Carter opened the door.
The rain had thinned to a mist. Standing on the stone step was a woman in her fifties, wrapped in a gray raincoat that had seen better decades. Short hair, no makeup, no jewelry. She looked like a dockworker's wife, or a nurse coming off shift, or someone's mother on her way to market. Nothing about her said threat.
She was holding a small package wrapped in oilcloth.
"Who are you?" Carter said.
"I'm the one who knocks," she said.
"Who gave you the knock?"
"A man who used to live here."
"Used to?"
"He left three months ago." She held out the package. "He said if you came back through, I should give you this."
"Who said?"
"Marcus."
The name landed and stayed. Carter didn't move. Rain ran off the edge of the doorway and pooled on the stone at his feet. Behind him, Rook had gone still.
The woman held the package steady. She didn't look at Rook. She didn't look past Carter into the sacristy. She looked only at him.
"You're not going to ask me in," she said. Not a question.
"Should I?"
"No." She set the package on the step. "He said you wouldn't. He said you'd take the package and close the door and figure out what it means. He said to tell you the answer's in the book."
"What book?"
"The one in the package." She pulled her coat tighter. "I'm going home. The rain's getting worse."
She turned and walked away. She didn't hurry. She didn't look back. Her footsteps faded into the mist, and then she was gone, and the alley was empty.
Carter stood in the doorway with the pistol in his hand and the package on the step.
"Don't touch it," Rook said.
He picked it up.
"Carter."
He carried it inside. Yara had already barred the door again. Rook was on the bench, pale, her arm wrapped tight. Blood had soaked through the bandage but it had stopped running.
Carter set the package on the small table. He pulled the oilcloth back.
Inside: a notebook, a photograph, and a key.
He picked up the photograph first.
Three people, standing in front of a building. Bucharest, 2016. A sunny day. They were all in their early thirties. Marcus was on the left, a head taller than Carter, dark hair, a smile that looked like it cost him something. Eleanor was in the middle, blonde, younger than she looked now, arm around Marcus' shoulder. And Carter was on the right, arms crossed, not smiling.
They looked happy. They looked like a team.
Carter set the photograph down.
He picked up the notebook. Black cover. Worn at the corners. A rubber band held it closed.
He opened it.
The handwriting was Marcus's. He knew it the way he knew his own. The slant. The pressure. The small loop in the letter g.
He turned the pages.
Entries. Dates. Locations. Short, professional, no wasted words.
11 Feb. Subject moved to Cell Block D. No visitors.
27 Feb. Subject interviewed by Control. Duration 42 minutes. Outcome: none.
14 March. Subject's blood work shows markers consistent with Program Hale. Further testing needed.
Carter kept turning. The entries went on. Every date. Every movement. Every breath he had taken in that prison for three years. Marcus had been logging him the entire time.
"You knew," Carter said, without looking up.
"I didn't know it was him," Rook said. "I knew there was a file. I didn't know who kept it."
"You knew there was a file."
"Yes."
"About me."
"Yes."
"For how long?"
Rook was quiet. Then: "Six months."
Carter looked at her.
"Six months," he said.
"Yes."
"You've known for six months that someone was tracking my time in prison, and you didn't tell me."
"I didn't know it was you until three weeks ago."
"You knew there was a subject. You knew there was a program. You knew there was a man on the inside logging every detail. And you didn't say anything."
"No."
"Why?"
Rook looked at him. Her face was pale from the blood loss, but her eyes were steady.
"Because the file was the only proof that you were still alive," she said. "If I told you, you'd want to see it. If you saw it, you'd want to find him. If you found him, you'd get yourself killed. So I didn't tell you."
"That's not a reason."
"It's the only one I have."
Carter looked at her for a long moment. Then he turned the pages.
The entries continued past his imprisonment. Past his release. Past his arrival in Port Callow. There was an entry dated three weeks ago — the day Rook had been assigned to him.
3 Sept. Partner assigned. Designation: Rook. Recommend no deviation from plan.
Then entries for the last three weeks. Daily. Almost hourly.
5 Sept. Subject inserted into Callow. No observation.
6 Sept. Subject met handler Control. Debrief not logged.
8 Sept. Subject's health stable. No incidents.
Carter turned the page.
Then he stopped.
The handwriting had changed.
Same shape. Same slant. Same loop in the g. But messier. Rushed. The writing of a man who was writing in the dark, or in a hurry, or under stress.
It was his own handwriting.
He read the entry.
12 Sept. Left safehouse at 0200. Took paper from drawer. Wrote line on existing log. Returned paper. Slept.
He turned the page.
13 Sept. Wrote second line at 0345. Subject unaware. No memory recall. Recommend continued trials.
14 Sept. Wrote third line at 0410. Same result.
Carter looked at the dates. Three days ago. Four days ago. Today was the fifteenth.
The entries stopped at yesterday. The handwriting was his.
"Marcus didn't write these," he said.
"No," Rook said.
"I did."
"Yes."
"Under conditioning."
"Yes."
"But Marcus was writing the same notebook before that."
"Yes."
"So Marcus wrote the first two years. Then the handwriting changes. Then it's mine."
"Yes."
"Where's Marcus?"
"Gone."
"Gone where?"
"Nobody knows. He was in Bucharest until April. Then he stopped filing. Then the entries started appearing in your hand."
Carter set the notebook down.
He picked up the key. Small. Brass. No markings. Nothing about it suggested a purpose.
"What's this for?" he said.
Rook looked at it. She didn't answer.
"Rook."
"I don't know."
"You recognize it."
"I recognize the type. It's a safety deposit key. Old style. Any bank in the Lower Shelf would have a hundred of these."
"Which bank?"
"I don't know."
Carter set the key down.
