If you were captivated by the intricate web of secrets and parallel investigations Brother William pursues in The Name of the Rose, you'll find Foucault's Pendulum equally engrossing. Eco again delivers a labyrinthine plot, this time following three editors in Milan as they invent a conspiracy—only to become entangled in real danger. The story is layered with historical puzzles, cryptic manuscripts, and a dizzying interplay between reality and fiction, echoing the intellectual puzzles and depth that made your previous read so memorable.

If you loved the richly atmospheric medieval abbey and the meticulous historical detail Eco brings to 14th-century Italy, you'll be swept away by An Instance of the Fingerpost. Set in 17th-century Oxford, Pears crafts an equally immersive world—full of scholars, intrigue, and period-accurate customs. The book's deep dive into the politics, science, and daily life of Restoration England will satisfy your craving for a setting so vivid you can almost smell the parchment and candle wax.

If you appreciated the way The Name of the Rose delved into questions of faith, knowledge, and the nature of truth—especially through Brother William's debates and reflections—then The Secret History will resonate with you. Tartt's novel follows a group of classics students at an elite college as their intellectual pursuits spiral into obsession and crime, raising profound philosophical questions about morality, guilt, and the limits of knowledge.

If you were drawn to the way The Name of the Rose weaves puzzles within puzzles and builds suspense through lost manuscripts and coded texts, you'll be captivated by The Shadow of the Wind. Here, young Daniel discovers a mysterious book in postwar Barcelona, leading him into a labyrinth of secrets, forgotten authors, and literary intrigue. The multi-layered mystery and the love of books at its heart will appeal to fans of Eco's clever narrative games.

If Brother William's methodical logic and Sherlockian investigation drew you in, you'll relish The Daughter of Time. Inspector Grant, confined to a hospital bed, takes on the cold case of Richard III and the Princes in the Tower—solving a centuries-old mystery with sharp intellect and relentless curiosity. The blend of historical research and detective work will strike a familiar (and satisfying) chord.
