CHAPTER TWENTY-THREE
Vaughn drove like a woman who’d memorized every pothole between the precinct and the east side of Duluth, which she probably had.
The unmarked sedan ate the distance in sharp turns and controlled acceleration, the pine air freshener swinging from the rearview like a metronome counting down something neither of them wanted to name.
Isla rode with her hand on the door grip and her weapon checked and her mind running calculations she couldn’t yet finish—how long since DiMaggio’s call, how far to Skelling’s address, how much time a man like Palmer would need.
A man like Palmer. She was building the profile in real time, assembling it from the fragments DiMaggio had given them and the shape of the pattern that had finally declared itself.
A local historian. Genealogical researcher.
Soft-spoken, pleasant, knowledgeable—the kind of person who faded into the background of any room he occupied, who people trusted precisely because he seemed so thoroughly harmless.
He’d had access to the renovation plans through his role as exhibit consultant.
He’d had proximity to every victim’s ancestry disclosure through the same shared workspace that had made those disclosures possible.
And he’d had eight months on the project to watch, and listen, and choose.
"Palmer's been on the distribution list the entire time," Vaughn said, reading Isla's silence.
"His name was on the board. I interviewed him in the first round, two days after Lane.
He was cooperative, polite, gave me forty-five minutes and a detailed account of his movements. " Her jaw tightened. "I cleared him."
"So did I." Isla had reviewed every interview transcript Vaughn had compiled. Palmer’s had been unremarkable in the way that only the most careful subjects managed—no inconsistencies, no nervous tells, no gaps that invited further scrutiny. He’d been invisible in the data the same way he was invisible in a room.
"He fits. The weapons knowledge, the building access, the historical expertise—he’d know exactly which weapon to pair with which era, which space.
The exhibits were his narrative. He was writing the story the building was supposed to tell. "
"And now he’s writing a different one." Vaughn took the turn onto Skelling’s street and Isla saw it immediately—Skelling’s house, a modest Cape Cod set back from the road with a bare front yard and a driveway holding two vehicles.
A dark minivan—likely Derek Skelling’s, except Derek and the kids were at a movie.
And a silver sedan parked behind it, tucked close, like a guest who intended to stay.
"Second car," Isla said.
"I see it." Vaughn killed the headlights and pulled to the curb three houses down.
They were out of the car in the same motion, Vaughn reaching for the radio on her belt to call for backup while Isla drew her weapon and started toward the house at a pace that was faster than a walk and slower than a run—the controlled approach of someone who needed to get there now but needed to get there capable of acting when she arrived.
The house was lit from within—warm lamplight through the ground-floor windows, a fainter glow from the second story. Normal from a distance. A home on a Saturday night.
Then the glass broke.
It came from the second floor—a sharp, bright sound that split the quiet of the residential street like a gunshot. Not a window shattering outward in an explosion but the smaller, more desperate sound of glass being broken by something thrown from inside. And then the scream.
"Help! Someone help me—he’s in the house!"
A woman’s voice, high and ragged and unmistakable in its terror, pouring through the broken window into the cold night air.
Isla ran.
The front porch, three steps. The door was closed and locked.
Vaughn was right behind her, radio abandoned, and the detective didn't hesitate—she planted her foot and drove her boot into the wood beside the deadbolt with the focused, efficient violence of a woman who’d done this before and knew exactly where the frame was weakest. The door held for one kick, splintered on the second, and swung inward on the third with a crack that sounded like a small bone breaking.
Isla went through first, weapon raised, the muscle memory of a hundred room entries overriding everything else—fear, adrenaline, the voice still screaming from upstairs.
The living room opened in front of her: lamplit, warm, a couch with throw pillows, a coffee table with a half-finished puzzle.
Domestic. Ordinary. Except for the overturned end table near the hallway and the gouge in the hardwood floor where something sharp had scraped across the surface in a long, deliberate arc.
