The Hunt for the London Guide

Summary:

In a world where Sentinels are humanity’s genetically heightened protectors and Guides are the empaths who balance them, James Bond, 007, stands as the Alpha Sentinel of London, powerful, disciplined, and dangerously unanchored after years without a bond. His perfect counterbalance has been beside him all along: Q, the brilliant but reclusive Quartermaster, whose sarcasm conceals his true nature as Edmund Montgomery, a Neural Architect-class Guide capable of harmonizing an entire city’s psionic network.

Years ago, Edmund survived a forced-bond attempt by Raoul Silva, a rogue Sentinel serving SPECTRE, leaving him scarred and in hiding. When Silva resurfaces to hunt the mysterious “London Guide,” Bond and Q are thrust into an alliance that tests every boundary of loyalty and control. Together, they must face Silva, stop a psionic war that threatens to consume the city, and confront what it truly means to trust.

Notes:

Author’s Note 1: Inspired by the story “Moonhunt” by Dolimir (The Sentinel fandom, Jim/Blair pairing. You can read the story here: https://archiveofourown.org/works/208771

Author's Note 2: There is attempted force bonding and trauma recovery in this story. While not explicit, it fits best under the non-con warning. The rating may change to Explicit based on how explicit the sexytimes scenes become (honestly, I write them last because it takes me forever to be creative LOL).

Author’s Note 3: I like to use Edmund Montgomery as Q’s “real” name in the majority of my Q fanfics!

Chapter 1: Ghost Frequency

Chapter Text

The lower levels of the Secret Intelligence Service never truly slept.

The Directorate for Research and Applied Technologies, affectionately known as Q-Branch, named for his predecessor, the longest serving Quartermaster, Major Geoffrey Boothroyd, stretched beneath the South Bank like a buried hive, all reinforced glass and steel and restless energy. The main floor alone was a map of genius and chaos: drone bays humming at one end, armor-fabrication printers exhaling the smell of hot polymer at the other. The air tasted faintly of ozone and solder, as if thunderclouds were trapped in the ventilation system.

From the mezzanine, Edmund Montgomery watched the organism he had built at work.

When he had taken control of Q-Branch, there had been twelve disjointed divisions, each brilliant and each chaotic, but none speaking the same language. Weapons engineers dismissed coders; field medics ignored data scientists; the vehicle specialists viewed every prototype as an excuse to violate the laws of physics and most of the health and safety code. Q-Branch had produced miracles, yes, but only by pure luck.

“This is madness,” he complained to Tanner over drinks at a nearby pub. “How did Boothroyd get anything done?” 

“He was a bit of an empire builder. I remember hearing a story about him during the early years of Q-Branch. Some Minister wanted to bring Boothroyd to heel and Boothroyd said, very calmly, that he didn’t appreciate bureaucratic interference and if he didn’t leave them alone, he’d put a car bomb in one of his vehicles.” 

“Bloody hell.” 

“Q-Branch truly is the domain of the Quartermaster. M promoted you so that you’d bring change and innovation to the Directorate.” 

It had taken him nearly two years of sleepless nights, relentless analysis, and more than a few political battles with the old guard. Edmund began by mapping the Directorate’s fractured anatomy: twelve separate funding streams, competing contracts, redundant logistics, and staff who’d rather sabotage each other’s projects than collaborate. He tore it down to its framework, then rebuilt it from the ground up, structure first, loyalty second, efficiency last.

He interviewed all one hundred and thirty-three members of the Directorate himself, cataloguing every strength, every eccentricity, and every frustration. He learned who thrived under pressure and who needed quiet to think, who designed brilliance in theory and who could build it blindfolded at three in the morning. Each person, from administrative staff to senior scientist, was reassigned with surgical precision to where they would matter most, not to the bureaucracy, but to the field.

Five streamlined divisions answered to him now: Weapons Design and Field Adaptation, where ex-military engineers argued cheerfully about recoil algorithms while testing projectiles that could pierce reinforced steel at a thousand meters; Cyber Operations and Encryption, his personal temple of code, where the best hackers in Britain waged digital war against enemies who believed themselves untouchable; Vehicle Integration, the mechanics and aerodynamicists who considered gravity an obstacle and had once armored a speedboat to survive a missile strike; Experimental Systems Research, the polite name for things that occasionally exploded, staffed by scientists who treated safety protocols as interesting suggestions rather than rules; and Medical and Bio-Tech, some of the best medical professionals cataloguing every agent's genetic quirks, tracking everything from blood type, nanotech, to the mandated Sentinel-Guide psionic markers that had become standard protocol after the Istanbul Incident.

