Knock Knock (TV story)
- You may be looking for the DWS short story.
Knock Knock was the fourth episode of the tenth series of Doctor Who produced by BBC Wales. This was the first Doctor Who story to be made available with a binaural 360 soundscape, released on iPlayer.
The episode expands the Doctor and Bill's relationship briefly when he tells her about the Time Lords, the alien race he belongs to and quickly mentions regeneration to her, but doesn't explain what regeneration actually is to her.
It also makes a reference back to the Doctor's granddaughter Susan Foreman, as Bill passes the Doctor off as her grandfather and refers to him as such. She has also told her friends about him; although, the Doctor doesn't seem to have much of a problem with it.
The Vault is also implied to not just have the mass it appears to have, instead being dimensionally transcendental. The prisoner inside is heard playing a piano the Doctor gave them. Nardole also suggests that the prisoner is aware of when the Doctor is starting to neglect looking after them.
Synopsis
Bill and her friends rent an old house to live in, but the floorboards and the walls are creaking, and there's a creepy Landlord lurking around. Can the Twelfth Doctor save the day as creatures come crawling out of the wood?
Plot
Bill opens her door to find her friend Shireen and four new housemates outside. Shireen introduces them as Felicity, Harry, Pavel and Paul. They head to the estate agents to find a place to rent together for student accomodation. However, they have a restricted budget and the agent that helps them shows them around places that are less than satisfactory. As the group leave the estate agents, on the verge of giving up, they are met by an elderly man named John, who ask them if they are looking for a place to live. He leads them to a magnificent old house, which they assume will cost them a lot to rent. However, the Landlord assures them that rent will be cheap, but specifies that the tower is off limits.
The group explores the house, and all except Bill are enthusiastic about the size of the place. Bill remains suspicious about the cheapness of the rent, suspecting there is a catch. Pavel asks to move in that night as his student halls are kicking him out, to which the Landlord happily agrees, getting everyone to sign a contract. That night, Pavel sets up his record player in his room and starts it playing; shortly afterwards he is surprised by something horrifying.
The next day, Bill is stacking up her belongings in boxes in her room. After everything is piled in one corner, she looks at her phone and counts down. The TARDIS materialises over the boxes, which end up inside. The Doctor opens the door and expresses his surprise that Bill has so few possessions.
Bill enters the TARDIS, suggesting that the Doctor hire it out as a removal service or package delivery. The Doctor is offended at the idea, thinking that removals is beneath a Time Lord. A little puzzled, Bill asks if 'Time Lord' is the Doctor's job description. He explains that it is the name of his species. Bill finds this hilarious, remarking how posh it sounds, to which the Doctor replies that it was the pompous attitude of his people that convinved him to run away. Bill asks if Time Lords wear robes and big hats. The Doctor tells her that the robes are true, but that Time Lords tend to wear big collars instead of hats.
When asked if he needs the address to find the house, the Doctor scoffs; however, he then relents and tells Bill to type it in so the TARDIS can land there. She asks if he sleeps in the TARDIS bedroom which she found. The Doctor tells her that Time Lords don't need sleep, except after big meals and regenerations. Bill is confused by his mysterious words, but the Doctor is evasive when questioned, saying it's enough to know that he's a Time Lord.
The TARDIS lands outside of the house, and the Doctor expresses his surprise that Bill and her friends can afford to rent it. Bill thanks the Doctor for helping her, telling him he can leave once her boxes are out of the TARDIS. However, the Doctor has noticed something off; he tests the breeze before offering to help Bill move her things inside. Bill is reluctant, seemingly worried that the Doctor's presence will be embarrassing and raise too many awkward questions, but he has already started carrying a box to the house.
Inside, the Doctor is greeted by Shireen, who knows about him. Bill passes the Doctor off as her grandfather, despite his protests. Felicity, Paul and Harry join them, having also been told who the Doctor is. Bill tries to get rid of the Doctor, who seems to relent and leaves the house.
