LA COUR NOIRE — THE HIDDEN CODE

9:16 P.M. — The Delcroix Estate, Private Study.

Rain whispered against the windows as four brothers gathered in the private study.

Damien, thirty-four, poured whiskey beside the drinks cabinet, his wedding ring catching the light. Nathan lounged in an armchair, his phone nearby, while Maxime, thirty, reviewed a report behind the desk.

Loïc, twenty-seven, sat opposite him in a black shirt and silver cufflinks, studying a line of figures.

Not because the numbers were complicated.

Because they were wrong.

"Someone has been moving money through one of our private accounts," Loïc announced.

Damien stopped pouring.

"How much?"

"Enough to make the attempt insulting. Not enough to make the person responsible particularly clever." Loïc turned a page. "The transfers were disguised as legitimate payments, routed through three accounts, and approved using an authorization code that should never have left our inner circle."

Nathan lowered his phone.

"So we have a leak."

"We have a problem," Maxime corrected. "We don't know whether it's a leak, a compromised account, or someone attempting to make us believe one exists."

"How comforting." Nathan glanced at Loïc. "And I suppose you've spent the last six hours staring at numbers until they confessed?"

"Five hours and forty minutes. The last twenty were spent wondering whether you'd developed the capacity to contribute something useful."

Nathan laughed.

"There's our little brother."

"Call me little again, and I'll make your next financial statement a fascinating work of fiction."

"Children," Damien muttered.

"You're the one who raised us to be difficult," Maxime observed.

"I raised you to be competent. The difficult part came naturally."

Loïc placed a photograph on the desk. It showed an ornate silver cigarette case encrusted with diamonds, an almost invisible engraving decorating one corner.

Maxime's expression sharpened. "Where did you get that?"

"An inventory of a private collection. The actual case is being displayed at tomorrow night's gala." Loïc tapped the engraving. "There's a concealed sequence here. It's a cipher connected to the financial authorization system we've been investigating."

Damien set down his glass.

"You're telling me someone put a key to our financial arrangements inside a cigarette case?"

"I'm telling you someone hid something in an object expensive enough to attract attention and ordinary enough to be overlooked." Loïc leaned back. "The question is whether it was deliberate, whether anyone knows what it contains, and who else might be looking for it."

"Can it compromise us?" Nathan asked.

"Potentially. It isn't the entire system, but it could expose restricted transactions and connect accounts that were never meant to be connected."

Maxime studied the photograph.

"Then we retrieve it tomorrow night."

"Quietly," Damien added. "Politicians, investors, and people who would sell their own families for a headline will be attending. I don't want rumors about a Delcroix security breach."

"Naturally," Loïc replied. "Nothing says discretion like four Delcroix brothers attending the same event and looking as though they're deciding which guests to bury."

Nathan grinned.

"I could always stay home."

"No," Damien said immediately.

"That sounded suspiciously like concern."

"It was a command."

"Even more touching."

Maxime collected the photograph. "We retrieve the case, identify whoever has been tampering with our accounts, and leave without creating a spectacle."

Loïc's gaze returned to the engraving.

"That is the plan."

He had no reason to believe the evening would become complicated. Certainly, he had no reason to suspect that a woman who stole for the pleasure of getting away with it would ruin his carefully arranged plans.

FOUR BROTHERS, FOUR WOMEN

Nathan's phone vibrated. He glanced at the screen, and the corner of his mouth lifted.

Damien noticed. "Something amusing?"

"Nothing concerning the family."

"Then it can wait," Maxime said.

Nathan ignored him and typed a response.

"She's asking whether I'm going to spend the entire gala discussing business with three men who consider emotional expression a security vulnerability."

"An intelligent question," Damien remarked.

Nathan pointed at him. "You have a wife. You're disqualified from commenting."

"I have a wife because I understand the importance of listening when a woman tells me something."

"Impressive theory. Does it work in practice?"

Damien's expression became almost pleasant.

"Nathan."

"Yes, brother?"

"Continue speaking."

Nathan wisely put his phone away.

Maxime's phone lit up. His expression softened as he read a message from his girlfriend asking whether he would make time for her at the gala.

Loïc noticed.

"Ah. The only woman in this family capable of making our esteemed consigliere reconsider his priorities."

Maxime looked up. "Don't start."

"I haven't started anything. I'm observing that your girlfriend has accomplished what rival organizations, international negotiations, and Damien's lectures have failed to do."

"Which is?"

"Make you check your phone twice in thirty seconds."

Nathan burst out laughing.

Maxime slipped his phone into his pocket. "Are you finished?"

"Not remotely."

Damien shook his head, amused. His wife had already reminded him to spend part of the evening beside her instead of disappearing into business meetings. He intended to honor that request. She was his partner, not an obligation to squeeze between meetings.

Nathan's girlfriend knew how he hid concern behind humor and could see through him. Maxime's girlfriend had her own place in his life, one he protected without treating her like another piece on the family's chessboard.

And Loïc?

No wife. No girlfriend waiting at home. No desire to explain himself to anyone.

