Julian waited until Silas looked away before he checked the key again.
The symbol engraved into its head was small enough to miss if someone wasn't looking for it. A circle divided by a vertical line.
The same mark hidden inside Mara's silver ring.
He remembered the ring on her finger. The way she had held his hand when she gave it to him. The way she had looked at him as though she were saying goodbye without wanting him to notice.
Follow the mark.
He had assumed it was a clue about the black case.
Now he wasn't certain.
"Where are we going?" Silas asked.
Julian slipped the key into his pocket.
"Somewhere you can't follow."
Silas's jaw tightened.
"You're not walking into another trap alone."
"Then tell me what the key opens."
Silas didn't answer.
Julian nodded slowly. "That's what I thought."
He started walking.
Silas followed.
The streets around Old Meridian Station were nearly deserted. A few taxis passed beneath the streetlights, and the shops along the road had already closed. Julian kept his hands in his pockets, feeling the hard outline of the key against his fingers.
He could have demanded that Silas leave him alone.
He could have tried to lose him in the streets.
Instead, he allowed Silas to follow for three blocks before turning into a narrow alley.
At the far end stood an old public telephone booth.
Its glass panels were cracked. Dust covered the metal frame, and the receiver hung from its cord like something abandoned years ago.
Julian stopped beside it.
Silas glanced at the booth. "What are you doing?"
"Testing something."
"Julian."
"You know, you say my name like it should be enough to make me stop."
Silas fell silent.
Julian studied him.
"Did it work before?"
"Yes."
The answer came too quickly to be a lie.
Something tightened in Julian's chest.
"How often?"
Silas looked away.
"Often enough."
Julian wanted to ask what kind of man he had been before the accident. What kind of relationship required one person to say a name and the other to surrender.
But he had learned that questions about their past often became another opportunity for Silas to decide which parts of himself to reveal.
So Julian opened the telephone booth instead.
Inside, beneath the metal shelf, someone had scratched the same symbol into the wall.
A circle.
A vertical line.
Below it were three words.
WHEN HE RETURNS.
Julian touched the inscription.
The moment his fingers met the metal, an image flashed through his mind.
His own hand.
Blood running down his wrist.
A door closing.
And Silas standing on the other side of it, pounding against the surface.
Julian pulled back sharply.
"What's wrong?" Silas asked.
"Nothing."
"You're shaking."
"Then stop watching me."
Silas stepped closer but didn't touch him.
For a moment, Julian thought he might argue.
Instead, Silas looked at the inscription.
The color drained from his face.
Julian noticed.
"Have you seen this before?"
Silas said nothing.
"Silas."
"Yes."
"When?"
Silas's eyes remained fixed on the words.
"The night you disappeared."
The answer settled heavily between them.
Julian stared at him.
"You were here?"
"I searched everywhere for you."
"That's not what I asked."
Silas finally looked at him.
"Yes. I came here."
"And?"
"There was nothing left."
Julian turned back to the inscription.
"When he returns."
He ran his thumb over the scratched letters.
"Who wrote this?"
Silas hesitated.
"You did."
Julian closed his eyes.
Another fragment surfaced.
A room lit by a single lamp.
His own voice, low and exhausted.
"If I come back, don't let me open it."
Then a second voice.
Silas's.
"What if you need what's inside?"
And Julian answering:
"Especially then."
The memory vanished.
Julian opened his eyes.
Silas was watching him with an expression he couldn't understand.
"What is it?" Silas asked.
Julian swallowed.
"I told you not to let me open something."
Silas nodded once.
"Yes."
"What was it?"
"I don't know."
Julian almost laughed.
"You're asking me to believe that you searched for me for three years, found this place, saw my warning, and never discovered what it meant?"
"I searched for you. I didn't find this until after you were gone."
"And you didn't investigate?"
"I tried."
"What stopped you?"
Silas's expression hardened.
"You did."
Julian stared at him.
Silas reached into the inside pocket of his coat and removed a folded piece of paper. It was old, its edges softened by handling.
He held it out.
Julian took it carefully.
The handwriting was his.
He recognized the sharp angle of the letters, the way he crossed his sevens, and the heavy pressure that left grooves in the paper.
There were only two sentences.
If I return without remembering, let me choose again.
Do not mistake my fear for permission.
Julian read the words twice.
Then a third time.
Something about them felt worse than a threat.
They sounded like a man who knew exactly what would happen to him and had tried to leave himself a way out.
"What did I choose?" Julian asked.
Silas's voice was barely audible.
"I don't know."
Julian looked at him.
