Chapter 1

My husband had been on a business trip for three days when he posted an Instagram Story.

The photo showed a tiny, wrinkled hand gripping an adult finger.

The caption was just one line. [Nine pounds, two ounces. Welcome to the world, son.]

My mind went blank for two full seconds.

I never missed a single one of Eric Carter's posts. I thought he was in Silvercrest closing a deal. He'd told me the week was packed, too busy to even call.

I was about to comment "whose adorable baby is this?" when my thumb drifted down to the comments.

The first one came from his coworker, Kevin Lewis.

Kevin: [Congrats, man! Your wife's a champ!]

Your wife's a champ. I sat on our living room couch with a warm mug of coffee between my palms, staring at those four words.

I wasn't pregnant. I hadn't given birth.

Just last month, I'd gone in for a preconception checkup. The doctor told me everything looked good and I was cleared to start trying.

Eric had said we'd start once he wrapped up this project. By the end of the year, he'd promised.

I went back and read the Story again.

He'd posted it to his Close Friends only. The fact that I could see it at all meant he'd either included me on the list, or he'd simply forgotten to block me.

*****

The comments kept rolling in. The second one came from Eric's buddy, Leo Jackson.

Leo: [Holy shit, dude! That was fast. Last time we grabbed drinks, you said Laura was only five months along. She already had the baby?]

I stared at the name "Laura" until my vision blurred.

Leo had posted a follow-up right below it. [Does your wife know yet? Last time you said you hadn't figured out how to break it to her.]

That comment disappeared less than 30 seconds after it went up. But I'd already taken a screenshot.

The coffee mug met the counter. My hands were perfectly steady. I saved the screenshot to my favorites, backed out of the app, and locked the screen.

The living room was quiet. On the TV, some dating show droned on in the background. One of the women was telling the host that her number one requirement in a partner was loyalty. I turned it off.

I picked up my phone and scrolled back through my texts with Eric.

His last message had come at 11 the night before. [Busy. Get some sleep.]

I'd replied: [Okay. Take care of yourself.]

I scrolled further back to the day he'd left, three days ago.

Eric: [Made it. Hotel's pretty nice.] He'd attached a photo of a hotel bed.

Looking at that photo now, I noticed a pink water bottle on the nightstand. Eric didn't own a pink water bottle. I screenshotted that one too.

Then I opened his Instagram profile and started scrolling backward.

Last month, he'd posted a photo from a steakhouse with the caption [Rare night off.]

That night, I'd worked late until nine. When I got home, he'd told me he grabbed dinner with Leo and was already back.

In the photo, two place settings faced each other across the table. Next to one of them sat a fruity cocktail with a tiny paper umbrella.

Leo didn't drink cocktails. Leo finished his beer and moved straight to Coke. He'd said it a thousand times.

I kept scrolling.

Two months back, Eric had posted a gym selfie. In the mirror behind him, I could make out a woman's silhouette with a ponytail and white yoga pants.

I scrolled further back through three months, then four, then six.

The clues surfaced one by one, like water seeping through a crack in a wall. Once you noticed the first drop, the whole surface was already stained.

I sat on that couch for 40 minutes straight. Then I stood up, walked to the bedroom, opened the closet, and pulled out a suitcase. Not because I was packing to leave.

I dug through the bottom of the case and pulled out a manila envelope I'd buried there years ago.

Inside were documents. Three years earlier, when I'd cut ties with my family and insisted on marrying Eric Carter, my father had his lawyer draw these up.

A prenuptial asset agreement, an equity trust agreement, and an unsigned board appointment letter from the Sullivan Group.

I laid them out on the bed, one by one, and read through every page.

Then I picked up my phone and dialed a number I hadn't called in three years. It rang twice.

"Nina?" The voice on the other end had aged, but the tone was exactly the same as three years ago. That was my father, Richard Sullivan, founder and chairman of the Sullivan Group.

"Dad."

Five seconds of silence passed between us.

"Finally come around?"

"No," I said. "I need a lawyer. For a divorce."

Three more seconds of silence stretched between us.

"Someone will be there tomorrow." He hung up.

Perched on the edge of the bed, I stared at my name on that board appointment letter.

I was Nina Sullivan, daughter of Richard Sullivan, founder of the Sullivan Group.

Eric had been married to me for three years without the faintest clue who his father-in-law was.

All he knew was that my parents lived out of state, I was an only child from a modest family, and my job was nothing special. Because that was exactly what I'd told him.
