Monday morning arrived grey and quiet at seven o'clock, blue light filtering through the high windows of the robotics lab. On the bench, the Arm looked different now, its sleek factory standard casing gone, replaced by the rugged, slightly rusted titanium valve from the scrapyard, bolted onto the wrist assembly. It looked like a cyborg stitched together from two separate worlds, half high tech, half Mad Max salvage yard.
Emily was tightening the final bolt, still wearing Sebastian's white dress shirt, sleeves rolled up, the grey joggers hanging loose at her waist. She looked exhausted but wired, the particular electric tiredness of a person who had not slept and did not especially care.
Sebastian sat on a stool nearby, drinking stale coffee, back in his formal clothes now, the night's adventure folded away somewhere beneath his usual composure.
"Hydraulic pressure stable at three thousand PSI," Emily said, voice raspy, looking at him. "Ready for the firmware patch?"
"Upload it."
She typed. The progress bar filled. UPLOAD COMPLETE.
The arm twitched, a smooth, silent motion. The jitter was gone entirely.
"No latency," Sebastian said, nodding.
Emily leaned back, stretching her arms, her spine cracking audibly.
"We did it," she said.
Sebastian looked at the ugly, Frankenstein looking robot arm, then at Emily, drowning in his shirt, hair a disaster, eyes shining with something that looked a great deal like triumph.
"We built a monster, Miss Baker," he said. "Now let's hope it behaves in public."
❦
By nine, the seminar room had filled with tension, Professor Henderson sitting at the main desk with three other skeptical faculty members beside him, students watching from the back, whispering among themselves. Emily stood by the robot, changed back into her own jeans and hoodie, looking like a student again rather than whatever she had been at four in the morning in a stranger's bathrobe. Sebastian leaned silently against the back wall, observing.
"You are asking for permission to proceed to the dissertation phase, Miss Baker," Henderson said, checking his watch. "But your hardware looks like it was salvaged from a skip."
"Function over form, Professor," Emily said, chin up.
"Proceed. Standard dexterity protocol."
Emily nodded. She placed a raw egg on a stand and typed a command.
The arm moved, fast, far faster than any standard safety protocol allowed. The class gasped. Henderson's voice rose in alarm. "Too fast! You'll crush it!"
Emily didn't slow it down.
The fingers halted one millimeter from the shell. Instant deceleration. The titanium valve released pressure instantly, and gently, delicately, the cold metal fingers closed around the egg. It lifted. It moved across the table. It placed itself gently into an egg cup.
Click. Release. The egg was perfect. Unbroken.
Silence.
Henderson leaned forward, picked up the egg, checked it for cracks. None.
"Zero latency," he said, grudgingly, looking at Emily. "How did you bypass the hydraulic lag?"
"We didn't. We replaced the valve with a high pressure aviation actuator."
"Aviation? That's... unconventional." A beat. "But effective." He scribbled on his form. "Proposal approved. You may begin your dissertation."
The students at the back erupted into applause. James gave her a thumbs up. Emily exhaled, a wave of relief washing over her, and looked across the room. Sebastian was still leaning against the wall. He didn't clap. He simply caught her eye and gave a single, subtle nod.
❦
"Unconventional," Sebastian said, falling into step beside her as they walked out into the corridor. "Coming from Henderson, that is high praise."
"We pulled it off," Emily said, grinning. "The scrapyard gamble worked."
"The hardware worked. The code was... adequate."
"'Adequate' from you is a Distinction anywhere else," she laughed. "I'll take it."
They reached the exit. It was raining outside. Sebastian stopped, turning to her, his expression shifting into something more deliberate.
"The University Board is hosting the Cambridge Foundation Gala tomorrow night," he said. "At the Fitzwilliam Museum."
Emily paused. She knew the event. It was for donors, aristocrats, and stars. Not students.
"I need to secure funding for the next phase of the Neural Network," he went on. "The key target is Lord Wentworth. He's old fashioned. He thinks AI is witchcraft." A beat. "He is the Henderson of the venture capital world."
He looked at her the way he looked at an unsolved equation, seeing a brilliant engineer who could translate innovation into a language an old fossil understood.
