'''''{{StoryTitle}}''''' was the fourth episode of [[Series 10 (Doctor Who)|series 10]] of ''[[Doctor Who]]''. It was the first ''Doctor Who'' story to be made available with a [[binaural sound|binaural]] 360 soundscape, released on [[BBC iPlayer|iPlayer]].

The episode expands the Doctor and Bill's relationship briefly when he tells her about the [[Time Lord]]s, 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.

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 that the Doctor is starting to neglect looking after them.

== Synopsis ==
[[Bill Potts|Bill]] and her friends rent [[11 Cardinal Road|an old house]] to live in, but the [[floorboard]]s and the [[wall]]s are creaking, and there's a creepy [[John (Knock Knock)|Landlord]] lurking around. Can the [[Twelfth Doctor]] save the day as [[Dryad|creatures]] come crawling out of the [[wood]]?

== Plot ==
Bill opens her door to find her friend [[Shireen (Knock Knock)|Shireen]] and their four new housemates outside. Shireen introduces them as [[Felicity (Knock Knock)|Felicity]], [[Harry (Knock Knock)|Harry]], [[Pavel (Knock Knock)|Pavel]] and [[Paul (Knock Knock)|Paul]]. They head to the estate agents to find a place to rent together as student accommodation. 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 asks 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 that 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. 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 convinced him to run away. Bill asks if Time Lords wear robes and big hats. The Doctor replies 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, as the friends are gathered in the lounge eating takeaway meals, they discuss odd things that they have noticed about the house. Felicity complains that there is no mobile phone signal whilst Harry reports hearing tapping, like footsteps, when he was unpacking. Paul and Shireen laugh this off and tease Felicity until a loud banging from the kitchen makes everyone freeze. The group squabble over who should investigate until Bill takes the lead and the others follow. As the clattering continues from the pantry, Bill summons her courage and opens the door, surprising the Doctor, who has been poking around the room with [[the Doctor's sonic screwdriver|his sonic screwdriver]]. Bill is exasperated, saying she thought he had gone 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; it seems nothing in the house has been updated since the 1940s. Bill takes the Doctor to one side and tries to persuade him that there is no mystery involved, but the Doctor is unconvinced, mentioning that the creaking they heard in the trees outside could not have been caused by the wind because there wasn't any. He unsuccessfully tries to convince the group to rent a different house. Paul decides to call the Landlord about updating the house but Shireen reminds him that there is no signal.

Everyone heads into the sitting room, where the Landlord is unexpectedly waiting. He claims to have come by to check on things when he notices the Doctor, and Bill tells him the cover story about him being her grandfather. The Landlord guesses that he's helping with relocating Bill and wistfully states that there is no worse feeling than leaving children to fend for themselves. The Doctor thinks about these words, remembering when he did so. The Landlord says that he's lucky to have a daughter that is still under his protection, before asking if everything is satisfactory. He gets a barrage of complaints about the house from the students and says that he will do what he can to address these concerns; though he seems untroubled, almost amused by their problems. When Harry asks how they get into the tower the kindly tone of the Landlord vanishes and he becomes sinister. As he leaves, the Doctor follows him and asks him who the current Prime Minister is. When the Landlord cannot answer, it confirms his suspicion that there is something amiss. Remembering that they need a washing machine, Shireen opens the front door to follow him, but the Landlord is nowhere to be seen.

Bill tries getting the Doctor to leave, by suggesting he sleep in "[[The Doctor's TARDIS|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; before she goes, the Doctor suggests checking on Pavel, who hasn't been seen all day. As they head to their rooms, Paul tries to ask Bill out, but she tells him she's gay. He takes the news well, and politely backs off, noting that he never had a chance. He heads into his room, teasing Shireen for her fear of the house by making creaking noises on the floorboards. Once he shuts his door, Bill asks why Shireen didn't take a room next to her, as they had planned. She is defensive over the question, leading Bill to conclude that she fancies Paul. At that moment, Paul is heard screaming in terror and the girls begin to doubt that this was part of his joke. When Shireen knocks on his door, answering knocks reveberate all around the hallway and doors begin to slam shut; Bill and Shireen flee upstairs.

Downstairs, Felicity 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 was worse, he couldn't even play. He then directs their attention to the front door, which has sealed shut. They hear loud banging sounds from the kitchen and follow the noise to see the shutters slamming themselves closed. Felicity panics, and, grabbing the shutters to keep them from closing, escapes through the window. She hastily dials the police, but is standing close to a nearby tree; it absorbs her, as she screams in horror.

