Marcus had turned the kitchen table into an assembly line. Passport photos trimmed to specification. A Belgian travel document with the holographic seal that his Brussels contact had sourced from a retired customs official. Employment verification letters on company stationery that didn't belong to any real company. Financial records showing three years of steady deposits into an account that hadn't existed until yesterday morning.
"Jensen's cover name is Erik Lindqvist," Marcus said without looking up. He was checking the passport photo alignment against a template printed on card stock. "Swedish national, IT consultant, contract work for a Brussels-based firm. The firm exists, barely. Three employees and a website. My contact owns it specifically for this purpose."
"How many identities has he built through that firm?"
"Four in the last six years. None burned. The supporting documentation stands up to standard border checks. Not deep investigation, but Jensen doesn't need deep. He needs to get on a ferry to the continent and disappear into the EU for six months."
Cassius watched Marcus work. The man's hands were steady, his movements efficient. He'd done this enough times that the process was mechanical. But the speed was different. Marcus usually built exit packages over weeks, checking and rechecking each document against possible scrutiny. This one was being assembled in days, and the compression showed in the way Marcus didn't pause between steps, didn't double-back to verify, just moved forward because the timeline wouldn't let him move any other way.
The phone on the table buzzed. Not Marcus's phone. Not Lyra's. The burner Cassius kept for the backup contact channel, the one that only four people in the world had the number for.
He looked at the screen. Glasgow area code.
"Pryce," he said.
Marcus looked up.
Cassius answered. "Go."
"It's Osian." The voice was rough, Welsh accent thicker than usual, the sound of a man who'd been whispering for weeks and had forgotten how to speak at normal volume. "I need to tell you something about the Newcastle raid. Something I didn't mention when I made contact through the backup channel because I wasn't sure what I'd seen. I've had time to think about it. I'm sure now."
"Tell me."
"The team that hit the safe house, they came in fast. Professional. Standard Watcher tactics, the kind we've been trained to expect. Except one of them was carrying something. A device. Not a weapon, something else. About the size of a briefcase, matte black, with a screen on the front. He was holding it in front of him like a compass, and when they cleared the first floor, he stopped at the doorway to the room I'd been using. The room was empty. I was already on the back roof. But he stood there with this device and looked at the screen and said something to the team leader. I was close enough to hear it through the window."
"What did he say?"
"He said: 'Active signature, recent. Less than two hours. Single source, mid-range capability.' Then the team leader asked how recent, and the man with the device said: 'The trail is still warm. He's within a mile.'"
Cassius's grip on the phone tightened. "They were tracking your thread-signature."
"Not residual. Not a scar. I don't have a scar. I'm careful. They were tracking me. My thread-sight activity. I'd been using it that morning to monitor the street from the window, low-level passive sight, the kind I thought was undetectable." A pause. "It's not undetectable. Not anymore."
"What happened after?"
"I ran. Didn't use thread-sight again, didn't engage anything. Made it to a contact's flat in Gateshead, went dark. Took the train to Glasgow two days later. Haven't engaged thread-sight since." Another pause. "Cassius. The device was reading active thread-work. Not old scars. Not residual distortion. Live signatures. If they have that technology deployedā"
"Every Weaver who uses their sight is broadcasting."
"That's what I've been sitting with for three weeks. Yes."
Cassius looked at Marcus. Marcus had stopped working on the passport. His hands flat on the table, his attention on the phone call, reading what he could from Cassius's side of the conversation.
"Where are you now?" Cassius asked.
"Glasgow. A non-network contact's spare room. I haven't used thread-sight once since Newcastle. I've been living like a normal person for three weeks." A sound that might have been a laugh. "It's terrible."
"Stay dark. Don't engage any thread-work until I contact you again."
"I planned to stay dark regardless. But I thought you should know. Because if you're doing operational work right now, if you or your apprentice are using thread-sight anywhere near Soren's peopleā"
"I understand. Thank you, Osian."
He hung up. Marcus was already asking the question with his posture.
"Soren has real-time detection," Cassius said. "Not just residual scar-reading. Active thread-signature tracking. A portable device that can read live thread-work and estimate range and capability."
Marcus took three seconds to process this. Three seconds was a long time for Marcus. "Lyra is in Cardiff."