"I need someone who understands the tech to help me translate it for dinosaurs."
He pulled a thick cream envelope from his jacket pocket.
"Your invitation."
Emily took it. Admit One. Black Tie.
"You want me to go? As your translator?"
"As my associate." He glanced at her hoodie. "It's strictly black tie. I assume you can find something suitable? Or should I have my office send a catalogue from a rental agency? You'll need something formal."
Emily looked at the invitation, then at him. He thought she was Cinderella, apparently, in need of a fairy godmother and a pumpkin carriage. A mischievous glint appeared in her eyes.
"Don't worry, Professor," she said coolly. "I'll manage."
"Good. Don't be late."
He walked away toward the faculty parking lot. Emily watched him go, tapping the invitation against her palm. Translate for dinosaurs? She had been speaking that particular language since the day she was born.
❦
The Baker Manor foyer was a cathedral of silence that evening, Henry standing before a gilded mirror, fastening a platinum cufflink, looking impeccable in a bespoke tuxedo. Authoritative. Calm. A titan of industry, dressed for battle.
The heavy oak side door opened. Emily entered, looking like a wreck in her jeans, muddy sneakers, and hoodie, hair in a messy knot.
Henry watched her reflection in the mirror. He didn't turn around. He checked his pocket watch.
"I expected you home an hour ago, Emily."
"I'm sorry, Father," she said, breathless. "Traffic was a nightmare."
Henry turned slowly. He looked her up and down.
"The Foundation Gala is tonight. The car is waiting. I assumed you would be upstairs preparing."
Emily froze. She feigned exhaustion, slumping her shoulders.
"I can't go, Father. There's been a... critical failure at the lab. A system crash." She rubbed her face. "The Faculty needs every research student on deck to salvage the data. I have to go back."
Henry sighed, a quiet, heavy sound.
"Again. The machines." He walked toward her. "You are allowing your hobby to eclipse your duty, Emily. The Baker name is the anchor of this Foundation. Your absence will be noted. And commented upon."
"I know. I'm sorry. But I gave my word to my Professor. I can't leave the work unfinished."
Henry stopped in front of her. He straightened her hoodie string, a gesture of affection mixed with disapproval.
"Very well." A beat. "Go. Do your soldering. But try to remember that you are a Baker, not a mechanic."
He turned and walked out the main doors. The heavy thud of the door echoed through the foyer.
Emily stood still until she heard the crunch of the Bentley's tires on the gravel drive. Then she straightened up. The fatigue vanished. Her eyes sharpened. She sprinted up the grand staircase.
❦
Her dressing room was soft, warm, and scented with lavender, Margaret, sixty something, the family housekeeper, standing ready. On a mannequin hung The Dress: emerald green silk, vintage, high necked, backless, flowing like liquid water.
Emily burst in, stripping off the hoodie and jeans, kicking the muddy sneakers into a corner.
"He's gone," she said. "We have twenty minutes before the doors close."
Margaret moved efficiently, no questions, just action. Emily stepped into the silk. Margaret pulled the zip. It fit like a second skin.
"Your father will be in the VIP mezzanine, Emily," Margaret said. "If he sees you..."
"He won't. He'll be too busy lecturing the bankers about fiscal responsibility. I'll stick to the shadows."
Margaret opened a velvet box. The Diamonds. She fastened the necklace around Emily's neck, the stones cold, heavy, and blindingly bright.
"And all this subterfuge," Margaret said, "for the Professor?"
Emily put on diamond drop earrings, looking at her reflection. The transformation was terrifyingly complete.
"He thinks I'm a charity case, Margaret. He offered to send me a rental catalogue because he didn't think I owned a nice dress." She smirked. "I'm just... correcting his data."
Margaret handed her a pair of long silk gloves.
"Call the car service," Emily said, standing up. "Not the family driver. Get me a cab."
"It's already waiting."
Emily grabbed a small, beaded clutch and took a deep breath. She looked like a weapon wrapped in silk.
