The blizzard came over the Slag-Roots an hour after the hounds lost him.
Valerius pitched the oil cloth against the lee of a petrified trunk at the bog's edge and sat under it with his knees drawn up and the three chains looped twice around his left gauntlet. The hounds lay against his legs in a heap of iron and steam. They had stopped whining an hour ago. Hounds bred for six generations to hold a scent did not take losing one well, and they had lost this one cleanly, at a drainage ditch a mile south, where the trail went into the slurry and did not come out.
He did not blame them. He had stood at the edge of that ditch with a lantern and read it himself. The outriders had ridden straight across it. Four horses, crystal-bearers on the flanks, the churn of their passage laid over everything like a hand wiping a slate. If the man had been in that ditch when the column crossed, he had either drowned or been very, very still.
Valerius did not think he had drowned.
The outriders' report lay open on his knee, weighted against the wind with the flat of his baton. The handwriting was a sergeant's, cramped and certain. Sweep complete. No contact. Fugitive presumed lost in the bog. Presumed. The word sat on the page like a man who has decided to stop looking for his keys.
He read it twice more by the shuttered lantern and then folded it away, because it had nothing further to tell him.
The man had something to tell him. The man had been telling him things since the western road.
Valerius went back over it in order, the way the Snow Fox manuals taught: not what the quarry did, but what the quarry chose.
The ambush in the rut had been chosen. Hours buried in freezing slurry for one throw of one flask, and the flask had been aimed at the bearskin, not the man, because the bearskin would burn longer. The hamstring had been chosen. Not the throat. A man who wanted Drago dead would have gone for the throat. A man who wanted Drago unable to follow went for the leg and let the cold do the rest.
And the sword.
That was the one he kept coming back to. A short broadsword of good Boyar steel, Anatoly's house mark under the guard, lying a yard from the body where the fight had dropped it. A year's wages in the mud. The man had looted the coat. He had taken the silver, and whatever else had been sewn into that lining. And he had left the one thing in that rut a common thief would have reached for first.
Because a marked blade could not be hidden under a coat. Because a vagrant carrying a noble's sword would hang in the first town he walked into. Because he had looked at the most valuable object within reach and done the arithmetic on what it would cost him, standing there in the cold with one working arm, and walked away from it.
Valerius had read a great many tracks in twelve years. He had never read one that told him so clearly what kind of man had left it.
There was a line in the third Snow Fox manual, in the chapter on long pursuits, that the instructors made every acolyte copy out by hand until he could recite it without the page.
The quarry tells you who he is by what he refuses to leave behind, and by what he refuses to take.
Valerius had been nineteen when he copied it. He had been twenty-three when he stood before the examining chapter for his white tabard, and the examiner, a Purifier with a burn scar down one side of his face, had asked him a single question about a heretic's trail in the Pale Crags. Valerius had given the right answer. He had given it in full, with every inference in order.
The examiner had listened to all of it. Then he had said, not unkindly, You read the ground very well, acolyte. You read it like a man who would rather be reading than finding. And he had sent him back to the kennels for another year.
That had been nine years ago. Valerius had found a great many men since. He had never been called back before the chapter.
The wind changed pitch over the trunk. The lead hound lifted its head, scented nothing, and put it down again on his boot.
He let himself consider, for the length of one breath, the possibility that the sergeant was right. That the man had gone into the slurry and the bog had kept him, and somewhere under the snow tonight there was a body with an open wound and a cracked sword and a pouch of grave-robbed silver, and that would be the end of it. A report. A line in a ledger. Presumed.
Then he let the possibility go, because it did not fit. He could be wrong. He had been wrong before, in front of men who made sure he remembered it. But not, he thought, about this.
A man who would lie in a rut for hours to make one throw count did not drown in a ditch. A man who would walk away from a year's wages because he had done the arithmetic did not lose his head in a bog. He was out there somewhere in the Slag-Roots, in the dark, in this weather, with a fever coming on and the iron-weed in his arm going quiet as it dried, and he was doing the arithmetic again.
Valerius looked out past the oilcloth's edge at the blizzard. The snow was coming in sideways now, filling every track in the bog, smoothing every ditch.
At first light he would sweep the root hollows along the bog's southern edge. Every one of them. A man with a fever and an open wound and no fire would not stay in the open tonight. He would find the deepest hole he could and get into it, and the snow would cover the mouth behind him, and he would wait.
Valerius knew that because it was what he would have done.
He pulled the chains a little tighter around his gauntlet, settled his back against the trunk, and kept watch on the dark until it went grey.