[[File:Puvel trapped on the wall.jpg|thumb|Bill and Shireen find Pavel.]]
Hearing the violin music still playing on a loop in Pavel's room, Bill and Shireen enter to find Pavel partially absorbed into the wall. Shireen goes to turn off the record, but Pavel blinks rapidly to communicate that they shouldn't. The Landlord suddenly appears and says that "hope is its own form of cruelty", lifts the stylus from the record; Pavel is absorbed completely. He tells them that their friend is now at peace, one with the house. The girls are horrified and realise that they will be next. When Bill challenges him, the Landlord replies that everyone must pay their dues, and since the six signed a contract, it is time to pay.

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 pull 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, who 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.

[[File:Dryad Knock Knock.jpg|left|thumb|The Doctor discovers what is literally inside the house.]]
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 presses hard on a cupboard door and a gap opens to release a giant insect; like a woodlouse with glowing antenna. He speculates this is likely an alien being, a wood nymph, or a dryad possibly. The Doctor tells Harry to get a box so he can examine it, however, they have to abandon this plan when a whole swarm pours out of the wood. The Doctor pulls Harry into the cupboard, revealing that it is 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, identical to the one Bill's friends have signed, which are dated 1997, 1977, and 1957; every twenty years. It becomes clear that the Landlord has been luring young people to the house to feed them to the insects. Hearing footsteps, they head outside of the room, where the Landlord meets them.

The Doctor confronts the Landlord with the names of his previous victims, whose fate he seems to regret, but when the Doctor asks why he feeds people to the insects, he insists it was necessary. He explains that his daughter was dying until she was saved by the insects and that she must survive. Harry panics and attempts to escape, but his foot is trapped in the wooden staircase and the Landlord summons the lice with his tuning fork. They swarm over Harry and absorb him. The Landlord turns his attention to the Doctor, who backs away from the insects, and in desperation, suggests that as a doctor he can help the man's daughter.

[[File:Eliza face (KK).jpg|thumb|The Landlord's secret.]]
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 leave calmly, but after stamping on what she believes to be a cockroach, is consumed by a swarm of the insects. Eliza glows with light as she absorbs Shireen's life energy. 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 that Shireen was taken by the lice; the Doctor confirms that Harry suffered the same fate.

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 high pitched sounds, such as the sound of her music box; so when he checked on her the next morning, he found that her wooden transformation was beginning, but her illness was cured. Bill then notes the oddity of it; why would a father spend time looking for insects in the garden?

The Doctor congratulates Bill on her quick thinking, remarking that he forgot that humans don't live long, so if the father preserved his daughter seventy years ago, he couldn't still be alive. Eliza becomes confused, as the Doctor explains that her memories have decayed due to the transformation process and the passage of time. The Landlord is actually her son, who did whatever he could to keep his mother alive. Prompted by the Doctor, Eliza realises that her son has committed atrocities throughout his life just to keep her alive in an inhuman condition. She asks her son to let her die, but he refuses and summons the insects to consume the Doctor and Bill. With the Doctor's encouragement, Eliza realises that she can control the insects, and thanking the Doctor for his help, has the insects devour herself and her son.

Without Eliza to act as the linchpin, the house begins crumbling. As they are about to run from the room, Bill sees Shireen remerging from a swarm of the insects on the floor. Bill is overjoyed and hugs her friend, as the Doctor explains that Eliza has restored and released the most recent victims. Everyone runs outside, just in time to watch the house crumble. His work done, the Doctor tells the group to go back to the estate agents; he heads for the TARDIS as Bill and the others gape at the sight of the destroyed house.

[[File:Nardole checks Vault (KK).jpg|left|thumb|Nardole checks on the prisoner]]
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 ''Für Elise'' play on 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|thumb|This episode's ''Aftershow'' on ''[[Doctor Who: The Fan Show]]''.]]
* A working title for this episode was ''The Haunted Hub.''<ref>http://thedoctorwhocompanion.com/2016/10/09/classic-doctor-who-writer-working-on-series-10-episode-title-revealed/</ref>
* [[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 [[Dryad]]s come crawling all over [[John (Knock Knock)|the Landlord]].
* In an interview for ''[[Doctor Who Magazine]]'' [[DWM 512|#512]], writer [[Mike Bartlett]] indicated that [[Harry (Knock Knock)|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 being 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 (TV story)|Blink]]'' - in which a character also referred to the place as "Scooby-Doo's House".
