Templar Detective Books in Order

The Templar Detective books ask a fun question and take it seriously: what would a detective story look like in a world before detectives were really a thing? Kennedy answers by dropping us into the late medieval world of Sir Marcus de Rancourt, a wounded Templar knight who comes home expecting grief and hard choices, then finds himself pulled into murder, intrigue, and the kind of conspiracies that can shift power across a kingdom.

Sir Marcus is the anchor here.

At the start of the series he returns home to find his sister dead and her children orphaned. He decides to stay and raise them, with his loyal sergeant and squires choosing to remain by his side. That gives the books a grounded domestic core that plays nicely against the larger stakes. Marcus is not just fighting for an order or a cause. He is trying to build a life after war, and the cases keep interrupting that effort in increasingly dangerous ways.

The setting matters a lot. These stories move through a world shaped by the Templars, the Church, noble scandal, local fear, and fragile justice. One case may begin with a child's accusation, another with a famous affair, a missing sergeant, a suspected exorcist, a broken code, a plague scare, or stolen children. But they all work from the same pressure point: Sir Marcus is trying to do right in a system where power can easily crush truth.

The tone is historical thriller first, mystery second, with a modern sense of pace. Kennedy does not write these as dusty costume dramas. The chapters move quickly, the dialogue is accessible, and the investigations are built around motive, testimony, reputation, and danger rather than forensic detail. That keeps the books approachable even if you do not normally read historical fiction.

Faith is part of the series, but not in a preachy way. Marcus is a believing man, and the Templar identity matters, yet the books are just as interested in the gap between sacred language and human behavior. Loyalty, honor, secrecy, and corruption all sit right next to one another here. That tension is where many of the best scenes live.

If you want a mystery series with swords, abbeys, scandal, and a hero who would really prefer a quiet life but never quite gets one, this is a good fit. Start with The Templar Detective. It gives you the family setup, the key supporting relationships, and the exact flavor of historical intrigue the rest of the series keeps building on.
