The name of the Rose

The Name of the Rose by Umberto Eco

The year is 1327. Franciscans in a wealthy Italian abbey are suspected of heresy, and Brother William of Baskerville arrives to investigate.

When his delicate mission is suddenly overshadowed by seven bizarre deaths, Brother William turns detective. William collects evidence, deciphers secret symbols and coded manuscripts, and digs into the eerie labyrinth of the abbey where extraordinary things are happening under the cover of night.
