The name of the rose

The year is 1327. Franciscans in a wealthy Italian abbey are suspected of heresy, and Brother William of Baskerville arrives to investigate. His delicate mission is suddenly overshadowed by seven bizarre deaths that take place in seven days and night of apocalyptic terror. The body of one monk is found in a cask of pigs' blood, another is floating in a bathhouse, still another is crushed at the foot of a cliff.
