Chapter One

The train from Washington reached Baltimore a few minutes ahead of schedule, which Elias Mercer noticed only because so little in his professional life arrived early anymore.

He had been reading without much attention, and when the conductor’s voice came through the speakers he looked out the window as if the city had approached him without permission. Warehouses and brick rows slid past in the gray light. Construction cranes stood toward the harbor, their arms fixed against a sky cold enough to snow but not quite willing.

The car was full. Around him passengers began collecting themselves before the train had fully stopped. A student across the aisle struggled with a duffel bag so large that an older woman finally reached up, braced one hand against the rack, and shoved it free. When it dropped into his arms, he looked surprised by the scale of his own decisions.

“You moving home or invading it?” she asked.

The student laughed, embarrassed. “Laundry.”

“That much laundry means your mother failed somewhere.”

Several passengers smiled, and the moment passed into the general shuffle of arrival.

Elias had watched it without quite being in it. One row back. A beat late — which was, lately, most things.

He waited until the aisle cleared. His sister had once told him this was because he liked thinking he was more patient than other people. His mother had agreed. His father had said patience had nothing to do with it; Elias simply liked avoiding crowds. All three were probably right.

His watch had vibrated twice since Wilmington, both times the soft double pulse that meant low-priority review items from the Strategic Continuity Office. He had switched the device to family mode before boarding, which was supposed to filter everything below a genuine emergency. The trouble was that the definition of emergency had quietly expanded over the past eighteen months until it covered most of what his office did. He ignored both pulses and kept his eyes on the window.

Near the back of the car a small girl held her phone flat to the glass, laying animated snow over the real fields sliding past — the genuine brown and white of winter farmland under a low sky — so that the made snow fell across the true ground and the true ground was the part you couldn’t quite see anymore. She watched it as the young watched everything now, comfortably, without the sense that anything had been exchanged. Elias watched her, then looked back out his own window, at the plain unimproved fields, and could not have said why he bothered.

When he stepped onto the platform, the cold met him through his coat.

Baltimore’s winter had no clean sharpness. It carried dampness from the harbor and settled into fabric and joints with quiet persistence. The season’s first snow had covered the city just long enough for people to photograph it, complain about it, and remember where they’d left their gloves. By now most of it was gray slush against the curbs.

Christmas was four days away, and the station had the disorder of travel before a holiday. Parents counted children and bags with equal concern. Business travelers moved through the crowd still half-attached to the cities they’d left. Near the main doors a man in a heavy coat argued cheerfully into his phone about whether anyone in his family had remembered to buy nutmeg.

Washington made every hour feel scheduled, even the hours that technically belonged to him. Baltimore had never been especially interested in scheduling itself. It changed, sometimes too quickly and sometimes not quickly enough, but it kept a stubborn unevenness Elias found easier to trust than cities that had figured out what they wanted to be.

His grandmother had loved that unevenness. She had grown up in a row house not far from the harbor, and even after she moved away she continued speaking of the city as though it were a difficult relative whom strangers had no right to criticize. When Elias was thirteen she had taken him to lunch near the water and stopped afterward in front of an old warehouse whose upper windows were patched with three different shades of glass.

“They fixed the wrong ones,” she had said.

Elias had looked up. “Which ones?”

“The three that didn’t leak.”

He had no idea how she could know that, and she offered no explanation beyond a satisfied little shrug. Years later, after the warehouse became offices and the older windows were replaced during renovation, she reminded him of it whenever he trusted something simply because it looked new.

“New isn’t the same as fixed,” she would say, usually while overcooking something and insisting the pan was at fault.

He had thought about her more than usual on the train down. Not the late version of her, the small woman in the hospital chair who asked the same questions in gentle loops, but the earlier one, broad-shouldered and opinionated and suspicious of anything that came too easily. She had died before AI systems became ordinary enough to require an opinion, which Elias sometimes thought was a mercy. She would have had many, loudly, and they would almost certainly have been more interesting than the ones circulating in his office.

His phone vibrated.

Maggie.

He answered before the second ring.

“Tell me you didn’t miss the stop,” his sister said.

“Hello to you too.”

“That was not an answer.”

“I’m outside the station.”

“Good.”

“You were actually worried?”

“Not worried. Aware of history.”

“I have never missed Baltimore.”

“You once got off at New Carrollton because you were reading.”

“That was twenty years ago.”

“It was hilarious twenty years ago.”

He heard noise behind her: cabinet doors, a burst of laughter, music playing too faintly to identify. The sounds of a house in full operation, something he had almost forgotten the texture of. Then a younger voice cut through the call before Maggie could continue.

“Uncle Eli?”

“Hi, Ava.”

“I have important news.”

“Should I be sitting down?”

