One day when visiting Thomson and Thompson at their office, Tintin takes note of a scrap of paper ripped from a can of crab meat among the belongings of a recently drowned sailor. Upon examining the scrap of paper, he sees the name "Karaboudjan" written on it and is then informed that this is the name of the ship where the sailor was employed.

After an unknown Japanese man is kidnapped on his doorstep, Tintin decides to investigate the Karaboudjan, but is immediately captured. While being held captive, Tintin discovers that the ship's cargo of canned crab meat is actually a cargo of opium. Tintin confronts the ship's captain, named Haddock, but discovers that he doesn't know about the smuggling operation, and is being deceived (and supplied with a lot of whiskey) by his first mate Allan. Along with Haddock, Tintin escapes and ends up in Morocco, where they continue their investigation of the smuggling operation.

''The Crab with the Golden Claws'' is the debut of BreakoutCharacter Captain Haddock, who was originally intended as a one-shot character, but ended up appearing as Tintin's ally in every single story after this one, eventually [[EnsembleDarkhorse eclipsing Tintin himself]] in popularity, even in the eyes of Hergé himself.

This is the first story that Hergé produced during the German occupation of Belgium (1940-1944) for the Brussels daily newspaper ''Le Soir'' ("The Evening"). During the occupation this leading French-language paper of Belgium had been handed over by the Germans to Belgian collaborators and thus was called ''Le Soir volé'' ("the stolen ''Soir''") by those who weren't collaborators. At first the instalments appeared in a weekly supplement for children, but the war paper-shortage meant that this kept getting smaller and smaller and by September 1941 it was discontinued entirely. From then on ''Tintin'' appeared as a small daily comic strip in the main pages of ''Le Soir''. ''The Crab with the Golden Claws'' was collected into a colour album. In the 1960s this version was reworked at the behest of the American publishers.

!!Tropes
* AlcoholInducedIdiocy: Most of what Haddock does.
* BedouinRescueService: Tintin, Snowy and Haddock are saved by one.
* BigBad: Omar Ben Salaad.
* CharacterDevelopment: When we first meet Haddock, he is a drunk and miserable wreck without a friend in the world and when he joins Tintin, his alcoholism means he causes more trouble for Tintin than he solves. At the end of the story, he is reformed and becomes the President of the Society of Sober Sailors! In later albums, he retains a fondness for the bottle, but is never as weak or unstable as he is here.
** The drawing of the figure for Haddock in this comic looks a bit amateurish in some cases as well, fitting this characterization. [[ArtEvolution This improves a lot in later comics]].
* ChekhovsGun: The can Snowy gets his nose stuck in turns out to be very important later on.
* CrossingTheDesert: Haddock and Tintin try to do so.
* CounterfeitCash: Thomson and Thompson are investigating counterfeit coins that they found on the drowned sailor at the beginning of the book, but this doesn't really amount to anything.
* TheDragon: Allan to Omar ben Salaad.
** DragonInChief
** [[spoiler: DragonTheirFeet: After Salaad is dealt with Allan tries to escape and Tintin has to chase him down by boat.]]
* FalseFriend: Allan to Haddock. Rather depressingly, Haddock calls him the only true friend he has when we first meet him.
* FramedForHeroism[=/=]ScaredOfWhatsBehindYou: At one point, a raging Haddock charges ahead against a group of armed Bedouin raiders, who promptly run away. It turns out they were actually running away from the reinforcements arriving behind him.
* GeorgeLucasAlteredVersion: At the behest of his American publishers, Hergé had to alter a scene in which [[ValuesDissonance Captain Haddock is caned by Allan's black henchman]] to him being caned by a Mediterranean, but white-skinned mook, to turn a black crewman of the Karaboudjan into a white one, and also to redraw some panels so that Captain Haddock [[{{Bowdlerized}} would never actually be seen holding a bottle to his lips]]! As Hergé commented afterwards: "Everyone knows that Americans never drink whisky [...] and that there are no blacks in America."
* TheHeavy: Allan.
* HeroicBSOD: Haddock enters one when he realizes he and Tintin are stranded in the middle of Sahara and will probably die of thirst.
* HeroOfAnotherStory: The Japanese police agent who is kidnapped.
* HollywoodMirage
* LighterAndSofter: The animated adaptations in comparison to the original comic book story. In at least the Remastered version of the 1990s animated series, Allan's crimes are changed from smuggling opium to smuggling diamonds. But, oddly, only in the second episode; the first episode is true to the comics by having Allan be involved in drug-smuggling, and despite the fact Allan appeared as part of the opium-smuggling ring in ''Cigars of the Pharaoh''.
* MadnessMantra: When he enters his HeroicBSOD, Haddock can only repeat the words "land of thirst" over and over.
* MeatOVision: After wandering around in the desert with Tintin for a while, Haddock envisions Tintin as a huge bottle of champagne and nearly strangles him to death trying to uncork him.
* TheMillstone: Haddock.
* NightmareSequence: Tintin dreams that he is inside a bottle when Haddock plans to uncork him with a NightmareFace so scary that we used it as the image on the NightmareFuel page for ''Tintin''.
* PetTheDog: After the Japanese appeared solely as villains in ''The Blue Lotus'', here we get a heroic Japanese character, albeit mostly off-camera.
* RedHerring: The CounterfeitCash subplot at the beginning of the story basically amounts to this.
* ShootTheMessenger: Non-lethal punching variation with Allan.
* ShoutOut:
** In the ''ComicBook/{{Agent 327}}'' album ''De Gesel van Rotterdam'' the ship Karaboudjan and Allan Thompson appear, directly referencing this Tintin album.
** In WesternAnimation/TheSimpsons episode ''In The Name Of The Grandfather'' Bart insults Belgium, to which Marge threatens him: ''"Bart, if you hate Belgium so much, maybe I should take your Tintin stories away."'' Bart then clutches a copy of ''The Crab With The Golden Claws'', promising he'll behave.
* ThirstyDesert: Tintin and Haddock cross a desert while being extremely thristy because of their lack of water.
* VillainWithGoodPublicity: Omar Ben Salaad.
* UnstoppableRage: Haddock gets truly pissed off when a band of Bedouin raiders firing at him shatter his bottle of whiskey. When Alan's men find Haddock and Tintin drunk and helpless (they were trapped in a wine cellar, and bullets had holed the wine vats) all it takes is another broken bottle to turn the tables.
