->''"Doctor, you make me wear strange clothes, you tell me nothing: you are trying to annoy me." ''
-->-- '''Leela'''

The racist one.

Doctor Who goes all ''Literature/SherlockHolmes''[[JustForFun/XMeetsY -Meets-]] Film/HammerHorror in this tale set in VictorianLondon. Police pathologist Professor George Litefoot is investigating a body found floating in the Thames, and, with help from the Doctor, determines that hairs found on the body come from a giant rat. Also, Leela has to wear period clothing and learn table manners.

Moving into the sewers to investigate, the Doctor, Leela and Litefoot discover giant rats on the loose and follow the trail to the Palace Theatre. Stage magician Li H'sen Chang has been kidnapping young "[[GettingCrapPastTheRadar wretched girls]]" for his master, the ancient Chinese god Weng-Chiang. In reality, "Weng-Chiang" is the 51st century war criminal Mangus Greel (Upon hearing about the Doctor's presence in Victorian England, Greel worries about the presence of "Time Agents" - he clearly comes from the same 51st century as a certain conman we meet [[Recap/DoctorWhoS27E9TheEmptyChild many years later in the Revival Series]]). Greel feeds on the kidnapped girls' lifeforce to stabilise his molecular structure, which was ravaged by the trip through time. The theatre's owner, Mr. Jago, teams up with the Doctor to try and stop his former employee.

Greel's "Time Cabinet" was lost in London and has been found by Litefoot, so Greel sends Chang's ventriloquist's doll, "Mr. Sin" (a computerised homonculus with a pig's brain... well, [[Recap/DoctorWhoS27E9TheEmptyChild the 51st century]] is a bit weird like that) to infiltrate Litefoot's house and retrieve it. Mr. Sin succeeds, but the Doctor and friends manage to intervene before Greel can escape. He falls into his own lifeforce-extracting machine and is disintegrated, before the Doctor manages to deactivate Mr. Sin. The Doctor buys everyone muffins to celebrate.

Another episode by Creator/RobertHolmes, this episode is markedly DarkerAndEdgier, HotterAndSexier, as well as BloodierAndGorier than most of classic ''Series/DoctorWho''.

The characters of Jago and Litefoot became quite popular with fans, and for years rumours abounded about a planned spin-off centred around the duo solving crimes in Victorian London, and it was even seriously considered by the BBC a couple of times. While the spin-off never made it to TV, Jago and Litefoot, along with PC Quick, eventually ended up getting their own AudioPlay/BigFinishDoctorWho spinoff range. It also occasionally features the Fourth and Sixth Doctors, as well as Leela.

Creator/ChristopherEccleston watched this serial to [[http://www.whoviannet.co.uk/info/didyouknow.php prepare for his role as the Ninth Doctor]].

----
!!Tropes
* AddedAlliterativeAppeal: As many of Jago's lines as he can possibly manage.
* AbsurdlySpaciousSewer: Magnus Greel's lair is in the sewer, the entrance to which is guarded by a giant rat.
* {{Adorkable}}: Jago isn't nearly as brave as he pretends and Litefoot acts very awkwardly around Leela.
* AffablyEvil: Li H'sen Chang. He makes a HeelFaceTurn eventually.
* AIIsACrapshoot: Mister Sin.
* AlmostDeadGuy: Li H'sen Chang.
* AsianSpeekeeEngrish: Used by Chang in his act, seeing as how if he spoke normally, his Victorian audience would doubt that he is actually from China.
* AttackOfTheKillerWhatever: There's a killer ventriloquist's dummy.
* BadassBoast / FacingTheBulletsOneLiner: Leela's response to an imminent and agonizing death at the hands of Magnus Greel shows a marked difference in attitude to that of previous female companions.
--> "[[SeeYouInHell When we are both in the Great Hereafter]], I will hunt you down, Bent-Face! And put you through my agonies a thousand times!"
