rescued by Snowy dropping a rope into it. Back in town, they find themselves pursued by the police, who chase them all around a market. Tintin and Haddock escape thanks to Bianca Castafiore. After an unexpected visit by a delegation from the visiting Emir of Sakali, Tintin and Haddock meet up again with their young friends. They decide to sneak back into Professor Zalamea's hacienda to test some new information, that is, the role of Estensoro (Zalamea's manservant) in the kidnapping. After successfully using animals with pans tied to their tails as a distraction, Tintin and Haddock find a radio identical to Fernando's in Estensoro's room, proving his involvement. Haddock's decision to drink Estensoro's whisky accidentally leads them to discover Zalamea's secret documents, and his own suspicions about the identity of his enemies. Back at the villains' hideout, the professors manage to make a broadcast describing their whereabouts. Estensoro hears the broadcast and races off to inform his boss. Luckily, Tintin and Haddock also hear the broadcast and set off in hot pursuit. After a brief struggle, Estensoro is overcome, but the professors are nowhere to be found. The new kidnappers evidently had no use for the Thom(p)son twins, as they are discovered still tied up (much to the Captain's enjoyment). Snowy discovers an agal belonging to one of the Arab kidnappers, and Tintin realises that the rich Emir of Sakali (who had courted Bianca Castafiore earlier in the film) was the same man as the Arab enemy described by Professor Zalamea. The rich Emir of Sakali's yacht is moored up at the docks, so Tintin and the Captain try to rescue the professors, but they have been drugged, and their loud voices raise the alarm, and Tintin and Haddock are caught by the emir. They escape and a fight ensues, as a horde of children turn up (warned by Snowy). The villains are thrown in the sea, the emir is subdued, and the police arrive to clean things up. All turns out well and they are back at Marlinspike Hall for a celebration and photos. It is said that they hope to perfect the oranges within 10 years and also to learn to grow wheat, potatoes, eggplants, etc. in the desert. Just then, Thomson and Thompson turn up in their car, crash, and end up in the fountain, to the amusement of all. Greedy dogs eat a "THE END"
