About the Alex Delaware series

Alex Delaware is a child psychologist in Los Angeles, semi-retired from private practice by burnout and a healthy trust fund, who keeps getting pulled back into consulting on cases -- almost always at the request of his closest friend, LAPD homicide detective Milo Sturgis. Jonathan Kellerman, himself a clinical psychologist before he became a novelist, builds each book around the psychology of victims, witnesses and killers as much as the crime itself: cult dynamics, childhood trauma, family pathology and the particular damage wealth and status can disguise in Los Angeles's private schools, gated enclaves and celebrity culture. Milo, a gruff, openly gay detective operating in a department not always comfortable with that, does the police-procedural legwork while Alex reads the people involved -- a duo dynamic that's held the series together since When the Bough Breaks in 1985.

The series is known for dense, dialogue-driven plotting, a strong sense of L.A. geography and class stratification, and a slow-burn central relationship: Alex's on-and-off romance with forensic sculptor Robin Castagna anchors the domestic side of the books across four decades. With over 40 entries and still going strong, it's one of the longest-running psychological crime series in the genre, appealing to readers who want their whodunits grounded in real clinical insight into why people do terrible things, alongside a satisfying, familiar investigator partnership.

Frequently asked questions

How many books are in the Alex Delaware series?

There are 41 novels as of Jigsaw (2026), published from 1985 to the present.

What order should I read the Alex Delaware books in?

Publication order, starting with When the Bough Breaks, gives the fullest picture of Alex and Milo's friendship, but each book's mystery is self-contained enough that you can start almost anywhere.

Is the Alex Delaware series finished?

No, it's ongoing. Jonathan Kellerman has published a new Alex Delaware novel almost every year since 1985, most recently Jigsaw (2026).

Do I need to read Jonathan Kellerman's other series first?

No. Kellerman's other work (including books co-written with his wife Faye Kellerman, or their son Jesse Kellerman's novels) is unrelated; Alex Delaware stands alone.

Is Alex Delaware a detective?

No -- he's a child psychologist who consults with the LAPD, primarily through his best friend, homicide detective Milo Sturgis, rather than a sworn police officer or private investigator.