* BadGuysDoTheDirtyWork: Sin kills off the Tong of the Black Scorpion when he goes out of control.
* BatmanGrabsAGun: He even actively asks for it. Not that he would use it on a human, but the Doctor does shoot a giant rat with it.
* {{BFG}}: Lightfoot's elephant gun is the period equivalent.
* BigBad: Weng-Chiang aka Magnus Greel.
* BlackComedy: On being introduced to Li H'sen Chang the Doctor asks to see a trick. The Tong member promptly drops dead from the suicide pill. The Doctor applauds.
* BodyHorror: We get a very brief look at Greel's face. We see that ''half of his face is melting!!!''
* BoundAndGagged: Leela in Episode 6 as she is put in Greel's machine.
* BreakoutCharacter: Jago and Litefoot, who got their own ''extremely'' successful audio spinoff.
* TheButcher (of Brisbane): Magnus Greel.
* CallForward: While it's likely only a coincidence, Jago's distraction in order to distract Mr. Sin is remarkably similar to a "strategy" the Eleventh Doctor attempts, [[Recap/DoctorWhoS31E12ThePandoricaOpens over 900 years later]]. Perhaps Mr. Jago was The Doctor's inspiration.
* CallBack: A rather sneaky one: The Doctor mentions he hasn't been to China for [[Recap/DoctorWhoS1E4MarcoPolo about 400 years.]]
** Though that would actually be about 600 years ago. Of course, the Doctor could be referring to another adventure.
* ChangedMyJumper: When the TARDIS first materializes, Leela steps out complaining about having to wear appropriate clothes. The Doctor's voice from inside the TARDIS tells her, "You can't go around VictorianLondon in skins, you'd frighten the horses." Then [[HypocriticalHumor he himself emerges in the stereotypical Sherlock Holmes outfit -- only more colorful --]] and says, "We don't want to be conspicuous, do we?"
* ChineseLaunderer
* ClarkesThirdLaw: Chang's magic is accomplished using 51st century technology.
* ConcealmentEqualsCover: A flimsy wooden table is enough to shield the protagonists from FrickingLaserBeams. The laser beams at least start punching holes through the table, though.
* TheConsigliere: Li H'sen Chang in is this to Magnus Greel, reminding him some things are not workable.
* ContrivedCoincidence: The Time-cabinet that Greel is after could be anywhere in London, but as a matter of fact it's in the home of the same pathologist the Doctor has already befriended.
* CreatorCameo: Composer Dudley Simpson has a cameo as the conductor of Jago's theatre orchestra.
* CyanidePill: Li H'sen Chang slips a scorpion venom pill to a member of the Black Scorpion Tong who has been captured by the police, who then commits suicide to avoid revealing anything under interrogation. Later on, Weng-Chiang forces another Tong member to commit suicide after he makes a mistake, laughing maniacally as the man dies in agony.
* DarkerAndEdgier: Heavily implied underage prostitutes. Leela in completely soaked clothes. A guy getting his leg ripped off and dragged through the water, and subsequently smoking opium ''on screen'' to dull the pain before he dies in the Doctor's arms. Producer Philip Hinchcliffe had been axed for excessive horrific content and in this, his final serial, had nothing to lose.
* DemonicDummy: Mister Sin is presumed to be one at the beginning of the serial.
* DisappearingBox: Li H'sen Chang uses this in his act.
* DisposableSexWorker[=/=]DisposableVagrant: Greel identifies his victims as "a few contemptible slatterns who will never be missed"; Chang protests that they ''are'' being missed and it's getting people's attention.
* EarthThatUsedToBeBetter: We learn that in the 51st century, World War VI triggers another wave of colonisation.
* EurekaMoment: The story makes fun of the word itself: the Doctor claims that it translates from Greek as "This bath is too hot."
* EvilLaugh: Greel gets an amazing one in the episode 4 cliffhanger.