“Yes, but Mom says you’re probably standing in the way of people.”

“She knows me well.”

“My bridge survived nineteen pounds.”

“Nineteen?”

“It was supposed to be seventeen, but Grandpa said the textbooks looked lonely.”

From somewhere behind her, Maggie said, “Do not make that sound like a normal decision.”

“It was science,” Ava replied, with the grave certainty of an eleven-year-old who had recently discovered that justification was a tool available to everyone.

Elias laughed. “Congratulations. I assume the bridge has been promoted.”

“It’s in the basement. You have to see it before dinner.”

“Before I take off my coat?”

“If you want.”

“That’s generous.”

Ava lowered her voice, though not enough to prevent Maggie from hearing. “Did you bring presents?”

“There it is,” Maggie said in the background.

Elias could picture his sister exactly: phone wedged between her ear and shoulder, stirring something on the stove while managing two other conversations and almost certainly winning all three. Maggie had always been better at presence than he was. She had chosen the kind of life that required it.

“Get home,” she said.

“My ride is coming.”

“Good. Mom has asked twice whether you’re eating enough.”

“Tell her I’m still recognizable.”

“I won’t lie to our mother this close to Christmas.”

The call ended.

Elias took out his phone to request a car, and a dark sedan was already easing toward the curb before his thumb reached the screen. “Mercer?” the driver said, and he said yes, and got in, and only as the door closed did the small wrongness of it reach him and then, almost as quickly, dissolve: he had not finished asking. Somewhere a system had read the shape of his afternoon — the train arrival, the four days at his parents’, the fatigue in how he’d been moving through the station — and decided, correctly, that the man would want a car now, here, and sent one. He noticed that he was not surprised. Then the thought went where such thoughts went now, which was nowhere he could find later.

A delivery truck blocked half a lane while two men unloaded boxes onto a handcart, in no hurry. Outside the coffee shop a woman balanced four drinks against her chest, nearly lost one, recovered, and accepted the applause of a man waiting nearby as if she had completed a public performance. At the corner a volunteer rang a bell beside a red kettle while a child tugged her father’s sleeve hard enough to bend him toward the bucket.

The child dropped in a coin.

The father dropped in a bill.

The bell kept ringing.

The world, Elias thought, remained full of people doing small unnecessary things that would never appear in any model and yet somehow mattered enormously to the people doing them, and probably to the people nearby, and possibly to more than that. He stopped the thought before it became a brief. He had promised himself he would not spend the visit thinking in work-shaped sentences.

As they moved through the city the traffic thickened. A pharmacy window flashed holiday hours beside a smaller notice warning of delays on imported medications; two customers stood outside reading it with the resignation of people meeting the same problem for the third time that week. None of it looked dramatic. That was how most disruptions entered ordinary life, Elias had found over years of watching — quietly, announced by signs in windows and people buying slightly more than they needed.

The radio moved from a weather update to a brief story about shipping delays affecting consumer electronics and certain medical components from Asia. Taiwan was mentioned once, then again in a more careful tone. The driver reached forward and turned the volume down.

He knew the shape behind the careful tone — two governments that did not want a war, and the two systems that now did most of the work of keeping them out of one, each reading the other across the same dark water. It was the kind of thing he was paid to think about, and he was not being paid this afternoon — but he thought it through anyway, because he had never once been able to leave anything half-understood.

“I’m tired of hearing about problems I can’t fix,” she said.

Elias looked out the window. “I get it.”

The houses grew more familiar as they neared his parents’ street. Brick fronts, narrow yards, porch lights already on. At the end of the block, Mr. Donnelly’s house glowed with its usual excess, every bush and railing covered, the roofline pulsing red and green. When Elias was nine, his father had told him pilots used it to locate Baltimore in fog. He had repeated this to his geography teacher and been gently corrected.

The car slowed in front of his parents’ house, and he stepped out into the cold.

The house looked smaller than it had when he was young, though not diminished. Age had simply corrected his memory of it. The white trim had been repainted since his last visit, probably by his father despite everyone telling him not to climb ladders anymore. A wreath leaned noticeably to the left. His father hung it that way every year because he refused to use a level for what he called temporary decorations. His mother threatened to fix it every year and never quite got to it before Christmas made the question moot for another eleven months.

Before he reached the steps, the door opened.

His mother stood in the warmth of the entryway wearing an apron over a sweater and holding a wooden spoon as if she had come directly from conducting an orchestra.

“There you are,” Elaine Mercer said.

“I was beginning to worry nobody wanted me here.”

“You’re twenty minutes late for being early.”

“That feels like one of Maggie’s categories.”

“She learned from me.”

