L'Affaire Tournesol
Tintin joins his friends a few days later, where he points out to Haddock and Calculus that their villa is bugged. He recognises one of the staff as Pablo, a man who had saved his life in "The Broken Ear". From Pablo, Tintin learns that the entire scenario is a plot organised by Colonel Sponsz, a figure in the Bordurian military who is assisting Tapioca's government in order to gain revenge against Tintin for the events of "The Calculus Affair".