Rebuilding the Directorate wasn’t enough. Edmund attacked its budget next. MI6 leadership had long treated Q-Branch as a necessary extravagance, too costly to control, too valuable to eliminate. Edmund audited every ledger line, every off-the-books allocation, and rewrote the financial models himself. Every Great British Pound of taxpayer money, every untraceable fund hidden under “experimental expenditures,” was redirected to serve the agents in the field.

If an operative risked their life for King and Country, they deserved gear that didn’t fail, vehicles that didn’t falter, and medical tech that could rebuild them faster than they could bleed.

That philosophy became his mission statement: no agent left unsupported, no mission compromised by negligence.

Respect had not come easily. To the veterans of Q-Branch, Edmund had been an unproven outsider with too much smarts and not enough scars. To MI6 leadership, he was too young and too unwilling to play politics. But Edmund Montgomery was nothing if not relentless.

He worked longer hours than anyone, demanded excellence but rewarded it tenfold. When he made mistakes, he admitted them publicly. When someone else erred, he corrected quietly. Little by little, the sneers faded, replaced by the grudging acceptance that their new Quartermaster was not a bureaucrat but an architect: of systems, of people, of purpose.

Architect. The irony of that was something he kept close to his chest.

By the end of his third year as Q, the Directorate for Research and Applied Technologies was no longer twelve fractured laboratories fighting over funds. It was one living network, cohesive, self-correcting, and terrifyingly efficient.

Edmund allowed himself a rare moment of satisfaction. Every system below him, every console, every weapon, every byte of data, moved in harmony.

It had taken him three years, multiple panic attacks, and exactly one death threat from Accounting, but Q-Branch was no longer a facility. It was an extension of his mind. And now, it served its true purpose: to arm the agents who guarded their world, and the one Alpha Sentinel whose psionic power stretched over all of London.

He lived for this equilibrium. The hum of servers replaced music, the repetition replaced rest. Control meant calm, and calm was survival.

At 06:43 hours, the biometric servers finished their overnight sync.

Edmund moved towards the central console in his office, setting his mug of black coffee beside one of three large monitors. The coffee had gone cold long ago, but he drank it anyway, temperature was irrelevant when caffeine was the objective. Lines of data scrolled past, a litany of pulses, genomes, and sensory profiles, standard health updates for field agents. He skimmed out of habit, his mind already three steps ahead to the morning briefing, until one entry blinked ANOMALY DETECTED.

A few keystrokes summoned the source.

Genetic Psionic Marker ID: Montgomery, E. O. Classification Pending.

He frowned deeply; his genetic psionic marker shouldn’t be in the MI6 system, not in any system. It shouldn’t even exist at all. 

Underneath, the algorithm's verdict: GUIDE SIGNATURE CONFIRMED – Neural Architect-Class Probability: 94.7%

For an instant, everything in the lab seemed to sharpen, the hum of fluorescent lights became a physical vibration against his skin, the metallic tang in the air tasted like copper on his tongue, the distant thud of a lift door closing three corridors away echoed like a gunshot. He recognized the symptoms of adrenaline and forced his hands still against the console's edge. Another person might have panicked outwardly; Edmund's panic was surgical, precise, but contained behind layers of calculation.

His mind raced through implications like falling dominoes:

Classification. Testing. Observation. Assignment.

They would want to know why he'd hidden it. How long he'd known. What else he'd concealed.

They would want to bond him. Assign him. Control him.

They would ask about Hong Kong. About Tiago Rodrigues.  

Maggie's voice echoed in his memory, calm and pragmatic as always: "A Guide's power isn't in feeling everything. It's in knowing what not to feel. You build walls, not to shut the world out, but to give yourself space to think."