* {{Expy}}: The original draft of the serial actually had the Master as the villain, but he was vetoed. Magnus Greel is also a black-cloaked, physically-decayed villain with a time machine trying to stave off his own death, as the Master was in [[Recap/DoctorWhoS14E3TheDeadlyAssassin "The Deadly Assassin".]] As "Minister of Justice" for the Supreme Alliance and a mad scientist who experiments on humans Greel also combines traits of Heinrich Himmler and Josef Mengele.
** Li H'sen Chang was clearly based on ''Literature/FuManchu''.
* FacialHorror: When we briefly glimpse Greel's face, we can see that the right half is ''melting'' due to a mutation that occurred during time travel.
* FishOutOfTemporalWater: Leela doesn't adapt well to Victorian values.
* ForTheEvulz: Sin seems to end up like this, killing for the sake of it. He even shoots the Mooks.
* ForScience: When the Doctor says a 100,000 deaths can be laid at Greel's door, Greel says they were used for science.
* GenreRefugee: The story is about putting the Doctor and Leela into the roles of Sherlock Holmes and Dr. Watson and pitting them against characters lifted from Fu Manchu stories.
* GettingCrapPastTheRadar:
** The "wretched girls" who are taken from the streets wear layers of makeup and red clothing, and it's remarked that they can't be older than 16.
** Leela has a SexySoakedShirt moment just after the giant rat sequence that apparently has not been edited out in over 30 years.
* GlowingEyesOfDoom: Li H'sen Chang's eyes glow whenever he hypnotises someone.
* GodGuise: Magnus Greel posing as Weng-Chiang, though he doesn't try to hide his identify from Chang to whom it makes no difference anyway, as [[FromNobodyToNightmare Greel has raised him up from his humble life as a peasant to a man who performs before royalty]].
-->'''Doctor:''' "You know he's not a God, don't you?"
-->'''Chang:''' "He came to me like a God, in his cabinet of fire!"
* GoodScarsEvilScars: Greel's face is terribly disfigured due to his faulty time machine. He wears a mask to cover this, until [[TheReveal Leela rips it off in part 5 and exposes his horrible face.]]
* GrandFinale: For producer Phillip Hinchcliffe. This was his last serial because he was fired due to complaints that the program was too scary for children, so he pulled out all the stops for this story with a higher budget than normal.
* HeelRealisation / DeathEqualsRedemption: Chang.
* HeroWorshipper: Jago, towards the Doctor. He constantly praises the Doctor's cleverness and resourcefulness.
* HisNameIs: Chang survives the giant rat enough to tell the Doctor that Weng-Chiang is in the "House of the Dragon", but not long enough to actually tell where it is.
* HistoricalVillainUpgrade: Greel thinks this has happened to him in the future when the Doctor refers to his crimes, saying the winning side writes the history. Considering he is a sadistic murderer who admits to killing 100,000 people for his experiments this seems unlikely.
* HoistByHisOwnPetard: Greel ends up killed by his own life-extraction chamber.
* HostageForMacguffin: The Doctor refuses to give the Time Key before Jago and Litefoot are freed. Later, he adds that he wants the girls that are to be Magnus's next meal freed, too. Too bad it doesn't work.
* HumanSacrifice: Jago thinks the Chinese will do this. Litefoot says he's thinking of the Druids.
* HypnoticEyes: Li H'sen Chang can hypnotise girls with just a look.
* IdenticalLookingAsians: Chang sarcastically says, "I understand we all look alike," when the Doctor asks if they've met before.
* INeedAFreakingDrink: Well, more of ''You'' Need A Freaking Drink, as Jago offers Casey a drink to help him calm down. Then Casey proceeds to drain the flask.
* InstantSedation: Possible subversion -- the title villain uses an unspecified knockout drug on a cloth to capture Leela, and she goes down fast... but she has enough time to [[NightmareFace tear the villain's mask off]].
** Given the time period, it was probably either chloroform or ether.
* InThePastEveryoneWillBeFamous: Not in the events of the story, but the Doctor mentions having shared a meal with the Venerable Bede.
