Chapter 15: The Arithmetic of Snow

The snow began before they reached the ford, a thin white veil that turned the world soft and silent. Aldric pulled his cloak tighter and watched the flakes settle on Gerold’s shoulders like a bishop’s vestments. The Saxon rode ahead, scanning the tree line with the patient vigilance of a man who expected an arrow from every shadow.

“We should have taken the river road,” Aldric muttered.

“You said the river road was longer.”

“Longer, yes. But warm.” He gestured at the grey sky. “This is the sort of cold that gets into a man’s bones and stays there.”

Gerold grunted. “You Franks complain about weather the way you complain about everything else.”

“We complain because we have standards.”

The horses splashed through the shallows, ice cracking beneath their hooves. On the far bank, the road to Regensburg cut through a dense stand of oak and beech, the branches heavy with snow that had not yet fallen. Aldric’s mind, as it always did when he rode, wandered to the arithmetic of the journey: so many leagues to Paderborn, so many days before Charlemagne’s patience ran thin, so many schemes left to fail before he could finally, blessedly, go home.

The arithmetic did not favor him.

“My lord,” Gerold said, reining in. “Riders.”

Aldric squinted through the falling snow. Three horsemen emerged from the trees, their cloaks dark with moisture, their horses steaming in the cold. They flew no banner, but their harness was Frankish—good leather, clean iron. A royal courier, then, or something worse.

“Hail,” Aldric called, keeping his voice even. “State your business.”

The lead rider pulled back his hood. His face was young, raw with windburn, and his eyes held the flat certainty of a man who had ridden through worse. “Lord Aldric of the Vosges?”

“That depends on who’s asking.”

“I am Brother Anselm, messenger to the court of the Emperor.” He reached into his saddlebag and produced a rolled parchment, sealed with the royal bull. “His Majesty commands your presence at Paderborn by the feast of Saint Andrew. He bids you make all haste.”

Aldric took the parchment but did not break the seal. “All haste,” he repeated. “Does His Majesty have any notion what the roads are like this time of year?”

“His Majesty has notions about many things, my lord.” The courier’s tone was carefully neutral. “He also instructed me to inform you that the Avars have renewed their raids along the Danube, and that your expertise in drainage may be required.”

Aldric stared at the man. “Drainage.”

“His words, my lord.”

“The Avars are raiding, and Charlemagne wants me to think about ditches.”

Brother Anselm’s mouth twitched, almost imperceptibly. “His Majesty said you would understand.”

Aldric understood, all too well. The Emperor was not summoning him for drainage. He was summoning him to remind him that his schemes, however clever, were visible—and that the price of freedom was always higher than the cost of service. The writ of immunity Hildegard had promised him felt like a distant memory, a warm fire in a cold landscape he could no longer find.

“Very well,” Aldric said. “Tell His Majesty I am on my way.”

The courier nodded and wheeled his horse. The three riders vanished into the trees as quickly as they had come, leaving Aldric alone with the snow and the silence and the weight of the parchment in his hand.

“Paderborn,” Gerold said. “That’s a long ride.”

“Yes.”

“Through the Saxon marches.”

“Yes.”

“The Saxons are not fond of Franks.”

“They are not fond of anyone,” Aldric said. “They are an equal-opportunity people.”

Gerold’s scarred face cracked into something resembling a smile. “You know, my lord, for a man who wants nothing more than to lie in a vineyard and drink wine, you spend a great deal of time riding toward danger.”

“That is the tragedy of my life,” Aldric said. “I have never once been given the choice.”

They rode on. The snow deepened, and the road narrowed, and the cold crept into Aldric’s bones exactly as he had predicted. By the time they reached a small monastic settlement at dusk, his hands were numb and his temper short. The abbot, a thin man with a nervous tic, offered them shelter in exchange for a blessing and a donation.

Aldric gave him both.

The monks’ refectory was warm, at least, and the bread was fresh. Aldric sat by the fire, the Imperial writ unread in his lap, and watched the flames consume the words he had not yet spoken. Hildegard’s plan—make the coronation too costly, force Charlemagne to release him—felt like a castle built on sand. The Emperor did not bargain. He took.

“You’re brooding,” Gerold said.

“I’m thinking.”

“Same thing, with you.”

Aldric did not answer. He was thinking about Rotrude, about the way she had looked at him in Aachen, as if she could see through his carefully constructed idleness to something she found amusing. He was thinking about Hildegard, and the arithmetic she had promised him, and whether it would be enough. He was thinking about the imperial crown, that glittering promise of a new Rome, and whether his name was already written in its gold.

And beneath all of it, that treacherous whisper again: *You could shape this. You could make it yours.*

He had crushed it a hundred times. It always came back.

“We leave at dawn,” Aldric said. “Paderborn, then the Danube. Whatever Charlemagne wants, I want it over with.”

Gerold nodded and settled against the wall, his hand resting on his sword. “And after?”

Aldric looked at the fire. “After, I will go home. I will sit in my vineyard. I will drink wine and read books and sleep until the sun burns out.”

“And if the Emperor won’t let you?”

Aldric’s smile was thin and tired. “Then I will have to find a way to make him.”

But even as he said it, he felt the weight of the road ahead, the cold and the snow and the long march toward a crown he did not want. And somewhere in the dark, as the fire crackled and the monks sang their evening prayers, he heard the faint, distant sound of hooves on frozen ground—and the certainty that his journey had only just begun.