He'd spent five years building those walls, brick by careful brick, under her patient instruction. Five years learning to compress his empathic presence into something dense and quiet, a nuclear reactor wrapped in concrete rather than a bonfire visible for kilometers. Five years proving that he could function, could contribute, could be more than just a psionic resource to be catalogued and deployed.

All of it was about to unravel because of a routine biometric scan. 

All because of the Sentinel-Guide Genetic Identification Act.

The Istanbul Incident had become legendary long before Edmund joined MI6. It lived in the hush between sentences whenever the words unbonded Sentinel were spoken. The official reports called it a “psionic containment failure” during a joint operation, but Edmund had read the raw data before the files were redacted. He knew the truth. It wasn’t the containment that failed, it was control.

The mission parameters had been simple: a coordinated extraction of a North Korean courier carrying stolen genetic research from a NATO lab. Nothing about it should have changed the world. But among the team deployed to Istanbul was a man designated S-07A, a newly elevated Alpha Sentinel without a registered Guide. The records noted that his sensory capacity was “off the measurable scale,” which in bureaucratic language meant: we have no idea what he’s capable of.

When the firefight broke out in the Grand Bazaar, the courier detonated a prototype neural disruptor. The device was meant to jam sensory data for twenty meters. It hit the Alpha Sentinel in the open field instead.

For seven minutes, Istanbul became a living echo chamber. Every Sentinel within a fifty-kilometer radius received the same uncontrolled broadcast, the Alpha’s pain, panic, and rage. Some went feral, others shut down entirely. The sensory feedback loop shattered buildings and glass, crippled electronics, and killed twenty-seven people. Hundreds more were hospitalized for neural and psionic trauma.

By the time emergency Guide teams managed to neutralize the psionic resonance, the unnamed Alpha Sentinel had disappeared. The world governments agreed to bury the data. NATO called it a “localized chemical reaction.” MI6 called it “an unfortunate tragedy.”

But the scientific community called it something else entirely, the birth of the Sentinel-Guide Genetic Identification Act.

Every operative, soldier, and intelligence agent was now required to undergo screening. Blood type, neural resonance, sensory markers, empathic frequency. No one would ever again operate unbonded without clearance. And yet, like all laws born from panic, it carried a single, quiet exception.

Edmund hadn’t known, then, that he’d one day work with that exception.

He still remembered the first time he met the Alpha Sentinel of London, in room 34 of the National Gallery. The Sentinel was unreadable and radiating control like a magnetic field. Commander James Bond. 007.

The man whose psionic frequency could destabilize a city. The one who had taken down  Istanbul.

The Medical and Bio-Tech division had catalogued his data as a “Singular Frequency Anomaly.” It sounded clinical, but Edmund understood what it meant: Bond’s senses operated on a scale too vast for any Guide to withstand. His psionic field stretched across London’s neural lattice, touching every sensory signature within the city limits. Trying to bond him would have been like plugging a human nervous system into a lightning storm.

The MED-BIO doctors had written their findings in detached prose: No compatible Guide found. Recommend exception under Section 4-A of the Sentinel-Guide Identification Act. But the technicians whispered what everyone knew: He’s not exempt. He’s suppressed.

Bond’s control wasn’t balance, it was a constant throttling of his own psionic perception so he wouldn’t drown in it. The signs were there if one looked closely enough: the flicker of tension at high frequencies, the headaches he never admitted to, the way his gaze lingered a fraction too long before refocusing as if recalibrating reality.

Edmund had seen it the first time Bond walked past his workstation. The faint shimmer in the air when the man’s sensory field brushed against the room’s electrical signature. It wasn’t something most people would notice. But Edmund wasn’t most people.

He’d felt the faint psionic pressure, the strain of constant vigilance wrapped tight around a heartbeat that refused to yield. It reminded him of something he’d read once in the Istanbul reports, one single, redacted note buried deep in the file’s metadata:

Subject displays anomalous self-stabilization behavior despite neural fragmentation. Hypothesis: instinctive reliance on environmental resonance.

At the time, Edmund hadn’t understood what that meant. Later, he would. Bond didn’t need a Guide because the entire city served as one. The hum of traffic, the rhythm of rain, 10 million heartbeats, the vibration of the Underground, all of London was his stabilizer.

But even that was temporary.

