Kristina was finishing her third coffee of the morning when Olga burst into the conference room wearing the smile of a predator pretending to be harmless

ДЕТИ

Kristina was finishing her third coffee of the morning when Olga swept into the meeting room with the smile of a hunter dressed up as prey. Her sister-in-law had a talent for showing up at exactly the wrong moment, but today there was something especially charged in the way she moved.

“Kristina, hi. How’s the presentation going?” Olga purred, lowering herself into the chair across from her. “Board meeting tomorrow. You must be nervous.”

Kristina looked up from her laptop.

A month of sleepless nights had clearly taken its toll, but the project was worth every hour. She had built a revolutionary logistics automation system for mid-sized companies, a product that could bring in millions. At last, her husband’s family business had a chance to gain a real advantage over its competitors.

“Everything’s fine,” she said, saving the file with quiet satisfaction. “The presentation is almost done.”

“Can I see it?” Olga was already leaning toward the screen. “I work in this company too. I’m dying to see what brilliant thing our little star has created.”

Something in Olga’s voice made Kristina wary, but saying no would only trigger another family fight. Boris was always asking her not to “start conflicts” with his sister.

“Sure, take a look,” Kristina said, turning the laptop toward her. “Just don’t touch anything. I still need to make a few final edits.”

Olga bent over the screen. Her eyes skimmed across the slides. Optimization algorithms, integration schemes, financial forecasts—everything Kristina had spent the past few weeks building into a flawless project structure.

“Impressive,” Olga said slowly. “And what’s this module?”

Kristina patiently explained the logic behind the machine-learning system, how it would adapt to the specific needs of each client.

Olga nodded, asked questions, and played the role of the interested colleague. It all seemed normal enough. The family had always taken an interest in one another’s work.

“Tell me,” Olga said, snapping a photo of the screen, “aren’t you afraid competitors might steal your idea? I want to post something for social media. Show everyone how efficiently we work.”

“Olga, don’t!” Kristina shut the laptop at once. “This project is confidential.”

“Oh, come on. Why are you acting so paranoid? That’s ridiculous.”

For the rest of the day, a strange sense of unease followed her.

Olga kept dropping by the meeting room, asking too many questions, showing far too much interest in the technical details.

Maybe it was just exhaustion. For weeks, Kristina had practically been living at the office, fine-tuning every detail.

That evening, Boris was massaging her shoulders while she reviewed the presentation one last time.

“Tomorrow you’ll finally show everyone—including my parents—what you’re capable of,” he said proudly. “Mom is already planning a celebration dinner for after your success.”

“And what if they don’t approve it?”

“They will,” Boris said with absolute confidence. “The project is brilliant. I’ve seen it. Dad will definitely love how profitable it is.”

That night, Kristina could not sleep.

Tomorrow would decide everything. She would find out whether she could finally become a true part of the family business or whether she would always remain nothing more than “the younger son’s wife.”

She had worked at the company for three years, and still she had to prove—to her in-laws and everyone else—that she was truly competent.

The next morning, she woke with the uneasy feeling that something was wrong, though she could not explain what.

The board meeting was scheduled for eleven o’clock.

Kristina arrived early, checked the equipment, and laid out the materials.

The atmosphere in the room felt familiar. Her mother-in-law, Galina Petrovna, in a severe tailored suit, was leafing through documents. Her father-in-law, Anatoly Mikhailovich, was focused on financial reports.

Boris gave his wife an encouraging wink.

“Where’s Olga?” Galina Petrovna asked, glancing at the clock.

“She’ll be here any minute,” Anatoly Mikhailovich replied. “She said she had something to present too.”

Kristina frowned.

No one had mentioned that Olga would be presenting anything that day. The board agenda was usually discussed ahead of time.

Olga arrived precisely at eleven, carrying her personal laptop and a flash drive. The same predatory smile from the day before was on her face.

“Good morning, everyone,” she sang. “Mom, Dad, I’m ready to present my project.”

“Your project?” Kristina repeated. “Olga, we agreed that today I—”

“Kristina, don’t worry,” Olga cut in, already connecting her laptop to the projector. “You can speak after me. Assuming, of course, there’s any time left.”

The first slide appeared on the screen:

Revolutionary Logistics Automation System for Mid-Sized Businesses. Project Author: Olga Sokolova.

