The Shakespeare Code was the second episode of the third series of Doctor Who. It included the first televised appearance of William Shakespeare since a cameo in 1965's The Chase.

Gareth Roberts was well known as a fan of Shakespeare; he had included him as a character in A Groatsworth of Wit, a Ninth Doctor comic strip. The Carrionites were also derived from the Bard's work, specifically the witches in Macbeth.

Code was one of the most costly stories ever produced, with large expenditures on costumes and sets. Some of the expense was quickly rationalised by BBC Wales, however. The interior of the witches' house was almost immediately reused as Sarah Jane's attic at 13 Bannerman Road, where its expense was amortised over the five-year run of The Sarah Jane Adventures. (DWMSE 23)

Synopsis

As a reward for her help in the last episode, Martha Jones gets a trip in the TARDIS. The Tenth Doctor takes her to 1599 England. After viewing a performance of Shakespeare's latest play, the time travellers are beset by apparent sorcery. Under threat of annihilation from a species from the Dark Times, the TARDIS team have to establish whether there is a connection between a witch they've met and Shakespeare's Love's Labour's Won — a play that was legendarily lost to time.

Plot

A nymph, Lilith, is serenaded from her balcony by a lute-playing swain, Wiggins. She bids him enter, much to his delight. However, upon entering her home, he is shocked to find it full of horrifying witching artefacts — not what he would expect a beautiful girl to have in her home. Lilith kisses Wiggins, but on pulling away, he finds her transformed into a wrinkled hag. She decides to introduce her suitor to her two "mothers", Mother Doomfinger and Mother Bloodtide. Much to Wiggins' horror, the two mothers cackle and pounce on him, apparently devouring him. Lilith cackles and states that at the hour of spoken words, they will be freed and the Earth will perish.

Meanwhile, the TARDIS has just landed nearby. Martha Jones steps outside and is amazed by the fact they've gone back in time. Martha questions when they are, but the Doctor quickly pulls Martha back, keeping her from being struck by the contents of a chamber pot. The Doctor tells her it's "before the invention of the toilet", apologising. However, Martha takes the event in stride as she has seen worse things in hospital. She then questions whether it is safe to walk around in the past, citing familiar time travel paradoxes such as the grandfather paradox and the so-called "butterfly effect". She frets over her reception as a black woman in a time when slavery still exists. The Doctor points out that he's not even human and to walk around like "you own the place", just as he does.

They walk around the town and the Doctor says Elizabethan England is far more like the 21st century than she might think. He points out there are things similar to the future. The Doctor deduces both their location and the year: near the Globe Theatre in 1599. The Doctor tells Martha when she gets home, she can tell everyone she's seen Shakespeare. However, Martha gleefully and sarcastically retorts that she would get sectioned.

The Doctor and Martha attend Love's Labours Lost.

At the Globe, Love's Labour's Lost is on. Martha tells the Doctor how much she loved the play before pointing out that the male actors are dressed as women. The Doctor jokes, "London never changes". Wanting to see the author himself, Martha starts what the Doctor thinks might be the first crowd chant for Shakespeare. The author himself comes on stage with the crowd cheering; he's quite a bit different from his portraits. The Doctor goes on about how much he admires Shakespeare's genius. However, the Doctor turns out to be wrong about the consistency of the Bard's genius when he asks the audience to shut their "big fat mouths". Martha tells the Doctor he shouldn't meet his heroes.

Shakespeare then announces there will soon be a sequel, Love's Labour's Won. Lilith, using the influence of a poppet, influences the great writer to rashly promise that the yet unfinished play will premiere tomorrow evening. Martha asks why she has never heard of Love's Labour's Won. The Doctor knows of the lost play as it appears in the listing of Shakespeare's works, but the play itself is non-existent. He decides to find out more about why it was never published.

At the inn where William Shakespeare is staying, the writer is discussing the announcement of his play with the actors, who are curious as to why he announced the play for tomorrow instead of next week as they planned. He will have the last scene finished by the morning. The Doctor enters and Shakespeare tells him to leave. He says he won't give him an autograph or a portrait done with him. He adds that the Doctor not ask him where he gets his ideas. Upon seeing Martha enter, he stops dead. Recognising the signs, the actors excuse themselves; to them, it looks like Shakespeare has found a new muse. Shakespeare is confused by Martha's clothing and the Doctor explains she's from "Freedonia".

