Singapore hadn't changed since Murphy's last visit. The same gleaming towers, the same manicured streets, the same humid air that wrapped around you like a warm, wet blanket the moment you stepped off the plane. But three years ago, he had come here to deploy a patch on a server while Marcus Thorne watched from the shadows. Now he was here to find a woman who had spent two decades hiding from everything his father had built.
Chidi met them at Changi Airport, his face breaking into a broad smile when he saw Murphy. The former Nigerian soldier had aged in the intervening years—more grey in his hair, deeper lines around his eyes—but his handshake was still bone-crushing and his eyes still missed nothing.
"Mr. Blake. Or should I say, Champions League winner. My daughter watched the final. She said it was the most beautiful thing she had ever seen. I told her she should see her mother's jollof rice. She disagreed."
"Thank you, Chidi. How's the family?"
"Growing. My son is at university now, studying engineering. He wants to build things. I told him building is good, but protecting what you build is better." He turned to Marcus. "Dr. Okonkwo. Your father would be proud. The work you did on the cascade—I don't understand it, but I know it matters."
Marcus nodded, visibly moved. "Thank you. I wish he could have seen it."
"He sees. Trust me." Chidi led them to a waiting vehicle—the same battered Toyota Hilux, somehow still running, still bulletproof, still carrying the scars of a hundred operations. "I have a team of four waiting at the safe house. Former colleagues, all of them. They don't ask questions. They don't keep records. They just do what needs to be done."
The safe house was in a nondescript apartment block in the Geylang district, far from the glass towers of the financial center. Inside, it was sparse but functional—a central room with monitors and communications equipment, a small kitchen, two bedrooms. The four men Chidi had promised were already there, cleaning weapons and speaking in low voices. They looked up when Murphy entered, assessed him in a single glance, and returned to their work.
"Dr. Vance's office is in the Marina Bay financial district," Chidi said, spreading a map across the table. "She operates under the name Cross Cybersecurity. Very legitimate. Very above board. Government contracts, corporate clients, even some academic work with the National University. She's been here six months and already she's one of the most respected people in her field."
"Six months," Murphy said. "She must have been planning this for years. Building credentials. Establishing a reputation. No one questions a respected cybersecurity expert asking questions about aviation networks. It's literally her job."
"Exactly. Which makes her very difficult to approach. She has diplomatic connections, political protection, and likely a very good understanding of how to make unwanted visitors disappear."
"I'm not planning to disappear." Murphy studied the map. "What's her daily routine?"
"She arrives at her office at 8 a.m. precisely. Works until noon. Takes lunch at an outdoor café in the financial center—always the same café, always the same table. Returns to her office at 1 p.m. Leaves at 7 p.m. She has a driver, a personal assistant, and what appears to be a private security detail of three men. Former military, by the look of them. Professional."
"They know she's a target?"
"They know she's someone. No one hires that kind of security for a cybersecurity consultancy."
Murphy considered the options. A direct approach at her office was impossible—too many witnesses, too much security, too high a chance of creating an international incident. The café might work, but again, the security detail would be present, and Vance herself was likely trained to detect and evade threats.
"What about her home?"
"Private apartment in the Tanglin district. Extremely secure. Gated community, private security, the works. We could breach it, but not quietly."
"Then we don't breach it. We make her come to us."
Marcus looked up from his laptop. "How?"
"She's been probing Skynet for six months. She's getting closer to the Foundation Stone. What if we give her what she's looking for? Or rather, what if we make her think we've given her what she's looking for?"
"A trap."
"A conversation. She's a disciple of Philip Voss. She's spent twenty-three years searching for something my father hid in the deepest layer of Skynet's architecture. I'm Henry Blake's son. If I reach out, she'll respond. Curiosity alone would compel her."
Chidi shook his head. "Too dangerous. She'll bring her security. She'll control the location. You'll be walking into her hands."
"No." Murphy smiled, an expression that didn't reach his eyes. "She'll think I'm walking into her hands. But she doesn't know about the seventeen servers. She doesn't know about the Carthage Protocol. She doesn't know that I've been fighting this war since the day my father died. She thinks I'm a football club owner who inherited a technology company. She has no idea what I've become."

The message was sent through channels that Thorne had provided—an old Consortium communication protocol that Isadora Vance would recognize but that no one else would. Two lines of text:
*I have what you're looking for. Meet me where the river meets the sea. Come alone. — M.B.*
The response came within the hour:
*I know who you are, Henry Blake's son. I've been expecting you. Tomorrow, 7 p.m., East Coast Park. I'll find you.*
"She's confident," Marcus said, reading the message over Murphy's shoulder. "Too confident. She's setting a trap."
"Of course she is. But she's also curious. She could have refused. She could have ignored the message. Instead, she agreed to meet. She wants to see me. She wants to understand."
"Understand what?"
"Whether I'm my father's son, or just a boy who inherited his crown."

East Coast Park stretched along Singapore's southeastern shoreline, a long ribbon of sand and palm trees and cycling paths where families picnicked on weekends. On a Tuesday evening, it was mostly empty—a few joggers, a few fishermen, the distant hum of container ships making their way toward the port. The "river" in Murphy's message was a small canal that emptied into the sea near the park's eastern edge, a place where fresh water and salt water mingled in an endless, churning dance.
Murphy arrived an hour early, accompanied by Chidi and two of his men. The others were positioned at various points along the park, disguised as joggers and fishermen and people walking their dogs. Marcus was in a van a kilometer away, monitoring communications and feeding Murphy information through a nearly invisible earpiece.
"She's already here," Marcus said. "Arrived thirty minutes ago. She's walking along the beach, alone. No visible security."
"There's no such thing as no security. Not with a woman like her."
