Silence in the Library (TV story)

Silence in the Library was the eighth episode of the fourth series of Doctor Who. It marked the first appearance of River Song, a mysterious person with an important role in the Doctor's personal future. The enemy of the episode is once again created by Steven Moffat by using the childish fear of the dark — Vashta Nerada.

Donna's departure at the end of the series is hinted at in this episode. River reacts upon learning who Donna is, but refuses to answer why she doesn't know her in the future despite knowing the Doctor.

Synopsis
The Tenth Doctor takes Donna Noble to a planet-sized library in the 51st century. They find it empty of human life, with a final recorded message: "4,022 saved, no survivors." As an archaeological expedition arrives, lead by the mysterious Professor River Song, they can only give one piece of advice: count the shadows.

Plot
A little girl is in a session with her psychologist, Doctor Moon. She says she has a library, a whole world, which she sees whenever she closes her eyes. It is a peaceful place, entirely empty of human life. Suddenly, the world she sees is interrupted by loud pounding on a locked door. As the door bursts open, two mysterious strangers rush in – the Tenth Doctor and Donna Noble...

In the TARDIS, the Doctor and Donna arrive in the 51st century on a planet-sized book repository called simply "the Library". It is an entire world, holding every book ever written, and powered by the most powerful computer ever. Shortly after arriving, they realise however that the Library is completely empty. The Library's computers confirms that they are the only humanoid life on present, but it then claims there are over "a million million lifeforms" in the Library. Donna asks why they really came here, and the Doctor admits that he earlier received a message for help on his psychic paper. He doesn't know who it's from, but Donna observes that it was signed with a kiss. Nearby, a statue with a strangely realistic human face, called a Node, warns them to count the shadows... Donna is shocked to find that the faces are selected by the Nodes from those which have been "donated" by the deceased. Just then, the lights begin to go out around them. Wary of the warning regarding shadows, they race through the Library aisles until they reach a well lit room. The doors are locked, but Donna kicks them open.

There they see a football-shaped security camera hovering in the air. In her living room, the little girl opens her eyes at the same moment the camera shuts itself down. The Doctor scans the camera with his sonic screwdriver. The girl screams, terrified by the sound of the sonic screwdriver inside her head. The camera sends the Doctor a message that begs him to stop the noise, which he does. The camera and the girl both warn that "others" are coming; the Library has "been breached". The door opens, and a team of explorers in spacesuits enter. The leader walks up to the Doctor and greets him, "Hello, sweetie." As the Doctor tells them all to leave immediately, the leader introduces herself as an archaeologist named Professor River Song. She acts very familiar with the Doctor, but he does not know her. Professor Song explains that her team are there with Mr Strackman Lux, whose family built the Library, to learn why it has been sealed for the last hundred years.



The Doctor quickly organises the team to make sure the area is well lit. He says the shadows are occupied by the Vashta Nerada, microscopic, carnivorous creatures which use shadows to hunt and latch onto their prey. The team work to find a way out of the Library. River Song calls the Doctor over in private, where she merrily opens a diary with a cover that looks like the Doctor's TARDIS. It seems to be about his life. She tries to find out in which part of the Doctor life she's in, but realises he is so young he does not know her. From his perspective, this is the first time they have met. She, on the other hand, seems to know him well.

One of the team activates one of the computer systems, and causes a steadily repeated sound exactly like a ringing phone. At the same moment, the girl hears the phone in her house ringing, although her father doesn't. She hesitates to answer and the phone stops ringing. The Doctor hacks into the computer. The young girl then sees the Doctor and the team on her television, replacing the cartoon she was watching. A disturbance occurs and the Doctor loses the image of the girl. As he hacks into the computer, he sees River Song's diary and moves to pick it up. River Song stops him, saying it's against the rules - his rules.

The girl fiddles with the television's remote. Books fly into the air from the shelves in the Library. Donna calms Mr Lux's assistant, Miss Evangelista. The word "CAL" appears at times on the Library screens. The Doctor asks Mr Lux about it. Mr Lux refuses to help, claiming that he is protecting his family's pride. The Doctor berates him and tells him that the team is in grave danger.

