After Grant died, Audrey tried to protect her adopted daughter from the truth about his affair.

"Call the police," I said. "Right now. Don't open the door. Don't let her in. I'm on my way."

I hung up and floored the gas pedal.

Lena looked at me, her face white.

"What's wrong?"

"Margaret is at the house," I said. "She's trying to get to Poppy."

We drove as fast as we could.

When we turned onto my street, I saw Margaret's car parked in the driveway. She was standing on the front porch, banging on the door, screaming.

Sarah was inside with Poppy. Safe. For now.

I pulled into the street and parked.

"Stay in the car," I said to Lena. "Lock the doors. Call the police again if you have to."

I got out and walked toward the house.

Margaret heard me coming. She turned around.

Her face was twisted with rage.

"Where is she?" she screamed. "Where is that little traitor? I know she's with you!"

"Get off my property, Margaret," I said. "The police are on their way."

Margaret laughed. A wild, crazy sound.

"The police? You think the police can help you? You think I'm going to let you destroy everything I've built? Everything my son built?"

She took a step toward me.

"You think you can just take what's mine? The evidence? The baby? My granddaughter?"

She was close now. Too close. I could see the madness in her eyes.

"Poppy is not your granddaughter anymore," she spat. "Not when there's a real Bennett heir on the way. You think I'm going to let that adopted little girl inherit what belongs to my grandson?"

Her words cut through me like a knife.

But I stood my ground.

"Poppy is my daughter," I said. "And she is more a Bennett than you will ever be."

Margaret screamed and lunged at me.

I stepped back, but she was fast. Her hands grabbed my arms, her nails digging into my skin.

"You ruined everything!" she screamed. "If Grant had just listened to me, if he had just married someone proper, none of this would have happened! He had to go and marry you. And then adopt that little brat. And then get that girl pregnant. He ruined everything!"

I struggled against her, but she was strong. Stronger than she looked.

"He was going to turn me in!" she screamed. "My own son! He was going to send his own mother to prison! What was I supposed to do? Just let him?"

My heart stopped.

"What did you do?" I whispered.

Margaret laughed. Her eyes were wild.

"I fixed his brakes," she said, her voice low and calm now. "Just a little. Enough so they would fail on that sharp curve on his way to work. It looked like an accident. Everyone believed it. Everyone but you, apparently."

I stared at her.

She had admitted it.

She had killed Grant.

And then I heard the sirens.

Police cars rounded the corner, lights flashing, sirens wailing.

Margaret heard them too. She looked up, then back at me.

"You think you've won?" she said. "You think this is over? I'll get out. And when I do, I'll come back for you. And for that little girl. And for the baby. I'll take everything from you. Just like you took everything from me."

Two police officers ran up and pulled her off me.

She struggled and screamed as they handcuffed her.

"You'll regret this, Audrey! You'll all regret this!"

They led her to the police car and put her inside.

Detective Carter got out of another car and walked over to me.

"Did you hear that?" she said.

I nodded.

"Every word."
