The Unicorn and the Wasp (TV story)

"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 has happened. Was it a nervous breakdown? A cry for help? Or perhaps a giant alien wasp..?

Plot
The Tardis arrives and the Doctor and Donna Noble arrive at a dinner party hosted by Lady Eddison and her husband, Colonel Hugh. One of the guests is none other than Agatha Christie. Looking at a newspaper, the Doctor finds that it is December 8, 1926, the day of Agatha Christie's disappearance. Just as this revelation is made, another guest, Professor Peach, is found, dead, in the library by Eddison's friend and companion Miss Chandrakala. He was murdered with a lead pipe.

At the scene, Donna comments on the similarity to Cluedo. The Doctor finds "morphic residue" on the floor while examining the scene, meaning that one of the guests isn't human. Agatha discreetly removes a fragment of paper from the grate on the fireplace.

Aided by Agatha, the Doctor interviews the guests while Donna goes looking for clues. During the interviews it becomes apparent to the viewer, via flashbacks seen while the guests recount their stories, that each is hiding something except Rev. Golightly.

Lady Eddison claims to be have been taking tea, in fact she was surreptitiously consuming liquor. Robina Redmond, a socialite, claims to have been using the toilet, whilst she was in the toilet, she 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 gay lover, Davenport, one of the servants. Colonel Hugh Curbishley claims he was in the study, reading military memoirs, while in fact he was in the study 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", with one letter before, but illegible. "N? or M?" asks the doctor, Agatha points out that it obviously spells the word "Maiden", although neither is able to divine the papers significance.

When Donna investigates a locked room in which Lady Eddison had sequestered herself for six months, while recovering from malaria, she is alarmed by a giant wasp out-side 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 but she escapes.

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

Hearing her scream, The Doctor, Agatha and Donna rush outside; Miss Chandrakala however 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 loosing the creature in a hall. When The Doctor shouts "Show Yourself" all of the doors open and every suspect, appears.

While the three mull over the evidence they've gathered thus far and Donna accidentally gives Agatha the idea for Jane Marple, the Doctor is poisoned with cyanide. Fortunately, an odd combination of ingredients (ginger beer, walnuts, salt (anchovies) and a shock (a kiss from Donna)) allow him to expel the poison from his mouth in the form of smoke. In return, 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, to 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.

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. Her son is revealed to be the Reverend Golightly.

Golightly killed Professor Peach when he learned that Peach had discovered the adoption paperwork. Hence the word "Maiden" on the paper Agatha plucked from the grate was in-fact read "Maiden Name".

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

Now enraged once more at being discovered, Golightly assumes into his wasp form. Agatha snatches the Firestone, screaming that hers, the mind that taught him to kill, will find a way to destroy him. Golightly pursues her since her thought patterns are also linked him through the Firestone. She takes a car and rushes away shrieking "It's all my fault, It's all my fault" hysterically. The Doctor and Donna follow her in another car with The Doctor ominously warning that "time is in flux", there is no guarantee that Agatha will survive, history may be severely damaged.

Agatha leads the creature to the lake, as shown in the picture above. The Doctor tries to persuade Golightly that he was not meant to kill but he does not listen and Donna hurls the necklace into the water. Golightly pursues it and drowns, like his father in the Indian monsoons.

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. More significantly the novel in question is Murder in the Clouds a novel which features a wasp. Agatha Christie... remembered.

Discontinuity, Plot Holes, Errors

 * The teddy bear is claimed to be 40 years old in 1926. Teddy bears were introduced around 1906.
 * The car by the lake abandoned by Agatha Christie does not look anything like the car she really owned. We don't know who the car belonged to at the end, she just got in and drove off. Also, the car was really found in a chalk pit.
 * Agatha Christie disappeared on the 8th of December, yet the garden is a nice summer setting and almost completely blooming.
 * The "thieves in the night" at the church seemed to be committing their crimes in broad daylight. Probably, Golightly was using a metaphorical expression.
 * Why was Roger murdered? This accomplished nothing. The vespiform wasn't able to hold it's human form due to being poisoned by pepper. It may have become angry or frightened and reacted by randomly killing one of the diners, or it may have chosen to kill Roger out of jealousy (since they were half-brothers).
 * Additionally, Davenport's on-screen reaction to the murder seems to be more puzzlement than grief, which is extremely odd considering he has just lost his lover. Donna, apparently having returned from comforting him, angrily comments in the next scene that Davenport cannot grieve properly because of prevailing social attitude. Perhaps his public composure was maintained at great effort to comply with social expectation.

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.


 * This is the third time a famous author has appeared in the revived series: Charles Dickens (DW: The Unquiet Dead), William Shakespeare (DW: The Shakespeare Code) and now Agatha Christie.


 * 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. However, unlike the other occasions, Christie detects that they are not married, noting the lack of wedding rings.


 * This is the third time that the Doctor has told a companion not to imitate an accent/dialect of certain time/place on Earth. The first was Rose doing a (poor) Scottish accent in DW: Tooth and Claw and the second was Martha imitating Elizabethan English in The Shakespeare Code.


 * In BFA: Terror Firma the Doctor claims that Agatha Christie traveled with him.