❦
Magnificence greeted her inside the Fitzwilliam Museum's grand hall, white marble, Greek statues, golden light. A string quartet played Mozart while waiters glided through the crowd with champagne trays, the assembled guests the elite of Cambridge and London, old aristocrats, tech investors, and academic royalty all mingling under one chandelier.
Sebastian stood near a marble pillar, slightly apart from the crowd, devastating in a black velvet tuxedo, sharp and modern, though his body language gave away a tension the suit couldn't hide. He gripped a tumbler of whisky, his eyes fixed on the main entrance. He checked his phone. No messages.
Outside, away from the paparazzi at the front, a black cab pulled up to the quiet West Gate. The door opened. A pair of silver stiletto heels touched the pavement, and Emily stepped out, a vision in emerald silk that clung to her frame like liquid water, cascading to the floor. Her hair was swept up in an intricate, aristocratic knot, revealing the long line of her neck, the diamonds glittering cold and blindingly bright at her throat.
She handed the driver a twenty pound note.
"Keep the change."
She turned to the guard at the door. He was about to ask for her ticket, but he saw the dress. He saw the diamonds. He saw the way she carried herself, and simply bowed, opening the door for her instead.
Emily walked in. Chin up. Shoulders back.
Sebastian was still watching the main doors, taking a nervous sip of his whisky, when a gloved hand touched his shoulder lightly.
"Professor."
Sebastian froze. He knew that voice, but the timbre was different. Richer. More confident.
He turned around slowly. He saw her.
He had expected the girl arriving in a cheap polyester rental. Instead, he was staring at a Queen.
His eyes traveled up the emerald silk hugging her waist, up to the diamonds dripping like ice around her throat, up to her face. Minimal makeup, red lips, eyes sparkling with a dangerous mix of amusement and challenge. As she shifted slightly, he saw the dress was completely backless, an expanse of pale, flawless skin framed by the green silk.
Sebastian's grip tightened on his glass. He opened his mouth. No sound came out.
"Close your mouth, Professor," Emily said, smirking. "You're staring."
Sebastian blinked, forcing his brain to reboot.
"I... I didn't see you come in," he said, voice rough.
"I took the side entrance. Less crowded."
Sebastian finally found his voice, though it was lower, huskier than usual. "The catalogue. I assume you didn't use it?"
Emily touched the diamond necklace, a casual, practiced gesture. "No. I found something in my mother's closet." She looked him in the eye. "I hope it's... adequate?"
Sebastian stepped closer, entering her personal space, the scent of her perfume hitting him full force.
"It is..." he said softly.
The tension between them was electric. Not appropriate for a faculty event. Raw. Emily felt a blush rising but suppressed it, leaning in to whisper.
"Good. Because you have incoming."
She nodded slightly to the left. "Three o'clock. The Jurassic Park exhibit is approaching."
Sebastian tore his eyes away from her. He looked. Lord Wentworth, seventies, was heading straight for them, looking grumpy. Sebastian stiffened, his armor going back up.
But Emily didn't flinch. She stepped forward, smiling, a dazzling, socialite smile sliding into place like a mask she'd worn her whole life.
❦
Away from the main dance floor, in a private alcove thick with the smell of forbidden cigars and aged brandy, Sebastian stood opposite Lord Wentworth, who looked like a bulldog poured into a tuxedo, holding a glass of port, utterly bored.
"The neural architecture is self evolving," Sebastian was saying. "It doesn't just process historical data, it anticipates market volatility with a latency of zero point five milliseconds."
"Stop," Wentworth said, waving a hand. "Just stop."
Sebastian froze, his jaw tightening.
"Self evolving. Volatility. You sound like the brochure for that crypto fund that lost me two million last quarter." He took a sip. "I don't do artificial intelligent, Professor. I invest in things I can control. Real estate. Shipping. Things that don't decide to evolve while I'm asleep."
"With all due respect, Lord Wentworth," Sebastian said, voice hardening, "shipping sinks. Real estate bubbles burst. My algorithm..."
"Your algorithm is witchcraft. And I don't buy witchcraft. I buy stability."
Wentworth turned away, dismissing him outright. Sebastian's grip on his glass tightened, his ego visibly bruised, and he looked about to say something sharp, something arrogant that would burn this bridge forever.
