The slap broke one of Rebecca’s front teeth before they even realized...

The sound was dry, wet, and horrific.

Rebecca didn’t feel the pain right away. She felt her body spin. She felt Emma’s warm weight shift against her chest. She felt one of her knees hit the carpet, right next to the light blue sofa.

Then, something small and white fell near Emma’s sock.

A piece of a tooth.

Emma started screaming.

Rebecca’s hand flew to her mouth. Her tongue brushed against a sharp, jagged edge where, just a moment before, her front tooth had been. Blood spread across her palm and dripped onto the white maternity shirt she had bought on sale the week before.

Trevor had complained about that purchase. He said she didn’t need new clothes. He said she was getting fat anyway.

Now he stood over her, his open hand still raised, his face shadowed by a mixture of rage and confusion, as if he were the victim in that room.

“Look what you made me do.”

Rebecca looked up at him from below.

She was twenty-five weeks pregnant. She kept one arm wrapped around Emma, who was eighteen months old and sobbing so hard she could barely breathe. Rebecca’s other hand covered her abdomen.

The baby kicked. Hard. That movement brought her back to reality.

Trevor paced back and forth in front of them, running both hands through his hair. He was wearing the navy trousers and white shirt he had worn to work, but his tie was gone and the top buttons were undone.

“You wouldn’t stop,” he said. “I asked you for one simple thing. To keep Emma quiet while I finished the call.”

Emma had wanted a cookie before dinner. Rebecca had told her no. Emma cried.

Trevor had come out of his office, accusing Rebecca of deliberately humiliating him in front of a client. Rebecca told him that Emma was a toddler, not an employee. He told her she was useless. She asked him not to speak that way in front of their daughter.

And then his hand struck her face.

Rebecca should have been angry. Yet, her first thought was one of relief. Thank goodness the neighbors are too far away to hear this.

Still bleeding, she was still protecting him.

Emma touched Rebecca’s cheek with both of her tiny hands. “Mommy. Mommy.”

“Shh, my love,” Rebecca whispered through the blood. “Mommy’s still here.”

The words came out slurred.

Trevor stopped pacing. He looked at the blood on Rebecca’s shirt and then at the fragment of tooth on the carpet. Something resembling fear crossed his face, but it wasn’t fear for her. It was fear of the consequences.

“You have to clean that up.”

Rebecca looked toward her phone, which was near the sofa. Trevor noticed. “Don’t even think about it.”

She moved a hand slowly across the carpet.

Three loud knocks thundered at the front door. Trevor froze. Rebecca’s heart stopped with him.

A man’s voice came from outside. “Rebecca, open the door. It’s Dad.”

Richard.

Trevor turned to her. His expression changed so fast he seemed like a different man. The rage vanished. His mouth softened. His shoulders dropped. He transformed into the charming son-in-law who laughed at Richard’s jokes and asked interested questions about the stock market.

Then he saw Rebecca’s blood again. Panic returned. He rushed across the room and crouched beside her. His fingers closed around her wrist before she could reach the phone.

“Tell him you’re fine.”

Emma was crying against Rebecca’s shoulder. Trevor tightened his grip. “He can’t see you like this.”

Rebecca looked toward the door.

That morning, while Trevor was at work, she had called Richard from the parking lot of her gynecologist's office. She had been on the verge of hanging up when he answered. Instead, she asked him to come over at seven. She said she needed to talk. Richard asked if she and Emma were safe. Rebecca lied. “Yes.”

He sensed the lie. “I’ll be there at six-thirty,” he said.

Trevor knew nothing about the call. He thought Richard had shown up unannounced.

Rebecca had planned to tell her father about the bank accounts, the threats, and the way Trevor checked her phone while she slept. She hadn’t planned to tell him about physical violence because, until thirty seconds ago, she still described Trevor as a man who had never hit her.

He had pushed her. He had blocked doorways. He had punched a closet right next to her head. He had driven too fast while she begged him to slow down. But he had never hit her.

That distinction now lay shattered on the carpet.

“Rebecca,” Richard called out. “Open the door.”

Trevor leaned in close enough for her to smell the coffee on his breath. “If you destroy this family, it will be your fault.”

Rebecca pulled her wrist free. She raised herself just enough to reach the deadbolt, holding Emma against her chest and avoiding putting weight on her trembling legs.

Trevor whispered, “Think carefully about what you’re going to do.”

Rebecca turned the lock. The door opened.

Richard stood outside, dressed in a dark suit, his graying hair illuminated by the porch light. Behind him, a black sedan waited at the curb with the driver inside.

Richard’s eyes shifted from Rebecca’s split lip to the blood on her shirt. Then he saw Emma. Then Trevor.

Rebecca had three seconds to protect her marriage or protect her children.

“Dad,” she said, “help us.”

Richard stepped inside. He didn’t hit Trevor. He didn’t shout. He placed himself between Trevor and Rebecca, pulled out his phone, and dialed emergency services.

Trevor’s face collapsed. “This isn’t what it looks like.”

Richard looked at the tooth fragment on the carpet. “It looks like my daughter needs an ambulance.”

“It was an accident.”

Behind Richard, Rebecca began to shake so violently that Emma slipped against her shoulder. Richard turned halfway, keeping his eye on Trevor.

“Sit down, Rebecca.”

“I can’t.”

“You can. I’m here.”

Those words should have comforted her. Instead, they reminded her of how long she had been waiting for someone to tell her what she had permission to do.

In the distance, sirens blared. Trevor glanced toward the back hallway. Richard caught it.

“Don’t move.”

“You don’t order me around.”

“No,” Richard said. “But the police are going to want to talk to you.”

Trevor’s eyes locked onto Rebecca. The hatred in them was quiet now. “You called him before this happened.”
