The Unicorn and the Wasp (TV story)

From Tardis Wiki, the free Doctor Who reference

The thrill is in the chase, never in the capture.Agatha Christie

Synopsis

In 1926, Agatha Christie mysteriously disappeared, only to be found ten days later, with no memory of what had happened. Was it a nervous breakdown? a cry for help? or perhaps a giant alien wasp..?

Plot

File:TenChristieDonna.jpg
The three sleuths

The Doctor and Donna Noble arrive in time for an afternoon party at the Eddison estate. The event is hosted by Lady Eddison and her husband, Colonel Hugh Curbishley. One of the guests is famed British mystery writer, Agatha Christie. Still a young writer, she has recently published her sixth novel. Looking at a newspaper, the Doctor finds that it is 8th December 1926, the day of Agatha Christie's disappearance. Just as this revelation is made, Eddison's friend and companion Miss Chandrakala finds another guest, Professor Peach, dead in the library . He was murdered with a lead pipe.

At the scene, Donna comments on the similarity to the board game Cluedo. The Doctor finds "morphic residue" on the floor while examining the scene - morphic residue, a by-product of shapeshifting, implies that one of the guests isn't really human. Agatha discreetly removes a fragment of paper from the grate on the fireplace. The Doctor notices but says nothing.

Christie loses faith in her investigative abilities

Aided by Agatha, the Doctor interviews the guests while Donna goes looking for clues. During the interviews, while the guests recount their stories, flashbacks reveal that each is hiding something, except Rev. Arnold Golightly.

Lady Eddison claims to having been taking tea, though she was in fact surreptitiously consuming liquor. Robina Redmond, a socialite, claims to have been using the toilet, but is shown loading a tiny pistol there. Roger Curbishley, Lady Eddison's son, claims to have been walking, alone, failing to disclose he was attending a tryst with his lover, Davenport, who is one of the servants. Colonel Hugh Curbishley claims he was reading military memoirs in the study, though he was actually viewing erotica while fantasizing about can-can dancers.

After the interview, Agatha Christie produces the paper she removed earlier which contains the letters "a-i-d-e-n", preceded by one illegible letter. Agatha points out that it obviously spells the word "Maiden", although neither she nor the Doctor is able to divine the significance of this.

The Unicorn witnesses a murder

When Donna investigates a locked room in which Lady Eddison had sequestered herself, for six months, while allegedly recovering from malaria, she is alarmed by a giant wasp outside the window. Donna uses a magnifying glass to focus the sun's rays on it, injuring it and allowing her to flee. The insect chases her, impaling its stinger on a door.

Davenport is in the kitchen, speculating about why someone would want to kill Professor Peach. Miss Chandrakala is also there, and dismisses this as "dead man's folly" until she suddenly realises exactly what Professor Peach was doing. Rushing off to warn Lady Eddison, she is killed when an unseen figure hurls a gargoyle from a ledge--and hits her head.

Hearing her scream, the Doctor, Agatha, and Donna rush outside; Miss Chandrakala dies on the scene, cryptically offering "The poor little child..." as her last words. Seeing the Vespiform hovering above the building, the Doctor gives chase, but loses the creature in a hall. When the Doctor shouts "show yourself," all of the doors open and every suspect appears.

After the guests pile pressure on Agatha to solve the murder, she retreats to the garden. Donna goes out with her to comfort her, comparing her similar trouble with men, references the events of "The Runaway Bride." Even though Agatha refuses to believe in her own brilliance, she discovers a box filled with the tools of a thief.

While the three mull over the evidence they've gathered thus far, and Donna accidentally gives Agatha the idea for Miss Marple, the Doctor is poisoned with cyanide. While cyanide is always fatal to humans, Time Lords can neutralize the poison and expel it--if they ingest an odd combination of ingredients (ginger beer, proteins (in walnuts), salt (in anchovies, as pure salt is "too salty")) followed by a shock (a kiss from Donna).

Recovered, the Doctor "poisons" the guests' dinner with pepper; naturally, this is not harmful to humans, but is poisonous to wasps. A buzzing sound can be heard moments later, at which Lady Eddison exclaims, "It can't be!" The lights are blown out by a sudden wind and they again fail to ascertain the identity of the alien. Roger, Lady Eddison's son, is murdered in the confusion, and Lady Eddison's necklace, 'The Firestone', is stolen.

The Doctor points an accusatory finger at a suspect

In the sitting room, the Doctor and Agatha reveal several secrets about the guests and hosts. Robina Redmond, one of the guests, is a thief, the titular Unicorn, who coveted the Firestone and stole it in the confusion; however, she is not the killer. The truth of Lady Eddison's bout of malaria is also revealed; she was actually pregnant, and not by another human being. The alien was a Vespiform, and gave her the Firestone necklace. The necklace is psychically linked to their son, whom she had given up for adoption and never seen again: Reverend Golightly.