Because cities changed. People broke. And unbonded Sentinels, no matter how strong, always reached a limit.

Edmund erased his genetic file with three keystrokes, copied the server path, and began building false audit logs before anyone would notice. His fingers moved with practiced efficiency, creating a digital trail that suggested routine maintenance rather than deliberate deletion. The backup servers would need handling too, he'd have to schedule a maintenance cycle that would corrupt just enough data to make the record unrecoverable without raising suspicion.

Less than twenty-four hours. That's all the time he'd have to go to ground and a secure location before the automated redundancy check flagged the discrepancy. He had prepared for this emergency, but it was also the blue moon and – 

A familiar voice interrupted the quiet efficiency. "Morning, Q."

Bond.

Edmund didn't turn immediately; he finished closing a program and schooled his expression into something resembling professional patience before facing him.

James Bond, 007, stood beside the elevator column with the casual posture of a man who'd never encountered a threat he couldn't charm or kill. The crisp line of his dark gray suit was at odds with the faint restlessness around him, that particular quality of alertness that marked all Sentinels. Everyone in the building knew he was a Sentinel, but only a few understood what that truly meant. To the staff he was simply 007, the man who walked through crossfire and came out immaculate, who could disarm a bomb with seconds to spare and still make his dinner reservation.

The Alpha Sentinel of London wasn't an official title, no one dared codify such things in writing, but MI6 and the Home Office both deferred to Bond instinctively. The European Sentinel-Guide Council bestowed the responsibility on an Alpha Sentinel. Every major city had a dominant Sentinel who balanced its sensory network, policing the others of their kind. London's pulse synced in time with Bond's psionic energy; the city trusted him the way a body trusted its heartbeat, unconsciously and absolutely.

Bond looked, as always, infuriatingly unruffled. His gaze drifted over the room, cataloguing details most people would miss: the new stabilizing harness hanging on the far wall, the faint smell of ozone from a faulty circuit in bay three, the caffeine level in Edmund's discarded mug. Sentinels processed the world in layers most mundanes couldn't imagine: scent, sound, texture, temperature, all feeding into a sensory tapestry that made them either perfect operatives or dangerous liabilities.

But balance required a Guide. Everyone knew that. What they didn't know was how desperately rare true-bond-potential Guides were, or what happened when Sentinels went too long without one. 

“Good morning, 007. Why are you here so early?” He stood, picking up his mug and walking down the staircase towards the large pantry on the other side of the labs. 

"Just checking on the upgrade to my Aston." Bond said, almost lazily, following Edmund with a predatory grace that never quite looked like walking.

"It’s in maintenance. Try not to crash this one before I've finished the schematics."

"I don't crash them, Q. You make them too fast."

"That's because you insist on driving them like a lunatic with a death wish and diplomatic immunity." Edmund allowed the faintest smile. "The vehicle team is still traumatized from extracting the last one from that Venetian canal. We had to file the recovery operation as a marine salvage exercise."

"The building was collapsing. I made a tactical decision."

"You made a theatrical exit. There's a difference." Edmund washed his mug in the sink and clicked the button on the electric kettle to boil the water. He opened the cabinet overhead to find his canister of Earl Grey tea. 

Bond's mouth quirked, blue eyes lighting with amusement. "The difference being that I survived."

"The difference being that I had to explain to Mallory why his budget now includes gondola repair costs."

Their exchanges drew a few smiles from the technicians pretending not to eavesdrop. Edmund permitted the familiarity; morale was high value currency in Q-Branch, and the legend of Bond's impossible exploits was part of the lab's folklore. 

Still, his mind was elsewhere, on the red-flagged genome now hidden behind six layers of encryption, on the twenty-four hours counting down, on the way Bond's presence seemed to fill more space than his physical form should occupy.

Bond shifted, a subtle narrowing of focus that Edmund had learned to recognize. Sentinels reacted to emotion before expression, their heightened senses catching the minute changes in heart rate, breathing, pheromone markers that betrayed what words concealed. Edmund knew the agent could sense the change in his heartbeat, the slight acceleration, the tension in his shoulders, the faint bitter scent of adrenaline cutting through the coffee and ozone.

"You all right, Q?" Bond said, his tone was light but the eyes were sharp, predator-bright, the blue of them almost unsettling in their intensity. "You seem..."

