The Butcher Legacy

The third installment in the Dr. Wren Muller series picks up approximately two months after the murder of Wren's husband, Richard. Wren, a forensic pathologist in New Orleans, continues working at the morgue while grieving. The imprisoned serial killer Jeremy Rose, whom the press dubbed "the Butcher," is connected to Richard's death, but key evidence from the crime scene, including partial fingerprints and a dark facial hair on the syringe used to inject Richard with succinylcholine, a paralytic drug, did not match Rose, suggesting an accomplice. Suspicion falls on Pastor Philip Trudeau, Jeremy's childhood friend, in whose Massachusetts basement Jeremy was found hiding.

Detective Lucas Hart, a newcomer to the Kingsborough Police Department in western Massachusetts, attends one of Trudeau's church services to observe him. Hart notices unsettling details, including stained glass windows Trudeau crafted depicting figures with empty, pupilless eyes. Their exchange after the service is cordial but charged with mutual suspicion. Hart has been investigating inconsistencies in how the department handled the Rose case: The Kingsborough PD refused to investigate Trudeau, and evidence from Richard's murder scene was either ignored or lost. Hart becomes the inside contact for Detective John Leroux of the New Orleans Police Department (NOPD), one of Wren's closest allies.

Leroux is pursuing two missing persons cases: Melissa Evans and Beth Landry, both young women who stayed at Resurrection House, a shelter run by Sister Agatha Moreau. Hart reports that Trudeau has vanished from his church, claiming a last-minute mission trip with no record of him on any international flight. He also notes that several young women from Trudeau's congregation have disappeared over the years, all single and lacking strong community ties.

At the morgue, Wren asks Wyatt DuPont, a mortician from Walden Funeral Home, about his unusual technique of placing two extra diagonal needle injector pins to keep a deceased person's mouth closed. This seemingly minor detail later proves crucial. Wren also calls Officer Maya Rodriguez, a recent NOPD transfer whose family practices brujería, a Latin American tradition of cleansing rituals and protection spells. Maya warns that a cleansing ritual would also remove Richard's lingering spiritual presence, a realization that devastates Wren.

Trudeau's chapters reveal a predator hiding behind pastoral authority. Under the guise of private counseling, he isolates vulnerable women from his congregation, drugs them with tea laced with angel's trumpet, a toxic plant that induces hallucinations and renders victims pliable, and brings them to a hidden cabin in remote hills where he forces confessions and kills them. His former psychologist, Dr. Gabriel Price, later reveals that Trudeau was brought in at age six for killing animals and that as he approached adolescence, he confided violent fantasies about girls and drew pictures of them with slit throats and scratched-out eyes. Dr. Price's attempts to report his concerns were blocked by Trudeau's father, Sebastian Trudeau, a federal judge who prioritized reputation above all.

Wren and Leroux visit Jeremy at Dead Creek Penitentiary. He addresses Wren by her former name, "Emily," the identity she used before changing her name to distance herself from their shared college past. Wren turns his tactic against him, suggesting his obsession with her former identity caused his downfall. Jeremy taunts them with claims about Richard's last words but refuses to answer questions about the unmatched evidence. Despite the emotional toll, Wren recognizes that Jeremy recycled his manipulations by the end of the visit, suggesting he is more vulnerable without careful planning.

An anonymous tip leads Leroux and his partner, Detective Will Broussard, to an unlicensed pop-up haunted house at an old farm. Inside, they discover Melissa's body posed as a kneeling nun, her eyes carved out and dried blood painted in tear-like streaks down her cheeks. Real human body parts from multiple other victims are staged as props in adjoining rooms. Melissa's personal journal, recovered earlier from Resurrection House, reveals she had been meeting a man named Jeremy who made their encounters feel divinely orchestrated. Wren's autopsy confirms strangulation as the cause of death and orders a full toxicology panel.

