The river ran its whole length at last — that was the thing he had done this week, at eighty, from a ladder, with Ellen bringing tea and Kessler holding the ladder's foot and pretending he was only there to inspect the drop cloths. Everywhere the old paint had dulled and grayed, the blue was back, deep and lit from beneath, one water again from the spring to the boat. It ran in the color he had made for her in 1978, in the little back room of Store No. 1, because she had come in with a sketchbook under her arm and a complaint — not about him, about blue. The blue of night water, she said, did not exist in any can. Every blue in the store was a daytime blue; but the blue of a river after dark, almost black and entirely alive, the blue with the light underneath it, was nowhere on the shelf, and she intended to paint a whole mural out of exactly that blue.
It had taken him nine nights. The failures stood in a row of labeled jars she refused to let him throw away, and on the ninth night she took the card off the bench, held it against the window where the snow was falling through the streetlight, and said, quietly, "That's it. That's the river at night" — to the color, not to him, which he understood at once was the greater compliment. Formula Card No. 001. Marlene Blue. He named it that evening, the only name it could have had, and she refused every other name for it for forty-one years.
He had reached the end of the wall. And there — low, where the river met the baseboard at the room's far corner, at exactly the height of a child's shoulder — was the square of wall Marlene had left unfinished in 1985.
It was not large. A child could cover it with two hands. In it the underdrawing still showed, her pencil as light and sure as handwriting on the inside of a wrist: the river's last curve coming down, a spill of small stones, the suggestion of reeds. And in the underdrawing's sky the faint ghost of stars, uncolored, waiting in pencil for forty years. She had painted up to its edge and stopped, and when the branch librarian of 1985 — a formidable woman named Mrs. Agnew, who had terrified two generations of overdue patrons — asked whether the mural was finished, Marlene had said: "It's finished except the part that's theirs."
"Theirs, Mrs. Hartley?"
"The children's. When one of them is ready, she'll know what goes there. Don't let anybody paint it in a hurry, and don't let anybody paint it to match. It's not a gap. It's a seat I've saved."
Mrs. Agnew had written that down in the branch's records, and guarded the corner like a border for eleven years, through two renovations and one flood.
All week, working the wall above it, Amos had felt the corner's presence below him like a held note. People had asked — Kessler on Wednesday, carefully; Ellen on Thursday, more carefully still — whether he meant to finish that too, while he was up. And Amos had said no, and then the rest of it: that the corner was the one part of the mural he had never had any right to, and a man who finishes another person's saved seat has not understood the first thing about the person who saved it.
"Forty years it's waited," he said aloud. "Through the years when the company was doubling and I was — elsewhere. It just waited. That's the thing about a seat you've saved. It doesn't expire."
"No," Ellen said. "It doesn't." She touched his sleeve, briefly. "Tea, before the hordes. And then I need you to stop being a ghost in your own finish and be a guest of honor. The hordes are bringing juice boxes."
The hordes arrived at nine on the dot — two dozen children in a rush that checked itself at the threshold, parents and grandparents behind — and then the rush stopped, and the room went quiet in the particular way a room full of children goes quiet perhaps six times in a decade, because the river was running again.
Amos watched it from the chair Ellen had placed for him by the boat — watched a boy of five walk straight up to the heron and hold his own leg up, high-stepping, before his mother could stop him, and three girls sit down before the otter family without consultation, the way you sit down in front of weather.
The speeches were kept short, because Ellen had given every speaker a limit. The mayor's aide said the river was back. The library director said the mural belonged to everyone who walked in, which Amos thought was the truest sentence spoken all morning. Ellen said the least and the most: that a room's job was to be ready before the children arrive and to stay ready after they leave, and she thanked Marlene Hartley, "who painted us a river and left us a seat in it."