The Doctor fails to trick Shakespeare with the psychic paper

Upon trying to pass himself off as "Sir Doctor of TARDIS" via the psychic paper, the Doctor is shocked to find that Shakespeare sees it as blank. Martha is confused by this as she sees the Doctor's title on the paper. Shakespeare remains adamant about what he sees and the Doctor explains the psychic paper, noting that Shakespeare's immunity to the paper proves the writer is an "absolute genius". The writer takes interest in the word and wonders who the Doctor is. However, his attention shifts to Martha, whom he tries wooing, describing her as "a queen of Afric" or a "blackamoor lady", which she finds slightly offensive. The Doctor says it's "political correctness gone mad".

At that moment, Lynley, Master of the Revels, barges in, demanding to see the script before he allows the play to proceed. When Shakespeare offers to show him the finished script in the morning, the official leaves, proclaiming that this slight means he will ensure the play will never be performed, even if it's the last thing he does. The Doctor assumes that this explains why Love's Labour's Won was never shown.

Lynley drowns via Lilith's "witchcraft".

Lilith, who works at the inn, overhears this and secretly takes some of Lynley's hair which she adds to a doll. She contacts her mothers, who chant with her, using the doll to control Lynley. Lilith plunges it into a bucket of water. The Doctor, Martha and Shakespeare hear a commotion in the street and run out, where Lynley vomits water. Lilith stabs the doll in the chest, and Lynley collapses, dead.

Martha and the Doctor try helping him, but are shocked to find his lungs full of water. The Doctor calmly announces to the crowd that Lynley died a natural death, of an sudden imbalance of the humours. Confused, Martha asks the Doctor why he told the crowd a lie. The Doctor whispers that they've got "one foot in the Dark Ages", and any seemingly unnatural answer would lead them to think that it was witchcraft. When Martha asks what actually killed Lynley, the Doctor responds, "witchcraft", confusing her further.

Inside, they wonder about Lynley's murder, but Shakespeare is equally confused by Martha's training as a doctor, wondering what kind of land Freedonia is. Martha defends herself by saying in Freedonia, women can have any profession they want. He then asks the Doctor how he can have eyes so old for someone young. The Doctor says it because he reads a lot. Shakespeare sees it's a trite reply, something he'd do himself. He then notes Martha looks at the Doctor like she's surprised he even exists.

The Doctor and Martha have been informed by the landlady that she's prepared a room for them. Shakespeare explains he still has to finish writing the end of the play and bids the Doctor good-night, saying he will solve why the constant performance from him tomorrow. The Doctor then gives Shakespeare his "All the world's a stage" line before retiring for the night.

The Doctor and Martha spend the night.

Martha is less than impressed with the room, complaining she doesn't even have a toothbrush. The Doctor gives her one from one of his pockets, explaining it contains Venusian spearmint. Martha begins to wonder if magic exists as well before the Doctor of course it doesn't — this looks like magic but is not. She complains that she just started believing in time travel and he should give her a break. The Doctor gives a disgruntled Martha mixed signals by casually sharing the bed with her only to show no interest, then dismissing the idea that a mere human could be channelling the psychic energy and bemoaning the lack of Rose's insight. However, without seeming to notice Martha's reaction, he attributes this to Martha being a novice to time travel. He says he'll take her back home tomorrow.

Meanwhile, Lilith entrances Shakespeare and, using a marionette, compels him to write a strange concluding paragraph to Love's Labour's Won. She is discovered by the landlady, whom she frightens to death with her true form. Upon hearing another scream, the Doctor and Martha run in to find her body as Shakespeare wakes. Through the window, Martha sees Lilith flying away on a broomstick. When asked by the Doctor what she saw, Martha answers, "A witch".

In the morning the Doctor, Martha and Shakespeare are confused by what has happened. Correctly guessing that Shakespeare is central to the witch's plot, Martha accidentally tells Shakespeare he will write about witches. Shakespeare then remembers Peter Streete spoke of witches; he was the architect for the Globe Theatre. This leads the Doctor to investigate the Globe next. There, he wonders why the theatre is tetradecagal. The Doctor thinks he's heard of something before that involves the number 14, but can't seem to remember it.

A Carrionite spectre appears at the rehearsal.

Upon his companions' opinions of what has the number 14 in it, the Doctor asks why the Globe was designed like this. Shakespeare explains the architect thought it allowed the sound to carry well. When questioned as to the whereabouts of Peter Streete, Shakespeare says that he was admitted to Bedlam. The Doctor decides that is their next stop. Shakespeare follows after him after giving his actors the final draft of his play.

