12 Best Jonathan Kellerman Books

The best Jonathan Kellerman books, ranked by how many expert sources recommend each one, with notes on who they suit and where new readers can start.

Our take

Jonathan Kellerman's crime novels pair the patient work of a psychologist with the questions a police investigation leaves unanswered. Most follow Alex Delaware and LAPD detective Milo Sturgis through Los Angeles, where family histories, professional secrets and money complicate the search for a killer. They suit readers who enjoy interviews, tangled motives and a friendship that develops across many cases.

The early novels give Alex's clinical work a prominent role. Blood Test and Over the Edge put vulnerable patients at the center, while Silent Partner makes the investigation more personal. Later entries offer different kinds of puzzles: Serpentine revisits a cold case, and The Museum of Desire begins with a deliberately baffling crime scene. Billy Straight shifts the focus to detective Petra Connor and a young witness. Expect disturbing violence, even when the familiar investigators make the reading feel comfortable.

Start with When the Bough Breaks to meet Alex and Milo, then follow the early books in publication order if their relationship draws you in.

The 12 books, ranked

Ranked by how many expert sources name each book. Ties go to the book more people recommend.

1

For newcomers who want to understand Alex and Milo's partnership before sampling later cases. Its focus on a child witness establishes Alex's role clearly, though the violence against children makes this a difficult introduction.

What it's about

Retired child psychologist Alex Delaware is asked to help a young witness to a double murder. Working with detective Milo Sturgis, he tries to recover the girl's memories while uncovering a conspiracy that connects the crime to his own past.

2

Over the Edge

Alex Delaware, Book 3

by Jonathan Kellerman1987

For readers who want Alex's work with patients to matter as much as the police investigation. It offers a stronger clinical connection than the later crime-scene puzzles, though its tangled accusations demand close attention.

What it's about

A former patient's desperate call brings Alex Delaware to a psychiatric hospital, but the young man has vanished. When police identify him as a suspected serial killer, Alex examines his troubled history to determine whether madness or manipulation explains the accusations.

3

Blood Test

Alex Delaware, Book 2

by Jonathan Kellerman1986

For readers who want to continue directly from Alex's debut and stay close to his work with children. The medical conflict gives his involvement a clear purpose, though the threatened child and family violence are unsettling.

What it's about

A gravely ill boy disappears from hospital after his parents refuse potentially lifesaving treatment. Alex Delaware and Milo Sturgis follow the family's trail, uncovering disturbing beliefs and violent secrets while racing to find a child whose survival depends on help.

4

Dr. Death

Alex Delaware, Book 14

by Jonathan Kellerman2000

For readers drawn to the moral questions around medicine and death. It gives Alex's psychological approach a particularly uncomfortable subject, but the mutilation and assisted-death material will be too much for some readers.

What it's about

The mutilated body of a physician associated with assisted deaths draws Alex Delaware into a disturbing investigation. As he examines the doctor's controversial work and personal history, the search for a killer raises increasingly troubling questions about motives and responsibility.

5

Monster

Alex Delaware, Book 13

by Jonathan Kellerman1999

For readers comfortable with gruesome crime who want a mystery rooted in psychiatric care. Its hospital setting puts Alex's expertise to work directly, though the extreme mutilation makes it a poor choice for sensitive readers.

What it's about

A confined psychiatric patient appears to predict murders outside his institution, baffling Alex Delaware and Milo Sturgis. Their investigation links mutilated victims, hospital secrets, and family histories while raising urgent questions about who is directing the violence.

6

Silent Partner

Alex Delaware, Book 4

by Jonathan Kellerman1989

For readers who want Alex to have a personal stake in the questions he asks. The emphasis on guilt and past relationships distinguishes it from the clinical cases, though the family secrets become complicated.

What it's about

Alex Delaware encounters former lover Sharon Ransom, who hints that she needs help, then dies in an apparent suicide. Driven by guilt, he investigates her life, uncovering buried family wounds and secrets beneath Southern California's wealthy social circles.

7

Time Bomb

Alex Delaware, Book 5

by Jonathan Kellerman1990

For readers who want Alex's psychology set against political extremism rather than a single troubled family. It broadens the early series' scope, though the school attack and conspiracy material make it a particularly uneasy read.

What it's about

After a teenage sniper attacks a school playground, Alex Delaware helps the traumatized children and questions the shooter's motives. A request from the teenager's father draws him into the dead youth's past, where disturbing patterns point toward a larger plot.

8

For readers who enjoy sorting out an elaborate crime-scene puzzle with Alex and Milo. The unusual arrangement offers more immediate mystery than Serpentine's old evidence, though the convoluted setup can overshadow the people involved.

What it's about

Four bodies are discovered arranged inside a limousine at a deserted Bel Air mansion, each apparently killed differently. With no clear connection between the victims, Alex Delaware and Milo Sturgis pursue a baffling crime marked by deliberate misdirection.

9

Billy Straight

Petra Connor, Book 1

by Jonathan Kellerman1998

For readers who want a break from Alex's viewpoint without leaving Kellerman's Los Angeles. The young witness brings a different emotional perspective alongside Petra Connor's police work, though his vulnerability makes for anxious reading.

What it's about

Twelve-year-old runaway Billy Straight witnesses a brutal murder in Griffith Park and flees into Los Angeles. Detective Petra Connor searches for both the killer and the frightened child, whose precarious life on the streets makes him an increasingly vulnerable witness.

10

Serpentine

Alex Delaware, Book 36

by Jonathan Kellerman2021

For readers who prefer patient reconstruction of the past to an urgent chase. Its cold-case structure offers a different rhythm from the early patient-centered novels, though the limited evidence means plenty of interviews and backtracking.

What it's about

A wealthy woman pressures the LAPD to reopen the decades-old killing of the mother she never knew. Alex Delaware and Milo Sturgis revisit a burned car, scarce evidence and failed investigations, finding that the past still conceals present-day danger.

11

The Murder Book

Alex Delaware, Book 16

by Jonathan Kellerman2002

For returning readers who want more of Milo's history and his place in the police department. It deepens the partnership beyond Alex's clinical perspective, though the personal background rewards familiarity with the series.

What it's about

An anonymous album of crime-scene photographs reopens a murder that haunted Milo Sturgis early in his career. With Alex Delaware's help, he revisits the killing and uncovers secrets reaching into Los Angeles's powerful circles across two decades.

12

Victims

Alex Delaware, Book 27

by Jonathan Kellerman2012

For readers who want the mental-health setting and a darker serial-killer investigation together. Alex's professional background gives it a different emphasis from the cold cases here, but the graphic violence makes it a demanding choice.

What it's about

A gruesomely staged murder is followed by similar killings with no obvious connection between the victims. Alex Delaware and Milo Sturgis pursue a cryptic clue through the mental-health system, including an institution linked to Alex's own professional past.
