My Husband Took His Female Colleague to My Inherited Lake House for ‘Business Trips’ — But He Had No Idea I’d Already Installed Cameras #5

The narrator of this story, Sandra, reflects on the journey that led her to take control of her life after discovering her husband’s infidelity. For seven years, Sandra thought she had the perfect marriage. She and her husband, Luke, appeared to be the ideal couple—supporting each other’s careers, planning weekend getaways, and dreaming about a family they would start “someday soon.” On the surface, their life seemed like a well-rehearsed performance that everyone around them envied.

Sandra worked as a senior editor at a publishing house in Chicago, and the past year had been particularly chaotic. With multiple major releases to manage, she was overwhelmed by deadlines, manuscripts, meetings, and marketing plans. Most nights, she would collapse into bed after midnight, still thinking about the next day’s tasks. Luke would look at her, smile, and offer words of comfort about how hard she was working. Looking back, Sandra realizes that her hectic work life gave Luke the perfect opportunity to carry on with his secret life without being questioned.

A key element of Sandra’s personal life was the lake house she inherited from her grandmother two years ago. Located in northern Wisconsin, the house was her childhood sanctuary—filled with memories of summers spent catching fireflies, baking with her grandma, and reading on the dock. After her grandmother passed away, Sandra made it clear to Luke that the lake house was hers alone. He was allowed to visit, but she didn’t give him a key and made it clear he wasn’t welcome there alone. Little did she know, Luke had been going there on his own, under the guise of business trips.

Luke’s frequent absences began to raise questions when he started taking “business trips” more often. He explained the increase in travel as being due to a “client pipeline expansion,” but Sandra didn’t think much of it—she was too consumed with her own work to question him. Luke would leave for days at a time, and Sandra would spend her evenings alone, enjoying quiet time with her dog and takeout food. This routine continued until one morning, when Sandra received a call from an unexpected source—a Wisconsin area code flashed on her phone.

The call came from Mr. Jensen, the elderly neighbor who had lived next door to Sandra’s grandmother. Mr. Jensen mentioned seeing a man at the lake house, someone who didn’t look familiar, unlocking the door as though he owned the place. Sandra tried to brush it off, suggesting it was likely a maintenance worker. But Mr. Jensen wasn’t convinced. He mentioned seeing the man with a nice car and carrying grocery bags, which made Sandra’s stomach flip. Luke had been in Philadelphia the previous weekend, or so he had said. Had he lied to her?

That night, Sandra didn’t confront Luke immediately. However, her gut instinct told her to investigate further. The following weekend, when Luke left for another “conference,” Sandra decided to act. She called in sick to work, packed a bag, and drove four hours to the lake house. Upon arriving, everything appeared normal at first glance. The porch was swept clean, and the windows were shut. But when she unlocked the door, she immediately noticed something felt different. The usual musty smell was replaced by the scent of something fresher, as if the house had been aired out. She explored each room slowly, taking in the details.

In the kitchen, she found a wine glass with a smudge of coral lipstick on the rim. A throw blanket draped over the couch caught her eye—it was one she had never seen before. The bed was made with hospital corners, not her usual messy tuck, and the pillows were arranged more neatly than she ever bothered to do. In the bathroom, Sandra found a long blonde hair caught in the drain. She knew it wasn’t hers, as she had shoulder-length dark brown hair. As she looked through the trash, she discovered takeout containers from a local restaurant, along with a receipt for two meals—one of which was Luke’s favorite. The evidence became undeniable: Luke had been bringing another woman to the lake house.

Shaken but determined, Sandra realized she needed more concrete evidence. She went to an electronics store and purchased a security system with three cameras. She installed one at the front door, one at the back entrance, and the third in a vintage bookend on the living room shelf, discreetly monitoring the house. As she set up the cameras, she tried to justify it to herself as a precaution against burglars, but deep down, she knew she was preparing to expose Luke’s betrayal.

When Luke returned from his “business trip” two days later, Sandra greeted him with a calm demeanor. She asked him about his trip, and he gave his usual response about the meetings going well and his lack of time for anything beyond work. She didn’t confront him directly but continued to play along. The next week, when Luke announced another trip to Minnesota, Sandra saw an opportunity to test him further. She pretended to be supportive, but inside, she was already making plans.

The following Friday, Sandra received an alert on her phone: a motion detection at the front door. Her heart raced as she opened the live feed from the cameras. There was Luke, unlocking the door with a woman behind him. The woman had long blonde hair and carried a designer handbag. Sandra watched in silence as the two of them entered the house, laughing together as if it was their own private paradise.

Instead of confronting Luke immediately, Sandra calmly watched the footage before closing the app. She had the proof she needed, and now, she needed to figure out her next move. Over the next few days, she carefully crafted a plan. She continued to act normal, listening to Luke’s lies about his business trips and corporate dinners. When Luke mentioned another upcoming trip, Sandra seized the moment.

“I think I’ll come with you this time,” she said over breakfast. Luke, visibly startled, tried to convince her it would be boring and not worth it. But Sandra smiled and revealed that she had already spoken to his colleague, Tim, who confirmed that Luke’s trip had been rescheduled. “We’ll just spend the weekend at the lake house,” Sandra suggested. Luke reluctantly agreed.

They drove up to the lake house, with Luke trying to act like everything was normal. Once there, Sandra prepared lunch, while Luke became increasingly anxious. After eating, Sandra told him she had a surprise for him—a slideshow. He was confused, but his demeanor shifted as she turned on the TV. The footage of him and his mistress at the lake house played on the screen. Sandra watched as his face drained of color.

“I can explain—” Luke began, but Sandra stopped him. “Save it,” she said, her voice calm. “What’s there to explain? That you’ve been lying for months? That you brought another woman here?”

Sandra handed him the divorce papers she had prepared in advance, telling him he had until Monday to sign them, or she would send the footage to everyone—his boss, his mistress’s husband, and anyone else who needed to know. Luke left that afternoon, defeated and silent.

That night, Sandra sat on the dock, wrapped in her grandmother’s quilt, watching the sunset. For the first time, she felt a sense of peace. It wasn’t about the lake house anymore—it was about reclaiming her sense of self-worth and trusting her instincts. Sandra learned that sometimes the most valuable thing isn’t a property, but the ability to stand up for yourself and protect your peace.

The story concludes with Sandra’s reflection on how trusting one’s gut, protecting one’s peace, and knowing your own worth are essential in navigating life’s challenges.
