My son drew a strange man — when I asked him, he said, “He comes to see mom when you’re at work.”

I was stunned when my son started drawing a smiling stranger. “He comes to see mom when you’re at work,” Oliver said innocently. At first, I dismissed it as a child’s fantasy, but soon I saw a mysterious man enter our house, leading to a chilling quest for the truth.

I found the drawing while cleaning the dining table. Most of Oliver’s drawings were what you would expect from a six-year-old: dinosaurs with rainbow scales, our house with a chimney that looked like a volcano, and stick figures of our family holding hands. But this drawing made me stop.

Among the crayon doodles, there was a tall figure with unusually long arms and enormous hands, dressed in what seemed to be a suit. The figure had a huge smile that took up almost its entire face.

“Oliver,” I called, trying to keep my voice casual while my fingers crinkled the edge of the paper. “Is that me in the drawing? Who is it?”

My son looked up from his LEGOs, his blue eyes shining with excitement.

The plastic blocks clattered as he dropped them on the wooden floor. “That’s Mr. Smiles, dad! He’s mom’s new friend. He comes to see her when you’re at work.”

My heart skipped a beat. Laura and I had been married for nine years. We’d had our ups and downs like any couple: job changes, family losses, promotions, and anniversaries. But never, not for a moment, did I think she…

No, I pushed the thought away. There had to be a reasonable explanation. Laura wasn’t that kind of person. We had built too much together.

“When does he come?” I asked, proud of how steady my voice remained despite the trembling in my hands.

Oliver stacked another block on his tower, concentrating with his tongue sticking out.

“Sometimes in the morning. Sometimes at night. He always makes mom and me laugh.” He looked up, suddenly serious, his little face scrunched with the weight of importance. “But dad, it’s a secret! Don’t tell anyone!”

The mention of laughter and secrets made my stomach freeze.

That night, I could barely sleep, watching Laura’s peaceful face in the dark. The constant rhythm of her breathing, which had once been comforting, now felt like a provocation. Every time she shifted in her sleep, I wondered what she was dreaming about. Who was she dreaming about?

The next day, I left work early, parked on the street in front of our house, and waited. The autumn air was getting colder as the afternoon progressed, and fallen leaves slid over my windshield. Shortly after 3 p.m., a sleek black car stopped in our driveway.

A tall, slender man got out and marched to the front door. Even from that distance, I could see his wide smile when Laura greeted him. The door closed behind them.

I gripped the steering wheel so tightly my fingers turned white; the leather creaked under my pressure.

“Maybe this is all in my head,” I whispered to myself, watching my breath fog up the window. “But if I’m wrong, I need to make sure.”

In the following weeks, I started buying flowers and gifts for Laura, trying to rekindle our connection, but I also began documenting everything.

The evidence piled up: receipts for dinners I didn’t attend, calls she went to take outside, and of course, more drawings of “Mr. Smiles” by Oliver. Each new piece of evidence felt like another brick in a wall that was rising between us.

Laura noticed the change in me.

“Are you feeling okay?” she asked one day, touching my forehead with concern. “Lately, you seem distracted.”

The genuine worry in her voice confused me even more. How could she act so normally if she was hiding something so big?

“Do you have someone else?” I asked.

“Someone else?” Laura looked at me with wide eyes, then shook her head.

“Of course not, dear!” She laughed a little. “How could you think that?”

Maybe I should have confronted her right then, but all my evidence was circumstantial. I needed concrete proof.

One Friday night, I told Laura I’d be working late. Instead, I set up a hidden camera on the bookshelf in the living room and watched the feed from my car parked around the corner.

The blue glow of my phone screen lit up as I waited, my coffee cooling in the cup holder.

Right on time, Mr. Smiles arrived, and Laura greeted him with that same warm smile she used to reserve for me.

But then something strange happened. He didn’t settle on the couch or share a private dinner. Instead, my sister came in, and Oliver came downstairs with a beaming smile. More people arrived! Neighbors and friends.

Did they know? And worse, were they planning a secret gathering? I watched silently, stunned, as Mr. Smiles, now wearing a festive hat, juggled three oranges for Oliver and made him laugh.

“What the hell is going on?” I muttered, opening my car door.

Anger and confusion pushed me toward the house. The night air felt thick and heavy as I walked up the sidewalk. I barged in through the front door, causing everyone to freeze in mid-conversation, the cheerful music cutting off suddenly.

“Okay, you won,” I said, my voice shaking. “Everyone knew about this, right? Even Oliver? Even my sister?”

“No, no, please, stop!” Laura’s face turned pale, her hands clutching a roll of streamers that fell to the floor.

I turned to Mr. Smiles, who had stopped juggling and was now looking at me with wide eyes.

“You’ve disrespected me as a man, and you have no place here. This is my house! This is my…!”

My voice trailed off when I saw something shiny on the floor.

A banner, still unhung, with golden letters that read, “Happy 10th Anniversary!” The metallic paper reflected the light from the lamps, casting flashes on the ceiling.

The room fell into complete silence. Laura’s hands covered her mouth, tears pouring from her eyes, wiping away her carefully applied makeup. Mr. Smiles cleared his throat and stepped forward, his professional demeanor unshaken.

“Sir, I believe there’s been a misunderstanding,” he said softly. “I’m a wedding planner and party entertainer. Your wife hired me months ago to organize this event — your wedding anniversary!”

“Did you think I was cheating?” Laura’s voice cracked with disbelief, each word falling like a stone between us.

I felt the ground shift beneath me. The room suddenly seemed too bright, too full, the decorations out of place and mocking.

“I… I didn’t know what to think,” I stammered, my shirt collar too tight. “I saw him arrive here, and Oliver said a man kept coming when I was at work, that this man made you laugh…”

“Oliver said I made him laugh because I do magic tricks for him when we plan,” Laura interrupted, her voice rising. “I was trying to do something special for you, and you thought I was cheating?”

My throat tightened. “I’m sorry,” I managed to say, the words feeling insufficient. “I was wrong. I let my insecurities take over.”

Laura wiped her eyes with the back of her hand, leaving a dark smear of mascara. “How could you think that? After everything we’ve been through?”

The guests began to leave silently, murmuring strange goodbyes as their shoes scraped across the carpet.

My sister gave my shoulder a squeeze as she left, whispering, “Fix this.” Oliver seemed confused and scared, so Laura’s mother took him upstairs while their footsteps echoed in the tense silence.

Finally, when we were alone, Laura sat on the couch, her shoulders slumped. The streamers were tangled at her feet.

“I thought you knew everything,” she whispered.