Once at Bedlam, Martha and the Doctor are disgusted to learn that the patients are whipped to entertain the gentry. Shakespeare defends it, saying that fear of the place helped "set him right". The Doctor explains that Shakespeare fell into depression after his son's death. Shakespeare then speaks, "To be or not to be", from his future play when explaining what he felt then, but wonders if the line is a bit pretentious; the Doctor is indifferent about it. They are led into Streete's cell, where the Doctor finds he is suffering from catatonia.

Lilith senses this and, along with her mothers, sees the Doctor in their cauldron. She remembers him from the previous night and wonders why he now visits the madhouse with Shakespeare. The Doctor smells of something new to them. Fearing that they be revealed, Lilith has Doomfinger transport herself.

In the cell, the Doctor uses his telepathy to help Peter overcome his condition long enough to help explain what he went through. On the Doctor's order, Streete reveals that witches spoke to him and made him design the Globe to their design, not his own. He also tells the Doctor that the witches were based in All Hallows Street.

The Doctor, Martha and Shakespeare meet Doomfinger.

Immediately, Mother Doomfinger appears in the cell and kills Peter with a touch. She threatens the others and the Doctor steps forward to confront her. He then begins rambling about the facts: humanoid females that channel energy into power through words. The Doctor figures out that the 14 walls of the Globe are based on the 14 stars of the Rexel configuration. He then names Doomfinger a Carrionite, which causes her to disappear. The Doctor explains the Carrionites produce their "magic" through an ancient science based on the power of words.

Back at the Elephant, the Doctor explains that Carrionites vanished at the dawn of the universe. However, its seems some of them are back. How they managed to get back is quickly figured out by Martha and the Doctor. They planned on using Shakespeare and his brilliant words to bring the rest of their species back; "Love's Labour's Won is a weapon!" The Doctor tells Shakespeare to stop the show whilst he and Martha go to All Hallows Street to thwart the witches.

Shakespeare bursts on to the Globe's stage to make the announcement, but two of the Carrionites are already there and use one of their dolls to render him unconscious. The actors — thinking Shakespeare has passed out drunk — carry the playwright offstage and the performance proceeds after they apologise to the crowd.

The Doctor confronts Lilith.

The Doctor and Martha reach All Hallows Street and pause for the Doctor to explain the reality of the danger. They confront Lilith, who is expecting them. She confirms the Doctor's suspicions: the three Carrionites hope to gain entry for the rest of their species, eliminate the humans, begin a new empire on Earth and spread out from there. Martha, mimicking the Doctor's actions at Bedlam, tries to neutralise her by speaking the name Carrionite, but Lilith mocks her, since naming only works once. Instead, she names Martha Jones, rendering her unconscious, muttering that she was unable to harm her more, as she must be out of her own time. Lilith tries to do the same to the Doctor, but fails, as her psychic power is unable to uncover his real name. She senses a name that could hurt him and tries to weaken him by naming "Rose", but he assures her that that name keeps him fighting and demands to know how the Carrionites came to be on Earth.

Lilith explains the Eternals found the correct word to banish the Carrionites into darkness, but the three were able to escape using the power of Shakespeare's grief over his son — the grief of a genius — and intend to free the others. She approaches seductively, which the Doctor says definitely won't work on him, and then quickly cuts a lock of his hair. Taking flight through the window, she attaches the hair to a doll — which the Doctor says is basically a DNA replication module — and stabs it in the heart. The Doctor collapses, making Lilith think he's dead. She flies to the Globe, leaving them behind. Martha awakens, thinking the Doctor is dead as well, but finds he's still alive — two hearts. With her help, the Doctor manages to re-start his other heart. They proceed to the Globe to stop the Carronites.

However, at the Globe, the actors have already spoken the last lines of the play. Much to the horror of the audience, Carronites emerge from a crystal held by the three and swarm outside. The Doctor and Martha arrive to find Shakespeare regaining consciousness and rubbing his head in pain. After making a joke about his eventual balding, the Doctor goes on stage to try undoing the damage, but finds only William can.

Loves Labours Won is lost, as are the Carrionites.

Joining the Doctor, Shakespeare is told to improvise a verse to get rid of the Carronites. The Carrointes in the theatre wither in fear of his words, but William gets stuck on the last one, unable to think of a rhyme. Martha comes up with "Expelliarmus" (a magic word coined by author J.K. Rowling in her Harry Potter books) and the Carrionites — together with all the extant copies of Love's Labour's Won — are sucked through the portal. Martha, Shakespeare and the actors are left to take the applause of the audience who thought it was special effects. The Doctor finds the three "witches" trapped, screaming in their own crystal ball, and decides to keep it in a "dark attic" of the TARDIS.

