That’s one thing he’s better off not knowing.

I never intended to paint this way. In art school, I was drawn to simplicity in both color and form. Andy Warhol’s soup cans. Jasper Johns’s flags. Piet Mondrian’s bold squares and rigid black lines. Then came an assignment to paint a portrait of someone I knew who had died.

I chose the girls.

I painted Vivian first, because she burned brightest in my memory. That blond hair right out of a shampoo ad. Those incongruously dark eyes that looked black in the right light. The pert nose sprayed with freckles brought out by the sun. I put her in a white dress with an elaborate Victorian collar fanning around her swanlike neck and gave her the same enigmatic smile she displayed on her way out of the cabin.

You’re too young for this, Em.

Natalie came next. High forehead. Square chin. Hair pulled tight in a ponytail. Her white dress got a dainty lace collar that downplayed her thick neck and broad shoulders.

Finally, there was Allison, with her wholesome look. Apple cheeks and slender nose. Brows two shades darker than her flaxen hair, so thin and perfect they looked like they had been drawn on with brown pencil. I painted an Elizabethan ruff around her neck, frilly and regal.

Yet there was something wrong with the finished painting. Something that gnawed at me until the night before the project was due, when I awoke at 2:00 a.m. and saw the three of them staring at me from across the room.

Seeing them. That was the problem.

I crept out of bed and approached the canvas. I grabbed a brush, dabbed it in some brown paint, and smeared a line over their eyes. A tree branch, blinding them. More branches followed. Then plants and vines and whole trees, all of them gliding off the brush onto the canvas, as if sprouting there. By dawn, most of the canvas had been besieged by forest. All that remained of Vivian, Natalie, and Allison were shreds of their white dresses, patches of skin, locks of hair.

That became No. 1. The first in my forest series. The only one where even a fraction of the girls is visible. That piece, which got the highest grade in the class after I explained its meaning to my instructor, is absent from the gallery show. It hangs in my loft, not for sale.

Most of the others are here, though, with each painting taking up a full wall of the multichambered gallery. Seeing them together like this, with their gnarled branches and vibrant leaves, makes me realize how obsessive the whole endeavor is. Knowing I’ve spent years painting the same subject unnerves me.

“I am proud,” I tell Marc before taking a sip of champagne.

He downs his glass in one gulp and grabs a fresh one. “Then what’s up? You seem vexed.”

He says it with a reedy British accent, a dead-on impersonation of Vincent Price in that campy horror movie neither of us can remember the name of. All we know is that we were stoned when we watched it on TV one night, and the line made us howl with laughter. We say it to each other far too often.

“It’s just weird. All of this.” I use my champagne flute to gesture at the paintings dominating the walls, the people lined up in front of them, Randall kissing both cheeks of a svelte European couple who just walked through the door. “I never expected any of this.”

I’m not being humble. It’s the truth. If I had expected a gallery show, I would have actually named my work. Instead, I simply numbered them in the order they were painted. No. 1 through No. 33.

Randall, the gallery, this surreal opening reception—all of it is a happy accident. The product of being in the right place at the right time. That right place, incidentally, was Marc’s bistro in the West Village. At the time, I was in my fourth year of being the in-house artist at an ad agency. It was neither enjoyable nor fulfilling, but it paid the rent on a crumbling loft big enough to fit my forest canvases. After an overhead pipe leaked into the bistro, Marc needed something to temporarily mask a wall’s worth of water damage. I loaned him No. 8 because it was the biggest and able to cover the most square footage.

That right time was a week later, when the owner of a small gallery a few blocks away popped into Marc’s place for lunch. He saw the painting, was suitably intrigued, and asked Marc about the artist.

That led to one of my paintings—No. 7—being displayed in the gallery. It sold within a week. The owner asked for more. I gave him three. One of the paintings—lucky No. 13—caught the eye of a young art lover who posted a picture of it on Instagram. That picture was noticed by her employer, a television actress known for setting trends. She bought the painting and hung it in her dining room, showing it off during a dinner party for a small group of friends. One of those friends, an editor at Vogue, told his cousin, the owner of a larger, more prestigious gallery. That cousin is Randall, who currently roams the gallery, coiling his arms around every guest he sees.

What none of them knows—not Randall, not the actress, not even Marc—is that those thirty-three canvases are the only things I’ve painted outside my duties at the ad agency. There are no fresh ideas percolating in this artist’s brain, no inspiration sparking me into productivity. I’ve attempted other things, of course, more from a nagging sense of responsibility than actual desire. But I’m never able to move beyond those initial, halfhearted efforts. I return to the girls every damn time.

I know I can’t keep painting them, losing them in the woods again and again. To that end, I’ve vowed not to paint another. There won’t be a No. 34 or a No. 46 or, God forbid, a No. 112.
