The Name of the Rose

Novel by Umberto Eco, published in Italian as Il nome della rosa in 1980. Although the work stands on its own as a murder mystery, it is more accurately seen as a questioning of "truth" from theological, philosophical, scholarly, and historical perspectives. The story centers on William of Baskerville, a 50-year-old monk who is sent to investigate a death at a Benedictine monastery. During his search, several other monks are killed in a bizarre pattern that reflects the Book of Revelation.