"She's very good at hiding them."
Murphy walked toward the meeting point—a small wooden pier that jutted out into the channel. The sun was setting over the Straits of Singapore, painting the water in shades of orange and gold. And at the end of the pier, her silver hair catching the dying light, stood Isadora Vance.
She was smaller than her photograph suggested, and older. The sharp features had softened with age, though the eyes remained the same—pale blue, penetrating, the eyes of someone who had spent decades looking for hidden things. She wore a simple linen dress and sandals, as if she were on holiday, as if this were a casual encounter rather than a confrontation twenty-three years in the making.
"Mr. Blake." Her voice was low and measured, with the faintest trace of a Welsh accent. "You look like your father. The eyes, mostly. He had the same way of looking at people—as if he were seeing through them to something beyond."
"You knew my father."
"I knew him very well. We were enemies, I suppose, in the way that people who share a purpose are enemies. He wanted to close the back door. I wanted it to remain open. Neither of us was wrong, exactly. We just had different visions of what the world should be."
"Philip Voss's vision."
Her expression didn't change, but something flickered behind her eyes. "You've been reading your father's journals. And Thorne's archives, I imagine. You know about Philip. You know what your father did to him."
"I know my father did what he had to do to protect the world from a man who had lost his mind."
"Is that what you think? That Philip had lost his mind?" She shook her head slowly. "Philip Voss was the sanest man I ever met. He understood something that your father never grasped. The aviation network is not a tool. It's a nervous system. It connects everything. Governments, economies, militaries, refugee flows, disaster response, food supply chains, pharmaceutical distribution. Everything that matters moves through the sky or depends on things that do. To leave such a system in the hands of politicians and markets and democratic chaos—that's not freedom. That's negligence."
"So you wanted to control it."
"We wanted to steward it. To protect it from the worst impulses of humanity. Wars have been prevented because the Consortium had access to diplomatic communications. Famines have been averted because we could track food shipments and redirect them before anyone knew there was a crisis. The back door was never about power for its own sake. It was about responsibility."
Murphy stared at her. The sun was almost gone now, the sky shifting from orange to purple to the deep blue of tropical evening. "The back door is closed," he said. "Permanently. Whatever good you think it did, it's over."
"I know. I felt it, you know. When the cascade completed. It was like hearing a familiar sound suddenly stop—a hum you didn't realize you'd been hearing until it was gone." She turned to face him fully. "But you didn't come here to discuss the past. Your message said you had what I'm looking for."
"The Foundation Stone."
Her eyes widened, just slightly, before she regained control. "You've found it."
"I've known where it is since the day the cascade completed. My father hid it in the one place he knew you would never look. The one place you couldn't access without destroying everything you claimed to be trying to protect."
"Where?"
Murphy smiled. "I'll tell you. But first, I want to understand. The kill switch—Excalibur. What do you intend to do with it?"
Isadora Vance was silent for a long moment. The waves lapped against the pier. The first stars were beginning to appear in the darkening sky.
"Excalibur is not a weapon," she said finally. "It's a deterrent. The back door was about information. Excalibur is about survival. If the aviation network were ever compromised—truly compromised, by a state actor or a terrorist organization or some other force we can't predict—Excalibur would allow us to shut it down before billions of lives were affected. A controlled shutdown, followed by a controlled restart. An insurance policy against catastrophe."
"And who decides what counts as a catastrophe? You?"
"Philip believed the Consortium should make that decision. A council of experts, insulated from political pressure, guided by wisdom rather than expediency. I still believe that."
"My father believed no one should have that power."
"Your father was an idealist. A good man. The best man, in many ways. But he was wrong about this." She turned to face him, and her eyes were no longer cold. They were almost pleading. "Mr. Blake, I have spent twenty-three years trying to find the Foundation Stone. Not because I want to destroy anything. Because I want to protect it. The probes you detected—they weren't an attack. They were reconnaissance. I needed to know if anyone else was searching for Excalibur. And they are. There are forces in this world—new players, groups that didn't exist when Philip and your father were fighting their war—that want that kill switch. Not as a deterrent. As a weapon. If they find it before I do, the consequences will be catastrophic."
Murphy studied her face. She was telling the truth—or at least a version of it. The question was how much she was leaving out.
"Who are these new players?"
"I don't know. Not yet. But I've been tracking them, the same way I've been tracking your network. They're sophisticated. Well-funded. They have access to technologies that even the Consortium at its height didn't possess. And they're getting closer."
"Closer to the Foundation Stone?"
"Closer to understanding what Excalibur is. Once they understand, they'll stop at nothing to find it."
The pier creaked beneath them. A fishing boat chugged past in the channel, its lights reflecting on the dark water. Murphy thought about his father's warning: *She is not motivated by power or greed or ideology. She is motivated by something older. Something colder.*
"I'll make you a deal," he said. "You stop probing my network. You share everything you know about these new players. And when I'm satisfied that you're telling the truth—all of the truth—I'll take you to the Foundation Stone."
Her eyes narrowed. "Why should I trust you?"
"Because you've spent your entire adult life searching for something my father hid. You've come closer than anyone. But you'll never find it without me. And without you, I may not be able to stop whoever else is looking for it. We need each other, Dr. Vance. The question is whether you can accept that."
The silence stretched between them like a wire pulled taut. Then Isadora Vance did something Murphy had not expected.
She laughed.
"You are your father's son. He made me almost exactly the same offer, thirty years ago. I refused. I thought I could find the Foundation Stone on my own. I was wrong." She extended her hand. "I won't make the same mistake twice."
Murphy shook it. Her grip was strong, the skin cool and dry.
"Tell me about the new players," he said. "Everything."
