Undone (will Trent, #3)

This novel in the Will Trent series follows three protagonists whose lives converge around a serial abduction case in Atlanta, Georgia.

Henry and Judith Coldfield are driving home from their fortieth anniversary party near Conyers, Georgia, when their Buick strikes what Judith initially mistakes for a deer. The figure is a nude woman, severely bruised, with dried blood on her legs and a wound exposing bone. Two men from a passing car stop to help, one an off-duty EMT who begins administering aid.

Sara Linton, a former pediatrician and county coroner, works as an emergency room doctor at Grady Hospital in Atlanta. She relocated after her husband, police chief Jeffrey Tolliver, was killed three and a half years earlier, and she carries an unopened letter from the woman she blames for his death. Near the end of her shift, Sara treats Faith Mitchell, a thirty-three-year-old agent with the Georgia Bureau of Investigation (GBI). Faith's partner, Special Agent Will Trent, accompanies her. Sara diagnoses Faith with type 2 diabetes triggered by a pregnancy Faith has not disclosed to Will.

The woman from the road arrives by ambulance: emaciated, covered in electrical burns and shallow cuts, with signs of prolonged sexual assault. Will attempts to establish a dying declaration, a legal statement that would allow her last words to be admitted as evidence. The woman confirms her first name as Anna before losing consciousness. X-rays reveal her eleventh rib has been violently ripped from her body.

Will drives to the accident scene, where Rockdale County police refuse him access. He circles through the woods and discovers a plywood-covered underground cavern containing a bloodstained bed, chains, torture implements, and pages covered in the obsessively repeated sentence "I will not deny myself." Cut ropes and a broken tooth fragment beneath the bed prove a second victim was held there and escaped.

Will later finds a Florida driver's license belonging to Jacquelyn Zabel and discovers her body hanging upside down in a tree, her neck broken and a front tooth missing. Warm blood indicates she died very recently, possibly while searchers were nearby.

The next morning, Pauline McGhee, an interior designer, is abducted from a grocery store parking lot while reaching for her son Felix, who is standing beside her SUV with a stranger. A store manager finds the six-year-old sleeping alone in the car three hours later. Atlanta Police Detective Leo Donnelly contacts Faith because the missing mother matches the victim profile: midthirties, dark hair, successful, and socially isolated.

Will interviews Felix at Grady. The boy describes his mother's abductor as a man with dark hair, a mustache, and a suit, and reveals his mother warned him about a dangerous uncle he has never met. Meanwhile, the GBI medical examiner, Pete Hanson, conducts Zabel's autopsy with Sara assisting. The killer rendered Zabel blind, deaf, and mute by piercing her eyes with needles, puncturing her eardrums, and pouring drain cleaner down her throat. Sara determines the knife wound in Zabel's chest was self-inflicted: Unable to perceive the searchers, Zabel ended her own life rather than risk recapture. Eleven industrial trash bags are found stuffed inside Zabel's body; Sara finds the same inside Anna, causing the infection that nearly killed her.

Sara proposes that the number 11 has biblical significance, noting that after Judas betrayed Christ, only 11 apostles remained, and Easter is approaching. Leo Donnelly traces Pauline's real identity as Pauline Agnes Seward, who vanished from Ann Arbor, Michigan, 20 years ago on Easter Sunday. At Pauline's office, Faith discovers pro-anorexia content and a notebook filled with "I will not deny myself," matching the pages found in the cave. Zabel's sister confirms Jackie also struggled with anorexia. Eating disorders become the thread connecting the victims: isolated, self-punishing women with similar builds.

A fourth victim, Olivia Tanner, a bank vice president, is reported missing. Her brother reveals their father sexually abused her, triggering severe anorexia. In a vacant house behind Olivia's property, Will and Faith find evidence of prolonged surveillance. AFID dots, the tiny identifying confetti ejected by a Taser cartridge, trace back to a purchase under the name "Pauline Seward," proving the killer knows Pauline's original identity and has planned the abductions for months.

Anna Lindsey, the first victim, regains consciousness and reveals she has a six-month-old son at her penthouse. Will and Faith race there, finding the luxury apartment trashed. Will loses control and assaults the building's indifferent doorman. They find baby Balthazar in a recycling bin, dehydrated but alive. Will's boss, Amanda Wagner, the GBI's deputy director, suspends him but orders him to keep working. Sara tells Will the choice not to cross that line again is his to make. He reveals he was found as an infant in a kitchen trashcan, a detail that resonates with the killer's use of trash bags to convey the victims were worthless. Anna refuses to cooperate with investigators.

In parallel chapters, Pauline endures captivity in a basement alongside Olivia. The two women recognize each other from the pro-anorexia chat room. Pauline kicks through the sheetrock wall but finds chicken wire behind it. They begin gnawing at the wire with their mouths, taking turns in 200-second shifts.

The case breaks open when Will visits the Coldfields' retirement cottage and learns their son Tom coordinates donations for the Fred Street Women's Shelter. Every victim connects to the shelter: Olivia's bank was a donor, Anna's law firm did pro bono work, Jackie donated her mother's belongings, and Pauline recommended the shelter to clients online. Tom met all the victims through this access.

Faith arrives at Tom's house for a routine interview and hears a woman screaming through a floor grate in the bathroom. Tom's wife Darla fires a Taser at her through a hidden door; Faith dodges and returns fire. Tom grabs Faith from behind, but Pauline, who has broken out of the basement, bursts through the door and wraps her chained hands around his throat. Faith forces Pauline to release Tom at gunpoint. Pauline reveals that Tom is her brother.

At the Coldfields' cottage, Judith stabs Will in the back when he reaches for the phone. Amanda shoots Judith through the window, saving his life.

Three days later, Pauline tells the full story. Her uncle raped her starting at age three; when she told her grandmother, the family blamed her, and her mother Judith sided with them. When Pauline was 15, her 11-year-old brother Tom became obsessed with her and began abusing her best friend Alexandra McGhee, who resembled Pauline. When the girls tried to go to police, Tom imprisoned both in a cave he had dug. After his arrest, Judith convinced the court to let the family relocate. Alexandra later died by suicide. Eighteen months before the current crimes, Tom found Pauline by cold-calling her office about the shelter. Pauline unknowingly connected all the victims to her brother by recommending the shelter in the chat room, giving Tom access to vulnerable women who resembled his sister. The FBI takes over the case, finding similar pairs of victims in 12 of the 16 cities where Tom lived. Henry Coldfield dies of a heart attack upon learning the truth.

In the epilogue, Sara takes the letter from her purse. It is a confession from Lena Adams, the detective whose actions led to Jeffrey's murder. Sara acknowledges that nothing in it will bring Jeffrey back or grant her peace. Knowing this, she sits down and reads it anyway.