Emily stepped into the light.
"La stabilité est un luxe, Monsieur Wentworth," she said. "Mais dans ce marché, l'immobilité est la mort."
Wentworth stopped. The perfect Parisian French caught him off guard entirely. He turned back. He saw the emerald dress. The diamonds. The posture.
"And who might you be?" he said, raising an eyebrow.
"Emily," she said, smiling charmingly. "Professor Smith's associate."
She didn't offer a hand to shake. She waited for him to offer his. And he did.
"The Professor is a genius," she said, "but he sometimes forgets that not everyone speaks binary."
She glanced at Sebastian, signaling him to play along.
"He isn't selling you witchcraft, sir," she went on. "He is selling you a Risk Management Tool."
"Risk management? He said 'self evolving.'"
"Think of it as... a loyal butler." She stepped closer, lowering her voice confidentially. "It doesn't make decisions for you. It filters the noise so you can make the decision. It watches the door while you sleep. It's not about magic. It's about total control."
Wentworth swirled his port. The word control landed. He looked at Sebastian.
"Is that true, Smith? Or is she just spinning a pretty web?"
Sebastian realized, in that moment, exactly what she was doing. She was pivoting the pitch. He straightened up, regaining his confidence.
"She's right," he said. "You have absolute override power." A beat. "You mentioned losing two million last quarter? My system would have cut that loss within four seconds."
Wentworth looked at Sebastian. Then at Emily.
"A butler with a kill switch," he said, a gruff chuckle escaping him. "Now that... that I can sell to the Board."
He reached into his jacket and pulled out a heavy cream card, handing it to Emily, not Sebastian.
"Call my secretary. I want a demo. But no jargon. Speak English. Or French. Just not binary."
"Thank you, sir," Emily said, taking the card.
Wentworth lingered a moment, looking at Emily's face, the shape of her eyes, the set of her jaw.
"You have a sharp look about you, my dear. You remind me..."
Emily's eyes flickered. She raised her glass, smoothly interrupting.
"I hope that means I remind you of a good investment," she said, smiling charmingly. "To the partnership?"
Wentworth clinked his glass against hers. "To the partnership."
He reached out and took her gloved hand, bowing slightly, pressing a brief, old fashioned kiss to her knuckles.
"Enjoy the evening," he said, nodding, and turned to walk away, tapping his cane against the marble floor.
Sebastian let out a breath he'd been holding for five minutes. He turned to Emily, looking at her with a mix of relief and total bewilderment.
"'A loyal butler'? Really? I'm building a synthetic consciousness, and you compared it to Jeeves?"
"I got you the meeting, didn't I?" Emily said, sipping her champagne, and handed him the card.
Sebastian looked at the card, then at her. He shook his head, a small smile playing on his lips.
"Remind me never to play poker with you, Miss Baker."
❦
The orchestra swelled into a lush, sweeping waltz, the floor filling with spinning couples. Sebastian tucked Lord Wentworth's card into his breast pocket, buzzing with adrenaline.
"We just secured a Series A round in under five minutes," he said. "The Faculty record is six months."
Emily scanned the VIP balcony nervously.
"Liquidity achieved. Then we retreat, Professor. Rule number one of gambling: walk away while you're winning."
She started to turn, aiming for the exit. Sebastian stepped into her path, smoothly, deliberately.
"Wrong. Rule number one is: finish the performance."
He lowered his voice, nodding slightly toward the stairs. "Wentworth is watching."
Emily froze. She risked a glance upward. Wentworth was indeed lingering on the steps, looking down at them. If they bolted now, it would look suspicious.
"If we run now, he'll think we're con artists who just scored a hit."
Emily calculated. The exit was across the open foyer, a clear line of sight for her father on the balcony. The dance floor, however, was a sea of moving tuxedos and ballgowns. A forest of bodies. A perfect camouflage.
Sebastian extended his hand. A command, not a question.
"Dance with me."
"Fine. One dance. But keep to the perimeter. Do not drag me to the centre."
"Why?" he said, smirking. "Afraid the spotlight will blind you?"
