The Templar Detective and the Sergeant's Secret is the third adventure of Sir Marcus, a Templar Knight with a keen investigative mind that seems to always end up solving mysteries. Again, J. Robert Kennedy delivers a compelling blend of historical mystery and thrilling suspense that draws the readers into a world of medieval intrigue and hidden agendas. The author masterfully crafts a complex plot, weaving together clues, red herrings, and historical detail to create a truly immersive experience. The mystery itself is well-paced, and the bantering between the templar friends/brothers is fun and lighthearted. As the previous two books, I find this book a thoroughly enjoyable and engaging read.
