Three days after the first Thursday meeting, Joshua went back to the library.
He had been in it every evening since - standing at the shelves, pulling books, replacing them, circling something he hadn't yet named. The library was organized, he had understood the first night home, but not in any system he had been trained to recognize. Not alphabetically, not by subject, not by language or period of publication. He had assumed, initially, that his grandfather had simply shelved things where they fit.
He stood at the near wall and looked at the spines again. He had a thought.
The books were where he had left them. Floor-to-ceiling on three walls, the fourth wall being windows, the shelves so densely packed that some of the shorter volumes were doubled up behind taller ones. He had been through them once already, quickly, looking for the organizing principle and not finding it. The system his grandfather had used was not alphabetical, not by subject, not by language. He had assumed, the first time through, that Teodor had simply shelved things where they fit.
He stood at the near wall and looked at the spines. He had a thought.
He pulled a book at random - a 1962 Polish monograph on the Second Crusade, which he could read only partially - and looked at the dates on the spine, then at the dates of the books on either side of it. The books on either side were an 1891 French history of the Cathar suppression and a 2003 English translation of a 13th-century Arabic chronicle. Not the same subject, not the same language, not the same century of publication.
He went to the other end of the shelf. He pulled three books and looked at their dates of publication. Then he put them back and looked at the dates of the events they described.
He stood very still for a moment.
The books were organized by the date of the event, not the date of publication. The 1891 French history of the Cathar suppression was shelved under 1208, when the suppression began. The 2003 translation was shelved under 1236, the date of the Arabic chronicle's composition. The Polish monograph on the Second Crusade was shelved under 1147.
He walked the length of the room. The shelves started, in the far left corner, around 800 AD - a hand-copied manuscript in a protective sleeve that he had been afraid to touch - and ran forward through time to the near-right corner, where the most recent publication date he could find was 2019.
His grandfather had been building a timeline.
Not a filing system. A timeline. Teodor Maren had spent - how long? Decades, certainly, given the scope and the density - assembling a library organized not by how scholars had categorized history but by when things had actually happened. The whole wall was a continuous chronology of something, though Joshua couldn't yet see the shape of the something. He needed to walk it more carefully, section by section, to see what Teodor had chosen to include and what he had left out.
The gaps would be as informative as the books.
He pulled a notepad from the desk and started at the left wall.
He worked for two hours. He was not systematic - he pulled books at intervals, noted dates, built a rough map of the timeline's shape. What he found was not a general history of everything. The collection was highly selective. Whole periods were thinly covered; others were dense with material from multiple languages and perspectives. The density maps told him something.
Dense: the early Church councils, particularly Nicaea and Constantinople. Dense: the Carolingian period and the development of the Holy Roman Empire. Dense: 1095 to 1312, essentially the full arc of the Crusades with particular weight on the Templars. Dense: 1309 to 1417, the Avignon papacy and the Great Schism. Dense: 1789 to 1815, the French Revolution and its aftermath. Dense: 1917 to 1945, a period for which there were more books than anywhere else in the library except one.
The exception was 1307. The year of the Templar suppression. There were fourteen books covering events of that year alone, in five languages, including what appeared to be a hand-transcribed document that was not a published book at all.
Joshua looked at it for a long time without touching it.
He knew what it probably was. He had a reasonable hypothesis, given everything. He was going to ask Ambrose about it Thursday.
He put the notepad on the desk, turned off the study light, and stood in the doorway for a moment. His eyes had adjusted to the dark and he could see the shapes of the shelves, the irregular geometry of the spines. Seven hundred years of careful attention, organized by a man who had known something about what it meant.
He went to bed.
He woke at four in the morning, which happened sometimes, and lay in the dark of his grandfather's bedroom thinking about the compass.
It was on the nightstand, which was where he put it when he slept because it seemed wrong to leave it in his coat pocket overnight, though he couldn't have explained why it seemed wrong. He could see its outline in the dark.
He had been checking it, he realized, more than made sense. Not anxiously - he wasn't anxious about it. More the way you find yourself touching a specific object in your pocket, not for any reason, just because it is there and you know it. He was a man who didn't usually carry things. He traveled light by habit, resented unnecessary weight, had never worn a watch because he didn't want something on his wrist. The compass had been in his pocket, or on his nightstand, or in his hand, for eleven days.
He got up and took it to the window. Outside, the street was empty and the sky was beginning to show the first suggestion of not-quite-dark that precedes dawn by an hour and a half. He held the compass level and watched the needle.
It settled north without drama, the way it always did. Held. Waited.
For when you are lost. And you will be lost. Everyone is, at first.
He had been thinking about the note wrong, he realized. He had been reading lost as disorientation - not knowing where you are, not knowing which way to go. But a compass doesn't fix disorientation. If you don't know where you are, knowing which way is north doesn't tell you much. A compass is useful when you know where you are and you need to find a direction. It is the instrument not of the lost man but of the man who is about to move.
He stood at the window for a while longer. The street stayed empty. The sky continued its slow undarkening.
He put the compass on the nightstand and went back to sleep.