"I just don't want to outshine your other donors. Let's go, Professor. Before I change my mind."
❦
They stepped onto the polished floor. Sebastian turned to face her, raising his left hand to take her right. Then his right hand moved to her waist.
His palm met the bare skin of her open back. He stopped. The fabric of the dress was cool silk, but her skin was hot and soft, and the contrast sent a visible jolt through him, his fingers twitching, instinctively splaying out to cover more of that warmth.
Emily felt his hesitation. She looked up, her breath hitching slightly. Their eyes locked. The noise of the party faded into a dull roar. The heat took over.
"Do you know the steps?" Sebastian said, voice lower, rougher now. "Or do I need to count?"
"Just try to keep up."
He pulled her in. Close.
They moved. It was effortless. They glided across the floor with a synchronized grace that usually takes years to perfect, Sebastian leading with strength, Emily following with fluid precision. As they spun, the centrifugal force pressed her body against his, her thigh brushing his, the scent of her filling his head entirely.
"You're a contradiction, Emily," he murmured near her ear, her chin resting near his shoulder.
"I adapt."
"No..." He tightened his grip on her bare back slightly. "In London, you were M. Wild, reckless. In the lab, you're the Mechanic. Grease under your fingernails, stubborn, but brilliant."
He spun her. The world blurred. He pulled her back in, nose to nose.
"But tonight... tonight is different. You didn't just put on a dress." He studied her face intently. "You walked in here like you own the place. The way you handled Wentworth, that wasn't charm. That was authority, which you can't learn in a lecture hall."
He was genuinely confused. The pieces of the puzzle didn't fit. The rich girl. The genius. The siren. Who was she?
"Which one is real?" he asked.
Emily looked at him. His eyes were dark, searching, stripped of their usual arrogance.
She felt the heat of his hand burning her back. She wanted to tell him. But she saw a silhouette in the distance. She smiled instead, a slow, enigmatic smile that didn't give an inch.
"A woman is like an algorithm, Professor," she whispered, leaning closer, her lips brushing his ear. "If you can see the source code, she loses her value."
Sebastian faltered. He missed a step, just a fraction.
She'd caught him. She'd played him.
He pulled back to look at her, a mix of frustration and intense desire on his face.
"You enjoy this," he said. "Keeping me in the dark."
"I'm just keeping you on your toes, Professor. You get bored so easily when you solve the puzzle."
She was right. And he hated it. But he loved it too. He spun her again, faster this time, possessive, claiming this moment even if he couldn't claim the truth.
The final note of the waltz hung in the air. Sebastian and Emily stopped moving, breathless, flushed, standing dangerously close. His hand lingered on her waist a second too long before sliding away.
Bzzt. Sebastian's phone vibrated in his breast pocket. He ignored it.
Bzzt. Long and insistent.
He frowned, pulling it out. The screen read: *URGENT.*
"Damn it," he said, torn. "It's the Swiss. They must have heard about Wentworth."
"Business calls, Professor," Emily said, stepping back. "You should take it."
Sebastian looked at her. He didn't want to break the connection, but he couldn't resist the deal either.
"I have to take this." He leaned in, voice low and commanding. "Go to the bar. Order a drink. We have unfinished business."
He gave her one last intense look, then turned and strode rapidly toward the quiet corridor, phone already at his ear.
Emily watched him go. She let out a long, shaky breath, then turned on her heel, aiming for the west exit.
❦
She walked fast, head down, trying to be invisible, rounding a massive marble pillar and, bump, walked straight into a wall of black tuxedo.
She looked up. Henry stood there, holding a crystal tumbler of whisky, looking entirely relaxed, as if he'd been waiting for her right there all along.
"Father," Emily said, freezing.
Henry took a slow sip of his drink, looking her up and down, the emerald silk, the diamonds, the flushed cheeks.
"I must admit, the Faculty's safety regulations have changed since my day." He gestured to her gown. "Is this the standard protective gear for fixing a system crash?"
Emily swallowed hard. There was no point in denying it.
"The crash was handled. I... I was drafted in for other duties."
"Evidently." A dry chuckle escaped him. "And the system failure you were attending to, does it know how to waltz?"
