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

I never saw myself installing concealed cameras in my home. My instinct told me Luke’s absences were more than spreadsheets and client meetings when my husband’s “business trips” rang hollow and an old neighbor contacted with queries.

I believed everyone envied my marriage for seven years. Luke and I lived like synchronized swimmers. Supporting each other’s work, planning weekend trips, and dreaming about our “someday soon.” family.

In my pursuit of the perfect existence, I missed all the warning flags.

The past year has been pandemonium for me as a Chicago publishing firm senior editor. My team had three major releases, and manuscripts, author meetings, and marketing strategies flooded me.

I went to bed at midnight worried about tomorrow’s deadlines most evenings. Luke would smile at me and murmur about my hard work.

I see now how handy my diversion was for him.

My grandma left me a peaceful lake cottage two years ago. It’s at the end of a scarcely paved road in northern Wisconsin, surrounded by tall trees and beautiful water.

The old-fashioned cozy has charm and memories. Catching fireflies, preparing peach cobbler with my granny, and reading on the dock till my skin went golden was my summer routine.

After grandmother died, I took it as my secure spot.

I told Luke it was mine. I let him visit and we remained one weekend to paint the bathroom and tidy the attic. It ended there.

No key. No solo trips. At least not that I knew.

For six months, Luke has taken several “business trips.” He attributed his increased travel to a “client pipeline expansion.”

My doubts were few.

Work kept me too busy to worry about it.

After he promised to return in a few days, I’d have peaceful evenings with my dog and expensive takeout.

Everything was fine until I learnt something unexpected one morning.

My phone rang as I rushed to work with damp hair from the shower. Caller ID revealed Wisconsin.

“Hello?” I said, holding the phone between my ears and shoulder to find my shoe.

“Sandra? It’s Mr. Jensen.” The voice brought back lake and summer memories.

Every morning at daybreak, my grandma’s old neighbor Mr. Jensen walked his dog around the lake.

“Hey, Mr. J! How are you?” I put on my shoe from under,

“I’m fine, sweetheart. Just wanted to check in. Everything okay with the house?”

I halted. “Of course. Why wouldn’t it be?”

“I saw someone up there last weekend. Tall guy. He was unlocking the door like he owned the place. Didn’t recognize him.”

My stomach flipped.

“Oh,” I remarked calmly, my heart racing. “Probably a maintenance worker.”

He grunted. “Didn’t look like he was fixing anything. He had a nice car and was carrying grocery bags… Just thought I’d mention it.”

I was frozen in my bedroom when we hung up.

Luke visited Philadelphia last weekend. My thoughts. He was in Philadelphia? Has he lied to me?

I didn’t talk to him that night. Something warned me not to let this go.

Luke went to another “conference.” After his car drove off our street, I packed some clothes, called in sick, and drove four hours to my lake property.

Everything seemed normal at first. The porch was cleaned and windows covered.

With shaky hands, I unlocked the front door.

The inside smelled strange. It wasn’t musty as it typically would after sitting empty, but fresh like someone had aired it out.

I gently strolled around each room, seeing things that gave me shivers.

A wine glass in the sink with coral lipstick on the rim.

A throw blanket covered the couch. Never seen anything like that.

My sloppy tuck was replaced with medical corners on the bed.

I would have never bothered arranging the pillows.

I noticed a long blonde hair in the bathroom drain.

It wasn’t mine. I have shoulder-length dark brown hair.

Two local restaurant takeaway containers and a supper for two receipt were in the garbage. Luke’s favorite foods were included.

I fell into my grandmother’s rocking rocker as I understood what was happening. The thought of Luke with another woman made my hands shake.

Truth was obvious, but I wanted irrefutable proof.

That afternoon, I drove to the local electronics store and bought a security system. I could link three cameras to my phone.

I carefully set them up. One at each entrance: front, rear, and in an antique bookend on the living room shelf.

