CHAPTER 4 #2
Her own room's desk was adequate for most work, but the Layer 2 cipher material had spread beyond adequate — she had eleven pages of verbatim source transcription she had made at the Warren carrel that first week (the only legitimate way to take Liber Noctis home), three frequency charts, a running concordance, and a growing collection of cross-reference notes that needed to be laid out simultaneously.
Spatial arrangement was part of her analytical method; she needed to see the whole structure at once, and that required a surface she didn't have.
The dining room had a surface twelve feet long. She had been using it in the afternoons when it was empty.
It was not empty.
Lysander was at the standing desk at the far end of the room, back to her, when she came in.
He had his coat on still, which she took to mean he had arrived recently.
The standing desk had his laptop open and what looked like a stack of photocopied documents weighted at the corners with a coffee mug and a small stone paperweight she had registered in passing on previous afternoons in the dining room — dark gray, oval, the kind of thing bought at an airport or found on a beach and kept for no stated reason.
He did not turn around when she came in.
She set her bag on the chair nearest the middle of the long table, far enough from his end to constitute a reasonable partition, and began laying out her materials.
Source transcription pages in order. Frequency chart pinned at the top left corner with her thumb while she unrolled it against the table's surface.
The notebook open to her running concordance. Two pencils and her pen.
"Afternoon," she said. Not a question, not an opening. Just the acknowledgment that there was another person in the room.
"Afternoon," he said, without turning.
She worked.
The room had a quality in the afternoon that was its own — the light from the tall south-facing window went amber by two o'clock and turned everything slightly warm, slightly slowed.
The standing desk clock she could hear from her position ticked at a pace almost too slow, like a metronome set for patience.
The room held the smell of old paper and the faint mineral note of the stone paperweight; from the kitchen, when he was gone, drifted the smell of fresh-ground coffee.
Lysander turned pages at intervals. She heard the soft mechanical sound of him typing and then the longer silences when he was reading.
He made no other sound except once, quietly and without emphasis, a single note under his breath — not a word, just a toneme, the sound a person makes when something they're reading confirms something they already suspected.
She identified two additional trigraph patterns in the concordance and wrote them down.
The cipher's structure was becoming clearer at a pace she was beginning to distrust — the most elegant solutions were usually the wrong ones; the ones that clicked too fast were almost always traps.
She wrote: check base alphabet assumption — what if the shift is not constant? and underlined it.
The room ticked. The light went more amber.
Forty-five minutes passed in this configuration, and the notable thing about it — the thing she was noting without looking directly at it, the way she noted most things — was that it required no maintenance.
There was no performance of working in front of another person, no subtle adjustment for an audience, no corner of her attention allocated to managing the social fact of his presence.
He was there. She was there. Both of them were elsewhere, in the problems they were inside. The room contained this without strain.
She had not experienced this category of company before, or not recently enough to have comparison data readily accessible.
He said, "I'm making coffee," and she heard him move away from the standing desk toward the kitchen, his footsteps quiet on the floorboards.
◆
He had left the Bacon on the table nearest the standing desk.
She saw it when she stood to stretch — four pages of her concordance needed to be shifted to accommodate a new cross-reference column, and she walked the length of the table to retrieve the end pages, and the Novum Organum was there, face-up, open.
She didn't mean to read it.
It was in her peripheral path, open to somewhere in Book Two, and she happened to have peripheral vision, and some things were simply too clearly written to not receive.
Three lines of blue ink in the margin: cramped, excited handwriting, the kind of marginalia that was in a hurry because the thought was arriving faster than the pen could move.
But this is exactly what Descartes got wrong — the induction isn't the problem, the premise selection is — you need a filter before the method, not after.
The letters were slightly irregular, uneven pressure, a person writing at speed because they were twenty-two and had just understood something and it was urgent.
She could read the age in the handwriting. She could read the specific bright quality of a mind encountering something that delighted it.
