Silence in the Library (TV story)

"Count the Shadows"

- Node

Synopsis
One hundred years ago, the universe's greatest library was sealed off, leaving only one warning: "Count the shadows". But now, the shadows are moving again. The Doctor and Donna must uncover the terrible truth behind the Nodes and the horrifying Data Ghost, to find the library's secret, and on the way they try to avoid the Vashta Nerada, piranhas of the air, shadows that melt the flesh.

Plot
A little girl seems to be going through a thereputic session with psychologist named Dr. Moon. She reveals that she has a Library, a whole world, which she sees whenever she closes her eyes. She is interrupted by the Doctor and Donna, who had landed on the planet earlier only to have found the world abandoned. The Library is a world, with every every written, powered by the most powerful computer ever. The Doctor recieved a distress call on his psychic paper, but cannot understand why. Although the Doctor had found 1 Million, Million lifeforms on the planet, it appears to be empty. After hearing an eerie message on a Node (a computer with a human's donated face), telling them to run from the shadows, they later have to run from lights that had suddenly started shutting off and come across an orb, seemingly controlled by the girl shown in the beginning.

The Doctor and Donna arrive in the 51st century at a planet-sized book repository simply called "The Library" due to some unknown request for help on the Doctor's psychic paper. However, they find it completely devoid of humanoid life, though the Library's computers claim over "a million million lifeforms" exist. They find a Node, a statue with a strangely realistic human face, that warns them of the shadows, and the Doctor quickly urges Donna to race through the Library stacks as the lights go out behind them, leading them to a central room that is well lit. As they try to figure out more about the warning about the shadows, a team of explorers, led by archeologist Professor River Song, enter the room. Prof. Song explains that she is there with Mr. Strackman Lux, whose family had built the Library, and is there to learn why the Library was sealed for the last one hundred years.

The Doctor quickly organises the team to make sure the area is well lit as he explains that the shadows are occupied by the Vashta Nerada, microscopic carnivorous creatures that use shadows to hunt and latch onto their prey. The team works to find a way out of the library. However, Mr. Lux's assistant, Ms. Evangelista, wanders off and falls prey to the Vashta Nerada, her body eaten away in seconds. The Doctor and Donna learn that the exploration team each wears a communication device which has a glitch called "Data Ghosting" where a copy of a person's consciousness is temporarily held within it for a short time after death, allowing them to communicate briefly with the living.

Throughout their investigation, there are three additional mysteries that develop. First, Dr. Song appears to know the Doctor, though from some point in his own personal future. She carries a diary that seems to be about the Doctor's life with a cover that looks like his TARDIS, and she possesses a more rugged version of the Doctor's sonic screwdriver, but refuses to reveal the future to the Doctor for fear of "spoilers". Also, when the Doctor mentions Donnas name she knows her surname and seems shocked that its her, when Donna asks her if she travelled with the Doctor then why doesent she know her River goes silent. Second, the Library's operations seem to be tied to the imagination of a 21st century young girl, as if she were the world's supercomputer but had just forgotten it, she sees them through the eyes of a security camera when they first break into central room, they appear on her television as the Doctor attempts to hack the Library computers, and when she fiddles with the television's remote, she causes events to occur in the Library. The girl is under observation from Dr. Moon, a child psychologist, at the request of her dad, but Dr. Moon appears to have significant knowledge of the situation of the Doctor, Donna, and the exploration team. He reveals that her reality is an illusion, that her nightmares are reality, and that only she can save all the people trapped in the Library. The final mystery appears to be the word "CAL" that appears at times on the Library screens, the Doctor wondering who or what that means.

The team's investigation is interrupted when the pilot Dave becomes latched to a shadow of Vashta Nerada, and though the Doctor attempts to save him, he is quickly eaten away, the organisms taking control of his suit. Dave's Data Ghost echoes his last thoughts as the suit approaches the rest of the team. The Doctor attempts to teleport Donna back to the TARDIS while he leads the rest of the team to safety, but something goes wrong in the teleport and Donna fails to materialize properly. As the team races away from the possessed suit, the Doctor is horrified to find a Node with Donna's face on it, which claims that Donna has left the Library and has been "saved". A statement the little girl is seen saying earlier.

The show ends in a cliffhanger as the Doctor is forced to leave the Node behind, and run with the team from the approaching Vashta Nerada.

Story notes

 * Transmission of this episode was delayed by one week due to the Eurovision Song Contest, as was the case last year with a gap between The Lazarus Experiment and 42.
 * According to Russell T Davies this episode is more frightening than Steven Moffat's series 3 episode Blink, which rated a 5.5 out of 5 on the the official Doctor Who website 'Fear Factor' feature.
 * While the Doctor is hacking into Eve's TVv she is watching the CBBC show Pedro and Frankesheep which makes it the second time in this series someone has been watching a real-life kids show after The Doctor watching Tommy Zoom in The Poison Sky and the third since the series revival.
 * Professor River Song mentions having "been to the End of the Universe" with the Doctor.
 * Excluding the Children in Need specials, this is the 50th episode of Doctor Who since the series returned in 2005.


 * Steve Pemberton is the second of the League of Gentlemen to appear in Doctor Who, the other being Mark Gatiss who appeared in The Lazarus Experiment as Richard Lazarus.


 * 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.

Myths

 * The walls of The Girl's home are decorated with a pattern suggesting trees in a forest, possibly referred to by the next episodes's title.

Filming Locations

 * The main library scenes for the episode were filmed at Swansea Library and Brangwyn Hall, Swansea.

Discontinuity, Plot Holes, Errors

 * When standing on the balcony upon entrance, The Doctor remarks on how, being near the equator, they must be in or near the Biography section, though when the screen pans down, a Traffic sign can bee seen with a marking to the left with the Words "Xeno Biology". It also had "Art" underneath it, both with arrows pointing to the left. This is probably just an indicator on where to find those sections.
 * At the beginning when we see the Doctor and Donna enter the room from the little girl's point of view we see the door is kicked multiplied times before they enter however when we see it from the Doctor and Donna's point of view we see Donna kicks it once before entering.(The rest may have been the doctors attempts to get in)
 * The keyboards on the computer terminals in the library are, in fact, the latest incarnation of Apple Computer's USB keyboard. Stock investors take note - Apple computer will be manufacturing hardware for at least another 3000 years.

Continuity

 * A similar species which could take over the light but weren't hostile were the Cimmerians in the BFA: Embrace the Darkness.


 * 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 (DW: Destiny of the Daleks), The French Revolution (DW: An Unearthly Child), the Journal of Impossible Things (DW: Human Nature (TV story)/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 (DW: The Creature from the Pit) and Black Orchid (a book first seen in the Fifth Doctor serial DW: of the same name).
 * The Doctor makes mention of 'Emergency Program One' which would return Donna home, this was first seen and used in DW: The Parting of the Ways.
 * The last time the Doctor received a message on his psychic paper was in DW: New Earth.
 * This is the second time the Doctor has arrived 'too early' (or rather the TARDIS has brought him too early), this previously occured in DW: The Doctor's Daughter.


 * The Doctor recieves a message on the phsycic paper which shows up and he shows it to Donna. Donna takes it from him and shows it to him but it is now blank. It is possible that as the message passes out of sight of the viewer, it fades.

DVD and other releases

 * It will be released on the Series 4 boxset DVD in November 2008.
