“Because Audrey gave them Logan’s schedule, and she told them where he kept the file.”

I read it twice. The words didn’t change.

Mr. Vance was still beside the desk. I could hear the old wall clock ticking, which seemed silly to remember now, but it was loud enough that I kept waiting for it to stop.

“Who are ‘them’?” I asked.

“I don’t know,” he said. “Logan never gave me a name.”

That wasn’t enough. Not even close.

I kept reading. Logan wrote that he’d been looking into payments made to a vendor called Northline Services.

The company did work for his employer, and the payments didn’t match the work on the invoices. Logan had found bank transfers going through a second company, then ending up in accounts held by people he knew.

One name was Audrey’s.

I looked up at Mr. Vance. He didn’t try to take the letter from me or explain it away. He just said Logan had shown him copies of the records the week before the crash.

“Did you know about Audrey?” I asked.

“I knew her name was in the records,” he said. “I didn’t know what it meant.”

The letter didn’t say she had caused the crash. It said she’d been paid to pass along information. Logan wrote that he thought she’d told someone when he was leaving work and what he planned to bring home. He also wrote that he couldn’t tell if she understood what she was helping with.

That part made me angry. I wanted a clean answer. I wanted him to say Audrey had planned it, or that she’d been tricked, anything I could hold on to without having to think about all the years we’d been sisters.

There was more. Logan had asked Audrey about the payments, and she’d said she needed the money. He’d told her he was going to report the fraud. She had asked him to wait.

Then he wrote, “She said she only gave them my schedule.”

I put the letter down.

“Did you know Logan was looking into this?” I asked Mr. Vance.

“Not until he brought me the records.”

“Why didn’t you tell the police?”

“I did,” he said. “They asked about his work. I told them what I knew.”

I looked at the envelope, then at the photo of Logan and the kids on his desk. In the picture, our son had frosting on his chin.

Logan had taken it on his phone and made me print it because he said we never had pictures that weren’t blurry.

I hated that I was sitting in his office trying to decide whether his sister-in-law had helped get him killed.

Mr. Vance said he’d called me because Logan had told him to make sure I got the file if anything happened. He hadn’t wanted the company’s lawyers to get to it first. I asked if he had copies.

“I kept one set,” he said. “I can give it to the police.”

“Then we’re going together.”

He nodded. He didn’t tell me to calm down. I was glad he didn’t.

The papers were not all as clear as the letter. Some were photocopies, some were printouts with handwritten notes in Logan’s small, neat writing. The bank statements showed payments from Northline to an account in Audrey’s name. The dates went back several months.

I recognized one of them because it was the week she’d told me she was short on rent.

There were photographs, too. Logan had taken pictures of a company parking lot and a building with Northline’s name on a side door. In one, a man was carrying a box from the building to a car. I didn’t know him. In another, Audrey was standing near the back entrance, holding her phone up.

I almost called her right there. My thumb was on her name before I stopped myself.

Mr. Vance said we shouldn’t decide what the pictures meant on our own. He was right, which made me mad at him for a minute.

So I put the phone down.

We went to the Boston police station that afternoon. I told them the police in Worcester had called the crash an accident, but Logan’s letter and the records made me doubt that. They took the envelope and made a list of what was inside. I asked for a receipt. I kept the receipt in my wallet, because I didn’t trust myself to remember anything else.

The officer didn’t promise me they’d solve it. She said the new information would be sent to the right people and the crash report could be reviewed. She also said she couldn’t tell me what would happen with Audrey.

I asked if she could call her. The officer said they would decide who to interview and when.

I didn’t like that answer. I gave her the file anyway.

When I got home, Audrey was in my kitchen with my daughter, helping her make toast. She’d been watching the kids while I went to Boston. I’d asked her to. I’d trusted her enough to leave them with her and driven away with a letter saying she had given people Logan’s schedule.

My daughter was laughing at something Audrey had said. The toaster smelled like burnt bread. It was a regular afternoon. That made it worse.

Audrey took one look at me and said, “What happened?”

I told her I’d gone to the police.

She didn’t ask why. She didn’t ask what I’d found. She just put the butter knife down on the counter.

“Did you show them the file?” she asked.

“Yes.”

She looked at me then, and I knew she had already understood what the question would be.

I sent the kids to the living room. I told them I needed to talk to Aunt Audrey. My daughter asked if she’d done something wrong. I said no, though I didn’t know if that was true.

When the kids were out of the kitchen, I asked Audrey why her name was on the bank statements.

She rubbed her hands together. “I was helping with paperwork.”

“What paperwork?”

“I don’t know all of it.”

“You got paid.”

“I needed the money.”

“How much did you know about Logan?”

She looked down at the counter. “Clara, I didn’t know anyone was going to hurt him.”

That was the first thing she said that sounded like an answer.

I asked her if she had given someone his schedule. She said she’d sent a picture of his calendar to a man who told her he needed to confirm a meeting. She said she thought it was about the work, not about Logan going home.

“Who was the man?”

“I don’t know his real name.”

“You took money from him.”

“I know.”

“You told him where Logan kept the file?”

She shut her eyes for a second. “I told him Logan had copies at the office.”

