The Name of the Rose, by Umberto Eco.
Really enjoyed ‘Foucault’s Pendulum’ last year by the same author, was in a bit of a reading slump though so it took me ages to get through this given how dense the writing is with all the historical lore and whatnot.
If you are familiar with his work, you’ll know the plot takes a firm back seat to his he characters having lengthy conversations about the historical aspects of the story. Ode to the Eco being a historian and professor of semiotics (the study of symbols)
The main plot follows a monk named William of Baskerville (who is somewhat based off Sherlock Holmes) and his scribe & novice ‘Adso’ (from who’s perspective the story is told) as they investigate a series of murders at a monastery in Northern Italy during the 14th century.
Eventually they are drawn into the strange goings on around the monastery at night including in the mysterious labyrinthine library in the monastery’s aedeficium.
I quite enjoyed this despite the slog, a lot of the dialogue centres around stuff like the ideological conflict between the Franciscan and Benedictine monks and debates over whether Jesus ever laughed or not (!!) and can get a little bit tiring as a result. The he main murder plot, when it finally turns up, is great though!