"Lyra used thread-sight during her meeting with Nwachukwu." Cassius was already reaching for his own phone. "She engaged a passive scan to read the scar. If Soren's people have detection equipment deployed in South Wales, or if the range is wide enough to cover the Cardiff metro area from a fixed positionā"
"Call her."
He dialed. Two rings. Three.
"Cassius?"
"Have you used thread-sight since the Nwachukwu meeting?"
"No. I'm at the hotel. Why?"
"Don't use it. Don't engage any thread-work, not even passive scanning. Not until I tell you otherwise."
A beat. "What happened?"
"Soren's detection technology can track active thread-signatures. Not residual scars. Live usage. Pryce saw the device during the Newcastle raid. If anyone in Soren's organization was monitoring the Cardiff area when you assessed Nwachukwu's scar, they registered a Weaver presence."
Silence on Lyra's end. Then: "I was in her office for forty-five minutes. Thread-sight engaged for about twenty of those. Low-level passive, the kind Thorne called whisper-range." She paused. "How sensitive is this device?"
"Pryce said the operator described his passive street-level monitoring as a 'mid-range' signature detectable from at least a mile. Your assessment of a scar at close range would have been stronger than street-level monitoring. If they have a device in the Cardiff areaā"
"They might know I was there."
"They might know a Weaver was there. They wouldn't know who. But a Weaver appearing in the same city as one of their listed witnesses, within hours of Soren accelerating the committee dateā"
"Would be hard to write off as coincidence." Lyra's voice had gone clipped. The fragments of longer sentences breaking apart under stress, the speech pattern she fell into when the situation compressed. "The meeting tomorrow. With Nwachukwu. Seven in the morning. I can't read her scar without thread-sight. If I can't read the scar, I can't assess whether the repair is safe. If I can't assess, I can't offer the repair."
"I know."
"So what do I do? Show up blind?"
"Show up as a person having a conversation. No thread-work. No scanning. Talk to her, answer her questions, give her the information she needs to make a decision about the repair. If she agrees, we schedule the procedure for a time and place where we understand the detection risk."
"That could take days."
"We have eight."
The birthday fragment fired.
Three seconds. A child's face, round and smeared with chocolate, candles reflected in dark eyes, the smell of buttercream and wax, a room full of people singing. Not his birthday. Not his child. Not his memory. Three seconds of someone else's joy delivered with the disorienting precision of a dream inserted into waking life.
He was back. The kitchen. Marcus. The phone in his hand.
"Cassius?" Lyra's voice. He'd gone silent mid-conversation.
"I'm here. Fragment."
"How long?"
"Three seconds."
"That's shorter than the last ones."
"Shorter. More frequent." He moved past it the way he'd learned to move past them. Not by pushing through, by stepping around. "The detection technology changes everything. Every thread-manipulation we perform is potentially visible. The mirror-thread connection I used with the Grandmother two nights agoāthat's active thread-work. If Soren's equipment was in rangeā"
"Was it?"
"I don't know. I used it from Bermondsey. I don't know where his detection equipment is deployed or what its range is from a fixed position." He rubbed his eyes with his free hand. "We're operating in the dark on the parameters. Range. Sensitivity. Number of devices. Geographic deployment. We need that information before anyone does any thread-work."
"Jensen," Lyra said. "Jensen might know."
Marcus, who'd been listening to Cassius's side, spoke for the first time: "Jensen is an administrator. He might have seen budget allocations for the equipment without knowing the technical specifications. But the Silkworm documentation might reference it."
"The full 168-page document," Cassius said. "We read the operational sections. The technology specifications might be in an appendix or a classified annex that Jensen included."
Marcus was already moving toward the stack of documents on the side tableāthe printed pages from Jensen's USB drive, the full Silkworm report they'd been working through in sections as priorities dictated. "I'll check. If the technical specs aren't in the main document, I'll ask Jensen during the Wednesday handoff."
"Ask him before the handoff. Tonight, if possible. We can't wait until Wednesday to know whether the equipment can detect thread-work at the range we used for the Grandmother connection."
Marcus nodded. Picked up his phone. Left the room.
Cassius sat at the table with the passport materials and the burner phone and the quiet aftermath of three seconds spent in someone else's birthday party. The chocolate smell was gone. The singing was gone. What remained was the three-second gap in his awareness, the tiny hole in his present that the fragment had punched without asking permission.
