The thing about crossing lines is that you never see them until you’re already on the other side.
Harper Montgomery sat in the corner of Brew Haven on a Monday morning, laptop open to a presentation she’d rewritten three times, double-shot espresso going cold beside her mouse. The marketing deck for her biggest client was due by noon, but she couldn’t focus. Hadn’t been able to focus for weeks, actually—not since she’d found the receipt.
Dinner for two at Marcello’s. The restaurant where her parents had their first date twenty-eight years ago.
Except her father had been in Chicago that night. Business trip, he’d said.
Harper’s fingers hovered over the keyboard, but the words blurred. All she could see was that receipt, tucked in his jacket pocket like he didn’t even care enough to hide it properly. Like after twenty-eight years of marriage, he’d stopped trying.
“Dude, I’m serious. My face is literally my fortune at this point.”
The voice cut through her spiraling thoughts—deep, warm, edged with humor that made it impossible not to listen. Harper glanced up.
Two guys at the next table. One she vaguely recognized—Logan something, did photography for local magazines. The other was new.
And unfairly attractive.
Bronze skin, dark hair that looked expensively messy in that way that probably took zero effort, a smile that could sell anything. He wore a leather jacket over a faded band tee, silver rings on three fingers, and had the kind of face that belonged on billboards. Or in trouble.
Definitely in trouble.
“You can’t actually be considering this,” Logan said, shaking his head. “Taking money to go on dates with lonely rich women? That’s—”
“Networking,” the attractive one—Mason, based on Logan calling his name twice—interrupted smoothly. “I’m networking. And yes, I’m considering it. Caleb’s tuition is due in two weeks and I’m about $500 short.”
Harper’s heart did something complicated in her chest.
Five. Hundred. Dollars.
“There are other ways to make money that don’t involve your face and someone’s desperate housewife fantasy,” Logan argued.
Mason laughed, low and unbothered. “Yeah? Name one that pays $500 for three hours and doesn’t require me to sell a kidney.”
Harper’s pulse kicked up. This was insane. Completely insane.
But the idea was already forming, sharp and reckless and absolutely unhinged.
Her mother’s charity gala was Friday. Black-tie event, silent auction, two hundred guests. Claire Montgomery in her element—elegant, gracious, the perfect corporate wife. And lately, so damn sad when she thought no one was looking.
If Dad was cheating—and that receipt plus the late nights and the constant phone calls he took in the other room strongly suggested he was—then maybe Mom was vulnerable. Maybe she was one charming conversation away from making her own bad decision.
Maybe Harper needed to know if her mother would cheat back.
God, she was a terrible person.
But she was also a person who needed the truth, no matter how ugly. Because watching her parents’ marriage crumble in slow motion while they both pretended everything was fine was killing her.
Better to know. Better to have proof before she confronted her father and blew up their family.
Better to test the waters first.
Harper closed her laptop. Picked up her coffee cup even though her hands were shaking.
This was crazy. This was crossing a line she couldn’t uncross.
She stood anyway.
Mason looked up when her shadow fell across their table, those dark eyes meeting hers with curiosity and something that made her stomach flip in a way she absolutely did not have time for.
“Hi,” Harper said, voice steadier than she felt. “This is going to sound insane, but I have a proposition for you.”
Logan’s eyebrows shot up. Mason’s smile went from curious to intrigued in half a second.
“I’m listening,” Mason said.
Harper pulled out the chair across from him, sitting before she could talk herself out of it. “I need you to attend an event with me. This Friday. Black-tie charity gala. Three hours, maybe four. You’d just need to be charming, make conversation, look good in a suit.”
“And the catch is?” Mason asked, leaning back in his chair, studying her with unsettling focus.
“No catch. I’ll pay you $500. Cash. Half upfront, half after.”
Something flickered in Mason’s expression—surprise, maybe, or suspicion. “You’re serious.”
“Dead serious.”
“Why?” His eyes narrowed slightly. “You could bring anyone to a gala. Why hire a stranger?”
Because I need you to talk to my mother and see if she’d be receptive to cheating on my father felt like way too much honesty for a coffee shop on a Monday morning.
“Because everyone I know will ask questions I don’t want to answer,” Harper said instead, which was at least partially true. “I need someone who can work a room, be charming, and disappear after without making it complicated.”
Logan made a noise that might have been a laugh or a warning. “This sounds sketchy as hell.”
“It’s not,” Harper said, looking directly at Mason. “It’s a legitimate event. My mother runs the charity. I’ll give you all the details, dress code, everything. You just show up, be yourself, and leave by ten.”
“Your mother runs it,” Mason repeated slowly. “So this is a family thing.”
“Yes.”
“And you need to hire someone to come with you because…?”