I added, “Just in case of thieves,” to the vacant home, as if it required explanation. But deep down? I knew what I wanted.

My heart was hollow as I drove home that night. Two days later, Luke returned from his “conference” and I said hi and enquired about his vacation.

He remarked, “It was great,” unpacking his luggage. “The client meetings went well.”

I nodded and questioned his restaurant experiences.

“Nothing special,” he shrugged. “Mostly room service. I was swamped with work.”

Every phrase penetrated me like a needle.

The next Thursday, Luke announced another trip.

“This time, Minnesota,” he continued. “Back Sunday night.”

I grinned. “You’re working so hard lately. I’m proud of you.”

I was reading manuscript revisions Friday morning when my phone chimed.

Front door motion alert. Entrance detected.

I launched the live broadcast with a racing heart.

Luke unlocked my grandmother’s front door. He was followed by a thin blonde woman with a nice purse. He held open the door, making her laugh.

“Welcome back to paradise, babe,” he said.

I stood stunned as they entered my sanctuary laughing like it was theirs.

I didn’t weep. Not a tear.

I saw them quietly go around my lake house like they owned it.

After closing the app, I took action.

Over the next week, I planned while Luke was home, pretending everything was normal. I patiently listened to his elaborate stories about corporate dinners and presentation failures when I enquired about his “work trip”.

He proposed another vacation, so I sprang my trap.

I said “You know what?” during breakfast. “I think I’ll come with you this time.”

The color left his face. “What? No, honey, it’ll be boring. Just meetings all day.”

I grinned. “Actually, I was thinking… instead of your boring work trip, what if we took a long weekend at the lake house? Just us. No phones. No distractions.”

Fumbling with his coffee mug, he paused. “I can’t just cancel—”

“I already spoke to Tim in your office,” I lied. “He said the Minnesota client rescheduled. You’re clear until Tuesday.”

Checkmate.

Luke faltered, “You… talked to Tim?”

“I wanted to surprise you with this getaway,” I grabbed his hand. “We’ve both been so busy. I miss you.”

What was his choice? He agreed.

On Friday morning, he played his normal music like nothing had occurred. I held his hand during red lights and expressed my excitement for our romantic weekend.

I cooked lunch at the lake cottage as he unloaded, appearing apprehensive as he looked about.

He presumably wanted to know whether his mistress left any proof.

“I’ve got a surprise for you,” I remarked after eating.

His face brightened. “What kind?”

“I put together a little slideshow. Since you’ve been enjoying the lake house so much lately.”

His face froze. “What do you mean?”

I switched on the TV and played the clip silently.

The tape showed him unlocking the door, her laughing as she entered, and them dancing in my living room.

I’ll never forget his expression.

“Sandra, I can explain—”

“Save it,” I answered quietly. “What’s there to explain? That you stole the keys to my property? That you’ve been lying for months? That you brought another woman to the one place that matters most to me?”

He cried, “You spied on me?” in fear and wrath. “That’s insane! How could you even do that?”

Gaslighting. Classic cheating.

“What’s insane is thinking you wouldn’t get caught,” I said. “What’s insane is that you’re blaming me for spying on you when you know you’re the one who messed up.”

I gave him a divorce packet with completed documents.

“I’ve been talking to my lawyer for weeks. You have until Monday to sign, or the footage goes to everyone. By everyone, I mean your boss, who thinks you’ve been working so hard. And her husband too. Yeah, I’ve done my homework. I know your girlfriend’s married.”

Luke departed that day, quiet and disheartened.

Under my grandmother’s comforter, I watched the water become gold at twilight on the pier. Nothing broke me.

Instead, I felt like I’d entered the light.

Because I understood sometimes the most precious thing isn’t an inherited mansion.

Knowing your worth. This is learning to trust your instincts even when the truth scares you.

If you’re torn between the love you want and the silent alarm in your breast, listen. Investigate. Honor your peace like a right. Because it is.