* JackTheRipoff: The disappearances and murder of several women in Whitechapel? You guessed it. The original draft had the Doctor chasing Jack the Ripper.
** Casey, the theater stagehand, hangs a lampshade on this. Jago is immediately dismissive.
* LargeHam: MAGNUS GREEL!!!!! Dear Lord, he was always ranting and raving about something.
-->'''Magnus Greel:''' Let the [[TitleDrop talons of Weng-Chiang]] tear your flesh-ah!
** Henry Gordon Jago comes a fairly close second.
* LifeDrain: Greel has Chang kidnap young women so Greel can drain their life essence to improve his own failing health after the time machine malfunction.
* LifeDrinker: Magnus Greel attempts to stay alive by draining the life essence out of young women. Leela only just avoids suffering this fate.
* LovableCoward: Jago. He even admits to it.
* MagiciansAreWizards: Li H'sen Chang is a StageMagician... and a bit more, with the technology given to him by his master.
* MindControl
* MoodWhiplash: Moments after all the villains have been killed, the Doctor cheerfully offers to buy everyone muffins.
* {{Mooks}}: The Tong of the Black Scorpion.
* NiceHat: The Doctor, Leela, Chang's thugs, and Greel each have one; Chang has two.
* NightmareFace: Magnus Greel has a melted, spaghetti-like face due to a mutation.
* OpiumDen: Though Li H'sen actually only uses opium to numb the pain from his rat-chewed leg.
* PaperKeyRetrievalTrick: Used by the Doctor to break into the laundry house. Use of this trope caused controversy, as the British Board of Film Classification argued that it would teach children criminal skills; the show's producers successfully argued back that Enid Blyton used the same trick in her children's books, and it didn't work on modern locks anyway.
* PigMan: The Peking Homunculus is a murderous midget robot made from the cerebral cortex of a pig.
* QuintessentialBritishGentleman: Litefoot. Jago merely ''thinks'' he is.
* RaisedByNatives: The Doctor's cover story for Leela.
* ReliablyUnreliableGuns: Litefoot worries that the Doctor's elephant gun (which hasn't been used in years) might go off in the Doctor's face. "Nonsense," the Doctor assures him, "it was made in Birmingham."
* RodentsOfUnusualSize: The rat.
* SeeYouInHell: Leela gets a CrowningMomentOfAwesome when she tells the villain she'll ''hunt him down in the next life''.
* ShoutOut:
** To ''Literature/TheImportanceOfBeingEarnest'' ("A hatbox?").
** Jago's alliterative speeches are a shout out to Leonard Sachs's turn as the compere in the BBC's music-hall revival show ''The Good Old Days''.
** And, of course, the idea of a [[ThePhantomOfTheOpera disfigured maniac hiding under a theatre]].
** Li H'Sen Chang is a villainous fictional version of the real-world ([[{{Yellowface}} fake]]) Chinese conjurer Chung Ling Soo.
** Litefoot's landlady is named [[Literature/SherlockHolmes Mrs. Hudson]].
** The Doctor [[Literature/TheWindInTheWillows enjoys messing around in boats]].
** The giant rat is also reminiscent of animals grown to enormous size in ''Literature/FoodOfTheGods''.
** UsefulNotes/JackTheRipper is mentioned.
** Litefoot quotes from ''Literature/ThePilgrimsProgress'' and attributes it to Creator/JohnBunyan.
** The Doctor quotes from the monologue ''Literature/TheGreenEyeOfTheYellowGod'', incorrectly attributing it to Creator/HenryChampion.
* ShutUpHannibal: When Greel talks about how he is remembered as a villain due to the other side writing the history and how the people he killed helped his time travel experiments the Doctor tells him the people were slaughtered and that the experiments came to nothing.
* SkewedPriorities: Mr. Jago's first concern when he discovers his employee has been helping to murder many innocent young women is how he can make a profit with a guided tour of the villains lair.
