An international sensation and winner of the Premio Strega and the Prix Médicis Etranger awards, this enthralling medieval murder mystery "explodes with pyrotechnic inventions, literally as well as figuratively" (The New York Times)The year is 1327. Benedictines 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. His tools are the logic of Aristotle, the theology of Aquinas, the empirical insights of Roger Bacon -- all sharpened to a glistening edge by wry humor and a ferocious curiosity. He collects evidence, deciphers secret symbols and coded manuscripts, and digs into the eerie labyrinth of the abbey, where "the most interesting things happen at night." "Like the labyrinthine library at its heart, this brilliant novel has many cunning passages and secret chambers . . . Fascinating . . . ingenious . . . dazzling." --Newsweek
