O Pêndulo de Foucault

Tomás discovers Manuella's connections to Savigliano. Upon returning to Lisbon, he feels increasingly watched and suspicious of the Foundation, still without imagining that Diogo is watching him through video surveillance cameras and that Helena is working for the institution. Moliarti is unhappy with the direction of the investigation, which indicates flaws regarding the theory that Columbus was Genoese, but Tomás remains determined to see it through to the end. Meanwhile, during a new attack on the statue of Father António Vieira, Bruno and Afonso are saved by Tomás, who helps them escape from the police, putting his life in danger. Margarida undergoes urgent heart surgery, leaving Tomás and Constança shocked. The surgery turns out to be successful.
