Henry Kimball / Lily Kintner Books in Order

The Henry Kimball / Lily Kintner books are Peter Swanson’s darkest, most tightly linked thrillers, circling two people who can’t quite escape each other. One is supposed to stand for the law, the other for everything the law can’t quite reach.

Henry Kimball first appears as a Boston detective in The Kind Worth Killing, investigating a violent case that begins with a chance meeting on a flight and ends with multiple bodies. By the time readers meet him again, in The Kind Worth Saving, he’s left the force, nursing old wounds and working as a low‑key private investigator who mostly takes on small domestic jobs.

Lily Kintner, meanwhile, is the series’ gravitational center. Brilliant, self‑contained, and quietly ruthless, she moves through the world with her own private code of justice. In The Kind Worth Killing she starts as a stranger in an airport bar and reveals, piece by piece, a past full of calculated violence. Swanson never turns her into a simple villain; she’s frightening, but she’s also observant, darkly funny, and always thinking three steps ahead.

Across the later books Lily and Henry keep crossing paths in new configurations. In The Kind Worth Saving, Henry is hired by Joan, a former student from his short stint as a high‑school English teacher, to look into her possibly unfaithful husband. What begins as routine surveillance leads him to a crime scene in an empty suburban house and a pattern of deaths that feels too orchestrated to be coincidence. When the case brushes up against old nightmares, Henry turns—reluctantly—to Lily for help.

A Talent for Murder widens the circle again. Here, a quiet New England librarian named Martha Ratliff starts to suspect that her traveling‑salesman husband might be connected to a string of women who have died under suspicious circumstances. Not sure whether she’s imagining things, she reaches out to Lily, an old grad‑school friend who once helped her escape an abusive boyfriend. Lily sees the situation clearly and pulls Henry back into the mix, setting off another round of investigation in which the hunters and hunted keep changing places.

Taken together, the series plays like a long argument about what justice looks like when the courts and the police can’t, or won’t, deliver it. Henry wants to believe in procedure and due process, but he’s haunted by the cases he’s mishandled. Lily believes some people simply deserve to die, and she’s willing to act on that belief. Their wary alliance gives the books an ongoing tension that goes beyond any single murder plot.

Each novel introduces new characters, fresh crimes, and its own stand‑alone mystery, so you can technically read them in any order. But starting with The Kind Worth Killing and moving through The Kind Worth Saving to A Talent for Murder lets you watch Henry and Lily’s strange orbit tighten over time and makes each hard choice they face feel that much sharper.
