Agatha Christie

Dame Agatha Mary Clarissa Christie was a famous English human writer best known for her murder mysteries. Her prolific body of work was in print billions of years after her death, establishing her as the best-selling author of all time. She was also known for having disappeared in 1926, being found in a hotel under an assumed name and claiming no memory of the ten days that she had been missing.

Meeting the Doctor
In 1926, Agatha learned her husband - World War I hero Archie Miller - had begun an extramarital affair. She nevertheless attended Lady Eddison's party as guest of honour, carrying on with her life. There, she met the Tenth Doctor and Donna Noble, whom she quickly grew to trust when another guest, Professor Peach, was found murdered in the library. Agatha found a piece of paper in the library fireplace while the Doctor investigated the Professor's body for clues; he had died at 4:15 PM.

After the Doctor established himself as Chief Inspector Smith from Scotland Yard, she assisted him by having the five suspects wait in the sitting room until he finished investigating an unnoticed morphic residue, and also took issue with his enthusiasm at getting to solve a case with her, saying she would work with him "for the sake of justice, not for your amusement." . Afterwards, she joined him in questioning the suspects while Donna investigated upstairs. This got them nowhere until the Doctor noted he had seen her taking the little piece of paper; it said "Maiden". They were left with no clues unless Donna managed to find anything of interest in the rooms above.

Along with the Doctor, Agatha later went to Donna, who was screaming in terror at a giant wasp; Agatha misinterpreted the "giant wasp" to be a simple bee. However, the stinger the wasp had left embedded in the door changed her mind. The Doctor explained, in big words, that there are plenty of alien insects, but none live in Earth's galactic vector. Thinking the Doctor had lost his mind, Agatha told him there was no thing as giant wasps; he agreed, but pointed out the question was why it was there.

She later went outside with them to find Ms. Chandrakala had been crushed by a gargoyle and had said "the poor little child" before passing; the giant wasp had pushed the statue on her from above. Spotting the wasp, Agatha now believed something was afoot, but still didn't think the wasp was real until she came face to face with it. It fled into a corridor and resumed human form amongst the other guests. Afterwards, Agatha was visibly suffering from a crisis of confidence in her work, but Donna did her best to sit down with her and cheer her up, armed with the knowledge not only of Christie's greatness but also the fact that she'd found the Doctor again after the disaster with Lance on her wedding day. (TV: The Runaway Bride)

''Agatha, people love your books. They really do. They're going to be reading them for years to come. -Donna Noble (TV: The Unicorn and the Wasp'') ''If only. Try as I might, it's hardly great literature. Now, that's beyond me. I'm afraid my books will be forgotten, like...ephemera. -Agatha Christie (TV: The Unicorn and the Wasp'')

After the wasp - in fact, a Vespiform - had claimed Lady Eddison's son and heir Roger as its latest victim at dinner, Agatha pointed out, when she saw that the Doctor was still grappling with what could drive a Vespiform to kill, that "The murderer is as human as you or I." The Doctor had an epiphany, saying he'd forgotten she was the expert, and disregarded her dismissing herself as a "purveyor of nonsense" and encouraged her to crack the case.

"Oh, no, no, no, no. 'Cause plenty of people write detective stories, but yours are the best. Why? Why are you so good, Agatha Christie? Because you understand. You've lived. You've fought, you've had your heart broken...you know about people. Their passions, their hope and despair and anger - all of those tiny, huge things that can turn the most ordinary person into a killer. Just think, Agatha! If anyone can solve this, it's you. -The Tenth Doctor (TV: The Unicorn and the Wasp)"

With everyone gathered, Agatha (with the Doctor's assistance in extraterrestrial matters) revealed the Unicorn was pretending to be Robina Redmond, one of the guests, and that Lady Eddison had had a child before Roger with a a Vespiform in India forty years earlier. That child was the very Reverend in that room, Arnold Golightly; his mind was overloaded with the contents of The Murder of Roger Ackroyd when the Firestone linked his mind to Lady Eddison, who was reading that book.

Enraged by being discovered, the Reverend chased after Agatha, who had taken the Firestone to lead him away lest he murder again. She led him to the lake, where she planned to drown herself and it. Luckily, Donna and the Doctor arrived, tossing the jewel into the lake, causing Golightly to go after it and drown. However, Agatha's mind was linked to him and she began to die with him until he decided to let her go for unknown reasons.

The stress from the link made her lose her memories; the Doctor took her forward eleven days and left her outside a hotel in Harrogate, where she revived with no conscious memory of the events. As the Doctor told Donna, she would go on to lead a great life, not only continuing to write but also seeing the world and remarrying (she wed archeologist Max Mallowan in 1930 - a marriage that lasted until her death.)

