Captain Haddock the Picaros", when Professor Calculus 'cures' him of his taste for alcohol. In the adventure "Secret of the Unicorn" (and continuing in "Red Rackham's Treasure") he and Tintin travel to find a pirate's treasure captured by his ancestor, Sir Francis Haddock (François de Hadoque in French). With newfound wealth and regaining his ancestral home Marlinspike Hall, Captain Haddock becomes a socialite; riding a horse, wearing a monocle, and sitting in a theatre box seat ("The Seven Crystal Balls"). He then evolves to become genuinely heroic, volunteering to sacrifice his life to save Tintin's own in the pivotal "Tintin in Tibet".
Tintin (character) uncomplicated as the story line". Hergé never explained why he chose Tintin as the character's name. He had previously made use of alliteration with the name of his previous character, Totor. Michael Farr speculated that Hergé had adopted it from Rabier's "Tintin le lutin", although Hergé insisted that he did not learn of this book until 1970. Farr commented that "Tintin" was probably the character's surname, as other characters, such as his landlady, occasionally refer to him as Mr. Tintin (as printed on his doorbell). Conversely, Assouline asserted that it could not be his surname, because he lacked a family.