Emily flinched. He had seen everything. She straightened her spine. She was a Baker, after all. She wouldn't cower.
"I lied to you. I'm sorry. But Professor Smith needed help."
Henry's amusement faded slightly. His eyes sharpened. He glanced toward the corridor where Sebastian was pacing, shouting into his phone.
"Sebastian Smith?" He looked back at Emily. "You're playing a dangerous game, Emily. You think you're helping a genius. I see a wolf dancing with a lamb."
"He respects me, Father. He respects my mind."
"Does he?" Henry stepped closer, his voice dropping to a whisper. "Or does he respect the aura you're projecting tonight? The diamonds. The confidence." A beat. "The smell of old money. Men like him... they make acquisitions."
The words struck a nerve. Emily remembered Sebastian's confusion earlier. Which one is real? Had he been drawn to her? Or to the illusion of power she'd created?
"You don't know him," she said, defensive.
"And you do?" Henry finished his drink. "I know his type, baby. Have your fun. Play your role. But remember who you are. Don't let him tarnish it."
He patted her shoulder, a gesture that was affectionate but carried the weight of an order, and walked away, disappearing into the VIP crowd.
Emily stood alone by the pillar. She looked at the diamonds on her wrist. Then she looked at Sebastian in the distance, laughing triumphantly into his phone.
❦
Sebastian strode back from the corridor a few minutes later, glowing with victory, sliding his phone into his pocket. He walked up to the bar, scanning the stools.
The bar area was crowded with tuxedos and gowns, but the emerald green dress was nowhere to be seen.
He moved through the crowd. He checked the pillar where he'd left her. Empty. He checked the dance floor. He saw a flash of green, but it was just an elderly donor's wife.
His heart rate picked up. Not the adrenaline of the deal anymore. This was something else entirely. He ignored a banker trying to shake his hand.
"Don't play games, Baker," he muttered.
He scanned the room one last time.
❦
Sebastian burst out of the heavy wooden doors into the cool night air, the misty rain settling against his face. The street was empty. Just wet pavement reflecting the streetlamps.
He looked left. Nothing. He looked right. In the distance, the red taillights of a cab were fading into the fog, turning the corner onto Trumpington Street.
Sebastian stood there, water droplets settling onto his velvet tuxedo. He looked at his right hand, the hand that had held her waist just moments ago. He flexed his fingers, as if trying to grasp a ghost.
She was gone.
He reached into his pocket and pulled out Lord Wentworth's card. The deal was real. But for the first time in years, the victory felt hollow.
"Who are you?" he said quietly.
❦
Inside the Aston Martin, Sebastian slammed the door shut, the heavy thud sealing him inside the cockpit. He sat in the dark. The silence rang in his ears.
He gripped the steering wheel. His breathing was controlled, but ragged.
He reached into his breast pocket and pulled out his mobile, opening the keypad. His thumb moved, without looking, without hesitating.
0... 7... 8...
He typed the full eleven digits, a rhythm he had tapped out on his desk a hundred times in the last three months, but never once on a screen.
He stared at the green *CALL* button. His thumb hovered over it. It trembled, just a fraction.
Then a notification popped up at the top of the screen, an automated calendar reminder: TUESDAY 09:00, SUPERVISION: BAKER, E. (THESIS REVIEW).
The cold reality bucketed over him.
He remembered London. Waking up to an empty room. She hadn't just left, she had vanished. No note. No goodbye. His pride had told him to let it go. But God, for months, he had wanted nothing more than to hear her voice again. And fate, with its twisted sense of humour, had finally granted his wish, only for him to realize it was a curse.
He wasn't the man in the bar anymore. He was the Professor. She was his student. That line was drawn in concrete now. One step across it destroyed everything. Her degree. His reputation.
He looked at the number one last time. It was a temptation. A vulnerability. Then he pressed backspace.
One digit disappeared. Then another. Tap. Tap. Tap.
He deleted the entire string until the screen was blank again.
He locked the phone and tossed it onto the passenger seat.
He rubbed the back of his left hand with his thumb, right where the ink used to be. The skin was clean. But the ghost of the number still burned.
