Kuramoto gives me a room.
Not in the building below Kasumigaseki. Somewhere else, a residential address in Yanaka ward that he writes on a piece of paper and hands to me without explanation, which means it's the kind of address that doesn't benefit from explanation. A place that exists in the gap between his official capacity and the things he does because the official capacity isn't sufficient.
Rei takes the rental. Nishida takes his car. They both have things to do before midnight and neither of them tells me specifically what, which is either operational security or the mutual understanding that the fewer direct connections between our movements in the next seven hours, the better.
I take a taxi alone for the first time since this morning.
The Yanaka address is a narrow house on a street that has resisted the development pressure surrounding it, wooden frontage, a small garden that someone tends carefully, the particular quality of a space that has been inhabited by the same person for long enough that it has absorbed their habits. The key is under a ceramic pot shaped like a tanuki. Kuramoto's instructions were specific about that, which means he's used this place before for exactly this kind of purpose.
I go in.
The house is clean and quiet and smells like cedar and old paper. A single room with a futon, a low table, a kitchen alcove. A window looking onto the garden. I sit at the low table and I put the waterproof bag in front of me and I take out the burner phone.
It needs charging.
I find a cable in the kitchen drawer, the kind of universal cable that ends up in kitchen drawers everywhere in the world regardless of country or culture, and I plug the burner in and I sit and I wait for it to reach enough charge to turn on.
While I wait I look at the garden through the window.
It's evening now, the sky above the garden walls going dark at the edges. A persimmon tree in the corner, fruit still on it, orange against the gray. Something about the tree produces the same sensation as the bar lock combination and the taxi fare from Kōtō ward, the muscle memory residue of something seen many times before.
Saitō knew this garden.
I don't pursue it. It'll surface or it won't and forcing it produces nothing useful.
The burner powers on at 7:43.
It's an older model, the interface simple, the kind of phone that does three things and does them without complication. Messages, calls, contacts. One contact saved. No name, just a number with a Tokyo prefix.
Minami.
I go to the sent messages.
One sent message. Timestamped 21:34 on the night of the murder. Sent ninety minutes before Mizore's estimated time of death. Sent, I note, approximately two hours and ten minutes before Minami sent the third message to Saitō's regular phone. The message that said: I'm sorry. I tried to warn you in time.
I read what Saitō sent at 21:34.
They're already inside. Don't come to the meeting. Get out now. Everything is on the drive. Use it without me if you have to. I'm going to try to reach her first.
I read it three times.
Then I sit back and I look at the persimmon tree in the garden and I rearrange the entire night of the murder around this single sent message.
Saitō knew.
Not after. Before. He knew at 21:34 that the apartment had been compromised, that someone was already inside, that the plan to meet Mizore at 22:00 had become a trap. He sent a warning to Minami telling them not to come. He told them the drive had everything. He told them to use it without him.
And then he said: I'm going to try to reach her first.
He went back.
Saitō received the same kind of warning he sent. Something, some signal, some piece of intelligence he'd been tracking, told him at 21:34 that the evening had turned. And instead of running, instead of disappearing the way someone with four years of Ryūsei training and eighteen months of careful survival instinct would disappear, he went back to the apartment to warn Mizore.
He was too late.
Or not too late enough. He arrived and found her dead and whatever happened after that, the confrontation, the struggle, the strangulation that was supposed to finish what started with Mizore, something in this body refused to complete the sequence. Something held on.
And I fell into the space that holding on created.
I sit with this for a long time.
The garden darkens outside. The persimmon tree becomes a shape against the sky. I think about a man who spent four years becoming something functional and cold and useful to an organization that treats people as instruments, and then spent eighteen months trying to become something else, and then on the last night of his attempt walked back into a trap to warn a woman he'd been feeding information to for six weeks.
That's not strategy.
That's not the tactical calculation Nishida described. That's not the man who reads situations in thirty seconds and identifies the three most dangerous elements in order of priority.
That's something else.
I pick up the pre-paid phone and I call Nishida.
He picks up on the first ring. "You're at Kuramoto's place."
"Yes. I found a charged cable for the burner." I pause. "There's a sent message. Timestamped 21:34. He knew the apartment was compromised before the meeting. He warned Minami not to come." I pause again. "Then he went back anyway."
