Publisher's summary[[edit] | [edit source]]

This is a city of ghosts and no-one knows them better than Leanne. Twice a night she leads tourists to visit the most haunted sites - the Hanging Yard, the Witch Pool, the Screaming House, and, of course, the Catacombs.

Leanne's realised the ghosts of the city are real. Something's lurking in the Catacombs - an ancient force that has been growing in the darkness for centuries. Sabaoth is returning and they must be stopped before they devour the world. Leanne knows this, because a ghost told her.

A ghost called The Doctor.

Plot[[edit] | [edit source]]

Part one[[edit] | [edit source]]

Whilst Leanne is giving a ghost tour at the catacombs beneath a city on Earth, a man runs to an altar in a forbidden room and declares that the hungry Sabaoth is coming and needs Leanne. She hears the voice of the Doctor in her mind, apologising for the theatrics and asking if she believes in ghosts.

The Doctor answers a distress call and pilots the TARDIS to the catacombs in the 17th century instead of aiming for Heathrow. The travellers split up and Nyssa senses something which attacks Adric and pushes into her mind to make her feel afraid and hungry. After leaving a room with markings written in chicken blood and bones drained of energy, the Doctor and Tegan find Adric and Nyssa shivering on the floor and get them back to the TARDIS, but the ship is dead and the Doctor instead uses an emergency temporal shift to send his companions to safety. Tegan, however, chooses to stay and help.

Leanne now understands how the Doctor ended up being stuck in the catacombs and that all of the talk of hauntings over the centuries have indeed been real. She does not know how he got out, however, and he answers that he did not. He says that he died in the catacombs.

Part two[[edit] | [edit source]]

Having appeared in 1738, Nyssa is rescued from being burnt as a witch by Matthew Doyle and taken to his vicarage where she tells him about time travel and learns that the catacombs are currently owned by the reclusive Brotherhood of Sabaoth. Matthew visits them to find her friends and is kept waiting in the cold for hours, after which he kisses Nyssa and is rejected when he offers her a quiet life with him. Mrs Stubbs spreads the rumour that Matthew has been bewitched by Nyssa and, heartbroken and kept from his church, he stops defending her and she is to be drowned, watched by the Brotherhood.

The Doctor is without a plan and realises from Tegan's lethargy that she is being fed on by the alien. To keep her awake, he makes her walk with him around the catacombs.

Adric confesses in court to stealing a loaf of bread and is imprisoned pending execution. The cloaked Brotherhood attend his execution, drawn by the temporal energy around him and intending to feed it to Sabaoth, and he ensures that his name is mentioned in the newspaper. A noose is placed around Adric's neck and, despite his request for a few minutes more in the hopes that the Doctor might save him at the last minute, the floor beneath him drops as the crowd cheers.

Part three[[edit] | [edit source]]

Leanne goes to the Doctor's tomb in the catacombs and starts breaking into it using a fire extinguisher, but the Doctor stops her so as to prevent the question of whether he is alive or dead from being answered. She runs when the Brotherhood appear and the Doctor informs her that they are wraiths, come to use her as a psychic anchor for Sabaoth due to her having worn a groove in reality with her tours of places connected to him.

Tegan goes looking for a pickaxe in a TARDIS storeroom and is locked inside by the alien, who is able to speak using the ship and tells her that he wants to be reborn and devour the world. He sends her spirit ahead in time to the 1980s using her own energy and the telepathic circuits to serve as his anchor and she tries to warn people, but returns to her body unaware of how successful she was before apparently dying in the Doctor's arms. He puts her body into a stasis chamber and fights to stay awake.

Katya and Martin play with a ouija board and Katya becomes possessed, leading Martin to seek out Father Angelo to exorcise her. Whilst the Brotherhood stand outside the building, Father Angelo performs the ritual and she gives a warning about Sabaoth, saying that her name is Tegan Jovanka.

