"The Name of the Rose" by Umberto Eco

Umberto Eco's first novel quickly became an international sensation, selling 50 million copies worldwide.

Set in 1327, the book tells the story of Franciscans in a wealthy Italian abbey who become suspects of heresy, and of Brother William of Baskerville, who is sent to investigate.

Baskerville uses the logic of Aristotle, the theology of Aquinas, and the insights of Roger Bacon to decipher secret symbols and manuscripts.
