The fifth of seven came in through the eastern port at oh-four-twenty in the morning, three days late, in a fishing boat she had bought outright and would burn in the harbor before sunrise.

She walked off the dock with a single duffel bag and no insignia.

She was forty-six years old. She was thin in a way that suggested it was an operational choice, not a metabolic one. Her hair was gray at the temples and dark in the back, pulled into a low braid. She wore a long dark wax coat that hid the equipment underneath it. The Hacker had a file on her that was eleven megabytes and almost none of it was photographs.

Her name was Nadiah.

Caleb met her at a noodle stall two blocks from the port. She was eating when he arrived. She did not stand. She did not stop eating.

"Sit," she said.

He sat.

She pointed with her chopsticks at the stool beside him. "Eat."

"I’m not hungry."

"Eat anyway. Your bypass uses sugar. You have a long day tomorrow. The owner here makes a soup that is forty percent broth fat. Drink the broth. Don’t ask what’s in the meat."

He ordered the soup.

She kept eating.

She watched him for the first six minutes without speaking.

She studied the line of his collar where the harness rode. She checked his hands, his eyes, and the place on his coat where the dampener sat in the inside pocket. She never held his face directly for more than a second.

When his soup arrived, she said:

"Show me your ribs."

"In a noodle stall."

"The owner is paid. The other table is paid. The street outside is mine until oh-five-hundred. I have flown for thirty-one hours and I am not going to a safe house before I inspect the marks. Show me your ribs."

He lifted his shirt. She leaned across the table and studied the silver. She did not touch. She sat back.

"How did Tali do that?"

"She rebuilt the bypass three days ago."

"That is not what changed the color. The bypass cannot change the color. The bypass is a containment device. The color is the carriage layer. Your carriage layer reset. That is not a Tali rebuild. That is a Twelfth-tier event. Something happened during the rebuild that was not the rebuild. Did anything fight you inside the bypass operation?"

"My brother talked to me through it."

"Your brother carries a piece of the Twelfth."

"Yes."

"That is what changed the color. Your piece touched his through the attention the call carried. The comm was only the wire. Pieces do not need physical proximity. They need attention. He gave you attention for thirty-one minutes. The two pieces are now in coordination. That is what the silver is. You and your brother are operating on the same frequency now. You will be in the chamber together on Day Sixteen. You will not be separable from him inside the chamber math until both pieces are returned."

Caleb did not move.

She picked up her chopsticks again and ate for another minute.

She said: "I am sorry. I did not know if your father had told you."

"He has not."

"He will," Nadiah said. "Tomorrow night."

The bridge statue came up at the seventeenth minute.

"Soma told me about the one at the bridge. The smaller one. The one with the wrong proportions. The one that called you Father."

"Yes."

"That one is yours."

Caleb set his spoon down. "Mine."

"You made it. On the night you do not remember, when you went to sleep in a medical bay on a Sunday and woke up on a rooftop on Tuesday. The piece in you did work that night. Some of that work was external. Your body shed a residue that walked away from you. The residue has been walking since. It found you at the bridge because your silver lit. It will find you again before Day Sixteen. You will need to absorb it back. Your father has a procedure for it. He has been holding the procedure for the last sixty-two days, waiting for the residue to surface where he could direct you to it. The bridge was the surfacing."

"How do I absorb it back?"

"You will touch it. It will come into your hand. It will go through your hand into your sternum. It will hurt. You will not lose consciousness. It will take eleven seconds. Your father will be with you when you do it."

She paused, then nudged the bowl closer with two fingers.

"Eat your soup."

He ate while she watched to make sure the order became calories and not just obedience.

She did not eat the rest of her noodles.

She put her chopsticks down.

"Listen to me. I do not have very many minutes left in this city before someone the executives have hired sees me. I want to give you three things while I have them."

"First. The silver makes you faster. You have noticed. It will keep getting faster. By Day Sixteen you will move at a speed your father did not move at when he was your age, and which I have never moved at, and which Soma cannot move at anymore. Use the speed in the chamber. Keep it hidden before the chamber. The executives have ways of measuring rate that they have not deployed yet. If you move at silver speed in the open before Day Sixteen they will know what you are."

"Second. The brother. He will say yes tomorrow night. Your father will not ask the question well. Your father will ask it like a man ashamed of the question for fifteen years. The brother will answer it like a man who has been ready for it. You will be in the room. Your job is not to argue. Your job is to be in the room. Be in the room."

"Third. The chamber. There is a moment in the operation when your father will be at the seal, the Mimic at the marks, you at the dampener, and your brother at the plinth. In that moment, if any one of the four perimeter operators fails, the operation fails. Those four are me, Soma, Iseul, and Olamide in Lagos. We are the perimeter. The four of you are the core. Your job is the dampener. Twelve seconds. One press. Do not press it before the marks go dark or after the seal closes. Twelve seconds. You will know the window. Your father will not call it out. He will be busy.""

She picked up her chopsticks and finished the soup.

"Good?"

"Yes."

"Pay for me." He paid, and she stood up.

She put her hand on his shoulder briefly.

She did not say anything else.

She walked out of the noodle stall and into the street and around the corner toward the docks where her fishing boat was burning, and Caleb did not turn around to watch her go.

After two minutes, the Hacker came on his comm.

[Hacker: Iseul is in the air. He landed at the western field at oh-five-twelve. Soma has him at the safe house already. Nadiah is going to ground at the eastern docks. Olamide is patched in through the Lagos channel. Lagos is hers tonight. Tomorrow we have five of seven in coordination. The other two will not be told. Your father has been very clear about that.]

"Two more never told."

[Hacker: One never told, one told on Day Fifteen if we get that far. Your father has a reason. I have not been given the reason. He has not been given the reason either. The reason was written into the plan by someone who is not in the room. Your father has been carrying out a plan that someone else wrote. He has been doing it for forty-six years. He has not told me who.]

"Henry wrote it."

[Hacker: Henry wrote it. Yes. Your great-grandfather wrote the plan in nineteen seventy-seven. He gave it to his son. His son added pages. His son’s son added pages. Your father has added the last pages. The plan is older than your father. You are reading the last twenty pages of a document written by four generations of Mercers and revised by the people they pulled into the work. I am telling you because I think you should know that on Day Sixteen the man at the seal is not the first architect. He is the last carpenter. There is a difference.]

He sat with the soup bowl in front of him.

He drank the last of the broth.

It was forty percent fat. It was hot. It was good.

He paid for his own meal and left a tip larger than the meal.

He walked back to the car.

Iris was at the wheel. She had been listening.

"Drive."

She drove.