Compromised. Exposed. Panicked.

"I’m fine," Edmund said, his voice perfectly level. "Merely caffeinated beyond salvation. I've been here since four."

"That explains the third mug. Though it doesn't explain why you were deleting files at –" he glanced at his watch without breaking eye contact, "-- oh-six-forty-five on a Tuesday morning."

Edmund's heart stopped, then resumed at exactly the same controlled pace. Of course Bond had noticed. Sentinels always noticed.

"Routine maintenance," Edmund said, smoothly. "The biometric system has been flagging false positives. Ghost frequency signatures in the coding architecture." He met Bond's gaze without flinching, a skill he'd perfected over years of lying to people trained to detect lies. "I'm cleaning the databases before M's morning briefing. He's already irritated about the budget. I'd prefer not to add 'faulty AI' to his list of grievances."

For a long moment, Bond simply looked at him. Edmund could feel the weight of that attention like pressure against his skin, as if Bond's senses were cataloguing every microexpression, every shallow breath, every beat of his traitorous heart.

Then Bond smiled, that easy, charming smile that had disarmed enemies and seduced assets across three continents. 

"Well. Can't have M irritated. He's terrifying enough when he's pleased."

"A fact you seem to forget every time you improvise in the field."

"I don't improvise. I adapt."

"You destroyed a priceless historical landmark."

"It was mostly destroyed already. I simply accelerated the inevitable."

"The inevitable being your own dramatic tendencies."

Bond laughed, the sound warm and genuine, and Edmund felt something in his chest tighten inexplicably with pleasure. 

"Careful, Q. People might think you actually worry about me."

"I worry about my equipment. You simply happen to be attached to it most of the time."

"How flattering."

"I don't do flattery. I do functional design and cost-benefit analysis." Edmund turned back to the kettle, pouring the hot water into his mug. "Now, if you'll excuse me, I have seventeen requisition orders to fulfill, a meeting with the Joint Intelligence Committee, and your latest disaster to troubleshoot before lunch."

"What disaster?"

"The exploding pen. I never should’ve made one.” 

"Ah." Bond had the grace to look slightly sheepish. "In my defense, the instructions said 'twist clockwise.'"

"They said 'twist clockwise gently.' The word 'gently' was in bold. Underlined. With a warning label."

"I was under fire at the time. Nuance seemed less important than immediate explosive yield."

Edmund pinched the bridge of his nose. "Get out of my lab, 007."

"That's the gratitude I get for field testing your devices?"

"The gratitude you get is not being charged for the replacements. Now leave. Some of us have actual work to do."

Bond studied him for another second, and Edmund felt that predatory focus again, assessing, measuring, noting the tension Edmund couldn't quite hide. Then Bond smiled again, softer this time, almost fond.

"Try not to overheat your processors, Q," he said, quietly.

When he left, the space seemed to exhale. Edmund closed his eyes and counted the seconds until the echo of Bond's presence faded from the room. He felt...disoriented, as though part of the environment had gone silent. The ambient hum of the lab seemed flatter somehow, less textured, as if someone had turned down the volume on reality itself.

He recognized the sensation. He'd felt it before, years ago in Hong Kong, when Tiago had stepped too close and Edmund's untrained empathic senses had reached out instinctively, desperately seeking the balance that Sentinels and Guides were meant to provide each other.

It had nearly destroyed him then. Maggie Chau had pieced him back together, teaching him that survival meant isolation, that safety required walls. He wouldn't, couldn't, let those walls crumble now.

Edmund opened his eyes and got back to work; pity that it would be for the last time.

*** 

Evening descended quickly and Edmund noted his staff departing throughout the night. The teams trickled out in waves, first the junior technicians at seventeen-hundred hours, then the senior engineers by eighteen-thirty, finally the night-shift skeleton crew settling into their routine by nineteen-hundred. Edmund stayed, as he always did, surrounded by the soft machinery hum that had always been his refuge.

The lab looked different in the evening, softer somehow, the harsh fluorescents replaced by ambient blue light from monitors and the warm glow of diagnostic panels. Edmund had always preferred it this way: the quiet, the solitude, the absence of eyes that might notice too much.