The Queen sees her "sworn enemy"

In the morning, Shakespeare flirts once more with Martha...and with the Doctor. He reveals his deduction that the Doctor is not of the Earth and that Martha is from the future. For his "Dark Lady", he produces the sonnet, "Shall I compare thee to a summer's day?" in her honour, but is interrupted when two of his actors burst in, heralding the arrival of the Queen, who wants to see the play from last night. Queen Elizabeth enters, much to the Doctor's amusement. However, it seems they have met before in her past; he is deemed her "sworn enemy". The Queen declares, "Off with his head!"

This shocks the Doctor as he has yet to meet her, but comments that he is looking forward to finding out what he will do to offend her. He is then forced to run by Martha to keep himself alive. They run through the streets back to the TARDIS as the guards run after them. They enter the TARDIS, slamming the door just as an arrow embeds itself in the TARDIS' exterior before dematerialisation.

References

  • Psychic paper doesn't work on Shakespeare. This is apparently proof he is a genius.
  • The Carrionites have several similarities to the Shadeys who were also involved with Shakespeare at one point.

Culture

  • There are numerous Harry Potter mentions and references - "Expelliarmus", as well as "Wait till you read book seven, I cried." (The episode was broadcast roughly three months before the book was released.) David Tennant also had a role in the fourth Harry Potter film.
  • Martha asks about accidentally stepping on butterflies when questioning the Doctor about the repercussions of time travel. This is a reference to the short story A Sound of Thunder by Ray Bradbury, in which a man travels back in time and accidentally steps on a butterfly, resulting in history changing.
  • Martha references the Grandfather Paradox, most famously dated back to the 1944 story Le Voyageur Imprudent by René Barjavel, although the concept is mentioned in passing in a 1929 tale by Cloukey called Paradox.[1]
  • The Doctor uses the 1980s film Back to the Future to explain the mechanics of the infinite temporal flux in relation to time travel to Martha.
  • The Doctor quotes a line from Dylan Thomas' poem "Do Not Go Gentle Into That Good Night" ("Rage, Rage against the dying of the light."), before telling Shakespeare he can't use it.
  • In attempting to explain Martha to Shakespeare, the Doctor claims that she comes from Freedonia, a fictional country featured in the Marx Brothers film Duck Soup.
  • Near the climax, the Doctor admonishes Shakespeare that "We can have a good flirt later." Shakespeare coyly replies, "Is that a promise?", to which a stunned Doctor says, "And 57 academics just punched the air!" This is a reference to sonnet 57, a sonnet of Shakespeare's in which he expressed his love for another man. Current academic theories that claim that many of Shakespeare's sonnets were penned as love sonnets to a man, and that Shakespeare himself was either bisexual or homosexual.
  • Shakespeare's attraction to Martha and referring to her as "The Dark Lady" seem to be references to Shakespeare's purported lust for black women, also referenced in Anthony Burgess' novel Nothing Like the Sun.
  • The Carrionite Lilith's name derives from a Succubus who would visit men in their sleep. In this case Lilith was placing ideas into Shakespeare's mind in order to bring more Carrionites through. But in many cultures these night time visits brought others of her kind through by a more primal route.
  • Shakespeare ends up uttering a quote he will use later in Hamlet ("To be or not to be...."). Centuries later, the Royal Shakespeare Company will put on Hamlet (Starring Sir Patric Stewart) and none other than David Tennant (as Hamlet) will utter those same lines in his famous soliloquy.

Story notes

  • The episode bears some similarities to the previous Gareth Roberts' penned comic story featuring Shakespeare and the Ninth Doctor, A Groatsworth of Wit, which may have provided some of the inspiration for this episode.
  • The title appears to be a play on The Da Vinci Code, which is also a story based around a well-known figure of the Renaissance.
  • This was the second appearance of a famous writer in the revived series, the first being Charles Dickens in TV: The Unquiet Dead.
  • This episode's working titles were Theatre of Doom and Love's Labours Won.
  • Freedonia is a fictional country from the comedy film Duck Soup.
  • Shakespeare did use the word Sycorax in his play The Tempest.
  • Shakespeare referred to Martha as the "Dark Lady," the mysterious subject (though perhaps allegorical) of many of his sonnets.
  • The story plays on the speculation around Shakespeare's Love's Labour's Won, a possible "lost play" or alternate title for an existent play.
  • Lilith's name is only said once throughout the whole episode. It is only said in the beginning when the young man tells Lilith that her house is foul. Her name is not even said by Bloodtide, Doomfinger or Lilith herself.
