Captain Haddock home, Marlinspike Hall (or "Moulinsart" in the original French). Harry Thompson, author of "Tintin: Hergé and his creation", writes that the introduction of this large and luxurious country house was "to provide a suitable ancestral home for Tintin and himself to move into." To achieve this in terms of the plot, Hergé also details Haddock's ancestry, something Thompson regards as distinctive: "Haddock is the only regular character whose relatives turn up in the Tintin stories at all (if one discounts Jolyon Wagg and his dreadful family)." As Haddock's role grew, Hergé expanded his character, basing him upon aspects of friends,
Tintin (character) the firing squad (in "The Broken Ear") or too angry when informing Captain Haddock that he nearly cost them their lives (in "Explorers on the Moon"). However, as Michael Farr observed, Tintin has "tremendous spirit" and, in "Tintin in Tibet", was appropriately given the name Great Heart. By turns, Tintin is innocent, politically crusading, escapist, and finally cynical. If he had perhaps too much of the goody-goody about him, at least he was not priggish; Hergé admitting as much, saying, "If Tintin is a moralist, he's a moralist who doesn't take things too seriously, so humour is never far away
