The first time my stepson called my toddler a thief, he wasn't talking about toys.

The hallway carpet muffled my footsteps, but my heart was beating so hard against my ribs that I was certain Oliver could hear it through the drywall.

I set the laundry basket down against the baseboard. Slowly, inch by inch, I drew closer to his slightly open bedroom door. The white paint was chipped near the knob where Oliver had bumped it with his scooter three summers ago. Through the three-inch gap, a strip of midday sun cut across the gray floorboards.

Oliver was sitting on the edge of his unmade bed, his knees drawn up to his chest, his forehead resting against his shins. His shoulders hitched with silent, shuddering sobs. He was holding something small and rectangular in his right hand.

Then he spoke again.

"I tried, Mom," he whispered into the phone. His voice was ragged, choked with the kind of misery that didn't belong in a nine-year-old child. "I did what you said. I told him. But he just... he protected her. He didn't even look at me."

A pause. Oliver listened, the screen pressed tightly against his ear.

"No," Oliver whimpered, pulling his knees tighter. "He didn't hit me. He told me to go to my room. He picked her up first. He always picks her up first."

Another silence followed, stretched thin by the muffled, tinny sound of a woman’s voice spilling through the speaker. I couldn't make out the exact words, but the sharp, rapid cadence was unmistakable.

It was Nadia.

"Are you sure?" Oliver asked, his breath hitching. "Are you sure the papers are already signed? Can't he change his mind if I'm better? If I clean my room and stop asking for baseball stuff?"

My stomach dropped into a cold, bottomless void.

*Papers? What papers?*

Oliver’s hand shook so violently that the phone slipped against his cheek. "I don't want to go to boarding school, Mom. You said if he had a new baby, he’d send me away to that school in Maine. Please don't let him send me away. Can't I just come live with you full-time? You promised."

He began to cry harder, pressing the heel of his palm into his eyes. "Okay... okay. I won't tell him you told me. I promise. I love you too."

The line went dead.

Oliver dropped the phone onto his quilt. It wasn’t his regular tablet—the one Paul and I monitored with parental controls. It was a cheap, black prepaid flip phone, wrapped in green electrical tape around the hinge.

He didn't move. He just sat there, small and hunched under his solar-system poster, staring at his sneakers.

I leaned my back against the hallway wall, my hands trembling. The air in my lungs tasted like copper.

*Boarding school in Maine? Papers already signed?*

Paul worked fifty hours a week fixing boiler lines and surgical air filtration systems at Highland Hospital. We clipped coupons to afford Oliver’s Little League registration and Ellie’s pediatric dental visits. We didn't have the money for a boarding school in Maine even if we wanted one—which we never, in a million lifetimes, would.

Paul adored Oliver. When Oliver had pneumonia at age six, Paul had slept on two metal folding chairs pushed together in the hospital room for four nights straight, refusing to leave his side.

Someone had planted poison in this child’s mind. And that someone was his biological mother.

I took a deep, steadying breath. I couldn't storm in there like a hurricane. If Oliver realized I had overheard, he would retreat further into the shell Nadia had built around him.

I tapped lightly on the open wood of the door. "Oliver?"

He flinched violently. In a single, panicked motion, he shoved the prepaid phone under his pillow and wiped his face with the sleeve of his gray hoodie.

"Yeah?" His voice cracked, rough and defensive.

I stepped into the room, keeping my hands visible, my shoulders relaxed, trying to look like nothing more than an extra grown-up offering clean towels.

"Can I come in for a minute, bud?"

"Dad told me to stay here."

"I know. But I wanted to make sure you were okay."

"I'm fine," he muttered, staring resolutely at the floor. "You should go check on Ellie. That's what you care about."

The barb stung, but I refused to let it show. I walked over and sat on the wooden desk chair near his bed, keeping enough distance so he wouldn't feel cornered. Up close, I could see the red rings around his eyes, the blotchy skin on his cheeks, and the absolute exhaustion etched into his features.

"Oliver," I said gently, "what happened downstairs was scary. For Ellie, for your dad, and for you."

"I didn't mean to flip the bowl," he whispered, his jaw clenching. "It just... it slipped."

"You said she stole your dad."

Oliver didn't answer. He picked at a loose thread on his comforter.

"Do you really think that?" I asked softly. "Do you think your dad doesn't have enough room in his heart for you and Ellie both?"

"Grown-ups always say there's room," Oliver said, his voice flat, devoid of the innocence he had carried just six months ago. "But there isn't. When someone new comes, the old thing gets thrown away."

"Who told you that, Oliver?"

He froze. His eyes flicked nervously toward the pillow where the black phone was hidden. "Nobody. I just know. I see it."

"You don't see that from your dad," I said firmly, but with warmth. "Who spent two hours in the cold last Tuesday helping you adjust your batting stance? Who makes sure your hot chocolate has exactly seven mini-marshmallows every single Friday night?"

Oliver’s lower lip trembled, but then a shadow crossed his face—a defensive, adult cynicism that broke my heart. "He's just doing that because he feels guilty."

"Guilty about what?"

"Nothing." Oliver turned his body completely away from me, facing the wall. "Leave me alone, Lena. Please."

I sat in the silence for another ten seconds, listening to the ticking of the clock shaped like a baseball on his dresser.

"I'm leaving the door open," I said softly, standing up. "Your dad loves you more than his own life, Oliver. Nothing and no one will ever change that. Not Ellie. Not me. Not anyone."

He didn't turn around.

I walked out of his room, left the towels on the hall table, and walked straight down the stairs.

Paul was standing at the sink, rinsing the last dried flecks of oatmeal from Ellie’s plastic bowl. His broad shoulders were slumped, his graying hair uncombed.

I didn't say a word. I walked up behind him, wrapped my arms around his waist, and pressed my forehead against his shoulder blade.

He stiffened in surprise, then let out a long, shuddering sigh, setting the sponge down. He turned around in my arms and pulled me close.

"I'm sorry, Lena," he murmured into my hair. "I don't know what I did wrong. I thought things were getting better. He was so happy last summer. Now it feels like he looks at me and sees an enemy."

I pulled back just enough to look directly into his hazel eyes.

"Paul," I said, my voice low and dead serious. "We have a massive problem. Oliver has a secret phone."

Paul blinked, confused. "What? What are you talking about?"

"I heard him on it just now. In his room." I gripped his forearms. "He was talking to Nadia. And she has convinced that little boy that you are signing papers to send him away to a boarding school in Maine because you have Ellie now."

Paul’s face went entirely white.