During a second prison visit, Jeremy hints that Trudeau has killed before, is in Louisiana, and that victims will be found somewhere religious or sacred. Wren notices a guard named McCormick handling Jeremy with unusual gentleness and exchanging covert glances with him. DNA analysis from the crime scene returns a partial match for Jeremy, and Leroux deduces that Jeremy bribed McCormick to smuggle his blood out for planting at the scene.

Dr. Price then reveals that Jeremy and Trudeau are half brothers. Mona Rose, Jeremy's mother, had a son approximately a year before Jeremy, fathered by Sebastian Trudeau. The baby was taken in by Sebastian's family to avoid scandal, and neither man knows about their biological relationship. Wren makes a critical connection: Half siblings share approximately 25 percent of their DNA, explaining why the crime scene blood partially matched Jeremy. National database results confirm a second partial match for Philip Trudeau, giving investigators grounds to pursue him.

Kathryn Trudeau, Philip's estranged ex-wife, provides crucial evidence. She secretly installs a tracker on Philip's phone and places a GPS device in his wallet. The tracking data places Philip in Salem on the night Andrea Meyers, a woman with whom he had an affair, was murdered, and at the rental house where Richard was killed. However, the tracker also shows Philip remained in Massachusetts too recently to have killed Melissa, eliminating him from the New Orleans crimes while confirming his presence at Richard's murder scene.

The breakthrough comes when Wren's technician discovers that Melissa's jaw was sealed with super glue and held by two pairs of diagonal needle injector pins, the same signature technique Wyatt DuPont uses. A search of Wyatt's abandoned home yields human bones, evidence of grave robbing that explains the older body parts, and letters from Jeremy Rose. The letters reveal that Jeremy directed Wyatt to kidnap young women, stage religious crime scenes to frame Trudeau, and plant a vial of Jeremy's blood at the scene. Jeremy intended the blood to sow confusion, unaware it would partially match Philip's DNA and accidentally strengthen the frame. The letters also show Wyatt was always meant to take the fall after a longer spree, but he proved too reckless.

Leroux and Broussard arrest Wyatt at a masquerade party where he is dressed as a priest and eerily calm. During interrogation, Wyatt refuses to reveal Beth's location, spouting biblical quotations. Maya identifies one verse as coming from the Book of Jude and locates a clearing called Jude's Hollow near the original crime scene. During a search, Leroux and Wren hear faint moans and find Beth strung up by her wrists from a tree branch. She is alive but severely injured, with a missing tooth, a broken tooth, broken fingers, a fractured rib, and signs of prolonged assault. Wren holds her while Leroux cuts the rope.

At a final prison visit, Wren tells Jeremy he has a half brother, Philip Trudeau. For the first time, Jeremy's composure cracks as he processes that his mother gave away another child before him. Leroux calls Jeremy a standard case study driven by his mother while describing Philip as something far more frightening by nature. Wren waves goodbye with a mocking reference to Norman Bates.

Hart contacts Leroux with updates: He follows Kathryn's tracker data to Trudeau's cabin, discovers bloodstains and a chair nailed to the floor, and pressures the Kingsborough PD into testing the fingerprints from the syringe used to kill Richard. Meanwhile, Jeremy calls Wren's personal cell phone from prison, taunting her and implying he has contacts beyond Wyatt with access to her information. Wren spirals briefly into panic before regaining control, reminding herself Jeremy is powerless behind bars.

Trudeau, unhinged after Hart's discovery of his cabin, flies to Louisiana and breaks into Leroux's home, attacking Leroux's husband, Andrew, with a knife. When Trudeau lunges at Andrew, Leroux shoots him in the neck. In a moment of catharsis, Leroux tells Philip that Kathryn gave him up and lets him bleed out. Wren arrives to process the scene, examines Philip clinically, and pronounces him dead.

In the epilogue, Jeremy receives a smuggled letter from an unnamed follower who attended the masquerade and declares readiness to step into Wyatt's role. A guard tells Jeremy his brother is dead. Jeremy shows no emotion and returns to writing his response, continuing to cultivate followers from behind bars. The novel closes with the clear implication that Jeremy's network remains active and the threat is far from over.