It was Golightly who killed Professor Peach, when he learned that the Professor had discovered his adoption paperwork. He then attempted to burn the paperwork: the word "Maiden" on the paper Agatha plucked from the grate had in fact said "Maiden Name".

Because Lady Eddison had been reading The Murder of Roger Ackryod when her son's alien biology was first awakened in a moment of anger, Golightly accidentally received the works of Agatha Christie as his template for how the world should work: hence the style of the murders.

Enraged at being discovered, Golightly assumes his wasp form. Agatha snatches the Firestone, screaming that her mind--that which had taught the Vespiform to kill--will find a way to destroy him. Golightly pursues her, as her thought patterns are linked to him through the Firestone. She takes a car and drives away, hysterically repeating "It's all my fault." The Doctor and Donna follow her in another car, belonging to the deceased Professor Peach, with the Doctor ominously warning that "time is in flux" - that there is no guarantee that Agatha will survive, which could leave history severely damaged.

Agatha leads the creature to a lake. The Doctor tries to persuade Golightly that he was not meant to kill, but he does not listen. Donna seizes the opportunity to snatch the Firestone and hurl it into the water. Golightly pursues it and drowns, like his father had, in the Indian monsoons forty years before.

Still linked to the necklace, Agatha nearly dies, but Golightly unaccountably chooses to release her as his last act. The psychic trauma causes retrograde amnesia, and the Doctor deposits her at the Harrogate Hotel ten days later, fulfilling the demands of history.

In the TARDIS, the Doctor produces one of Agatha's novels, and points to the copyright page in the front. The publication date is listed as the year five billion; Agatha Christie is quite literally the most popular writer of all time. The novel in question is Death in the Clouds a novel which features a wasp. Agatha Christie had somehow remembered bits of her adventure with the Doctor and Donna.

Story Notes

  • This episode is the 50th episode of the revived series of Doctor Who.
  • In terms of principal photography, this is the second story shot in the fourth series.
  • A different opening and conclusion to the episode were filmed. The two scenes take place in the mid-1970s and feature another actress playing the aged Christie, who begins the episode by having flashbacks and dreams relating to her adventure of some 50 years earlier. The ending of the episode featured the Doctor and Donna visiting Christie, upon which she begins to remember what happened and is shown a copy of the facsimile edition of Death in the Clouds from the year 5 billion. When it was decided to abandon the framing sequence, this second scene was remounted in the TARDIS. Both scenes were presented to the public for the first time in the 2008 DVD box set of Series 4.
  • Some of these characters resemble Cluedo characters.
    • Clemency Eddison resembles Mrs Peacock
    • Robina Redmond resembles Miss Scarlet
    • Colonel Hugh Curshiby resembles Colonel Mustard
    • Professor Gerald Peach resembles Professor Plum
    • Miss Chandrakala resembles Miss White
    • Reverend Arnold Golightly resembles Reverend Green
  • David Tennant's father makes a cameo as a footman.
The magnified face: a Graeme Harper signature
  • Graeme Harper's penchant for including a distorted image of a main character is present in this story. Though not included in every single story he's directed for BBC Wales, it's seen often enough to be considered something of a directorial "signature". Similar distortion is achieved through the use of other magnifying glasses in Army of Ghosts and Utopia, a curved window in Journey's End, and with mirrors in Turn Left. This time, it's Donna's face that gets "the Harper treatment".
  • There are quite many references to titles of the books of Agatha Christie, including The Body in the Library, Cards on the Table, Sparkling Cyanide, Dead Man's Folly, Why Didn't They Ask Evans?, N or M?, The Secret Adversary, Murder at the Vicarage, Cat Among the Pigeons, Appointment with Death, Death Comes as the End, The Moving Finger, They Do It With Mirrors, Endless Night, Nemesis, Taken at the Flood, and Crooked House.
    The Doctor's detox method probably won't work for humans
  • At the dinner where the Doctor spikes the soup with pepper, there is a vase of yellow iris as a table centrepiece. This is a reference to "Yellow Iris," a short story included in The Regatta Mystery and Other Stories. It was later expanded to novel length as Sparkling Cyanide, which in turn is also referenced in this episode.
  • Felicity Kendall, who plays Lady Eddison, was one of the stars of the classic BBC situation comedy, The Good Life. Her co star, Richard Briers appeared in DW: Paradise Towers as the Chief Caretaker, and in the Torchwood episode A Day in the Death as dying millionaire, Henry Parker.
  • Christopher Benjamin had previously appeared in DW: Inferno and The Talons of Weng-Chiang.
  • The Doctor's description of his cyanide poisoning as involving "inhibited enzymes" approximates the actual mechanism of cyanide toxicity. Cyanide inhibits the enzyme aa3 by binding to the iron that it contains, reducing the ability of the cell use oxygen to create the compound ATP, used for cellular energy transfer. Since 95% percent of ATP production in the Human body (and presumably also Time Lords) is aerobic, mortality via energy starvation quickly follows. The Doctor's method of uninhibiting the enzymes is nonsense, however. For humans, anyway.