That night, everyone notices that they somehow do not get signals on their mobile phones. They hear noises like something running upstairs. Hearing banging from the basement, all six investigate. However, the door opens by itself, to reveal the Doctor, illuminated by his sonic screwdriver. Bill notes she thought he went home. The Doctor ignores the comment, telling the kids that there is no washer and dryer, no central heating and that the outlets will not take their devices. The entire house is suited only for the 1940s. Shireen notes the same thing, thinking it was only her room; she decides to call the landlord.
Everyone heads into the sitting room, where the Landlord is suddenly waiting. He states he came by to check on things; the kids list of complaints, to which he states he will get to eventually. Taking note of the Doctor, the Landlord is told the cover story about him being Bill's grandfather. The Landlord guesses that he's helping with relocating Bill; the Doctor agrees. Seemingly remembering a bad memory, the Landlord states there is no worse feeling that than leaving children to fend for themselves. The Doctor thinks on these words, remembering when he did so. The Landlord states that he's lucky to have a daughter that is still under his protection; he leaves for the night. When Shireen attempts to open the door to follow him, the Landlord has seemingly disappeared.
Bill tries getting the Doctor to leave, by suggesting he sleep in "the car"; however, the Doctor instead decides to stay up with Felicity and Harry to listen to some music. Seeing she can't win, Bill decides to head to bed, followed by Shireen and Paul. Paul tries to ask Bill out, but she tells him she's gay; humbly, Paul notes he never had a chance. He heads into his room, messing with Felicity's fear of the house by making creaking noises on the wood. Once he shuts his door, Bill realizes that Felicity fancies Paul. At that moment, Paul is heard screaming in terror. After a moment, they think he's messing with them; however, when they attempt to open his door, they find it stuck.
Downstairs, Shireen and Harry ask the Doctor what he thinks of the music playing on her phone. He notes that it reminds him of Quincy Jones, whom he once filled in for. The bass player for Quincy's band turned out to be a killer Voc Robot in disguise; what's worse is that he couldn't even play. He then directs their attention to the door, which no longer has any open space between the entrance and the doors; they have been sealed in. Bill and Felicity join them, curious about the happenings in the house.
The Doctor has them go check on Pavel, while he, Felicity and Harry find a way out of the house. This leads the Doctor's group to the kitchen, where the shutters are rapidly shutting. Felicity panics, grabbing the shutters to stop it from sealing her in, and jumps out the window. Running, Felicity tries dialing 999 for assistance, but makes the mistake of resting on a tree. It absorbs her, as she screams in horror.
Hearing music still playing on a loop in Pavel's room, the two girls enter to find Pavel partially absorbed into the wall. Bill goes to turn off the music, but Pavel gives off a moan that suggests not to. The Landlord suddenly appears, shutting off the record and using a tuning fork on the wall; Pavel is absorbed completely. He tells them that Pavel is now at peace, one with the house. The Landlord further states that everyone must pay their dues, and the six signed a contract.
The two race out of the room and down the hall to a bookcase; deciding it must open a way into the tower, Bill and Shireen pulls books off until they find a switch disguised as one and pull it. A way opens into the tower and they run up into what appears to be an old bedroom. Shireen finds a music box, and opens it; a haunting melody plays prompting her to shut it. A woman's voice calls out, asking if her father has come back. Bill and Shireen believe this is the voice of the Landlord's daughter, whom says she hasn't had company for some time. She comes out of hiding, revealing herself to be completely made of wood. She introduces herself as Eliza.
Downstairs, Harry is panicking because the house managed to somehow get Felicity when she was outside. The Doctor tells him not to be scared, as it isn't useful in their current situation. Believing something is living in the wood, the Doctor begins knocking on the wood to get a response. He gives a hard bang on a cupboard and out pops an insect; he speculates this could be an insect no-one on Earth has seen before, or it could be alien, a wood nympth, or a dryad possibly. The Doctor tells Harry to get a box so he can examine it. However, things get worse when a whole swarm exits the wood and backs them into a corner. The Doctor pulls Harry into the cupboard, revealing that it's a lift.
The lift takes them down to the basement, where the Doctor and Harry discover the possessions of past groups of six that the Landlord lured to the house. Each group of boxes has a contract, and each goes back at least 20 years; the contracts are from the 30s, 50s, 70s, 90s and soon the 10s, when everyone that just moved in is eaten by the house. They head outside of the room, where the Landlord meets them.