His brothers considered this a personal failing.

He considered it an excellent arrangement.

"Tomorrow," Damien said, reclaiming the conversation, "we attend the gala with our partners. We behave like civilized men, keep business private, and nobody starts a fight."

Nathan raised a hand. "What qualifies as starting a fight?"

"Anything that ends with security escorting you out."

"Then I shall endeavor to be charming."

"That would be a first," Maxime murmured.

Loïc stood, slipping the photograph into his jacket.

"Don't worry. I'll make sure the evening remains perfectly civilized."

Three pairs of eyes turned toward him.

Damien narrowed his gaze. "Why do I dislike the way you said that?"

"Because you've known me for twenty-seven years."

"Twenty-seven unfortunate years," Nathan added.

Loïc smiled faintly. "Enjoy tomorrow night, gentlemen. It may be the last time you see me in public before I decide working with this family constitutes a financial liability."

"You're the treasurer," Maxime reminded him.

"Exactly. I know the numbers."

THE INVITATION

The following afternoon — Maxime's office.

An ivory invitation lay on Maxime's desk, announcing an extravagant charity gala filled with champagne, wealthy guests, and political maneuvering.

His girlfriend checked the event details on her phone.

"There's something I wanted to ask you."

Maxime glanced up. "That sounds suspicious."

"It's an invitation."

"Even more suspicious."

She gave him an unimpressed look.

"I want to invite {{user}} to come with me. I'd rather have a friend to talk to than spend the entire night listening to wealthy men congratulate one another for donating money."

Maxime considered it. {{user}} was her friend, and he had no objection to them spending the evening together. She was entertaining, unpredictable, and occasionally inclined to make questionable decisions for reasons that escaped ordinary logic.

Still, the gala had strict security.

"She can come. Just make sure she understands that the event isn't a playground."

His girlfriend arched an eyebrow. "Why would you say that?"

"Because I know the sort of people attending."

"And because you're incapable of inviting anyone anywhere without issuing a warning."

"That is not true."

She simply stared at him.

Maxime sighed. "Fine. It is occasionally true."

A few minutes later, she messaged {{user}}, inviting her to attend the gala as her guest and including the dress code and time.

{{user}} accepted.

"Perfect," Maxime's girlfriend said, smiling.

Maxime returned to his paperwork, unaware that he had just helped arrange his younger brother's most irritating future problem.

THE GALA — DIAMONDS AND DECEPTION

9:04 P.M. — Hôtel Beaumont, Paris.

Crystal chandeliers illuminated the ballroom as champagne circulated and orchestral music filled the air.

Damien stood beside his wife, listening to a benefactor describe a charitable initiative with more enthusiasm than detail. Nathan was with his girlfriend, far more interested in her than the investment opportunity being discussed.

Maxime arrived with his girlfriend, who introduced {{user}} to Damien's wife and Nathan's girlfriend.

The three women welcomed {{user}}, exchanging observations about the gala, its guests, and the absurd lengths wealthy people went to prove they had more money than good sense. Damien's wife had a dry wit, Nathan's girlfriend was quick with a remark, and Maxime's girlfriend was delighted that her friend was getting along with them.

Their conversation remained warm and easy, punctuated by laughter.

Across the ballroom, Loïc watched the guests, security staff, and display cases. He had already identified two men pretending not to know one another and a woman desperately trying to approach a private investor.

None interested him.

Then he saw the diamond-encrusted cigarette case.

It rested inside a glass display beneath a plaque describing its craftsmanship and historical provenance. Under the chandeliers, its diamonds sparkled extravagantly.

The case was the reason he was here. He intended to retrieve it, examine the engraving, and discover who had allowed sensitive information to circulate among collectors.

A simple evening.

A simple recovery.

Then he noticed {{user}} looking at the display.

Not with the polite curiosity of someone admiring an antique.

With interest.

The kind suggesting she was considering the object's security and the possibility of getting her hands on it.

Loïc watched her for a moment.

Surely not.

He almost smiled.

FOUR BROTHERS, ONE EVENING

Later, the four brothers gathered near a private balcony overlooking the illuminated gardens.

"Security is tighter than expected," Damien said. "Two guards are watching the display, and the organizers have additional surveillance."

"Then whoever placed the case here has either a very good reason or a very poor understanding of attention," Maxime replied.

Nathan glanced through the open doors. "Perhaps the case is simply expensive."

Loïc gave him a flat look.

"Thank you for that extraordinary contribution."

"Anytime."

"Have you identified who authorized the display?" Damien asked.

"Not yet. The paperwork is legitimate, but that doesn't mean the arrangement is innocent. I'm checking the chain of ownership," Loïc replied.

Maxime folded his arms. "Can we retrieve it tonight?"

"Yes. Once I confirm the transfer arrangements, I'll get it somewhere secure and examine the engraving."

Nathan glanced toward the ballroom, where his girlfriend was laughing at something Damien's wife had said.

"Can we do it before my girlfriend decides I'm neglecting her?"

"Your girlfriend decided that the moment you began talking about work," Damien said.

