She stayed away from the shop for three days, and the three days cost her more than the going had.

She had thought the danger was in crossing the street. She understood now that the danger was already in her, installed, the way the small grey number was installed on her side of the bed — that a man had said somebody's taught you to take up less room than you take and she could not un-know it, could not move through her own kitchen anymore without watching herself turn the mug handle to face the shelf, set her water glass down silently, leave no proof she'd been in the room. He had not added a chain to her. He had shown her the chain that was already on. And the only place she wanted to be was the one room in Riverbend where a person had looked at the chain and not pretended it was jewelry.

David, meanwhile, tightened.

He did it the way he did everything, gently, in the grammar of care. On Thursday he mentioned, setting down his fork, that he'd noticed the living-room curtain open before ten one morning that week — the light, sweetheart, the cushions — and would she mind keeping it closed until he left, he'd feel better. She had not opened the curtain before ten. She had lifted the corner of it, once, at six, to look at a dark shop. She did not say so. She heard the sentence for what it was: I know you go to that window.

On Friday it was the calendar. He sat beside her on the couch with his phone and showed her, warmly, a shared one he'd set up — so we're not crossing wires, so I always know where to find you if there's an emergency at the hospital and I have to reach you — her walk blocked out in pale green, nine to ten, the market, the loop. The bench on Thursdays was not on it. He had not put the bench on it. He had put everything else on it. She looked at the pale green block that was her one free hour rendered as an appointment with a known route and a known duration, and she said that's thoughtful, and felt the apartment close another quarter-inch around her like a hand that had not yet made a fist.

She lasted until Monday. Three days of the loop drawn in pale green, west to the cottonwoods and back, while the green awning sat unentered across the street and the field guide she had not taken waited on a shelf with the tea. Three days of David coming home to read her face for the dip, and finding it, because there was a dip — there was a whole woman missing from her own kitchen — and prescribing rest for it, and a quiet weekend, and no more fire hoses. Three days in which she understood that staying away from the shop did not keep her safe; it only kept her his.

On Monday David had surgery from eight and a thing after that ran late, and the pale green block on the shared calendar said walk, 9–10, and Sarah walked the loop exactly as drawn, west to the cottonwood corner and back, in case the calendar could see her — and then, at the bottom of the loop, with eleven minutes left in the pale green hour, she crossed the thirty-two feet.

The bell sounded. Jude looked up. He did not say you came back this time. He looked at her for a moment with something careful and unhurried in his face, and then he simply went on with what he was doing, which was kind — it gave her a wall to stand against that wasn't his attention.

She made herself useful to keep from leaving. She drifted along the front table where the new arrivals lay, and her hands did what her hands did, squaring a stack, turning a face-out book a degree straighter, and he let her, and the silence between them was easier than it had been, a worked-in silence, the kind two people who both knew how to be quiet could share without it costing either of them.

"This one's mis-shelved," she said, lifting a slim hardback. "It's a translation. You've got it under fiction-A but the translator's name is the one people will look for. It always is, with this press." She heard herself — the editor, the voice that knew things, out loud, in a sentence no one had written for her.

"Show me where it goes."

She carried it back into the stacks and he came with her, and they stood close in the narrow aisle, closer than the aisle strictly required, and she found the shelf and slid the book into its place, and her hand stayed on the spine a second longer than the shelving needed, and his hand came up to the same shelf — to steady a leaning row, he would have said, if anyone had asked — and for a moment their two hands were on the same eight inches of wood with the width of the slim book between them, not touching, near enough that she could feel the warmth coming off his skin the way she had felt it across the counter over the bookmark.

Neither of them moved the last half-inch.