He reopened the secure console, fingers moving across the keyboard with practiced precision. His fake audit logs looked perfect, a masterpiece of digital misdirection that would satisfy even the most suspicious review. But he knew perfection wouldn't be enough. The genetic division kept redundant backups across three separate server farms, each with its own automated verification system. Sooner or later, someone would notice the blank entry. Sooner or later, someone would ask questions.

Why didn't you report the classification, Mr. Montgomery?

How long have you known what you are?

What else are you hiding?

Tell us about Hong Kong. Tell us about Tiago. Tell us why you ran.

Did you help Raoul Silva infiltrate MI6? 

His mobile buzzed, and Edmund glanced at the screen: a message from an unlisted number, the encryption signature one only Maggie Chau used.

Saw the news about the biometric upgrades. Be careful, darling. The walls we built were meant to keep you safe, not comfortable. Don't mistake one for the other.

Edmund stared at the message for a long moment. Maggie always knew, somehow, across continents and encrypted channels, she sensed when he was in danger. It was a Guide thing, she'd explained once. Those who'd survived trauma together carried echoes of each other, faint psionic fingerprints that never quite faded.

He typed a reply: I'm handling it.

Her response came immediately: That's what worries me. Handling and surviving aren't the same thing. Remember what I taught you: shields first, but know when to lower them. Some battles require trust.

Trust. The word sat in his chest like a stone.

Edmund deleted the conversation and removed his MI6 security badge, laying it neatly beside the keyboard. Every action was deliberate, methodical, the ritual of a man who had learned long ago that preparation was the only defense against chaos. He copied his encrypted files to a micro-drive no larger than his thumbnail, a custom design that would fry itself into slag if anyone tried to access it without his biometric signature. He erased traces of his access with a program that would overwrite the deleted data seventeen times, rendering it irrecoverable even by MI6's best forensic specialists.

Finally, he slipped the drive into the inner pocket of his coat, the one he'd reinforced with a Faraday weave to block tracking signals.

When he finally looked up, the reflection in the glass caught him off guard: a thin man in shirtsleeves, eyes shadowed with exhaustion, surrounded by the living machinery of the empire he'd built; the whole vast organism breathing in synchrony with his own desperate pulse.

He wondered what Bond would sense if he were here now, the panic beneath the calm, the electrical hum that had begun thrumming in Edmund's veins ever since the words Neural Architect-class Guide appeared on that screen, the way his empathic shields were already starting to fracture under the weight of proximity to an unbonded Alpha Sentinel.

He wondered if Bond had felt it too, that moment of recognition when their eyes met in the pantry. That pull, that resonance, that terrifying sense of fit that made Edmund's carefully constructed isolation feel suddenly, devastatingly fragile.

He shut the thought down with the same ruthless efficiency he applied to everything. Curiosity was dangerous; connection worse. Maggie had taught him that lesson after Tiago, and he wouldn't forget it again.

"You build walls not to shut the world out, but to give yourself space to think," she'd said during one of their early sessions in Hong Kong, her fingers steady on his wrist as she guided him through the breathing exercises. "But remember, Edmund, walls that never open become prisons. Know there is a difference."

At the time, fresh from Tiago's assault, he'd only heard the first part. Now, standing in the near empty lab with London glowing beyond the walls, he wondered if he'd built a sanctuary or a cell.

Edmund powered down the console with a series of commands that would trigger a routine maintenance cycle, nothing suspicious, nothing that would raise alarms. Hidden in the routine was just two lines of code that would corrupt anything related to him. He turned out the lights one section at a time, watching his empire sink into darkness.

Behind him, Q-Branch continued to breathe, steady, efficient, and unaware that its Quartermaster was already becoming a ghost.

He walked into the corridor without looking back.

The rain had intensified by the time he reached the exit, a London downpour that turned the streets into rivers of reflected light. Edmund stood in the doorway for a moment, coat collar turned up against the weather, watching the city that was about to lose him.

Somewhere out there, Bond was sleeping, or working, or seducing someone in a way that would later serve MI6's interests. Somewhere out there, Tiago was alive, enhanced, hunting, waiting.

Somewhere out there, the Moonhunt was coming.

Edmund stepped into the rain and disappeared.