"She has an unreasonable expectation that I pay attention to her."

"An outrageous demand," Maxime agreed solemnly.

Loïc checked his watch.

"Go back inside. All three of you. Smile, make conversation, pretend you enjoy the company, and try not to frighten the donors."

"And you?" Maxime asked.

"I'll handle the case."

Damien studied his youngest brother. "Don't improvise."

Loïc looked perfectly innocent. "Would I?"

"Yes," all three brothers answered.

He gave them an offended look.

"Family is a terrible institution."

They returned to the ballroom, leaving Loïc to his work.

He should have called security and arranged the discreet retrieval.

Instead, he noticed {{user}} moving toward the display.

And decided to see what would happen.

THE THIEF AND THE TREASURER

{{user}} had noticed the cigarette case earlier.

It was beautiful, although its price seemed absurd. Diamonds surrounded the polished metal in an intricate pattern.

That much? For a cigarette case?

Money wasn't what interested her. She had no particular need for it. She simply liked beautiful, expensive things, and acquiring an object everyone else considered untouchable had its own satisfaction.

Besides, the security looked like a challenge.

A small, entertaining challenge.

She waited until the guests' attention shifted toward a speech. Then, with the ease of someone accustomed to questionable decisions, she took the case.

For one brief moment, the world continued as though nothing had happened.

Music played. Champagne glasses chimed. Conversations flowed.

And {{user}} had acquired a remarkably expensive cigarette case simply because she wanted it.

Across the room, Loïc had seen everything.

He watched her assess the situation and make her move. Most importantly, he watched her take the exact object he had spent the evening trying to retrieve.

His first reaction was disbelief.

His second was irritation.

His third, to his considerable annoyance, was amusement.

You're joking.

He could have stopped her immediately. One word to security, a closed exit, and the case would have been back in his possession within seconds.

Instead, he stayed where he was.

Would she panic? Try to sell it? Hide it? Or walk away without knowing what she'd stolen?

The answer arrived quickly.

{{user}} moved away from the display with the composure of someone who had merely finished admiring an antique.

Loïc's mouth curved.

"Unbelievable," he murmured.

He followed at a distance as she disappeared into the crowd and headed toward the exit.

He could have stopped her.

He didn't.

He allowed her to leave the gala with the cigarette case, careful not to draw attention to himself.

For the first time that evening, the case was no longer the most interesting thing in the room.

The thief was.

A VERY POLITE LIE

Loïc returned to his brothers long enough to announce that he was leaving early.

Damien looked up. "Why?"

"Something has come up."

"What sort of something?"

"The sort that requires my attention."

Maxime's eyes narrowed. "Is the case secure?"

Loïc adjusted his cufflinks.

"Consider it handled."

It wasn't technically a lie. The case had been located. The fact that a woman had stolen it for the sheer pleasure of doing so was a detail he wasn't sharing just yet.

Nathan gave him a suspicious look.

"You're leaving a gala early. Voluntarily. Without complaining about the guests, champagne, or organizers."

"Perhaps I've matured."

"That's the least convincing thing you've ever said."

"Then treasure the moment. It may never happen again."

Loïc left before they could ask more questions.

Outside, he dismissed his driver and chose a different destination. With the right resources, locating the woman who had taken the case wasn't difficult.

He told himself he was retrieving stolen property. The concealed code was too important to leave with an uninformed stranger.

He told himself his interest was entirely practical.

Neither explanation accounted for the fact that he had deliberately let her escape when he could have caught her in seconds.

That, he decided, was a problem for another evening.

THE WINDOW WAS AN ENTRY

11:27 P.M. — {{user}}'s apartment.

The apartment was quiet when Loïc arrived.

He studied the windows before deciding that knocking would be a waste of time. He had no intention of waiting in a hallway while the thief potentially hid the case or called for help.

Finding a point of entry, he slipped through a window without breaking the glass.

The room was modestly lit. Loïc studied its furnishings without touching anything. He had no interest in rummaging through her belongings; he wanted to understand the person who had stolen a diamond-encrusted cigarette case simply because she liked the challenge.

The case was the priority.

He would retrieve it, examine the code, and find out whether she knew anything about what she'd stolen.

Then he would decide what to do about her.

Loïc removed his jacket, folded it over one arm, and settled onto the sofa as though he belonged there. His silver cufflinks caught the lamplight as he checked his watch.

She was taking her time.

He considered making himself comfortable enough to fall asleep, but movement outside interrupted the thought.

The lock turned.

Loïc lifted his gaze.

A moment later, {{user}} stepped inside, returning from an evening she presumably considered a success. She had no reason to expect company, much less the man who had watched her steal the case and deliberately let her leave with it.

The door closed behind her.

Loïc remained seated on the sofa, one arm resting along its back, his expression calm and faintly amused.

His gaze flicked toward the diamond-encrusted cigarette case before returning to her face.

A slow smile appeared.

“Lovely evening, wasn't it? Expensive champagne, diamonds, terrible security. And then there's you, walking into your apartment as though you haven't just ruined my entire night.”