The aisle had gone very quiet, the dust hanging gold in the one shaft of light from the front window, the smell of old paper and the green ghost of tea, and she could hear him breathing, slow, even, deliberately even, the breath of a man holding himself extremely still. She knew that stillness. She had lived inside a man's stillness for fourteen months. But David's stillness was a held threat, a thing about to move toward her and take; this stillness was a held restraint, a thing holding itself back from her on purpose, leaving the whole decision in her hand the way he'd left the bookmark and the tea and the open shop. The difference between the two stillnesses was the difference between a cage and a door, and her body knew it before her mind would say it.

That was the thing. He did not close it. He never closed any distance; he only ever set a door ajar and stepped back from it. She understood that if their hands touched in this aisle it would be because she had moved, and the understanding ran through her like current, because she wanted to move — wanted it with a sudden plain physical force that had nothing to do with safety, that was not gratitude or relief or the comfort of being seen, but want, low and bright, the want of a woman who had been told for fourteen months what she felt and was discovering, in a bookshop aisle, that her own body had kept its own counsel after all. She watched her own hand on the spine of the book, an inch from his, and thought with a kind of wonder that it was her hand, that the wanting in it was hers, unedited, unassigned, the first feeling in over a year that had arrived without anyone telling her its name.

Her tongue found the chipped tooth — the small scallop of enamel from a bicycle and a hardware store in Burlington when she was twelve, her one piece of proof that her body had once been free to fall — and she stood at the edge of the half-inch and did not cross it, and he did not cross it, and the not-crossing was the most charged thing that had happened to her in a year.

"You should keep this," he said quietly. He had taken something from his pocket — not the slim translation, something else, a worn green clothbound book the size of her palm. A field guide. Trees of the Northern Forest. "You were trying to remember a stand of trees. The other day. You didn't finish saying which kind." He set it on the shelf beside her hand, near it, not in it. "In case you ever want to be sure of something without asking anyone whether you're right."

She did not take it. She looked at it on the shelf and her eyes stung for the second time in a week and she said, "I can't bring that home." And he heard everything in the sentence, the whole architecture of it, and he nodded once and left the book where it was and said, "Then it lives here. With the tea. It's always on too," and she laughed, wet, once, and it was the second laugh in a week, and she thought, I am in terrible danger and I have never felt this awake.

She thought of the calendar, the pale green block, the watching she had agreed to call thoughtful. She thought of the curtain she'd been asked to keep drawn. She thought, standing in the gold dust with her hand an inch from his, that she was a married woman, and that the word married had once meant a man who hung the moon and now meant a shared calendar and a hygrometer on her side of the bed, and that the distance between those two meanings was the real cliff, the one she had been standing at the edge of for fourteen months without letting herself look down. She looked down now. It was very far.

"I have to go," she said, and this time it was not panic. It was arithmetic. The hour was spent.

"I know," he said. He did not ask her to stay. He never asked her for anything. That, too, was a door.

The pale green hour was gone. She went home at ten-forty, late, and she did not have a lie ready, and she climbed the brownstone steps composing one, and at the top of the steps she stopped.

The apartment was on the second floor, west side. Their windows faced Main and the shop. And from the street, looking up, she could see the living-room curtain — the heavy oatmeal linen David had asked her to keep drawn until he left.

It was drawn. But not square. The corner of it, the far corner, the one nearest the window's edge that gave the cleanest sightline across the street to the green awning and the plate glass of Halloran's, had been folded back and hooked — neatly, deliberately, on the little curtain tieback she had never once used — so that a narrow vertical slot of glass stood open to the street. A watching slot. Angled not at the sky, not at the cottonwoods, not at the corner where she walked her drawn-in loop.

Angled at the shop.

He had left for surgery at eight and a thing after that had run late. She had walked the loop the calendar drew. She had crossed the street with eleven minutes left and stood close to a man in a narrow aisle, and the whole time, the curtain she had been told to keep shut had been hooked open on its tieback to watch the one place she had gone.

She stood on the steps with the key in her hand and the cold coming up off the slate, and she understood, finally and completely, that David had not been asking about the bookshop because Emma had mentioned it.

David had been watching the bookshop himself.