Silence on the other end.
"He went back," Nishida says. Not a question.
"To warn Mizore. He says in the message that he's going to try to reach her first." I look at the burner screen. "He didn't make it in time. But he tried."
A long silence. The kind that happens when a person is reconstructing something they thought they understood.
"That's not what I expected," Nishida says finally.
"What did you expect."
"I expected him to run." A pause. "Every scenario I ran in my head for what happened that night, every version, he runs. He gets the signal, he takes the cache, he disappears. That's Saitō. That's how he survived four years inside something that kills people for knowing too much." Another pause. "He didn't run."
"No."
"Because of her," Nishida says. Not Rei. Mizore. "Because he'd been giving her information for six weeks and when it turned he couldn't leave her to it."
I think about the letter on the table in Bunkyō ward. The sentence about cowardice. About holding back the last thing that was his because he wasn't ready to give it away. About how the distance he kept from the investigation was the last form of protection he could offer and how he knew it wasn't really protection.
He knew what he was doing when he walked back in.
He knew it wasn't strategy.
"Does Rei know," Nishida says.
"Not yet."
A pause. "Tell her before midnight. She needs to go into the Yanaka meeting knowing who Saitō was at the end. Not who she thought he was." He pauses. "It'll matter for how she reads Minami."
I don't ask him why he thinks it'll matter. I think I know.
I end the call.
I sit with the burner phone and the pre-paid phone and the waterproof bag and the cedar and old paper smell of a house belonging to someone else's careful life, and I think about what it means to walk back into a trap for a person you've been keeping at careful distance.
Then I stop thinking about it because the category marked later is becoming very full and some things in it are beginning to press against the label.
At 9:15 I call Rei.
She picks up on the third ring. Background noise, a train station or somewhere similar, the ambient sound of people moving.
"Where are you," I say.
"Shinjuku. I've been to see the forensics consultant again. She has preliminary results." A pause. "The body was moved forty minutes post-mortem. The positioning was deliberate. Whoever arranged the scene knew forensic lividity patterns and worked against them." A pause. "It took time. Someone spent time in that apartment after Mizore died making it look right."
"Which means the strangulation attempt on Saitō happened before she died."
"Or simultaneously. Two separate actors in the apartment at the same time." Her voice is precise, clinical, the investigation register. "The blood transfer on Saitō's hands is consistent with contact not with the act of stabbing. Someone put the knife in his hands after he was incapacitated."
"He was unconscious when she died."
"Almost certainly." A pause. "He didn't kill her."
The sentence is simple and factual and carries underneath it something that isn't simple or factual, the specific weight of a thing that matters to her beyond the evidentiary.
"I know," I say. "There's something else." I tell her about the sent message. I read it to her verbatim. I hear her breathing change on the third ring the way it changed when she read the letter, the barely perceptible shift of a person absorbing something that rearranges other things.
She doesn't speak for a moment.
"21:34," she says finally.
"Yes."
"He had twenty-six minutes. Between sending that message and the estimated time of death." She pauses. "Shinjuku to the apartment from wherever he was is fifteen minutes minimum."
"He was close. He almost made it."
Another silence. Longer.
"Rei-san."
"I'm here."
"Nishida said to tell you before midnight. That it would matter for how you read Minami."
"He's right." Her voice is even, controlled, the professional surface intact. But I've been listening to the space beneath that surface all day and I can hear what the surface is working against. "Thank you for telling me."
She ends the call.
I put the phone down.
Outside the garden is fully dark now, the persimmon tree invisible except for the faint orange of the fruit catching the light from the window. Somewhere in Yanaka ward, less than a kilometer from where I'm sitting, a cemetery holds a grave with the name Saitō on it.
In three hours I'm going to stand at that grave.
I'm going to stand there in a body that walked back into a trap for the right reason and didn't survive it and somehow kept going anyway, and I'm going to meet a person who has spent a decade building evidence against a structure powerful enough to kill journalists and frame dead men, and I'm going to find out if the name Minami belongs to someone I should trust.
I look at the persimmon tree.
I think about a man I never met who is somehow the shape of everything I'm navigating.
I think about what Nishida said. That's not what I expected.
Neither did I.
Neither, I think, did Saitō.