Miss Evangelista sees a secret door when the girl pushed a random button from the remote. She tries to tell the others, but they don't listen. She wanders off and is quickly killed by the Vashta Nerada. The team find Miss Evangelista's skeleton. The communication device worn by the exploration team allows for a glitch called "Data Ghosting"; a copy of a person's consciousness can be temporarily held in it for a short time after death, allowing them to communicate briefly with the living. Miss Evangelista speaks briefly to the "kind woman", Donna, just before her consciousness is lost. As the team listens on sadly, her last words,"ice cream", are repeated.

Dr Moon, the child's psychologist, asks to speak to her alone before he leaves. He asks if she knows the difference between dreams and reality. She says that of course she does. He tells her that her reality is an illusion; her nightmares are the true reality, and only she can save all the people trapped in the Library.

The Doctor proves the Vashta Nerada's existence by throwing a chicken leg from River Song's lunchbox into the "shadow". The chicken leg is eaten to the bone instantly. When he mentions Donna's name, River Song recognises it. Her reaction seems to be a mixture of shock and sadness. Donna asks where she is in this future when River knows the Doctor. River goes silent. The team's investigation is interrupted when the pilot, "Proper Dave" — in contrast with the other "Dave" — acquires an extra shadow. The Vashta Nerada have attached themselves to him. The Doctor orders everyone's helmet on, as it might slow down the Vashta Nerada a bit. He also finds that River Song possesses a more advanced version of his sonic screwdriver, which she claims was a gift from him.

As Donna does not have a spacesuit for protection, the Doctor teleports her back to the TARDIS. He cannot send the others, because the TARDIS wouldn't recognise them. Over Donna's objection, he stays behind to lead the rest of the team to safety. As Donna begins to materialise in the TARDIS control room, something unexpectedly interrupts the process, and she disappears again. Meanwhile, the Doctor attempts to save proper Dave, but Dave is quickly eaten away. As proper Dave's data ghost echoes his last thoughts ("Hey, who turned out the lights?"), the organisms take control of his suit and approach the rest of the group. River uses a sonic blaster to make a hole in the wall, and they race away from the possessed suit. They run down a dead-end hallway as the suit approaches. The Doctor is further concerned that he has not yet received a signal from the TARDIS letting him know that Donna arrived safely. As a nearby Node turns around, he is horrified to find it with Donna's face on it. It states that Donna has left the Library and has been "saved"...

Cultural references from the real world

 * When he and Donna arrive at the Library, the Doctor makes reference to author Jeffrey Archer, the Bridget Jones franchise, and Monty Python's Big Red Book.
 * A model of Robby the Robot is visible in the young girl's home.
 * The relationship between the Tenth Doctor and River Song is similar to the novel  by . That story is about a man who travels in time, so that the first time he meets his partner she has already met him before. That meeting also occurs in a library, and, like River Song, she gives him a diary of their time together.
 * The girl watches  on her television. When she changes channels (causing the books to fly around in the Library) a brief snippet of dialogue from an episode of Ren and Stimpy can be heard.
 * On the little girl's wall are two drawings: a blond and a wolf.

Locations

 * River and the Doctor will share/have shared a picnic at Asgard.
 * River mentions having "been to the End of the Universe" with the Doctor.

Species

 * Vashta Nerada are said to exist on a billion worlds, including Earth, but in small numbers and mainly feeding on road-kill.

Technology

 * The Doctor notices (and says so) that River Song has a squareness gun.
 * The Doctor receives a message from River Song on his psychic paper.
 * The Doctor uses a teleport to attempt to send Donna to the TARDIS, but mentions that he could only do this for Donna as the TARDIS wouldn't recognise the others.
 * The sonic screwdriver doesn't work on wood. Some very strong signals and certain types of hairdryers can interfere with it.
 * The Doctor recommends that a quarantine beacon be placed around the Library.

