reluctant to ask the renegade Time Lady Iris Wildthyme for assistance. She had previously spent Christmas with The Doctor, Adric, Nyssa and Tegan Jovanka on one occasion. She came to dislike Tegan, later describing her as "that shrill Australian woman." Later in his fifth incarnation, The Doctor would encounter Iris once again on Excelis. (AUDIO: Excelis Dawns)
 * Later in his personal timeline, specifically during his seventh incarnation, the Doctor would meet Adric on one further occasion in PROSE: Cold Fusion. Those events occurred shortly after the events of TV: Castovalva and therefore prior to Adric's apparent death from the perspective of his fifth incarnation, whom the Seventh Doctor also met on that occasion.
