The Quintus Roman Thrillers by Neil Denby follow a Roman soldier named Quintus through six books published between 2023 and 2026. Each title corresponds to a Roman military rank: Legionary, Decanus, Optio, Centurion, Scutarius, and Speculator. As Quintus advances, the scope of his missions and the dangers he faces grow with each promotion.
The series combines historical detail about Roman military structure with thriller pacing and battlefield action. Denby uses the rank system as a framework for the overarching story, so readers experience the Roman army from the ground level up. The progression from infantry grunt to elite operative gives the series a strong forward momentum that carries across all six books.