"FBI!" Isla’s voice filled the house with the particular authority she’d spent a career developing—loud enough to be heard on both floors, controlled enough to convey that the person behind it was not going to negotiate. "Raymond Palmer, this is the FBI! Put down the weapon!"
Silence from the ground floor. The screaming upstairs had stopped at the sound of the door coming in, replaced by a different sound—a woman’s voice, muffled by a closed door, calling down: "He’s up here! He’s on the second floor!"
Vaughn peeled right, moving through the ground floor with her weapon up and her back to the wall—kitchen, dining room, clearing each space with the quick, thorough sweeps of a detective who understood that the most dangerous room was always the one you hadn’t checked yet. Isla took the stairs.
She climbed fast, weapon leading, her back pressed to the wall of the stairwell where the angle gave her partial cover.
The second floor was a short hallway—three doors visible, two open, one closed.
The closed door was at the far end, and from behind it came the sound of running water and a woman’s breathing, harsh and fast.
"Skelling! It’s Agent Rivers, FBI. Are you hurt?"
"No—the bathroom—I’m locked in the bathroom. Palmer’s here, he has a knife, I don’t know where he—"
The closet door to Isla’s left exploded open.
Palmer came out of it the way a man comes out of a foxhole—low, fast, committed to the attack in a way that left no room for retreat.
He’d been waiting. Standing in the dark of a hallway linen closet, breathing quietly, listening to her footsteps on the stairs and timing his moment with the patience of a man who understood that history was a matter of choosing when to act.
The trench knife was in his right hand, the spiked knuckle guard wrapped around his fingers, and he drove it toward Isla’s midsection in the same short, economical thrust he’d used on Marissa Skelling twenty minutes earlier.
Isla’s training saved her life, and her reflexes saved everything else.
She pivoted left, twisting her torso away from the blade, and felt it catch the fabric of her blazer and the skin beneath—a hot, thin line of pain along her right side, superficial, the kind of wound that didn’t register as serious until later because the body had more important things to process.
The knife passed through the space where her abdomen had been and Palmer’s momentum carried him forward, off-balance for a fraction of a second.
A fraction was enough.
Isla brought the butt of her Glock up and drove it into Palmer’s face with everything she had.
The impact was precise and brutal—the flat base of the grip connecting with the bridge of his nose in a strike that sent a sound through the hallway like a branch snapping.
Palmer’s glasses shattered. His head snapped back.
Blood sprayed from his nose in a dark, immediate flood, and he staggered backward into the wall with the disoriented gracelessness of a man whose central nervous system had just received an urgent and contradictory set of instructions.
He didn’t drop the knife.
That was the detail that would stay with Isla afterward—the stubbornness of his grip, the way his fingers tightened around the brass knuckle guard even as blood sheeted down his face and his eyes lost focus.
He was hurt. He was reeling. But the knife stayed in his hand and his body was already trying to straighten, to reassemble itself for another attempt, because Raymond Palmer was a man who’d killed three people with historical weapons and hadn’t flinched, and a broken nose wasn’t going to stop what a decade’s worth of conviction had set in motion.
"Drop the weapon!" Isla had her gun on him, center mass, eight feet of hallway between them. Her side burned where the blade had caught her and she could feel the warm trickle of blood soaking into her shirt beneath the blazer. Palmer blinked through the blood on his face and looked at her—looked through her, almost, with an expression that wasn’t rage or fear or desperation but something closer to incomprehension, as though the interruption of his work was an error in a narrative he’d been writing and couldn’t reconcile.
He shifted his weight. The knife came up an inch.
Vaughn hit the top of the stairs like a force of nature.
The detective vaulted the last two steps and came down the hallway at a dead sprint, her weapon holstered and her hands free because she’d read the geometry of the situation in the half-second it took to clear the stairwell—Isla with a gun on the suspect, the suspect still armed, the hallway too narrow and the angles too tight for two firearms. Vaughn closed the distance before Palmer could turn, seized his knife arm at the wrist with both hands, and wrenched it sideways with the savage, practiced efficiency of a cop who’d spent fifteen years putting people on the ground.
