Chapter 67: The Cartulary of Frozen Letters

The snow had stopped by the time they reached the fork in the road, but the cold had settled into Aldric’s bones like a tenant who refused to pay rent. He reined in his horse at the crossroads, staring at the two paths that diverged before him: one wound west toward the Rhine and the familiar comforts of Aachen, the other plunged south through the frozen passes toward Rome.

Gerold drew up beside him, breath pluming in the still air. “The letter,” the Saxon said, as if reminding a child of a chore. “You said we had one to intercept.”

“I said a great many things,” Aldric replied, “most of them foolish. But yes. The letter.”

He reached into his saddlebag and withdrew the parchment Hildegard had given him at the shrine—a copy of the message she claimed was already speeding toward Pope Leo, carried by a veiled woman with her own agenda. The script was elegant, precise, the kind of hand that had been trained in a scriptorium and never once hurried. Aldric had read it so many times over the past days that he could recite it from memory: a careful enumeration of Charlemagne’s sins, his ambitions, his willingness to reshape Christendom in his own image. It was not a letter that would stop the coronation. It was a letter that would ignite it.

“The woman who carries it,” Rotrude said, appearing beside him as if conjured from the snow, “do you know her name?”

Aldric folded the parchment and tucked it away. “Hildegard did not see fit to tell me. She said only that she was veiled and rode with the pope’s blessing.”

“Convenient,” Rotrude observed. “My father has spies in every court from the Elbe to the Tiber. If this woman exists, he will find her before she reaches Rome.”

“Unless she is already there,” Aldric said. “Hildegard’s arithmetic is rarely wrong. She would not have sent me chasing a ghost unless the ghost was real.”

Rotrude tilted her head, studying him with that unnerving intensity she had inherited from her father. “You still trust her. After everything.”

“I trust her arithmetic,” Aldric corrected. “Trusting Hildegard herself would be like trusting a river to flow uphill. But her numbers have never once failed me.”

“And what do her numbers say about this?” Rotrude gestured at the road ahead, the endless white expanse that swallowed all sound and sense of direction.

Aldric was quiet for a moment, letting the cold seep into his thoughts. “She said the letter would cut the knot or tighten it beyond all hope of escape. Those were her words. She did not tell me which outcome she preferred.”

“Then we are riding blind,” Gerold said flatly.

“We are riding south,” Aldric corrected. “That is not the same thing.”

He urged his horse forward, choosing the path that led through the frozen marshland toward the great monastery of Saint Gall, where Hildegard’s letter had supposedly been copied before being sent onward. If the veiled woman had passed this way, someone would remember. Someone always remembered a veiled woman traveling alone in winter.

The road was treacherous, slick with ice beneath a thin crust of snow, and they made slow progress. Aldric’s mind churned through the possibilities like a mill grinding grain that would never become bread. If the letter reached Pope Leo before Charlemagne arrived, it could poison the negotiations before they began. The Emperor would be forced to respond, to defend himself against accusations he had never anticipated, and the carefully constructed plan for the imperial coronation would crumble into chaos. That was the outcome Aldric had once desired—a coronation too costly to pursue, a freedom earned through the wreckage of imperial ambition.

But that was before he had seen the ashes of Regensburg. Before he had watched Charlemagne’s army march through the Saxon marches, leaving behind villages that would never rise again. Before he had understood that the Emperor’s fury, once unleashed, did not discriminate between enemies and obstacles.

The path of least resistance, Aldric thought bitterly. It has never once led me home.

They reached Saint Gall as the evening bells were ringing, the monastery rising from the snow like a fortress of stone and faith. The abbot received them with the wary hospitality of a man who had learned to expect trouble from travelers bearing royal letters. Aldric produced his credentials, and the abbot’s wariness deepened into something closer to fear.

“The Emperor’s envoy,” the abbot said, studying the seal. “We were not told to expect you.”

“I was not told to come,” Aldric replied. “But the road is full of surprises. I am seeking a woman—veiled, traveling alone, carrying a letter from the Abbess Hildegard of Metz. She should have passed this way within the past fortnight.”

The abbot’s face betrayed nothing, but his fingers tightened around the parchment. “We have seen no such woman.”

“Then you will not mind if I search your guest book,” Aldric said, allowing a note of steel to enter his voice. “The Emperor’s service requires thoroughness, as I am sure you understand.”

The abbot hesitated, and in that hesitation Aldric found his answer. The woman had been here. The letter had passed through. And whatever it contained had already moved one step closer to Rome.

Gerold stepped forward, his hand resting on the hilt of his sword, and the abbot’s resistance crumbled like snow in a warm hand.

“The woman stayed three nights,” the abbot admitted. “She was ill—the cold had taken her lungs. She left before dawn, taking the road south. She paid for a fresh horse and a guide to see her as far as Chur.”

“A guide,” Aldric repeated. “What sort of guide?”

“A local man. A hunter, I believe. He knew the passes.” The abbot’s eyes flickered with something that might have been shame. “She paid him well. Too well, perhaps. I did not ask questions. The Abbess Hildegard’s seal was on her letter, and I have learned not to question the abbess’s business.”

Aldric exchanged a glance with Rotrude. Hildegard’s reach, it seemed, extended even into the frozen recesses of Saint Gall. The woman had been given every advantage to reach Rome before them—a fresh horse, a guide who knew the passes, and a head start of nearly a fortnight.

“Then we ride for Chur,” Aldric said, though the words tasted like ash. “We have a letter to intercept.”

He turned to leave, but the abbot’s voice stopped him. “My lord. The woman—she left something behind. A message, she said, for anyone who came asking after her.”

Aldric froze. “What message?”

The abbot reached into his robe and withdrew a folded parchment, sealed with a blob of wax that bore no insignia. Aldric took it, broke the seal, and read the single line written in a hand he knew all too well.

*You are late, Aldric. Again.*

He crumpled the parchment in his fist, feeling the cold burn of Hildegard’s amusement through the paper. She had known he would follow. She had counted on it. And she had left this message to remind him that she was always, always one step ahead.

“We ride for Chur,” he repeated, and this time there was no hesitation in his voice. “And then we ride for Rome. I do not care how many veiled women or hidden letters stand in our way. That coronation will happen on my terms, or it will not happen at all.”

Gerold grunted. “You said you wanted to ruin it.”

“I said a great many things,” Aldric replied, swinging into the saddle. “Most of them foolish.”

He urged his horse forward into the gathering dark, the crumpled parchment still clutched in his fist, and behind him the monastery bells began to toll the hour of compline, as if the very stones were counting down the days to a reckoning he could no longer avoid.