Fragments of memory later emerged in her storytelling, including Donna's suggestions of her later books, as well as the Vespiform's wasp-like appearance, which inspired the cover of a book, Death in the Clouds. (TV: The Unicorn and the Wasp)

Works
Apart from The Murder of Roger Ackroyd, Christie had written five other novels by 1926, but had not yet written Murder on the Orient Express or Murder at the Vicarage, which the Doctor had mistakenly referred to as Murder at the Vicar's Rage after Golightly's death. A subconscious memory of the Vespiform remained with Christie; a wasp played a role in one of her later novels, Death in the Clouds (TV: The Unicorn and the Wasp). Centuries after its publication, a copy of Murder on the Orient Express found its way into the possession of Professor Lasky. (TV: Terror of the Vervoids)

Christie's works were still in print as late as the year 5,000,000,000, including Death in the Clouds.

Many of Christie's works - along with her two best-known detectives, Hercule Poirot and Miss Marple - were mentioned during the Tenth Doctor's time with her. Christie herself imitated Poirot's accent when she said, "Use...ze little grey cells." (TV: The Unicorn and the Wasp)

The Doctor also foretold her knighthood when he called her "Dame Agatha" (TV: The Unicorn and the Wasp) even though she was not knighted until the 1971 New Year Honours List named her Dame Commander of the Order of the British Empire.

Inspiration
The Doctor's adventures offered subconscious inspiration for Agatha Christie. Donna Noble accidentally inspired her novel Murder on the Orient Express and the character Miss Marple. The Vespiform and the Doctor would also inspire Death Comes As The End, Murder at the Vicarage and Death In The Clouds. (TV: The Unicorn and the Wasp)

Other information

 * The Eighth Doctor had a signed first edition printing of The Murder of Roger Ackroyd which was missing the last page, leaving him to believe he would never find out who did it. (AUDIO: Storm Warning)
 * He also once claimed Christie had travelled with him. (AUDIO: Terror Firma)
 * Despite this, the Tenth Doctor later declared to Martha Jones he wanted to meet her. (TV: Last of the Time Lords)
 * Trying to remember the name of the St Agnes Abbey, Clyde Langer could only remember that he thought it was some lady writer's name or her old lady detective. He didn't remember the name until Sarah Jane Smith guessed Agatha Christie. (TV: Eye of the Gorgon)

Influence
The murder mysteries of Agatha Christie had possibly already inspired the Doctor Who television story The Robots of Death, the Big Finish Productions audio play The Chimes of Midnight and, arguably, another television story, Horror of Fang Rock.

Actor's View/Preparation
In her Q&A for Doctor Who Magazine, Fenella Woolgar said she read The Murder of Roger Ackroyd and Christie's autobiography to prepare for the role. When she won the part, she was also reportedly the first casting suggestion from David Tennant to be approved.

Woolgar also said she approved of the idea of Christie being a companion of the Doctor, and when Doctor Who Magazine remarked, "Who knew Agatha Christie could be sexy, eh?", she informed/reminded them that Christie had had quite a few admirers for her looks when she was younger. This would make sense - Christie was 36 at the time of her disappearance, which meant she would be the same age meeting the Doctor and Donna, and lived to be 85.

Historical accuracy
Though Christie disappeared on December 8th, The Unicorn and the Wasp does not appear to be set in early December. Furthermore, the episode shows her car being left by the side of the lake where Golightly perished whereas in real life, her car was found at Newlands Corner in a bush overlooking a chalk pit. However, Doctor Who Confidential's matching episode, Nemesis, showed that a Morris Cowley, which Christie was actually driving at the time, was used during filming.

Also, she did not turn up at the Harrogate Hotel, but at the Swan Hydropathic Hotel (which is now the Old Swan Hotel), which is also in Harrogate (for those interested, she had checked in as a "Mrs Teresa Neele" from Cape Town - and had possibly gotten the idea for the name from the fact that her husband's lover was named Nancy Neele.) However, she was diagnosed by two doctors with psychogenetic fugue, of which selective amnesia is a symptom.

When the Doctor recognizes that he's been poisoned, Agatha recognizes that his drink contains cyanide and professes that she's an expert in poisons and that she knows that cyanide is incurable and fatal (at least to humans.) This is partially true - she was an expert in poisons (knowledge that she utilized in her post-WWII works) but gained the knowledge while working in the pharmacy of University College Hospital in London during World War II, which would be at least 13 years after she supposedly met the Doctor and Donna.

The key thing was that the disappearance gave the creative minds behind the show the idea for the episode. Perhaps the ultimate Christie seal of approval was when her grandson Mathew Pritchard was present at the script read-through and readily gave The Unicorn and the Wasp his blessing on behalf of the Christie estate.

Deleted Scene
In a scene included in the Series 4 DVD, late in her life, soon before her death, Christie begins to experience dreams and flashbacks of her adventure with the Doctor. Ultimately, the Doctor and Donna visit her, at which point her memories of the adventure began to return; the Doctor reminds her of what happened. This scene does not present a continuity issue, as Donna is seen to be basically parroting the words the Doctor said to her regarding Agatha being the best-selling writer of all time in the original ending, allowing both to exist. The fact the Doctor has chosen to inform Agatha about the future edition of her books as well as reminding her about what happened suggest the meeting takes place soon before her death, which would place the scene in 1976.
