The Secret of the Unicorn was one of the first truly great Tintin adventures and Herge's personal favorite, combining a puzzling mystery with a ripping pirate yarn. When Tintin finds a magnificent model ship in the street market, his attempt to buy it for Captain Haddock leads him on a trail of pickpockets, burglars, and secret treasure... Only it isn't just any model ship-it's the Unicorn, carved by one of Haddock's ancestors, and it holds a clue to finding pirate treasure!