Part four[[edit] | [edit source]]

The Doctor temporarily disappears from Leanne's mind because of her fear overloading her telepathic channels and tells her the next day that Sabaoth has put a trigger in her mind, meaning that she will be in danger if she returns to the catacombs. He tries to make Leanne help him by causing poltergeist activity, but she blocks him out and psychically blows up a café. At work, she is approached by the Brotherhood and takes them to the Temple of Sabaoth in the catacombs, accepting that Sabaoth will return and she will die.

In the catacombs, the dying Doctor builds a wall to prevent himself and the TARDIS from being discovered and deduces from Tegan's transportation that his ship remains in the catacombs in the future. He enters a healing coma and interfaces with the TARDIS's telepathic circuits to project himself into Leanne's mind, but she sends him back in the café and he uses the recharged TARDIS to collect Adric, Nyssa and Tegan and join Leanne in the catacombs, disguised as members of the Brotherhood. Thanks to a telepathic trigger that the Doctor placed in Leanne's mind, she is able to use his power to prevent his return.

Leanne realises that the Doctor arranged Adric and Nyssa's mysterious disappearances to create two of the stops on her ghost tour and learns that Tegan was placed in a stasis chamber before death to keep Sabaoth from feeding on her, the Doctor waking her up some time after rescuing his other two companions. With the TARDIS no longer projecting, the city will no longer be home to ghostly goings-on; Leanne does not mind, however, as she has never really believed in ghosts.

Notes[[edit] | [edit source]]

Alternate cover
  • This story was recorded on 17 and 19 July 2017 at The Moat Studios, London.
  • Adric and Nyssa do not appear in the third episode.
  • Although the concept of the Heisenberg's uncertainty principle is used here, a proper distinction needs to be made between its depiction in the real world and its depiction in the story. In the real world, the principle typically refers to non-relativistic Quantum Mechanics, in which time is usually treated as merely a type of parameter rather than an observable. It also has a somewhat analogous uncertainty relation, usually dubbed the "Time-energy uncertainty relation".[1][2] Note that this uncertainty relation is different to the one Heisenberg formulated, although they are related. This is different yet again in Relativistic Quantum Mechanics and Quantum Field Theory. In the context of the story, it is only used as an analogy to explain why the TARDIS over-shoots its destinations a lot. It should not be taken literally.
  • The Doctor explains that certain events in time can become fixed points in time if they are observed, however, if they are not observed they can potentially be changed. The Doctor wasn't sure whether he was dead or alive while inside Leanne's head and so claimed that they couldn't see his body to check whether he was dead or alive, lest he really be dead and they create a fixed point in time. He refers to the situation as a "Schrodinger's ghost", a reference to the famous Quantum Mechanics thought experiment Schrodinger's cat.
  • Tegan mentioning a Peter Cushing film is actually a metafictional reference to the films Dr. Who and the Daleks [+]Loading...["Dr. Who and the Daleks (theatrical film)"] and Daleks' Invasion Earth 2150 A.D. [+]Loading...["Daleks' Invasion Earth 2150 A.D. (theatrical film)"], where Cushing portrayed the mysterious Dr. Who.
  • The Doctor asks rhetorically that if Leanne does "ghost walks" for a living, why would she not want to mention she has an actual ghost in her head? "Ghost Walk" is, of course, the title of the story.
  • Sacha Dhawan, who voices the characters Reverend Matthew Doyles and Katya's boyfriend, would later go on to play the Master in 2020 for Series 12 opposite Jodie Whittaker as the Thirteenth Doctor. Interestingly, this audio contains more than one actor to have appeared in some capacity on the show (besides the main cast) as Fenella Woolgar voices the central character Leanne and had previously played Agatha Christie in TV: The Unicorn and the Wasp. In fact three people from Ghost Walk would later be in the same TV episode The Power of the Doctor that of Peter Davison, Janet Fielding and Sacha Dhawan. With Dhawan playing the Master, only Davison and FIelding plays the same characters that they had played in Ghost Walk.
