The Crimson Horror (TV story)

 was the eleventh regular episode of the seventh series of Doctor Who produced by BBC Wales. It featured the return of Madame Vastra, Jenny Flint and Strax, who were last seen in The Snowmen. The episode marked the 100th episode of the revived series of Doctor Who, started in 2005.

Synopsis
A new project - Sweetville - has been opened, but only the perfect humans are allowed to live there. While Jenny, Vastra and Strax are trying to find out what is behind the project, Winifred Gillyflower, the project manager, is promoting the project. But who is the real manager? And who is the mysterious Mister Sweet?

Plot
Madame Vastra and her partners Jenny and Strax investigate 'The Crimson Horror' - a mysterious condition leaving victims with red skin and preserved like statues - after discovering that one victim has the image of the Doctor visible in one of his eyes.

Investigations lead them to Sweetville, an idyllic community run by Mrs. Gillyflower and her never-seen "silent partner", Mr. Sweet, apparently as a home for the chosen few to help them survive the coming apocalypse. Jenny goes undercover as a convert and infiltrates Sweetville, where she discovers the Doctor, chained up in a cell, but only partially preserved due to the process not working due to him not being human; Gillyflower tends to dispose of such "rejects", but he has been saved by her blind daughter, Ada, who has become infatuated with who she describes as "my monster."

The Doctor is able to reverse the process on himself and he and Jenny go off in search of Clara, who has also been preserved (this confuses Jenny as she last saw Clara killed by the ice woman months earlier). The preservation process on Clara is successfully reversed, and Madame Vastra says the substance used to create the "Crimson Horror" effect is the poison of the red leech, a parasite the Silurians considered a major threat 65 million years ago. The Doctor and Clara confront Mrs. Gillyflower, who explains her plan and reveals that Mr. Sweet is in fact a red leech who has attached himself to her chest; their plan is to launch a rocket into the skies over England and spread the leech's poison over much of the planet. Ada, listening in, learns of her mother's plans and confronts her while Jenny disables the rocket launch controls.

Holding a gun to her daughter's head, Gillyflower retreats into the rocket silo (disguised as a chimney) to activate a secondary launch control; she launches the rocket, but learns moments later that Vastra and Jenny have removed the poison payload. She decides to shoot the Doctor, but misses. Strax, who has climbed the chimney/silo from the outside, returns fire, causing Gillyflower to fall to the bottom of the silo.

As the old woman lay dying, Mr. Sweet abandons his host. Ada shares final words with her mother before killing the parasite with her cane.

Later, the Doctor returns Clara to her 21st century home, where she discovers that the two children she helps care for have discovered images of her and the Doctor in different points of time -- including a nuclear submarine in 1983 and a manor house in 1974. They also have found an image Clara does not recognize that is apparently of herself (but is in fact Clara Oswin Oswald). The children threaten to inform their father that their nanny is a time traveller unless she takes them in her time machine.

Cultural references from the real world

 * Thomas Thomas, who uses the language of a modern GPS, is an obvious reference to the popular real-world GPS service,.
 * Sweetville is based on the real-world model village of Saltaire, Yorkshire, founded in 1851 by wool industrialist Titus Salt. Titus also had a daughter called Ada, after whom a street in the village is named. Sweetville's name may also reflect the model village of Bournville whose name was later used for a brand of sweet, a chocolate bar.
 * "The Repulsive Case of the Red Leech" is an unrecorded Sherlock Holmes adventure, mentioned in The Adventure of the Golden Pince-Nez.
 * Upon returning from her adventure, Clara picks up a toy robot from the Transformers line, specifically a Galvatron action figure.
 * Several real world foods available in the 19th century are mentioned, including: Amontillado, Pontefract cakes, tea and seed cakes.
 * The episode contains the DWU's first surviving glimpse of a guinea, since The Highlanders is lost.
 * Real northern locations are mentioned, including Bradford and Buckden Pike.

Story notes

 * This story marks the first time in the revived series that a companion's associates have successfully deduced the person's time-travelling affairs with the Doctor's on their own, along with the Doctor's ability to time-travel, without questioning the Doctor directly or getting a firsthand experience of the TARDIS. Artie and Angie Maitland discovered pictures of Clara's travels from TV: Cold War, TV: Hide, and a picture of Clara during her Victorian life (TV: The Snowmen) on the Internet, which exposed her secret.
 * Likewise to the above, Clara sees herself in a past life for the first time by looking at the Victorian era photo of herself in London (TV: The Snowmen), cluing her in that she really has lived more than one life, which the Doctor confronted her over in their last adventure, TV: Journey to the Centre of the TARDIS.
 * This story marked the 100th Doctor Who episode since the programme's revival in 2005.
 * Diana Rigg is credited as "Dame Diana Rigg", the first time such an honorific has been included in a Doctor Who screen credit (by contrast, Sir Michael Gambon was not identified as such in TV: A Christmas Carol).

Production errors

 * Vastra's veil is far more transparent than it was apparently meant to be, and it can be pretty silly to see the appearance of her unveiled face be played as a complete surprise. Though one could argue that her having a type of skin condition has spread and it does at least cover the scale bit, not the green skin.


 * We hear the crowd at the meeting singing the poem (sometimes referred to as a hymn) "Jerusalem" (also known as "And did those feet in ancient time"). Although William Blake wrote the poem around 1804 Hubert Parry's melody was not composed until 1916, 23 years after the story was set.

Continuity

 * The Doctor mentioned failing to get Tegan Jovanka back to Heathrow Airport. (TV: The Visitation, AUDIO: Smoke and Mirrors, et al.)
 * The Doctor uses his fifth incarnation's often-used phrase "Brave Heart..." to Clara.
 * The Doctor does a Northern accent again. He briefly put on a Northern accent in TV: The Rebel Flesh.
 * Pictures on Angie's laptop are from TV: Cold War, Hide, and The Snowmen.
 * The Doctor is once again aided by Madame Vastra, Jenny Flint and Strax. (TV: A Good Man Goes to War, The Snowmen)
 * Strax chants the Sontaran battle cry, "Sontar-ha!" when he attacks the brainwashed humans surrounding the Doctor and Jenny. (TV: Sontaran Stratagem /The Poison Sky)
