I stayed at Rachel’s house while the police searched.

Sophie did not need to watch strangers pull apart the hallway where her mother died. I did not need to be there to tell them what to find.

At noon, Detective Moreno called.

“We found a brass key beneath the radiator.”

I gripped the kitchen counter.

“Was Sophie right about where it fell?”

“Yes.”

The detective said there was a small numbered tag attached. They were working out what it opened. She promised to call when she knew more.

I went into the living room. Sophie and Rachel were making paper birds. My daughter had folded one wing much longer than the other. She held it up and waited for me to look.

“It looks ready to fly,” I said.

She pointed at the uneven wing and gave me a look Grace used to give me whenever I tried too hard to be kind.

“All right,” I said. “It needs some help.”

She let me fold the wing again.

The key opened a storage box at Grace’s charity office. Mrs. Bell knew the number as soon as Detective Moreno read it. Grace had rented the box to hold event supplies and old records.

Elena, my attorney, went with the detectives when they opened it. I waited for her call at Rachel’s.

Grace had placed copies of the questionable invoices inside, along with notes from a meeting she had held with Vanessa. She had written down Vanessa’s explanation for the payments and the questions she intended to ask the events company.

There was also a dated letter addressed to me.

Elena brought me a copy that evening.

I sat alone in Rachel’s study to read it.

Grace had written that she did not want to accuse Vanessa until she was sure. She knew Vanessa and I had grown closer as friends while Grace was busy with the charity, but she trusted us both. The numbers frightened her because the charity served families who counted on every dollar.

If I am wrong, she wrote, we will correct it together. If I am right, I need you beside me when I tell the board.

I read that sentence several times.

The day she died, I had been at work. She had called and asked me to come home. I had said I would. I arrived too late.

I folded the letter and went outside. Marisol was on the porch, waiting for Eli to finish his visit with Sophie.

“She wanted me beside her,” I said.

Marisol looked at the paper in my hand.

“You came when she called.”

“After I finished a meeting.”

“You didn’t know what was happening.”

“I knew she sounded worried.”

Marisol did not try to talk me out of my grief.

“Grace believed you would listen,” she said. “You can show Sophie she was right.”

Inside, Eli was packing his cards. He asked whether Sophie could visit the community garden with him when it reopened. Marisol had taken a new job there after returning to town.

Sophie nodded so hard her hair fell into her eyes.

“We’ll ask Dr. Patel what would help her feel comfortable,” I said. “Then we can plan it.”

I had once filled Sophie’s days with appointments because I thought each one might bring her voice back. Now I wanted her to have a day among plants and friends.

The following week brought news I could not share with her yet. Investigators found bank records linking Vanessa to the events company. They also found messages showing Grace had confronted her about the invoices. Vanessa had replied that she would explain everything that evening.

Detective Moreno asked me to come to her office. Elena joined us.

“Vanessa says Grace lost her balance during an argument,” the detective said. “She admits she was near the stairs.”

I stared at her.

“She told the police she wasn’t there.”

“Yes.”

“Why is she changing her story?”

“I can’t speak for her. We have the children’s accounts, the camera work order, the key, and Grace’s records. Her earlier statement conflicts with what we’ve established.”

I asked whether Vanessa had pushed Grace.

“We’re still investigating that. She says she didn’t touch her.”

When I left the office, I drove to a quiet parking lot before calling Rachel. I could not bear the thought of arriving at her house angry and letting Sophie think my anger was for her.

Rachel answered on the first ring.

“She’s with Ruth,” she said. “They’re baking.”

“Vanessa admits she was near the stairs.”

Rachel made a small sound.

“Come home when you can,” she said. “I’ll keep them busy.”

Home. For the moment, Rachel’s house was home.

When I arrived, Sophie had flour on her nose. Ruth held out a spoonful of dough for me to taste. I stayed in the kitchen until the first tray came out of the oven.

At bedtime, Sophie asked for Grace’s letter. I had told her I had found something her mother wrote, but I had not read it to her yet. Some of it was about money and fear. I chose the last lines.

“Your mom wrote that she loved you,” I said. “She wanted the garden to keep growing, and she was looking forward to showing you the spring flowers.”

Sophie took the page carefully.

“Was she scared?” she asked.

“Yes,” I said. “She was trying to solve a problem.”

Sophie looked at me for a long time.

“I was scared too.”

“I know.”

“I thought Vanessa would be angry if I told.”

“She may have been. That was for the adults to handle. You did nothing wrong.”

Sophie leaned into my shoulder. I held her while she cried.