For the first time, he believed that answer might be true.
Not because Silas had suddenly become trustworthy, but because the uncertainty in his eyes looked different from his usual calculated silences.
Silas wasn't withholding a known answer.
He was afraid of the answer they might find.
Julian folded the paper and slipped it into his pocket beside the key.
"Where did you get this?"
"From the person who gave it to me."
"Who?"
Silas looked at him.
"Adrian."
Julian's fingers went still.
Adrian.
The name on the phone. The person who had arranged the meeting involving the black case. The person who had apparently instructed Silas not to let Julian remember the river.
"How long have you known him?"
"Longer than I've known you."
The answer surprised Julian.
"Then why was he arranging meetings for me?"
"Because you trusted him."
"And you didn't?"
"No."
"Yet you let me work with him."
Silas's expression changed.
"You weren't someone I could control by simply telling you no."
Julian studied him.
"Was that why you loved me?"
Silas went completely still.
Julian hadn't planned to ask the question. It had simply emerged, sharp and ugly, from the space between them.
Silas looked as though he wanted to answer.
But before he could, Julian's phone vibrated.
An unfamiliar number.
UNKNOWN: Stop asking Silas about the river.
Julian's expression hardened.
Another message appeared.
UNKNOWN: He wasn't the person you were supposed to meet that night.
Julian stared at the screen.
He typed a reply.
JULIAN: Who was I supposed to meet?
The response arrived almost immediately.
UNKNOWN: The person who gave you the case.
Julian's pulse quickened.
JULIAN: Adrian?
Three dots appeared.
Disappeared.
Then the phone rang.
Julian answered without speaking.
For several seconds, there was only static.
Then a man's voice came through, distorted and distant.
"You're asking the wrong questions again, Locke."
Julian's grip tightened around the phone.
"Who is this?"
"You have the key?"
Julian didn't answer.
The man gave a short, humorless laugh.
"Of course you do. You always were good at finding things you shouldn't touch."
"What does it open?"
"A door you locked yourself."
"Where?"
"Ask Mara what she did with the other half."
The call ended.
Julian lowered the phone slowly.
Silas had heard enough to understand that something had changed.
"What did they say?"
Julian looked at him.
"They said Mara has the other half."
Silas's face went blank.
Not confusion.
Recognition.
Julian stepped closer.
"What aren't you telling me?"
Silas stared at the phone in Julian's hand.
"Nothing that will help you."
"That isn't your decision anymore."
"I know."
"Then tell me why you reacted when I mentioned Mara."
Silas's silence lasted long enough to become an answer of its own.
Finally, he said, "Because Mara was supposed to make sure you never came back."
Julian felt the words like a blow.
"Make sure I never came back from where?"
Silas looked at him, and for one terrible second, Julian saw the same expression he had seen at the station when the scarred man named him.
Fear.
"The night you disappeared," Silas said.
Julian took a step back.
Mara had claimed she watched him die.
The scarred man had pulled him from the river.
Adrian had arranged a meeting.
And Silas had been searching for him.
Every person had offered a different piece of the same night, yet none of those pieces fit together.
Julian reached into his pocket and closed his hand around the key.
He had spent weeks believing that remembering would give him back his life.
Now he was beginning to suspect that the person who had lost his memories had understood something the person he was today did not.
Some truths were dangerous because of what they revealed.
Others were dangerous because of what they made a person willing to do.
Julian looked at Silas.
"Take me to Mara."
Silas shook his head.
"No."
Julian's expression went cold.
"Careful."
"She's not safe."
"Neither are you."
Silas flinched almost imperceptibly.
Julian turned toward the street.
"Then you should have told me the truth before I had to find it myself."
He walked away without waiting for Silas.
This time, Silas didn't follow immediately.
Julian had taken only a few steps when his phone vibrated again.
A message from A.
A: You found the first lock.
Julian stopped.
JULIAN: Mara has the other half.
The reply took longer this time.
A: No. Mara has what you left with her.
Julian's stomach tightened.
JULIAN: What's the difference?
A's answer appeared.
A: The key opens the door.
A: The other half tells you why you locked it.
Julian stared at the screen.
Then another message arrived.
A: And Julian?
He waited.
A: If Mara asks whether you remember the promise, don't answer her.
A final message appeared beneath it.
A: You made that promise to me.
Julian stopped breathing for a moment.
He read the message again.
Then he looked over his shoulder.
Silas was still standing beside the abandoned telephone booth, watching him from beneath the streetlight.
For the first time, Julian wasn't certain which of them had been left behind that night.
