They followed for a hundred yards.Then two hundred.The prints maintained their urgency—long strides, deep penetration, consistent and strong.Isla cataloged each impression: large boot, size eleven or twelve.Deep heel strikes indicate a runner's posture.The stride length was significant.Not a small man.Not an old man.Someone tall, strong, and conditioned enough to sprint through knee-deep powder without faltering.
At approximately five hundred yards from the clearing, the trail ended.
Isla's flashlight followed the prints to their final impression—a deep bootprint, slightly turned, as if the runner had planted his foot.Beyond it, nothing.Pristine snow stretches between the dark columns of surrounding trees without a single mark.
“That’s not possible.”
Marshall was sweeping the area in systematic arcs.The deputies fanned out.Every light found the same thing: undisturbed snow.No prints continuing.No prints branching.No prints doubling back.
Isla crouched beside the last bootprint.Deep and clean—full weight of a man in motion, tread pattern sharp.Real.Physical.Mass did not simply stop existing.
She stood and raised her flashlight above the snow line.Trees.Dense spruce, branches heavy and low—
“Rivers.”
Marshall’s voice was quiet.He’d moved right of the trail’s terminus, his flashlight angled upward.Isla followed the beam.
A downed limb.Six inches in diameter, lying beneath a spruce whose trunk rose straight and thick.The limb had broken at about ten feet up—the fracture point visible, wood fresh and pale.But the break wasn’t weather damage.The limb had been pulled downward, and the bark showed compression marks of something gripping it.Hands.
“He went up,” Marshall said.
Isla rebuilt the sequence: the killer running, the trail ending at this tree, the leap upward, hands finding the branch, body weight pulling as he hauled himself up.The limb had held long enough, then broken after he’d climbed past.
She raised her light higher.The spruce's branches were dense and regularly spaced—natural ladder rungs.Adjacent to this tree, canopy overlapping, stood another spruce.And besides that, another.The forest here was a connected architecture of interlocking branches.Someone moving through the canopy—leaping tree to tree—could travel horizontally without touching the ground.
“He climbed the tree,” Isla said.“Ran five hundred yards through deep snow, climbed it, and went tree to tree through the canopy until he could drop down somewhere his tracks wouldn’t connect to this trail.”
Marshall was still looking up.“That’s—”
“Impossible?”She looked at the downed limb, the canopy that had swallowed a killer as completely as if the forest itself were complicit.“Nothing about this person has been possible.He carves sixty-foot designs without leaving prints outside the lines.He carries bodies hundreds of yards through deep powder.And now he goes up a tree at full sprint in the dark.”
“Someone in exceptional physical condition,” Marshall said.“This isn’t just strong.This is someone who climbs, who moves through wilderness the way an athlete moves.Someone who trains for this.”
He was right.The profile they’d been building had just expanded into something that felt closer to extraordinary.
But the killer had left something behind for the first time—the unfinished pattern, the panicked footprints, the broken limb.For the first time, Shaw's helicopter had forced improvisation, and improvisation left evidence that patience did not.
Her phone rang.The caller ID read Channing.
"Channing, we're at the scene.Third victim, male, young—possibly a snowmobiler.The pattern is incomplete.Shaw interrupted the killer, and we have a foot trail, but it terminates in the canopy.He's gone."
“Isla.”Kate’s voice stopped her.It wasn’t the tone of a commander receiving a field report.It was something Isla had never heard from Kate Channing—not during James’s hospitalization, not during the Brune manhunt, not during any crisis that had tested professionalism against raw pressure.
Kate sounded shaken.
“I need you to come to the office.You and Marshall.As soon as you can hand off the scene.”
“Kate, I have an active crime scene—”
“Immediately, Isla.”A pause.Through the phone, Isla heard something she’d never heard in Kate Channing’s breathing: the ragged quality of a woman working to control her voice.“Something has come in.I can’t discuss it on the phone.But you need to be here.”
Isla looked at Marshall.He was reading the change in her expression the way he’d learned to read the shifts in a case—not the way James would have, but with enough sensitivity to understand that whatever was coming through that phone had altered the landscape of the night.
“We’ll be there.”
CHAPTER TWENTY-TWO
The field office at ten o'clock at night had the hollow, humming quality of a building that was winding down.Fluorescent lights buzzed in the bullpen.The elevator groaned once, settling, and then was silent.The coffeemaker in the breakroom had been left on, and the smell of burnt grounds drifted through the hallway like a low-grade accusation.