“Because I don’t have a boyfriend and I’m tired of my mother’s friends trying to set me up with their sons,” Harper lied smoothly. “This way, I bring someone impressive, deflect the matchmaking, and everyone’s happy.”
It was a good lie. Believable. The kind of thing that happened at society events all the time.
Mason studied her for a long moment, and Harper had the uncomfortable feeling he could see right through her.
“$500,” he said finally. “For three hours of being charming at a charity gala.”
“Yes.”
“What’s the dress code?”
“Black tie. I can arrange a rental if you don’t have a tux.”
“I can handle my own wardrobe.” Mason glanced at Logan, who was watching this entire exchange like it was a car crash in slow motion, then back to Harper. “You seem normal enough. Successful. Pretty. Why hire someone instead of asking a friend?”
The compliment slipped past her defenses before she could stop it, warming something in her chest she immediately shoved down.
“Because friends ask follow-up questions,” Harper said. “And I don’t want to answer them.”
Another pause. Then Mason held out his hand.
“Deal.”
His hand was warm, calloused, strong. Harper shook it quickly and pulled back before the touch could register as anything other than professional.
“I’ll text you the details,” she said, pulling out her phone. “What’s your number?”
Mason rattled it off. Harper typed it in, sent a quick message so he’d have hers.
“Friday. Seven PM. The address is in the text. Don’t be late.” She stood, gathering her things with hands that definitely weren’t shaking. “And Mason?”
“Yeah?”
“Wear the leather jacket when you arrive. Then change into the tux. My mother likes the artistic type.”
His smile was slow, devastating, and made her regret approximately ninety percent of this decision.
“You got it, boss.”
Harper left before she could do something stupid like explain the real plan or ask why someone who looked like that needed $500 badly enough to take a job from a stranger in a coffee shop.
She made it halfway down the block before her phone buzzed.
Sienna: I JUST GOT A GOOGLE ALERT FOR YOUR LOCATION AND SAW YOU SITTING WITH A RANDOM HOT GUY
Sienna: WHAT ARE YOU DOING
Sienna: HARPER MONTGOMERY ANSWER YOUR PHONE
Harper declined the call. Texted back:
Harper: Making a terrible decision. Tell you later.
Sienna: THIS IS HOW PEOPLE END UP ON DATELINE
Harper pocketed her phone and kept walking.
She’d just hired a stranger to flirt with her mother. To test whether Claire Montgomery—elegant, principled, devoted wife for twenty-eight years—would be receptive to male attention that wasn’t from her increasingly distant husband.
It was manipulative. Wrong. Possibly the worst thing she’d ever done.
But if her father was cheating, Harper needed to know if her mother was complicit in their sham marriage, or a victim in it.
She needed to know if there was anything left worth saving.
Even if finding out destroyed everything.
That night, Harper let herself into her parents’ house using the key she’d had since high school. Monday dinners had been tradition since she moved out—Claire’s way of making sure they stayed connected even as Harper built her own life.
“In the kitchen!” her mother called.
Harper found her pulling a roasted chicken from the oven, flour dusting her silk blouse, reading glasses perched on her nose. Claire Montgomery at fifty-two was still stunning—elegant bone structure, silver threading through black hair she refused to dye, the kind of effortless grace that came from old money and good breeding.
She looked tired.
“Smells amazing,” Harper said, kissing her mother’s cheek.
“Your father’s working late. Again.” Claire’s voice was light, but something brittle lived underneath it. “So it’s just us.”
“His loss.”
They set the table together in comfortable silence, the kind that came from years of this exact routine. But tonight, the silence felt heavier.
Harper was about to test her own mother. Was about to send a stranger to flirt with her, to see if she’d respond, if she’d—
“Harper, sweetheart, you’re gripping that fork like you want to stab someone.”
Harper looked down. Her knuckles were white.
“Sorry. Long day.”
Claire studied her with those sharp eyes that missed nothing. “Boy trouble?”
“No. Work stuff.”
A pause. Then: “You know you can talk to me about anything, right?”
The irony was so sharp it could cut.
“I know, Mom.”
They ate dinner. Talked about the gala, about Claire’s new artist acquisition at the gallery, about everything except the elephant in the room shaped like Richard Montgomery’s absence.
Harper left at nine. Sat in her car in the driveway and watched the light from the kitchen window.
At 9:47, her father’s car pulled into the garage.
At 9:53, Harper heard the voices.
She cracked her car window.
“I can’t keep doing this.” Her father’s voice, strained and unfamiliar.
“Then don’t.” Her mother’s response, quiet and devastated.
Silence.
The kind of silence that confirmed every fear Harper had spent months trying to ignore.
She drove home with tears on her face and Mason Rivers’ number burning a hole in her phone.
Friday couldn’t come fast enough.
