Lucy O'Donnell Books in Order

Lucy O'Donnell is a newer series, and right now its shape comes from the opening novel, Murder at St. Hilaire. The setup is simple and strong. Lucy, a newly retired Boston police officer, heads to the Caribbean island of St. Hilaire for what should be an easy vacation. Instead, a young man is found dead, and the trip turns into a murder investigation almost at once.

Lucy is the kind of protagonist who brings professional instincts into places where she no longer officially has authority. She knows how to read a room, how to hear what people are not saying, and how quickly a tidy story can fall apart. Retirement matters here, too. She is no longer working the job, but she is still very much the person the job made her, which gives the series a grounded, practical feel.

The other key figure is Meilan Lin, the woman Lucy invites on the trip. Meilan is not just a sidekick. She is central to the story, because the murder investigation closes around her almost immediately. The dead man is a Chinese businessman, Meilan becomes a likely suspect, and the case reaches back into the history of the Chinese Cultural Revolution. That gives the book a second line of tension, personal history colliding with present danger.

The island matters.

St. Hilaire is a resort setting on the surface, but the mystery is not built around postcard scenery alone. The opening book ties the crime not just to the victim and the suspect, but also to the island's future. That means the series has room for local politics, business interests, outsider pressure, and the uneasy gap between what visitors see and what residents live with every day.

In tone, this looks less like a drawing-room puzzle and more like a contemporary mystery that uses character friction to keep things moving. Lucy's steady police experience meets Meilan's very different life history, and that contrast gives the story its energy. The stakes are personal from the start, because Lucy is trying to protect someone she brought into harm's way, while also figuring out how much of Meilan's past she truly understands.

With only one book out so far, the long arc is still taking shape. But the first novel suggests a series built around late-career reinvention, unlikely partnerships, and murders that connect the present to older political wounds. If that mix sounds good, Murder at St. Hilaire is the clear place to begin.