Kristina stopped breathing.

Her diagrams. Her algorithms. Her financial calculations. Everything was identical down to the last comma. Only the author’s name had been changed.

“Olga, what is this?” Kristina whispered.

“My project,” Olga answered coolly, and began her presentation.

She talked about the machine-learning system, the optimization of logistics chains, and a projected twenty million rubles in profit in the very first year. Every sentence, every technical phrase, had been stolen from the conversation they had the day before.

“Remarkable work, sweetheart,” Anatoly Mikhailovich said, nodding approvingly. “You can see how much effort you put into it. Well done.”

“I spent almost six months on it, Dad,” Olga lied. “I barely slept. I worked through every detail.”

Kristina turned to look at her husband.

Boris was staring at the screen with admiration, clearly not understanding what was happening. He had never really paid attention to the technical side of her work. To him, all IT projects looked more or less alike.

“Stop,” Kristina finally said. “That’s my project. I developed it. I was supposed to present it today.”

“Kristina,” Galina Petrovna said with a patronizing smile, “there’s no need to make things up out of jealousy. We all know our Olga is a gifted girl. She was interested in programming back in college. And now, at last, we’re seeing the results of all that talent. Wonderful.”

“Programming?” Kristina felt hysteria rising in her chest. “Yesterday she didn’t even know the difference between an API and an SDK.”

“My dear,” Anatoly Mikhailovich interrupted, “let’s keep emotions out of this. Olga presented a finished project with real numbers. If you have something similar, you can show it next time.”

“Similar? These materials are completely identical!”

Olga clicked to the next slide: the system architecture diagram Kristina had drawn on the whiteboard a month earlier. Even the colors were exactly the same.

“I understand that Kristina wants to contribute to the company’s growth,” Olga said with fake sympathy, “but maybe she should start with something simpler. Logistics is a difficult field.”

The board nodded in agreement.

There was unmistakable satisfaction in her mother-in-law’s eyes. At last, their “brilliant” daughter had proven herself, leaving the daughter-in-law far behind.

The applause in the conference room crashed like hammer blows.

Anatoly Mikhailovich clapped with particular enthusiasm. Galina Petrovna smiled proudly, and Boris even stood up to applaud his sister.

Kristina stood in the deafening silence of her own humiliation.

“The project is approved for implementation,” her father-in-law declared ceremoniously. “Olga, you’ve exceeded all expectations. I’m appointing you head of the IT division with a salary of three hundred thousand rubles a month.”

“Daddy, thank you!” Olga cried, hugging him theatrically, while throwing Kristina a triumphant glance.

“Boris, are you proud of your sister?” Galina Petrovna asked.

“Of course, Mom. I always knew Olga was talented. She’s going to go far.”

Kristina felt nausea rise in her throat. The worst part was not Olga’s betrayal—she had always known that was possible. What broke her was her husband’s indifference. He did not even try to defend her.

“Boris,” she said quietly, “you know that was my project.”

He gave an awkward shrug.

“Kris, I mean… I don’t really understand all that technical stuff. Maybe you were both working on something similar?”

“Similar? Are you serious? I told you every night about the adaptive routing algorithm!”

“My dear,” Galina Petrovna cut in, “let’s not ruin a family celebration. Olga can share her experience with you, and together you’ll create something wonderful.”

Share her experience.

Kristina clenched her fists so tightly that her nails dug into her palms, just to keep from saying something unforgivable.

Meanwhile, Olga packed up her laptop, softly whistling to herself.

“Kristina,” she said in a honeyed voice, “don’t be so upset. Next time, I’m sure you’ll come up with something of your own.”

Something of her own. After a month of fourteen-hour days, endless code revisions, and the breakthrough solution to the scaling problem that had come to her at three in the morning.

“You know what, Olga,” Kristina said through her teeth, surprised by how calm she sounded. “You’re right. I will absolutely come up with something of my own. But you? Probably not.”

The rest of the day passed in a blur.

Colleagues flooded Olga with congratulations, discussed the future of the project, and made plans for its rollout.

Kristina sat in her office, mechanically replying to emails while replaying every moment of the day in her mind.

The project really was brilliant. The system she had created could adapt to any business process, learn from customer data, and optimize routes down to the minute.

Competitors would tear themselves apart trying to build something similar.