Warm air rolled out around her, carrying garlic, bread, cinnamon, and the sharper edge of tomatoes that had been left on heat a little too long. The smell stopped him for half a second before he crossed the threshold. Beneath the newer holiday smells was something older and unmistakable, basil, onions, sugar, and that faint bitterness his grandmother’s sauce always had just before she insisted she had meant it that way.

Elaine noticed his expression.

“What?”

“Nothing.”

She narrowed her eyes. “That was not nothing.”

“It smells like Grandma’s sauce.”

“Then pray for us.”

From the kitchen, his father called, “I heard that.”

“You were meant to,” Elaine called back.

Elias laughed and stepped inside.

The house gathered him before the people did. Heat on his face after the cold, the hallway runner shifting under his shoes, a Christmas song from the kitchen speaker interrupted every few seconds by Ava’s voice explaining something with great urgency. The entry wall still held the same arrangement of photographs, though new ones had squeezed into the gaps: Maggie in a graduation robe; Ava holding a soccer trophy almost half her height; his grandparents in a black-and-white photograph taken long before he was born, his grandmother laughing at someone outside the frame.

He stood looking at the photograph for a moment longer than he intended.

Ava reached him first.

“You came.”

“That was always the plan.”

“Mom said plans change.”

“Mom has become very wise.”

Maggie appeared behind her carrying a dish towel, three conversations deep and not yet decided which to finish. She had their mother’s directness and their father’s memory for inconvenient details, a combination that made her both excellent company and a difficult person to argue with.

“I said your plans change,” she said.

“That sounds more accurate.”

“You once missed dinner because a briefing ran long.”

“That was not dinner. That was brunch.”

“It became dinner while we waited.”

His father entered from the kitchen wiping his hands on a towel. Thomas Mercer was seventy-two, broad through the shoulders still, though slower now in the knees. His hands, thick and scarred from decades as an electrician, were stained faintly red from tomato sauce. He had the look of a man who had spent a lifetime solving physical problems and remained mildly suspicious of problems that couldn’t be reached with both hands.

“There he is,” Thomas said. “The man who finally remembered where we live.”

“I brought witnesses. The train arrived.”

“Trains arrive all the time. Sons are less reliable.”

He pulled Elias into a hug, held him half a second longer than usual, then pushed him back by the shoulders and looked him over with the careful attention of someone conducting an inspection he intended to pass off as casual.

“You’re thinner.”

The room reacted before Elias could.

Maggie sighed. Ava grinned. Elaine closed the front door with slightly more force than required.

“You said that to the mailman last week,” Elaine said.

“He looked thin too.”

“He was wearing a winter coat.”

“Could have been hiding it.”

Elias looked at Maggie. “Still doing this?”

“Every year.”

“Every person,” Ava added.

Thomas pointed at her. “You’re growing. That’s different.”

“I know,” Ava said. “I’m supposed to.”

Maggie handed Elias the dish towel. “Since you’re here, make yourself useful.”

“I haven’t taken off my coat.”

“You can be useful in a coat.”

The kitchen had accumulated forty years of decisions: a new induction range beside cabinets whose handles his parents had never gotten around to replacing, a smart refrigerator covered in handwritten notes held by magnets from places they no longer traveled. Cookbooks stacked beside a recipe tablet nobody used, because the cookbooks held handwritten margin notes the tablet couldn’t replicate. Above the window, a small framed print Elias had given his mother eighteen years ago hung slightly crooked, never corrected.

His father stood over the stove stirring sauce in the pot his grandmother had used and his mother had argued against throwing away during every kitchen renovation for thirty years.

“What exactly does your office do?” Thomas asked. Not aggressively. As he asked about most things: as though the answer might confirm a suspicion he had already formed.

“I coordinate between agencies on continuity planning.”

“Continuity of what?”

“Systems. Decisions. Response frameworks for failures that cross jurisdictions.”

Thomas stirred the sauce. “When the Taiwan thing gets worse.”

“Among other things.”

“Your grandfather used to say governments existed to make sure the lights stayed on. Everything else was commentary.”

“He wasn’t wrong.”

“He also thought Nixon was misunderstood, so.” Thomas tasted the sauce, added salt, tasted again. “You think it’ll get worse?”

Elias looked out the window at the narrow backyard, where Ava had apparently built something with sticks and string along the fence line that he could not identify from this angle. “I think it’s been getting worse slowly enough that people keep being surprised by how far it’s gone.”

Thomas nodded as though this was the answer he’d expected. “That’s how most things go wrong.”

Elaine came in from the dining room carrying a centerpiece she had apparently decided to reconsider. “Are you two solving it?”

“Having a preliminary consultation,” Elias said.

“Charge by the hour,” Thomas suggested.

“I would have retired already,” Elias said.

