In Newton, Massachusetts, a quiet suburb outside Boston, a fourteen-year-old boy named Ben Rifkin is found stabbed to death in a wooded park.
The case lands on the desk of Andrew Barber, a veteran First Assistant District Attorney who has spent his career putting criminals away.
Then the evidence turns toward his own son.
William Landay’s Defending Jacob follows a prosecutor who becomes a father first, tracing how a single murder charge dismantles a family, a career, and a community.

Defending Jacob Book Summary
Spoilers ahead. This section recounts the main events of the novel, including the ending.
Part One: The Murder in Cold Spring Park
On the morning of April 12, 2007, fourteen-year-old Ben Rifkin is found dead in a gully in Cold Spring Park, a wooded shortcut students use on the way to McCormick Middle School.
He has been stabbed three times with a serrated blade, one wound piercing his heart.
Andy Barber leads the homicide investigation for Middlesex County alongside Lieutenant Detective Paul Duffy of the State Police.
Their first focus is Leonard Patz, a twenty-six-year-old registered sex offender living in apartments adjacent to the park.
Patz denies involvement, and no physical evidence ties him to the scene. Meanwhile, a Facebook memorial page for Ben becomes a hub of teenage gossip, revealing that Ben had bullied several classmates, Jacob Barber among them.
Andy searches Jacob’s bedroom and finds a large hunting knife hidden under his socks. Jacob claims he bought it for no particular reason and never used it. Fearing what investigators would assume, Andy disposes of the knife in a commercial Dumpster.
Days later, the state crime lab isolates a thumbprint pressed into Ben’s blood on the plastic tag of his sweatshirt. The print matches Jacob Barber.

Part Two: Indictment and the Family Secret
District Attorney Lynn Canavan removes Andy from the case and hands the prosecution to Neal Logiudice, Andy’s ambitious former protégé.
Jacob is arrested after hiding in Cold Spring Park, telling officers he had found Ben’s body and tried to help before panicking and running.
Andy hires veteran defense attorney Jonathan Klein. Jacob is released on $10,000 bail, and the family returns home to find “MURDERER WE HATE YOU” spray-painted across their house.
That night, Andy tells his wife Laurie a secret he has kept for their entire relationship. His great-grandfather was a convicted rapist and attempted murderer. His grandfather killed a man with a knife during a road-rage fight.
His biological father, William “Bloody Billy” Barber, is serving life without parole in Connecticut for the 1960 murder-rape of a young girl. Laurie is devastated, and she begins to question whether Jacob inherited something from that lineage.
Klein retains Dr. Elizabeth Vogel, a forensic psychiatrist who specializes in behavioral genetics, to evaluate Jacob and test for the MAOA gene variant linked in some research to impulsive aggression.
Prosecutors meanwhile uncover a story Jacob posted on an S&M fantasy site called “The Cutting Room,” describing a murder that mirrors Ben’s with disturbing accuracy.

Part Three: The Trial
The trial of Commonwealth v. Jacob Barber opens in Cambridge before Judge Burt French. Logiudice argues that Jacob is a cold, calculating killer who used his knowledge as a prosecutor’s son to cover his tracks. Klein counters that the case rests entirely on assumptions.
Witnesses establish the timeline and the physical evidence. Dog walker Sam Studnitzer recalls hearing a boy cry out, “Stop, you’re hurting me,” in the woods around 8:20 that morning.
Detective Duffy testifies about the absence of blood on Jacob’s clothing when he arrived at school and about the “Cutting Room” story. Jacob’s former best friend, Derek Yoo, delivers damaging testimony about the knife, a spot of blood on Jacob’s hand, and the link Jacob sent him.
During cross-examination, Logiudice crosses a line by asking about Andy’s father’s murder conviction, suggesting Jacob is a natural-born killer. Judge French sustains the objection but denies a mistrial.
Outside court, Andy tracks down Leonard Patz, who says Logiudice told him not to speak with Andy. Andy also receives a collect call from his imprisoned father, Billy, who expresses keen interest in his grandson’s trial.
Soon after, an aging mob enforcer named James “Father” O’Leary begins appearing near the Barber home and the courthouse.
Part Four: The Confession and the Aftermath
On the sixth day of trial, Leonard Patz is found dead in his apartment, hanged from the ceiling in an apparent suicide. A handwritten note beside his body contains a detailed confession to Ben Rifkin’s murder.
Handwriting experts verify the note. District Attorney Lynn Canavan files a nolle prosequi, and Judge French discharges Jacob in open court, declaring him a free man.
The Barbers travel to a resort in Jamaica to recover. There, Jacob meets a fourteen-year-old girl named Hope Connors, introducing himself as “Jacob Gold.” On the family’s final afternoon, Hope disappears.
When Jacob reaches the beach, Laurie notices brownish-red spatters on his swimming trunks. Andy tells him to jump into the ocean to wash them clean.
Seven weeks later, Hope’s decomposed body washes ashore. Authorities rule the death a drowning, though rumors persist that her windpipe was crushed before she entered the water.
Laurie’s mental state collapses. She becomes convinced that Jacob killed Ben Rifkin, killed Hope Connors, and cannot be redeemed. Andy visits Billy Barber in prison and learns the truth.
Billy had used his prison connections to send O’Leary into Patz’s apartment, force him to write the confession at gunpoint, and then hang him. Jacob’s legal exoneration rested on a murder arranged by his grandfather.
On the morning of March 19, 2008, Laurie takes Jacob out for breakfast. On the Massachusetts Turnpike, she unbuckles her seatbelt, accelerates the family’s minivan past 95 miles per hour, and drives into a concrete bridge abutment.
Jacob, unbuckled in the backseat, dies instantly. Laurie survives with catastrophic injuries and remains hospitalized in critical condition.
The novel closes in a grand jury room in April 2008, where Neal Logiudice is seeking to indict Laurie for her son’s murder.
Andy testifies that the crash was an accident caused by slick roads and that he has never heard of Father O’Leary.
