The Castafiore Emerald(Les Bijoux de la Castafiore)

Tintin and Captain Haddock are walking through the countryside of Marlinspike when they come across a Romani community camped in a garbage dump, and reunite a lost little girl named Miarka with her family there. The Romani explain that they are not allowed to camp anywhere else so Haddock invites them to the grounds of his estate, Marlinspike Hall.