Yara had been quiet through all of this. She was sitting in the corner of the sacristy with her hands in her lap. Now she spoke.
"St. Anselm's keeps a deposit box," she said.
Carter looked at her.
"For the parish," she said. "Documents. Deeds. Old things no one needs until they do."
"Why are you telling me this?"
"Because Marcus used to come here," Yara said. "Before he left. He'd sit in the back pew and he'd say nothing for an hour, and then he'd get up and leave. Once, I asked him what he was praying for. He said he wasn't praying. He said he was leaving something behind."
"Where?"
"In the box." Yara nodded at the key. "He told Father Michael it was for a man who might come back through. He told him the man would have the key."
Carter looked at the key in his hand.
"Father Michael," he said.
"He's not here."
"Where is he?"
"Rome. He left last week. He said he needed to see the Pope. I don't think he was joking."
Carter stood up.
Rook stood too. She swayed, one hand on the bench, but she stayed upright.
"Not tonight," she said. "Wait for daylight."
"Daylight's six hours away."
"Six hours is enough for the shooters to find this place. It's not enough for us to walk into a church in the middle of the night with no idea what's waiting."
"Marcus said the answer's in the book."
"He said the answer's in the package." Rook nodded at the key. "That's the box."
Carter looked at her.
"You know what's in the box," he said.
"I don't."
"You know something."
"I know that Marcus was careful. I know he wouldn't have left a key unless the box mattered. I know Father Michael is gone because someone told him to leave."
"Who?"
"I don't know." Rook's voice was flat. "I know less than you think."
The rain had started again. It tapped on the roof of the sacristy in slow, measured beats. Somewhere out in the city, a church bell rang twice. Two in the morning.
Carter pocketed the key. He put the notebook and the photograph back in the oilcloth and wrapped it up. He slid the package into his jacket.
"We go at first light," he said.
"That's four hours," Yara said.
"Then we sleep two. I want to be at the church before five."
Rook sat back down on the bench. She didn't argue. Her eyes were closed. Her breathing was slow.
Yara poured water into a small cup and held it out to her. Rook drank without opening her eyes.
Carter walked to the door and sat down against the wall facing it. He put the pistol in his lap. He didn't close his eyes.
Yara watched him.
"You said you weren't going to ask her in," she said.
"I didn't."
"You didn't ask me either."
"You were already inside."
"I was." Yara sat down on the bench opposite him. "Do you know who sent her?"
"Eleanor."
The name landed and stayed. Yara's face didn't change, but something behind her eyes shifted. She looked at Carter the way she'd looked at him at the fish market — flat, careful, no wasted motion.
"You know Eleanor Sable," she said.
"I worked for her."
"You worked for her for how long?"
"Six years."
"Then you know she doesn't send messages."
"She sent one tonight."
"She sent a package."
"That's a message."
Yara considered that. Then she nodded, slowly.
"Marcus said you were clever," she said. "He said you'd see things other people missed."
"Marcus talked about me?"
"He talked about a lot of things." Yara leaned back against the wall. "He sat in the back pew every Sunday for two years. He never took communion. He never prayed. He just listened. And afterward, sometimes he'd stay and we'd talk."
"About what?"
"About a man he used to work with. About a job that went wrong. About a thing he did that he couldn't take back." She looked at Carter. "He never said your name. But I knew."
"How?"
"Because he described you." Yara folded her hands. "He said you were the kind of man who could walk into a room and know where the exits were before he knew who was inside. He said you were steady. He said you were loyal. He said you were the only person he ever trusted with something he was afraid of."
"Afraid of what?"
Yara didn't answer.
She stood up and walked to the small altar at the back of the sacristy and touched the edge of the cloth. She didn't turn around.
"He said the day would come when you'd walk through that door," she said. "He said I'd know you because you'd ask the right questions and you'd never once ask the wrong one. He said not to tell you anything until you asked."
"Asked what?"
Yara turned around.
"Whether he was still alive," she said.
Carter looked at her.
"Well," Yara said. "You haven't asked yet."
The rain drummed on the roof. Rook's breathing had evened out. Somewhere beyond the walls, the city was quiet in a way it never was during the day — no cranes, no trucks, no market noise, no shouting. Just the water, and the wind, and the low hum of a place that had learned to sleep through anything.
Carter looked at Yara.
"Is he still alive?" he said.
Yara's face didn't change.
"I don't know," she said. "But I know what he told me. He told me if you ever asked, I should tell you one thing."
"What?"
Yara walked back to the bench and sat down. She looked at the floor between them.
"He told me the man you're looking for isn't the man who wrote the notebook," she said. "The man you're looking for is the man who erased it."
Carter didn't move.
"Erased it," he said.
"The last two years. The entries in your hand. You didn't write those because you were confused. You wrote them because someone made you. Someone who knew Marcus. Someone who knew how he wrote. Someone who wanted you to think he was still out there, still watching, still in the game."
"Then he's dead."
Yara didn't answer.
"Yara."
"I don't know if he's dead," she said. "I know he's not writing. I know he stopped. I know the man who's writing now isn't Marcus."
"Then who is it?"
"I don't know." She looked up. "But I know one thing."
"What?"
"Whoever he is, he knows you."
Carter looked at her for a long moment. Then he looked at the door. Then at Rook, asleep on the bench with the bandage on her arm and the pistol under her hand.
Then at the package in his jacket, the key inside it, and the church waiting four hours away.
He stood up. He walked to the small window and looked out at the mist and the water and the dark.
Somewhere out there — in the Cut, in the Upper Shelf, on a boat crossing black water — someone was waiting for him. Someone who knew Marcus. Someone who knew him. Someone who had spent two years writing in a dead man's hand just to leave