That evening, her in-laws’ house was full of celebration.

Galina Petrovna had truly prepared a festive dinner. At the center of the table stood a cake with the words: Proud of Our Clever Girl.

“Kristina, why do you look so unhappy?” her mother-in-law asked, pouring champagne. “You should be celebrating. We have a new talent in the family.”

“I am celebrating,” Kristina replied dryly, refusing the alcohol.

“Mom, Kris is a little upset about the presentation,” Boris explained. “She had a project too.”

“Oh, is that all?” Galina Petrovna said with a knowing nod. “My dear, don’t be upset. Everything has its time. It simply means you haven’t grown into big business yet. As they say, the quick eat the slow. And that’s exactly what happened to you.”

Kristina pushed back her chair.

“I see. Excuse me. I have a headache. I’m going to lie down.”

In the bedroom, she took out her laptop and opened the backup copy of the project. Everything was still there: every line of code, every diagram, every calculation.

And that one crucial solution—the one that made the entire system truly revolutionary.

The one she had not had time to tell Olga about.

Kristina did not sleep at all that night. She lay staring at the ceiling, running through her plan again and again.

What she was about to do might have seemed cruel. But after the humiliation she had suffered that day, she had no pity left.

Olga had chosen to steal someone else’s work. Fine. Then she could have all of it. Including the hidden surprises.

The next day, the office buzzed with energy.

Anatoly Mikhailovich had already scheduled meetings with potential clients, the marketing department was preparing promotional materials, and the IT team had been instructed to begin technical development under the guidance of the “project author.”

“Kristina,” Olga called, gliding past her office, “could you help the team with the code? You understand that a department head should focus on strategic issues, not dig around in technical details.”

Of course. Stealing the idea was strategy. Actually making it work was for someone else.

“I’d be happy to help,” Kristina said with a smile. “I have some groundwork on a similar subject.”

Over the next two weeks, she worked closely with the programmers, carefully recreating the stolen project. Every module, every function, every algorithm was implemented exactly as originally intended.

From time to time, Olga dropped by the team, asked a few vague questions, and was always told that everything was on track.

“And what’s this part for?” Olga asked once, pointing to a block of code Kristina had added at the very end.

“A deep-learning module,” Kristina replied. “To improve forecasting accuracy. You talked about it in your presentation. Don’t you remember?”

Olga nodded and pretended she understood, though she clearly had no idea what she was looking at. What mattered was that the system behaved exactly the way it had been promised to investors: it optimized routes, reduced costs, and improved efficiency.

The first test runs were a triumph.

Test data was processed at astonishing speed, the algorithms delivered phenomenal accuracy, and the savings reached twenty percent—more than anyone had projected.

“Olga, you’re a genius!” Anatoly Mikhailovich exclaimed. “This system is better than we ever expected.”

The contracts were set to be signed on Friday. Three major logistics companies were ready to pay five million rubles each for implementation. Fifteen million rubles in one stroke—the largest deal in the history of the family business.

On Thursday evening, Kristina stayed late at the office.

Everyone else had gone home, preparing for the next day’s triumph. She opened the system code and located the exact module Olga had asked about: innocent-looking lines that were meant to activate seventy-two hours after the first launch.

Seventy-two hours. Just enough time for the grand presentation, the signing of contracts, and the collection of the advance payments. After that, the system would begin behaving in ways no client expected.

The deep-learning module was real. But instead of learning optimization, it learned sabotage. Slowly, invisibly, it began producing faulty routes. At first, the errors were minor. Then they grew.

Within a month, the system would become a chaos engine, sending trucks in the wrong direction and creating traffic jams instead of eliminating them.

Kristina saved the file and shut down the computer.

Tomorrow Olga would get her shining moment. The day after that too. And then, three days later, the truly interesting part would begin.

At home, a festive dinner was waiting for her in honor of the next day’s deal. Boris talked excitedly about expanding the business, her mother-in-law dreamed aloud about buying a new country house, and Olga was already picking out a car she planned to buy with her bonus.

“Kristina, don’t look so gloomy,” Galina Petrovna said with a smirk. “One day, you might manage to rise above mediocrity too.”

“I’m not gloomy,” Kristina replied sincerely. “I just know that sooner or later everyone gets exactly what they deserve. Me included.”

The first call came on Monday at nine in the morning.