He was getting used to them. That was the wrong response. Getting used to spontaneous consciousness displacement was like getting used to a leak in a ceiling: functional until the day the structure gave way. The fragments were eating his thread-tissue. Every firing consumed something. Every three-second interruption shortened the five years he'd calculated that morning.
Add it to the tab.
Marcus returned twelve minutes later. "Jensen confirms. Section nine of the Silkworm document, subsection C. 'Operational Detection Capabilities.' He says it's pages 134 through 141. He also says the technology is newer than the rest of the document. It was added during a revision three months ago, after Whitfield approved a discretionary budget for 'operational technology upgrades.'"
"What did Whitfield pay for?"
"Jensen's word: portable thread-activity sensors. Four units. Current deployment: two in London, one covering the northern corridor from Manchester to Newcastle, one mobile." Marcus sat back down at the table. Didn't pick up the passport work. "Four units. Two in London."
Two in London. The Bermondsey safe house was in London. The mirror-thread connection with the Grandmother had been performed in London. If one of those sensors had been within rangeā
"What's the detection range?"
"Jensen doesn't know the exact specifications. He said the budget documents referenced 'metropolitan-scale coverage,' which he interprets as roughly city-wide from a fixed position. But he's guessing. The technical specs are in the document. Pages 134 through 141."
Cassius stood. Went to the side table. Found the Silkworm printout, thumbed through to page 134. The section header read: *Operational Detection Capabilities: Thread-Activity Sensor Array (TASA), Mark II.*
He read. Marcus watched him read. The kitchen was quiet except for the sound of pages turning and the ambient noise of Bermondsey outside the blackout curtains.
Page 136: *Detection range (passive thread-sight): 800 meters to 2.4 kilometers, depending on operator capability and environmental interference. Detection range (active thread-manipulation): 4.8 to 12 kilometers, depending on manipulation magnitude.*
Active thread-manipulation. Twelve kilometers. The mirror-thread connection with the Grandmother was active manipulation. The Bermondsey safe house sat in southeast London. A sensor positioned anywhere in central London would have been within twelve kilometers.
He turned to page 138: *Current deployment: Unit 1, fixed position, Ministry of Defence Main Building, Whitehall. Unit 2, fixed position, Thames House. Unit 3, mobile, northern operations. Unit 4, mobile, reserve/training.*
Thames House. MI5 headquarters. Less than five kilometers from Bermondsey.
He put the document down.
"The sensor at Thames House is within range of this safe house," he said. "Active thread-manipulation is detectable at up to twelve kilometers. The mirror-thread connection I used two nights ago would have registered."
Marcus's hands went still on the table. The passport materials, the carefully constructed identity, the Brussels documents. All of it sitting on a kitchen table in a safe house that might already be marked.
"They know a Weaver performed active manipulation in southeast London two nights ago," Cassius said. "They don't know where exactly. They don't know who. But they have a directional reading and a timestamp."
"How long before they narrow the location?"
"Depends on the sensor's precision and whether they're actively investigating or passively logging. If they're logging, we have time. If Soren ordered immediate follow-up on any London detection eventsā"
"Then this safe house is compromised."
"Possibly."
Marcus looked at the passport work spread across the table. The exit package for Jensen. The identity of Erik Lindqvist, Swedish IT consultant, the documents that needed to be complete by Wednesday and handed over in Vauxhall. All of it dependent on a safe house that might have a Watcher team heading toward it.
"We need to move," Marcus said. "Tonight."
"We need to move. But we also need the Grandmother, and the only way to reach her is a mirror-thread connection that would light up every sensor in London."
The problem sat between them on the table, surrounded by another man's passport and the remains of tea that had gone cold hours ago.
Cassius looked at the blackout curtains. Somewhere beyond them, five kilometers northwest, a device in Thames House was recording thread-activity data. Somewhere in Cardiff, Lyra was sitting in a hotel room forbidden from using the one ability that made her useful. Somewhere in Glasgow, Osian Pryce was pretending to be ordinary.
And somewhere, Soren was reading the data and making plans of his own.
"We move tonight," Cassius said. "And we find a way to talk to the Grandmother that doesn't involve thread-work from inside a sensor's range."
"How?"
The question hung. Cassius didn't answer, because the answer required a calculation he hadn't finished, and the variables included his own remaining lifespan and a birthday party that wasn't his and four devices that could see him every time he opened his eyes to the threads.