She set the centerpiece on the counter and studied it with the expression she reserved for objects that had disappointed her. “Maggie said you haven’t been sleeping.”

“Maggie is an unreliable narrator.”

“Maggie talked to your assistant.”

Elias turned from the window. “She talked to my—”

“She was worried.”

“I sleep fine.”

His mother looked at him with the particular attention that had survived forty years of his attempts to appear more confident than he was. “You look like a man who has convinced himself that’s true,” she said, and picked up the centerpiece and carried it back to the dining room.

Thomas kept his eyes on the sauce.

“She’s not wrong,” he said.

“I know.”

“You could take the week.”

“I can’t take the week.”

“You could try.”

Elias found a cutting board and a knife and started on the bread without being asked. The familiar motion of it was a small relief. “I’m here until the twenty-sixth. That’s something.”

“It is,” Thomas agreed. He did not say more than that, which was its own kind of generosity.

Ava appeared in the doorway with the energy of someone who had been waiting a reasonable amount of time and had decided the wait was now complete.

“Can I show you the bridge now?”

“Before dinner?” Elaine called from the other room.

“I already asked him. He said yes.”

“I said it was generous of you to offer,” Elias said.

“That means yes.”

Maggie appeared beside her. “Take him. It’ll take a couple of minutes and she’s been holding it together since Tuesday.”

Ava tugged his sleeve. “Come on. You don’t even have to take off your coat.”

The basement had always been his father’s domain, a long room of workbenches and pegboards and labeled drawers that contained exactly what their labels promised, a discipline absent from every other room in the house. Thomas had spent thirty years of evenings down here, fixing things that didn’t strictly need fixing, building things the family didn’t strictly need, and teaching Elias and Maggie that most objects rewarded patience and most problems had at least one solution that didn’t require throwing anything away.

Ava had set up in the far corner, near the old furnace that ticked through its cycles like something with opinions about temperature. The bridge was a model about eighteen inches long, constructed from wooden craft sticks, white glue, and what appeared to be a considerable quantity of dental floss serving as cable stays. It sat on two small sawhorses, and above it hung a hand-lettered sign on notebook paper: MERCER BRIDGE STRESS TEST — PASSED 19 LBS.

“What kind of bridge is it?” Elias asked.

“Cable-stayed. With modifications.”

“What modifications?”

“I added a second layer to the deck because the first one cracked under twelve pounds. Grandpa helped me figure out the bracing.”

“He didn’t build it for you?”

Ava looked briefly offended. “No. He just explained the load distribution. I figured out the cables myself.”

“By trial and error?”

“By trial, error, and three YouTube videos.”

He crouched down to look at it from the side. The work was careful. Uneven in places, but careful. The deck had a slight bow at its center that probably wasn’t in the original design but had survived nineteen pounds regardless.

“What went wrong first?” he asked.

Ava sat on the old stool nearby. “The anchor points. I glued them wrong and they pulled out when I added weight. Then I had to rebuild them and wait for everything to dry, which took a whole day, and Grandpa said not to touch it, which was very hard.”

“He says that a lot.”

“He says patience is a skill and I have to practice it.”

“He told me the same thing when I was about your age.”

“Did it work?”

Elias looked at the bridge. “Eventually.”

Ava considered this. “He said you built a bookshelf down here once that fell apart.”

“Three times. The fourth one held.”

“Is that when you learned patience?”

“That’s when I learned to read the instructions first.”

She laughed, and the sound bounced around the low ceiling of the basement and reminded him of something he couldn’t immediately place. Then he placed it: his sister, at roughly the same age, finding something funnier than it probably was and not being embarrassed about it. He had forgotten how much Ava sounded like Maggie.

Ava ran a line of glue along a joint, quiet for a moment. Then, not looking up: “Why can’t you just let China have Taiwan? Or — why can’t everyone leave it alone?”

He started to give her the conference-room answer — commitments, credibility, the cost of letting the first piece go — and stopped, because he could not say it to a kid with glue on her fingers, and because it was the kind of answer that explained everything and settled nothing. “I don’t really know,” he said. “Somebody decided a long time ago that we couldn’t. And now everyone mostly just keeps the decision going.”

She weighed this with the seriousness she gave a load-bearing joint. “That’s a dumb rule.”

“Yeah,” he said. “It might be.” He looked back at the bridge.

“What are you going to do with it?” he asked.

“I don’t know yet. Maybe see how much more it can hold.”

“You could enter it in a competition.”

“Grandpa said that too.” She traced one of the cable stays with a careful finger. “I might just keep it. It took a long time.”

He nodded. There was something in the simplicity of that, keeping something you had made because it had cost effort and had held, that he found difficult to argue with.