Myths and rumours

  • Due to actress Billie Piper being seen on set it was thought that the unicorn was infact Rose Tyler
  • Brief glimpses of the giant wasp in this episode were included in the first Series 4 trailer; leading to speculation (since the view is too short to definitively identify the species) that this was a reference to the ongoing theme of disappearing bees.
  • Similarly, the brief glimpse in the trailer of the actress who plays Clemency Eddison, who resembles the actress who played Lady Cassandra in Series 1 and 2, led to speculation that Cassandra would appear in this episode.
  • At the beginning of the episode, the phonogram plays a march and the first notes are reminiscent of the Master's theme.

Discontinuity, Plot Holes, Errors

Is this teddy bear anachronistic — or is time just "in flux"?
  • Donna investigates a room in the manor house - which has been locked for forty years. However, in the room, there is a teddy bear. Teddy bears were introduced (and became popular) at the turn of the 20th century. It being actually locked for forty years probably wasn't literal, as the room would have to be opened, to bring food etc
  • The "thieves in the night" at the church seemed to be committing their crimes in broad daylight. Rev. Golightly is making a Biblical allusion: see 1 Thessalonians 5:2.
  • Agatha mentions her extensive study of poison, claiming that cyanide poisoning is invariably fatal. In reality it can be countered by several methods, including the administration of nitres, hydroxocobalamin or certain chelants. It is surprising that she sniffed the drink, as hydrogen cyanide is one of many poisons that can readily be absorbed via inhalation. Ms. Christie gained her knowledge of poisons by working in a V.A.D. dispensary during WWI, so she would have known this in 1926. (See The Agatha Christie Companion by Sanders and Lovallo.
  • How can the Vespiform use lead piping?
  • Even though it turns out that Reverend Golightly tried to poison the Doctor, why did the Butler still give him an odd look? A reference to the good old plot device of the Butler did it.
  • Agatha disappeared in December which is in the Winter and the weather is that of a summer or spring
  • The Doctor seems to have gotten over Jennys death pretty quickly. We can assume that some time has passed since her death, and in the episode it does not mention anything about the previous episode.
  • The Doctor states that Roger will become a lord , yet he is murdered in the episode. This creates a paradox.

Continuity

  • The Doctor suggested to Martha Jones in DW: Last of the Time Lords, that they take a trip to see Agatha Christie, but was unable due to Martha leaving at the time.
  • During the final scene, the Doctor produces a replica Agatha Christie paperback book printed in the far future. Although not an obvious cliffhanger on the order of the ending to many First, Second and Fifth Doctor stories, it does nevertheless establish the fact that traditionally bound books are still produced long after electronic editions would presumably have made them obsolete. In this sense, it may be seen as at least narratively linked to the next episode broadcast: Silence in the Library, which begins with the Doctor discussing how printed books continue on as a valuable resource into the far future. Although that would have been a convenient segue, it does not appear to be the motivation behind visiting the library. Donna indicates that they were planning to go to the beach when he suddenly changed plans and decided to go to the library. Some small amount of time must have passed between the two episodes.
  • This is the third time a famous author or playwright has appeared in the revived series: Charles Dickens (DW: The Unquiet Dead), William Shakespeare (DW: The Shakespeare Code) and now Agatha Christie.
  • The Doctor displays the ability to tell a time period by smell, (which may have been faked due to the vintage car in the driveway). However, he previously displayed this ability in WC: Scream of the Shalka. Such an ability is also referenced in BFA: The Eye of the Scorpion (although, in this, the Doctor admits to having seen ancient texts on the wall behind the TARDIS.
  • Donna stated that solving a mystery with Agatha Christie is like "...meeting Charles Dickens, and he’s surrounded by ghosts. At Christmas." (DW: The Unquiet Dead)
  • The Doctor and Donna are (again) mistaken for to be a couple, this has previously occurred in DW: The Fires of Pompeii, Planet of the Ood and The Doctor's Daughter.
