The Red Sea Sharks (1958) is the 19th adventure of Franchise/{{Tintin}}. It is notable for its re-introduction of Tintin's RoguesGallery and a number of supporting characters. The album begins with a reference to the [[Recap/TintinLandOfBlackGold Land of Black Gold]]. In Khemed, Sheikh Bab El Ehr has finally managed to depose his rival Emir Ben Kalish Ezab. Abdullah, the RoyalBrat son of the Emir, is sent to Marlinspike Hall for protection.

In various subplots:
* Doctor J. W. Müller ( [[Recap/TintinTheBlackIsland The Black Island]], [[Recap/TintinLandOfBlackGold Land of Black Gold]]) has allied himself to the new regime in Khemed, playing an influential role under the alias Mull Pasha.
* The struggle for power in San Theodoros is still ongoing. Rival leaders General Alcazar and General Tapioca ([[Recap/TintinTheBrokenEar The Broken Ear]], [[Recap/TintinTheSevenCrystalBalls The Seven Crystal Balls]]) secretly purchase weapons from a smuggling operation.
* Leading the smugglers is J. M. Dawson, a DirtyCop previously active in UsefulNotes/{{Shanghai}} ([[Recap/TintinTheBlueLotus The Blue Lotus]]). His police days seem to be over but his criminal connections endure.
* Marquis di Gorgonzola, a CorruptCorporateExecutive, seems to have behind-the-scenes involvement in many of the recent events. His main plan however is reviving an illegal slave trade operation by abducting pilgrims to Mecca and selling them. The Marquis is actually Roberto Rastapopoulos, mastermind behind a supposedly defunct crime syndicate ([[Recap/TintinCigarsOfThePharoah Cigars of the Pharaoh]], [[Recap/TintinTheBlueLotus The Blue Lotus]]).
* Allan, Captain Haddock's former second-in-command ([[Recap/TintinTheCrabWithTheGoldenClaws The Crab with the Golden Claws]]), resurfaces as captain of a slave ship.

Tintin has to face many of these old foes in order to resolve the situation in Khemed and in the revived African slave trade.
* AbandonShip: Tintin and Haddock's kidnappers abandon ship after the engine breaks down, only for Haddock to fix it later and take over the now-repaired ship.
* [[spoiler:AmericaSavesTheDay: While Americans in previous albums are typically villains, this album culminates with the USS Los Angeles coming in to rescue the heroes from submarine attack. The United States Navy saves the day.]]
* BadlyBatteredBabysitter: Nestor, the butler of Marlinspike Hall. While Haddock is off adventuring, Nestor has to take care of young Prince Abdullah. The situation is "a little trying" on him. He loses a lot of weight while taking care of the RoyalBrat.
* CentipedesDilemma: Captain Haddock is unable to sleep after Allan mockingly asks him if he sleeps with his beard under or above the covers. This ends up saving his life and those of [[NiceJobFixingItVillain everyone on the ship.]]
* CompletelyDifferentTitle: ''Coke en stock'' ("Coke On Board") was translated into English as ''[=Tintin=] The Red Sea Sharks'', perhaps because the first word in the title might be taken to mean Coca-Cola (the story reveals it to be a code word for slaves). "Coke" can of course mean "Cocaine" and the original intended meaning of [[ a kind of coal]].
* CoolBoat: The escape submarine concealed in a "sinking" motorboat.
* [[ThreateningShark Everything's Even Worse With Sharks]]: Despite the English title, this story actually features just one shark. [[spoiler:It swallows a bomb that was meant to be planted on the side of a ship, unintentionally saving the lives of everyone on board and blowing itself up in the process.]]
* [[spoiler:FeedItABomb: A shark accidentally swallows a mine intended for Tintin's boat. We hear it hiccup for a while, then it culminates with a "hic'''BOOOOOOOOOMMMM'''".]]
* HaveAGayOldTime: Tintin, Haddock and Piotr Skut are adrift on a raft in the middle of the Red Sea. They eventually are sighted by some passengers in Gorgonzola's ship, after which a woman immediately shouts to the latter, "Look! Shipwrecks! How madly gay!"
* HeelFaceTurn: Skut falls in with the heroes pretty much instantly after they rescue him from his downed plane. It helps that he really wasn't anything more than a PunchClockVillain in the first place.
* LostAtSea
* TheNamesake: The English title for this story is a reference to a single shark which appears in one of the closing scenes. In the original French and most other languages, this album is known as "Coke on Board", with "coke" or some variant being a code-word for human cargo being shipped to slavery. Coke is a form of fuel, derived from coal. it is used here as a synonym for "black".
* RebusBubble: Haddock has one of these.
* RoguesGallery: The album brings back many of Tintin's old enemies and [[OneDegreeOfSeparation connects them to each other in various ways]]. Included are Dawson (''The Blue Lotus''), Bab El Ehr (''Land of Black Gold''), General Tapioca (mentioned in ''The Broken Ear''), Dr. Müller (''The Black Island''), Rastapopoulos (''Cigars of the Pharaoh'' and ''The Blue Lotus''), and Allan Thompson (''The Crab with the Golden Claws'' and, in a later edition, ''Cigars of the Pharaoh'').
* SubmarinePirates: Di Gorgonzola's slaver gang uses several ships and one submarine to attack targets. The submarine is a German Type VII U-boat.
* [[spoiler:SuicidalGotcha: Villainous example. Recurring BigBad Rastapopoulos has been caught as the master of the EvilPlan which involved [[MoralEventHorizon literal slave-trading]], and the navy is closing on his superyacht. He goes out in a launch, supposedly to give himself up, but it suddenly sinks. The heroes and the world media think that he is dead, but he has in fact escaped in [[EscapePod a mini-submarine hidden in the launch]].]]
* WantedPoster: Wanted posters for Tintin and Haddock in Khemed.
* WhosOnFirst: Haddock asks a shot-down fighter pilot his name and he thinks he's replying "scoot!" as a rejection. Turns out he's Estonian and his name is actually Piotr Skut.
* WideEyedIdealist: Subverted with the black Muslims whom Allan and Rastapopulous are slave-trading under the guise of transporting them to Mecca on the Hajj. Initially Haddock is completely unable to convince them of this, but after a bit of consideration, most of them decide he probably has a point, as some previous hajjis Allan took on the journey never came home.