The CEO of Trans-Logistics was shouting so loudly into the phone that Anatoly Mikhailovich had to hold it away from his ear.

“Your miracle system sent twenty trucks carrying frozen products to Tver instead of Tula! We lost half a million rubles in spoiled goods! I demand a full refund and complete compensation immediately!”

The next call came from Fast Delivery.

“What kind of joke is this? Your algorithms are sending our couriers in circles! Clients are furious, and our ratings are collapsing because of you!”

By lunchtime, the phone had not stopped ringing. All three companies that had signed contracts were demanding compensation. The system that was supposed to save millions had become a machine for destroying businesses.

“Olga!” Anatoly Mikhailovich roared. “Fix your code immediately!”

Olga ran around the office with red, tear-swollen eyes, hammering at the keyboard, calling every programmer she knew.

But how could she fix something she did not understand? Stolen knowledge does not come with the ability to use it.

“Dad, I don’t understand what’s happening,” she sobbed. “The system worked perfectly!”

“Figure it out however you want! Our reputation is on the line!”

By Tuesday, things had become even worse.

Trans-Logistics filed a lawsuit for fifteen million rubles: five million in returned advance payment plus ten million in damages.

The other clients were preparing similar claims.

Olga came running to Kristina on Wednesday, when it became obvious the company was on the verge of bankruptcy.

“Kristina, please help me! I know you understand programming better than I do. Find the error in the code!”

“The error?” Kristina asked calmly, taking another sip of coffee. “But isn’t this your brilliant project?”

“Kristina, please! We both know whose project this really is! Mom and Dad will lose their minds if the company goes bankrupt. The whole family business will collapse!”

“You know, Olga,” Kristina said with a sigh, “I can help. But first I want something clarified. Let’s call a board meeting.”

An emergency meeting was held that very same day.

Anatoly Mikhailovich looked as though he had aged ten years. Galina Petrovna drummed her fingers nervously against the table, and Boris sat there glancing around in confusion.

“All right,” Kristina began. “I have good news. I know how to solve the problem. And Olga is going to explain to the board exactly how her ‘original’ project came into existence.”

“Kristina, why do we need that right now? We have a disaster on our hands!” Boris protested.

“I know. But without the truth, we’re going nowhere. Olga, tell them.”

Olga shrank in her chair, but she had no choice. Through tears, she admitted that she had looked over Kristina’s project, copied all the materials, and presented them as her own.

A dead silence fell over the room.

“So…” Anatoly Mikhailovich said slowly, “you stole someone else’s work?”

“Daddy, I didn’t mean… it just happened…”

“How does something like that ‘just happen’?” her father roared. “You put everything we’ve spent twenty years building at risk!”

Galina Petrovna began to cry silently. Boris stared at his wife with a guilty expression.

“Olga, pack your things immediately,” Anatoly Mikhailovich said. “You no longer work for this company. And don’t expect any inheritance.”

“Dad, no!” Olga wailed, but he would not even listen.

“Kristina,” Galina Petrovna said, turning to her daughter-in-law, “forgive us. Can you fix the system?”

“I can,” Kristina replied with a nod. “But I have conditions.”

“Anything,” Anatoly Mikhailovich said at once.

“A seat on the board with voting rights. Head of IT salary—four hundred thousand rubles a month. And full authority over all technical projects.”

Her in-laws exchanged a glance and both nodded immediately.

“Agreed,” Anatoly Mikhailovich said sharply. “Just save the company.”

Kristina opened her laptop and, within half an hour, removed the destructive module. The system ran perfectly again. By the end of the week, the clients had withdrawn their lawsuits and even ordered additional features.

A month later, the company had not only restored its reputation but had also won an award for IT Solution of the Year.

Kristina was giving interviews to industry publications, speaking at conferences, and frequently being invited to serve on judging panels for technical competitions.

Olga found a job as a manager at a small company for fifty thousand rubles a month. From time to time, the women crossed paths in the city. The former sister-in-law would quickly look away and cross to the other side of the street.

“Do you ever feel sorry for her?” Boris asked once.

“Everyone got exactly what they deserved,” Kristina said calmly, scrolling through partnership offers from international corporations. “Olga wanted someone else’s success. I wanted justice. And in the end, justice won.”

If you want, I can also turn this into a more emotional, more literary English version for story publishing.