The Doctor guesses the Landlord's daughter was dying, so he used the insects to keep her alive, but the cost was to feed them six humans every 20 years. The Landlord tells the Doctor that even though an older being (as the Doctor appears to be) will have less matter and energy, the insects will take what they can. Harry tries running upstairs, but has his foot trapped and is dissolved by the insects. The Doctor states that he is a doctor, and can help the Landlord with his daughter's ailment if it's not too late.

In the tower, Eliza tries reaching out to shake Shireen's hand. However, Shireen backs away in fear. She asks what's the matter. Shireen tries to cover her fear, but is soon consumed by the insects; her energy is then absorbed by the daughter. Moments later, the Doctor is lead into the room by the Landlord, who explains that he has brought a doctor to help her. Bill explains Shireen was taken, to which the Doctor explains was the case with Felicity and Harry.
The Doctor examines the daughter, coming to the conclusion that the Landlord brought the odd insects to her when she was sick to amuse her. However, the insects respond to music and awaken, such as the sound of her music box; when he checked on her the next morning, he found her wooden transformation was beginning, but her illness was cured. Bill then notes the oddity of it; why would a father spend time in the garden?
Realizing what Bill has, the Doctor remembers that humans don't live long, and if the father preserved his daughter 70 years ago, he shouldn't have been alive now as he didn't share in this immortality. Eliza becomes confused, as the Doctor explains that her memories have decayed due to the isolation and passage of time. The Landlord is actually her son, who did whatever he could to keep his mother alive. Prompted by the Doctor, Eliza realizes that her son has committed atrocities through his life just to keep her alive, in this inhuman state. She asks her son to let her die, but he refuses; taking command of the insects, Eliza thanks the Doctor for helping and has the insects devour her and the Landlord.
Without Eliza to act as the linchpin, the house begins crumbling. However, as a bonus, and the recent victims are revived and released. Everyone runs outside, just in time to watch the house crumble. His work done, the Doctor tells the kids to head back to the rel-estate office to look for a new home to share. He heads for the TARDIS as Bill an the others still gape at the sight of the destroyed house.

Back at the Vault, Nardole is doing diagnostics. The Doctor arrives with bags of takeout food, telling Nardole he can have the rest of the night off. When Nardole turns to leave, he hears Fur Elise play on a piano in the Vault; he notes that the Doctor doesn't know when to quit interfering until it comes back to haunt him. The Doctor firmly tells Nardole "Good night", sending him off.
The Doctor approaches the Vault, asking if the prisoner would like some Mexican food; he also has a new story. However, the prisoner doesn't respond until the Doctor mentions that people get eaten in his story; to this, the prisoner plays Pop Goes the Weasel. Taking this as confirmation, the Doctor smiles and unlocks the Vault to join his prisoner for dinner.

Story notes
File:David Suchet and Mike Bartlett - The Aftershow - Doctor Who The Fan Show
- The read-through for Knock Knock took place on 18 July 2016, and filming took place in August.
- David Suchet said in The Fan Show: The Aftershow that he used a real life experience of being covered in woodlice for the scene where the Dryads come crawling all over the Landlord.
- In an interview for Doctor Who Magazine #512, writer Mike Bartlett indicated that Harry was intended to be the grandson of Fourth Doctor companion Harry Sullivan, but the reference was cut. A possible remnant of this has Harry recognising the Doctor's name and calling him a "legend", despite the episode establishing that Bill is not yet closely acquainted with her new flatmates; another is the fact that Harry is partnered up with the Doctor for part of the episode. There is also a dialogue reference made to Harry's grandfather and his boyfriend stealing a piece of the Great Wall of China, however it is not clear whether this refers to Harry Sullivan or another grandparent.
- "Weird People" by Little Mix is playing extra-diegetically in the scenes where Bill and her friends are looking for a new house.
- Shireen refers to 11 Cardinal Road as "a freaky Scooby Doo house". The episode was partly filmed on location on the same property used for Wester Drumlins in TV: Blink - in which a character also referred to the place as "Scooby Doo's House".
- Not really noticed by everyone, but everything that Bill and her friends brought to that house either ended up buried or destroyed when it fell apart.
