A 19th Century Kilmurray Mystery Books in Order

The Kilmurray books take David DeLee's interest in policing and move it back to the very start. Set in 1845, they follow Sergeant Daniel Kilmurray and Patrolman William Hamon in the early days of New York City's paid Municipal Police force, when modern policing is still being invented on the job.

That matters because these stories do not lean on modern tools. No forensics lab. No databases. No easy chain of command that always works. Kilmurray and Hamon have to solve cases through interviews, observation, stubbornness, and a willingness to walk straight into places other people would rather avoid. The result is less gadget-driven mystery and more ground-level detective work.

The setting does a lot of heavy lifting. The Woman on Pier 29 begins with a body in the East River and pulls the investigation from the lower East Side piers to grand hotels and rough boarding houses. A Murder on Pearl Street sends Kilmurray and Hamon into Five Points and the Old Brewery, where violence is common and getting answers can be almost as dangerous as the crime itself.

These are shorter historical mysteries, but they do not feel slight. DeLee uses the city well, especially the gap between wealth and misery, order and chaos. You get the sense of a New York that is growing fast, crowded, and often lawless, with police trying to create structure in places that resist it.

Kilmurray himself is a solid anchor. He is practical, observant, and serious about the work, while Hamon gives him someone to test ideas against as the force finds its footing. Together they make the books feel like historical procedurals rather than costume pieces.

If you like mysteries where the setting really matters, this series is worth a look. It offers murders to solve, but also a glimpse of what crime fighting looked like before the systems we now take for granted even existed. That early, uncertain version of police work gives the books their bite.