* {{Slurpasaur}}: That giant rat is played, at least in part, by a perfectly normal rat in a model sewer.
* SmallNameBigEgo: Jago acts like a brave, clever detective hero but he can't walk the talk.
* SmartPeoplePlayChess: The Doctor puts Greel into Checkmate. Greel [[SoreLoser knocks the pieces over]].
* {{Spinoff}}: Jago & Litefoot were so popular that a spinoff was briefly discussed; 30 years later, Creator/BigFinish gave them [[http://bigfinish.com/311-Doctor-Who-The-Companion-Chronicles-The-Mahogany-Murderers their own story]] and, in 2010, [[http://bigfinish.com/Jago-and-Litefoot their own series.]]
* SpotOfTea: Litefoot attempts to example the etiquette of tea to Leela, who gets very confused.
* StraightMan: Litefoot acts as this when confronted by Jago's ego, Leela's lack of social etiquette and the Doctor's general weirdness.
* SurroundedByIdiots: "Your opium-addicted scum are all bunglers, Chang!"
* SuspiciouslySimilarSubstitute: Magnus Greel is one for the Master, as the story originally followed up on his escape in "The Deadly Assassin". Remnants of that idea include both being hammy, vampiric serial killers on the run with a time machine, dying and desperately looking for a way to cheat death. Magnus even talks about ''regeneration'' a few times.
* TheatrePhantom: Magnus Greel is a disfigured genius dwelling the cellars of a theatre; his mangled face concealed by a mask. He also uses holographic ghosts to keep the stagehands away from the hidden opening leading to his hideout, which leads to rumors that the theater is haunted.
* TitleDrop: When Magnus is about to kill Leela, he drops the serial name. (Actually, the serial was renamed using this line shortly before production began.)
* ThoseTwoGuys: Jago & Litefoot, the most iconic example of the Creator/RobertHolmes double act. Jago owns the theatre where Weng-Chiang is hidden and his agent plies his trade, and Litefoot is a police pathologist and the Doctor's de facto landlord for the story. Both important to the plot to the point that they are more important than the Doctor until the finale. In fact; Jago and Litefoot were so popular they eventually got their own series.
* TranslationConvention: The Doctor and Litefoot both get to show off their fluency in Chinese, but all conversation between Weng-Chiang and his Chinese henchmen is in (bad) English.
* TheTriadsAndTheTongs: Greel's mooks are members of the Tong of the Black Scorpion.
* TwoFaced: The right half of Greel's face is melted and looks like soggy noodles.
* VictorianLondon
* TheWatson: Interestingly enough, NOT Leela. As [[http://www.avclub.com/tvclub/doctor-who-classic-the-talons-of-weng-chiang-63742 the AV Club]] noted, Jago and Litefoot fulfill the role of Watson - Jago behaves as the traditional film depiction of Watson being a pompous, boisterous, easily puzzled sleaze while Litefoot behaves as literature's Watson being a quiet, calm, observant gentleman.
* WhatHappenedToTheMouse: Dying and unable to speak, Chang tries to give the Doctor a clue to Greel's headquarters by pointing to his shoe. The Doctor makes a few guesses about the clue but then finds the location another way. The meaning of the shoe-clue is never explained.
* WholePlotReference: To the Creator/HammerHorror film ''The Terror Of The Tongs'', but incorporating elements of Sherlock Holmes.
* WorldWarWhatever: Greel is described as having almost caused World War Six.
* TheXOfY: One of the over 100 ''Doctor Who'' episode titles to be this.
* {{Yellowface}}: A particularly noteworthy example, especially within the annals of Who.
* YellowPeril: Which along with the Yellowface led to the story being [[BannedInChina Banned In Canada]].
* YouHaveFailedMe: Averted. TheDragon is simply fired, and sets out to save face on his own.
** Later on, a Tong member who failed one time too many is forced to commit suicide.
* YouRebelScum: Magnus Greel repeatedly refers to his Tong hatchetmen mooks as "opium-addicted scum".
