Dr. Katie LeClair Books in Order

The Dr. Katie LeClair Mysteries follow a doctor who is trying to put down roots, only to find that a quiet Michigan town has more secrets than she expected. Dr. Katie LeClair has spent years moving through medical school and training. When she settles in Baxter, outside Ann Arbor, she wants a home, a steady job, and a chance to build a life that is hers.

That plan does not last long.

In Unnatural Causes, Katie joins a family medical practice and begins to find her footing in Baxter. Then one of her patients dies in what appears to be a suicide linked to medication Katie supposedly prescribed. She does not remember writing the prescription, and the discovery that the death may be murder pulls her into an investigation far outside her usual duties.

Katie is not a police officer or a professional detective. Her strengths come from her medical training, her attention to people, and her refusal to ignore a question just because it is inconvenient. The series uses her work as a physician as more than a job title. Records, professional responsibility, patient trust, and the pressure of getting things right all shape the danger she faces.

Baxter is small enough for relationships to overlap. Friends, colleagues, patients, and old local stories can all become part of the same case. That gives the books a close-knit feel, but it also means Katie cannot easily leave a mystery at the office door. The people involved are often part of the community she has chosen as her new home.

The second book, Do No Harm, raises the stakes by connecting Katie to an old murder conviction, a missing former mentee, and a college student digging into Katie’s previous case. With Baxter preparing for its Halloween festival, Katie must sort through competing stories and decide whom she can trust before violence reaches closer to her.

These are small-town mysteries with a sharper edge than Eastman’s paranormal cozy books. The tone is suspenseful but character-focused, with medical details and local history adding texture rather than taking over the story. Katie’s growing relationships, including her place in the practice and her new romance, run alongside the investigations.

Start with Unnatural Causes. It establishes Katie’s move to Baxter, her work, and the first event that turns her from doctor into an unwilling sleuth. Do No Harm works best after it because it builds on the consequences of that first case and Katie’s increasingly complicated ties to the town.
