The Castafiore Emerald #[nn]

This volume collects the complete story of 'The Castafiore Emerald,' the 21st album in the Adventures of Tintin series, originally serialized in 1961-1962. In this tale, the famous opera singer Bianca Castafiore visits Marlinspike Hall, leading to a mystery involving a missing emerald and a series of comic misunderstandings. The story is notable for its departure from the series' usual globe-trotting adventures, taking place entirely at the château and featuring a more dialogue-driven, character-focused plot by Hergé.
