The Detective Galileo novels should ideally be read in publication order, as characters and relationships develop across the series. However, each novel works as a standalone mystery:
- The Devotion of Suspect X (2005) — The essential starting point. The novel that defines the series.
- Salvation of a Saint (2008) — Directly follows events from the first novel.
- A Midsummer's Equation (2011) — Galileo's most personal case.
- Silent Parade (2014) — A crossover event with Detective Kaga.
- Invisible Helix (2023) — The most recent translated installment.
The series concludes with Eternal Memory (2026), Higashino's final novel. Learn more →
