Sue Grafton Books in Order: The Complete Kinsey Millhone Guide (2026)

Sue Grafton’s Kinsey Millhone is one of the defining detectives of modern crime fiction — a wry, self-sufficient private investigator who, across twenty-five novels, helped establish the female PI as a central figure in the genre. The “Alphabet” series, from A Is for Alibi (1982) to Y Is for Yesterday (2017), is among the most beloved and satisfying reading projects in all of mystery fiction. This guide lays out every Kinsey Millhone novel in order, flags the standouts, and explains why the alphabet ends one letter short.

The series ends at Y. There is no Z — see below.

Where to Start

Start at the beginning, with A Is for Alibi. It introduces Kinsey Millhone reopening an eight-year-old poisoning case, and it establishes everything the series runs on: the dry, self-deprecating first-person voice, the fictional Santa Teresa setting, and the lean, character-driven style. The early-to-middle entries are widely considered the strongest, so beginning at the start rewards new readers quickly.

Every Kinsey Millhone novel is built to function as a standalone, so you can dip in almost anywhere. But the series rewards sequence: Kinsey’s life develops across the books, her recurring relationships (especially with investigator Robert Dietz, introduced in G Is for Gumshoe) gain weight, and the slow revelation of her family history — beginning in J Is for Judgment — gives the later novels a cumulative emotional depth.

The Standout Entries

Beyond the strong early run, several novels stand apart:

• Q Is for Quarry (#17): a moving, elegiac cold case based on a real unsolved murder, pairing Kinsey with two dying retired cops determined to give a forgotten Jane Doe her name.
• T Is for Trespass (#20): one of the most chilling entries, a slow-burn thriller of elder abuse told partly through the eyes of a predatory caregiver.
• O Is for Outlaw (#15): the most personal novel, digging into Kinsey’s first marriage and the betrayal she may have committed.
• M Is for Malice (#13): a rich, melancholy family mystery, and a key entry for Kinsey’s romance with Dietz.
• K Is for Killer (#11): the darkest, most noir-tinged entry, ending on a morally troubling note.

The Late-Period Experiments

For the first eighteen novels, the series was narrated exclusively in Kinsey’s first-person voice. Beginning with S Is for Silence (#19), Grafton began breaking that pattern, interleaving multiple viewpoints and dual timelines — a structural ambition she carried through U Is for Undertow, V Is for Vengeance, and the final books. That willingness to experiment, nineteen books into a hugely successful series, is part of why the Alphabet never grew mechanical.

Why the Alphabet Ends at Y

Sue Grafton always intended to finish the series with a twenty-sixth novel, Z Is for Zero. She never got the chance. Grafton died of cancer in December 2017, only months after publishing Y Is for Yesterday. Her family announced that there would be no Z, and that no other writer would be allowed to continue Kinsey’s story. As her daughter put it, “the alphabet now ends at Y.” It is a poignant end for a series defined throughout by its author’s integrity — Grafton famously refused even to sell the film and television rights, determined to protect Kinsey from adaptations she could not control.

That unintended finality gives Y Is for Yesterday an added weight. Happily, it is a strong entry — a dual-timeline prep-school mystery that resolves the serial-killer threat seeded in X — and a fitting, if bittersweet, farewell to one of crime fiction’s great detectives.