Story notes

 * Transmission of this episode was delayed by one week due to the Eurovision Song Contest, as was the case with the Series 3 gap between The Lazarus Experiment and 42.
 * Russell T Davies feels this episode is more frightening than Steven Moffat's series 3 episode Blink, which rated a 5.5 out of 5 on the official Doctor Who website 'Fear Factor' feature.
 * While the Doctor is hacking into the girl's TV, she is watching the CBBC show Pedro and Frankesheep. Previous real-life kids shows whose clips have been shown on Doctor Who include the Doctor watching Tommy Zoom in The Poison Sky, the Master watching The Teletubbies in The Sound of Drums, and the Master (again) watching The Clangers in The Sea Devils.
 * Excluding the Children in Need specials, this is the 50th episode of Doctor Who since the series returned in 2005.
 * When the girl collapses due to the Doctor's tampering with the security camera, the pattern of the rug she collapses on is the same as the red pattern on the computer screens reading "Access Denied". It also can be briefly seen on the lens cap of the security camera, and repeated in the metalwork in the background of the circular room much of the library scenes take place in.
 * Additionally, when Doctor Moon and her father rush to her side when she collapses, a plastic tag reading "CAL" can be briefly seen on Doctor Moon's briefcase.
 * The security camera appears to have angel wings carved on its sides.
 * Steven Moffat continues his theme of highlighting childhood fears: in Blink, it was statues coming to life; in The Girl in the Fireplace, it was monsters under the bed; and in The Empty Child/The Doctor Dances, it was the fear of war and bombardment.
 * The spoilers theme may be an in-joke about DW spoilers (especially online). Additionally, the word "spoilers" is said twice in rapid succession in the trailer for the next episode, which may be a comment on the nature of the trailers themselves.
 * There is, perhaps, unintentional irony to the Doctor's line, "No, I never land on Sundays. Sundays are boring." Given that Saturdays are "good", according to The Stolen Earth, it could also be a reference to the fact that the day after a new episode of Doctor Who is broadcast is comparatively boring. Former companion Ace also once mentioned that she found Sundays boring in Survival. In PROSE: Wetworld, the planet that he and Martha visited was called Sunday.
 * The Library's front desk looks like a redecorated version of a control console from The Sontaran Stratagem/The Poison Sky or the teleport control unit from Voyage of the Damned.
 * In the associated Doctor Who Confidential episode, Steven Moffat says that he imagined River found the gun (as left behind by Jack) in the TARDIS during her future travels.
 * Steven Moffat stated that British newspaper The Sun got a hold of the script for the episode and threatened to publish it. Moffat jokingly told them to do it; he later remarked, "I'd like to see The Sun publish that many words in a day."
 * The previous episode ended with the Doctor showing a traditional paper-bound book dating from the far future, a thematic lead-in to this visit to the Library (although dialogue indicates that he and Donna were originally travelling elsewhere).
 * As shown on the BBC Doctor Who website, there are a number of books in the library that reference previous episodes. Those seen are the operating manual for the TARDIS, Origins of the Universe, (TV: Destiny of the Daleks) The French Revolution, (TV: An Unearthly Child) A Journal of Impossible Things, (TV: Human Nature/The Family of Blood) The Hitchhiker's Guide to the Galaxy (written by Douglas Adams, former Doctor Who writer and script editor), Everest in Easy Stages, (TV: The Creature from the Pit) and Black Orchid (TV: Black Orchid).
 * The story also has considerable commonality with a Fifth Doctor illustrated text story, Catalogue of Events, from the 1983 Doctor Who Magazine Special.

Myths and rumours

 * The mystery of River Song led to much online fan speculation over her identity. Possibilities cited ranged from River being an iteration of Bernice Summerfield (as the two share similar personalities and are both space archaeologists) to a disguised Time Lord like Romana. Additional ideas abound. In TV: A Good Man Goes to War, it was revealed she wasn't an older character, but the human (with Time Lord DNA) daughter of Amy Pond and Rory Williams.
 * Evangelista's last words have occasionally been misinterpreted as "I scream." On the official BBC subtitling, her final words are, "I... Ice cream. Ice cream," which is in keeping with her (initially) childlike demeanour.

Production errors

 * After River Song greets the Doctor with "Hello, sweetie", in the next shot of the Doctor, Donna and River, a boom mic is just barely visible in the top left corner above River's head.
 * After the shot in which Proper Dave is seen to have two shadows, there is a short shot from a different camera angle where in the Doctor passes Dave his helmet. In this short shot, Dave is seen to have but one shadow. When the shot returns to the previous camera, Dave has two shadows, as before.
 * When the Doctor and group are talking to the little girl on her TV you can see them all standing around the console but when the shot pulls back and they all back away from the console you can see that half of them have changed positions. Mr Lux, Proper Dave, Anita and Miss Evangelista have all changed from their positions seen on the TV to when you cut to the group. Also Donna who is clearly close to the Doctor's right is not shown leaning to look into the console but jumps back like everyone else as if she had been looking into it.
 * When Miss Evangelista dies then you can see that she had lost one green bar but in a later shot she lost the same bar again.
