Chapter 1

For three years of marriage, Julian never let me touch his briefcase.

I didn't care. He was a senior forensic auditor. I understood the need for confidentiality.

Until the day he went on a business trip and forgot it, asking me to overnight it to his hotel.

The zipper wasn't fully closed. A manila envelope slid out.

It was a custody agreement.

Party A: Julian Vance. Party B: Hailey.

The child's birth date: March 2021.

Julian and I got our marriage certificate in July 2021.

I knelt on the floor, doing the math. It didn't take long to figure out.

When that child was conceived, Julian and I were at the bridal studio, picking out photos for our wedding album.

I stuffed the envelope back in. I mailed the briefcase as if nothing had happened.

That night, he called to ask if I’d eaten.

I said yes.

Then he told me he’d bring back those gourmet lavender-lemon tarts I’d been dying to try from his trip next week.

I said okay.

After hanging up, I sat at the dining table for a long time.

Two sets of plates. A habit I had set for three years.

Suddenly, a memory clicked—

Every time he went on a business trip, he packed a tube of kids' toothpaste in his suitcase.

I had asked him about it once.

He said the hotel toothpaste was too strong, and he hated it.

A thirty-two-year-old man, using strawberry-flavored kids' toothpaste.

And I had believed him for three years.

"Chloe, did you get the briefcase? The front desk signed for it."

The next morning, Julian’s call woke me up right on time.

"Yes, I did."

"Great. What are your plans for today?"

"Nothing much. Just staying home."

"There are ribs in the fridge. I marinated them before I left. Put them in the instant pot for twenty minutes. Don't forget to add two pieces of rock sugar."

He mapped out every step of dinner for me, just like he had for the past three years. Precise. Meticulous. Just like his audit working papers.

"Got it."

After hanging up, I didn't go to the kitchen.

I logged into our resident portal and downloaded the monthly water bills. Kneeling on the bathroom floor, I took screenshots of the data, month by month, going back three years.

For a couple, our water usage was stable at around eight to ten tons a month.

When he was away on business, the usage should have dropped to about five tons, assuming one less person was showering and cooking.

But during his trip last November, the number was 0.3.

It hadn't dropped by half. It was practically zero.

I was in this apartment every day. I showered, cooked, and ran the laundry.

0.3 tons was barely enough to flush the toilet twice.

The pattern repeated for other months. Whenever he "traveled," the water usage plummeted. But it wasn't ridiculously low every single time, which meant some months he actually did leave the city.

Some months.

But not all of them.

That afternoon, I went to the bank.

The teller glanced at my ID. "How far back do you want the statements?"

"Three years."

"Three years?" She looked up at me. "That’s going to be a lot of pages. You’ll have to wait a bit."

"I'm not in a rush."

It came out to twenty-three pages of paper.

I didn't look through them at the bank. I rolled them up, shoved them into my bag, and went home. I spread them across the dining table, going through them line by line.

Most of the expenses were normal. Gas stations, supermarkets, utilities. Occasional Venmo transfers to me with notes like "Thanks, babe."

But on the 15th of every month, there was a fixed transfer. The amount varied between $800 and $1,200, always to the same account.

The note was always just one word: *Expenses.*

Not "child support," not "reimbursement," not any keyword that could be easily traced.

Just *Expenses.* Clean, like a cleared secondary ledger.

Another pattern was even more obvious—a quarterly charge at a baby boutique chain.

The earliest one was in April 2021. The child on that custody agreement was exactly one month old then.

Baby formula. Diapers. Wipes.

Later, the formula disappeared. It was replaced by baby cereal, then toddler snacks, and teething biscuits.

Then came the shoes. The first purchase was a toddler size 5. Then 6, 7, 8, 9.

The most recent one, just last month. Size 10.

A child growing from birth to a size 10 shoe, compressed into twenty-three pages of bank statements, hidden behind quarterly receipts of a few hundred dollars.

I highlighted these entries one by one. The neon yellow lines slashed through the paper, dense and crowded, like a series of fresh cuts.

Julian called at nine that night.

"Did you make the ribs?"

"Yes. I added the rock sugar."

I hadn't. The instant ramen cup was still in the trash.

"Were they good?"

"Yeah."

"Tomorrow you should try the tomato one—"

"Julian."

"Yeah?"

"There's a monthly transfer on your card on the 15th. It just says 'Expenses.' What is that?"

Silence for two seconds.

"Oh, that. I’m helping Zach out. He always forgets to pay his share of the team dinners on projects, so I just cover him first."

"For three years?"

"Yeah, he's a great guy, but he's terrible with small change." He laughed lightly. "Since when do you audit my accounts? Getting jealous?"

"I just stumbled across it."

"Alright, I'll ask him to settle it all at once next time." His voice was relaxed. "Don't overthink it, Chloe. You’re not that kind of person."

What kind of person was I?

"Yeah. I won't."

"Go to sleep early. Talk tomorrow."

He hung up.

I added two lines to my Notes app. *Audit Finding 1: Water usage during business trips is abnormally low. Audit Finding 2: Systematic fixed transfers and baby store expenses on the secondary card, spanning thirty-six months. The auditee's verbal explanation does not match the expense categories.*

My phone buzzed again.

He sent a photo. On the hotel nightstand stood a tube of pink toothpaste with a cartoon strawberry on it.

His caption: *See? I remembered to pack it.*

I stared at the photo for ten seconds.

I texted back three words.

*You're so good.*
