Chapter 12: The Map
She found the error on a Thursday.
She had not been looking for it. She had been in the great hall because it was cold in the longhouse and the great hall had a better hearth, and she had been sitting at the far end of the table with a piece of parchment she had borrowed from Gunnar, which was intended for a list of the settlement’s medicinal herbs that she had been compiling out of the healer’s habit of documentation, when she had looked up and seen the map.
It was on the wall behind the Jarl’s seat — a large piece of hide stretched over a frame, covered in ink lines that were the Norse understanding of the western sea. She had been looking at it for five minutes as a general feature of the room before she looked at it properly, and then she stood up and walked to it.
The map was good. Better than she had expected — detailed in the Norse territory, precise about the fjord system, with the trading post at Bergen marked with a small square and the Orkney islands rendered with considerable accuracy. It degraded, as maps did, toward the edges of what the mapmaker had known directly. The Irish coast was present but wrong: the western headlands were placed too far south and the bay where her father’s hall sat was not a bay on this map but a straight shoreline.
She was staring at it when he came in.
She did not turn around. She heard his step — right foot heavier, always — and she heard him come to stand beside her at the map and she said, without preamble: “Your western coast is wrong.”
“I know,” he said. “The man who made it never went further than the Orkneys.”
“How are you navigating the Irish coast with an inaccurate map?”
“The men who have sailed it carry it here.” He touched his head briefly. “They don’t write it down.”
She looked at the map. She thought about the bay where her father’s hall sat, the specific inlet that made it defensible from the sea — the reason it had been her family’s seat for four generations. She thought about what it meant to give a Norse Jarl accurate coordinates for her father’s bay.
She thought about what it meant not to.
“The bay where my father’s hall is,” she said, “is here.” She pointed to the wrong spot on the map. Then she moved her finger south. “Here is where it actually is. The headland you have marked at the north is forty miles further north than indicated. The whole western coast is shifted.”
He was quiet.
She turned to look at him. “You can have Gunnar make corrections.”
He looked at the map for a moment. Then he went to the table — not his usual end, her end — and he picked up her parchment, which had the herb list and some idle sketching at the margins, and he found the charcoal she had been using and he came back to the map and began marking corrections.
He did it without commentary. He moved her finger’s point to the right location, made a small mark, noted the headland correction. He asked her two questions — the width of the inlet mouth, the rough position of the rocky shelf on the north side of the bay, the one that shipping had to know about — and she answered them, and he marked them.
Then he stood back from the map.
He had just made his own navigation more accurate for reaching her father’s bay.
She had just given it to him.
She stood very still with this.
He looked at her. “You’re wondering if you should have done that.”
“Yes.”
“Will you tell me what conclusion you reach?”
She looked at the corrections on the map. At the small charcoal mark where her father’s hall now sat, accurately, on a Norse map.
“My father’s bay is defensible,” she said. “The inlet mouth is narrow and there’s the rocky shelf to the north. A ship that doesn’t know about the shelf runs aground before it reaches firing range.” She paused. “Any ship entering that bay that doesn’t know the inlet is not a friendly ship. You will know the inlet because I told you, which means you will enter the bay as a guest rather than a raider. My father will see the difference.”
He looked at her.
“Or,” she said, “you use the knowledge to take the bay, in which case you have made an enemy of every allied clan on the western coast, lost the silver routes, and guaranteed that the Norse position on the Irish sea is contested for the next generation. Which is worse than never having had the map at all.” She met his eyes. “I know which calculation you make. That’s why I told you.”
He was quiet for a long moment.
“You trust my calculations,” he said. Not a challenge, not a compliment — an observation, turned over like a coin.
“I trust your intelligence,” she said. “I don’t trust your intentions. They’re not the same thing.”
He looked at her with an expression she had not seen on him before and did not have a name for — something that was not the professional assessment, not the careful management of distance, but something underneath both of those that she had only glimpsed in fragments. In the laugh. In the moment on the dock when he had stood next to her and looked at Ireland with her.
“What would change the second thing?” he said.
She held his gaze. “I don’t know yet.”
He nodded. Slowly, the way he did things — as though he had all the time available and was choosing to use it properly. “That’s a fair answer.”
He put the charcoal down. He went back to his seat at the other end of the table.
She went back to her herb list. The map was on the wall between them, corrected, accurate in the small critical ways that mattered.
She kept her face toward the parchment and her attention on the herbs and she thought about the fact that he had corrected the map in front of her — had not gone away and made the corrections in private, had not sent Gunnar, had done it here with her watching.
She thought about what he was doing with that.
She thought about what she was doing.
She was giving a Norse Jarl the navigation to her father’s bay, and she was calling it strategy, and it was strategy. It was also something else. It was also the act of someone who had decided, without quite deciding, that this man’s intelligence could be trusted in the specific way you trusted someone’s intelligence when you had been thinking alongside it long enough to know its shape.
She did not want to examine how long that had taken.
She thought: the map is corrected. The bay is readable. What he does with it is what it is.
She thought: you have been watching him for weeks and you know what he does with things.
She thought: that is not the same as knowing what he does with you.
Outside the great hall the settlement went on in the cold, and the fjord held its grey patience, and the winter ahead of her grew incrementally closer, and Aoife Ó’Briain sat at a Norse table making a list of herbs and told herself she was still, in all the ways that mattered, in possession of herself.
She believed it less than she had a month ago.
She believed it less with every passing day.