That still wasn’t all the same thing. I was trying to separate what she had done from what she’d meant to do, and I hated myself for doing it. I’d spent most of my life making excuses for Audrey. She was always the one who had it harder, or needed more time, or didn’t mean it the way it sounded.

“Did you know Logan was in danger?” I asked.

“No.”

“Did he ask you about the money?”

“Yes.”

“And you lied to him?”

She started to cry then. Not loud. Just rubbed at her eyes with the side of one finger like she was annoyed they were wet.

“He said he’d go to the police,” she said. “I was scared. I thought if I could get the file first, I could make it stop.”

“You thought taking it would make this stop?”

“I thought they’d leave me alone.”

She said she hadn’t known anyone planned to hurt Logan. She said after the crash, the man who had paid her stopped answering her calls. She said she’d been afraid to tell me because she knew I’d ask where the money came from.

She also said she’d stayed by my side at the wake because she loved me.

I believed that part. I wished I didn’t.

I asked if she had called Logan the night he died. She said no. I told her I’d seen a note about a call from her on the records, and she corrected herself. She’d called him earlier that day, not that night. She’d wanted to ask about a bill.

“I forgot,” she said.

Maybe she had. Or maybe she was looking for a version that made her sound less involved. I couldn’t tell, and I didn’t have the strength to keep dragging truth out of her one piece at a time.

I told her not to come to my house again until I called her. She started to say my name, but I stopped her.

“Not now, Audrey.”

She looked toward the living room, where the kids were watching a cartoon. She asked if she could say goodbye to them. I said no. It came out harsher than I meant, but I didn’t take it back.

After she left, I stood at the sink and washed the butter knife she’d used. I don’t know why I did that. It wasn’t even dirty.

The next morning, Mr. Vance called to say the police had asked him to come in. He also told me Logan had been getting odd calls in the last few weeks before he died. Someone had asked for his schedule and said there was a problem with a vendor account. Logan hadn’t thought it was serious at first.

I asked why Mr. Vance hadn’t told me sooner.

“He didn’t tell me until the week he died,” he said. “I thought he was handling it through the company.”

“You let me think it was just a crash.”

“I believed it was an accident.”

He sounded tired, not defensive. I still wished he had told me the minute he called about the file. But he had given the papers to the police, and that mattered more than whether I liked him.

A detective called me two days later. She said Logan’s records gave them a reason to look at the crash again, but she couldn’t say whether it had been deliberate. She asked me not to contact Audrey about the investigation. I told her I already had.

The detective said she’d make a note of that. She didn’t scold me.

Audrey called me that evening. I let it ring. Then she called again. I picked up on the third try because I was worried she might be calling about the kids, though she knew they were fine.

“I’m sorry,” she said.

I was standing in the hallway with Logan’s old jacket hanging on the hook beside me. I’d kept wearing it around the house because it still smelled faintly like the soap we used. I thought I’d stopped noticing that smell. I hadn’t.

“I can’t take that from you right now,” I said.

“I didn’t mean for him to die.”

“I know you say that.”

“I loved him too.”

“I know.”

It was a long pause. I could hear her breathe, then try to stop herself from crying.

“I never told them where you lived,” she said.

I hadn’t asked. But the fact that she said it made me understand she’d considered it.

“Don’t call for a while,” I said.

“Clara, please.”

“I have to think about the kids.”

“I would never hurt them.”

“I’m not saying you would. I’m saying I can’t have you here.”

She said okay. Then she hung up.

The police interviewed Audrey. I didn’t hear the details from them. I only know she gave them her phone and agreed to speak with them again. They also contacted the company that owned Northline Services. Mr. Vance told me that much after I asked him not to keep me in the dark.

I didn’t get a neat answer about who had been on the other end of Audrey’s calls. I didn’t get proof that someone caused the crash. The police said the evidence had changed the direction of the investigation, not the conclusion. They were reviewing the car and the old records. That was all they could tell me.

For a while, I wanted them to tell me more. I wanted one name, one reason, one thing that would make the crash fit into a story I could understand.

Instead, I had a file receipt, a copy of Logan’s letter, and a sister I couldn’t trust with my children.

I made one more decision. I changed the locks, not because anyone told me Audrey would come back, but because I couldn’t sleep while the old key still worked. I told the school that only I could pick up the kids unless I called ahead. It felt mean to write that down. I did it anyway.

My daughter asked why Aunt Audrey wasn’t coming over. I said she had some things to sort out. My son asked if Dad would be home for his birthday. I said no. He asked if Dad knew about the cake he wanted, and I said I was sure he did.

That wasn’t true. But I couldn’t find a better answer that a five-year-old could carry.

The last time I went to Logan’s office, I brought the family photo home. The desk had been cleared by then. I stood there a while, holding the frame against my coat. I didn’t look for any other hidden papers. I didn’t want to find another reason to be afraid of someone I loved.

At home, I put the photo on the kitchen shelf where the kids could reach it. I put Logan’s letter in a folder with the police receipt and the copies Mr. Vance had kept. The brown envelope went in too. I did not throw it away.

On the front, in Logan’s handwriting, it still said, “For Clara.”

I closed the folder and put it where Audrey no longer had a key.
