I took my sister’s laptop in for repair. The technician whispered: “You should see this before deciding whether to call 911.”

The file opened instantly. There was no greeting, no signature, no wasted sentence. Just a block of plain text in Lumi’s writing style—short paragraphs, all lowercase except when she was stressed.

if you’re reading this, it means someone else opened my laptop or i couldn’t explain in time. before you call the police, read everything. i’m not stalking anyone. i’ve been documenting a man who has been following me for four months. i copied files under names he would never expect me to use. flora. vicky. old places. safe places. if you panic, look at the metadata and read the notes folder.

My knees nearly gave out. Mason pulled a chair from behind the workbench and pushed it toward me. “Sit.” I sat.

He clicked into a folder called notes, and this time I forced myself to read instead of react. Inside were dated documents, screenshots, and photos of license plates. Lumi had written everything down with brutal precision. The first note began in March: a man in a gray Tacoma truck had been parking across from her apartment three nights a week. Then he had appeared near the co-working studio she used. Then outside the coffee shop where she met clients. He never approached her directly. He just watched.

At first she thought she was imagining it. Then she started documenting. The file names were misdirection. Flora’s red coat. Vicky’s running route. The daycare. The café. Every image that had horrified me had an explanation in the notes: possible witness, public camera angle, truck visible in reflection, same man appears in background, used familiar names so if he forced access he wouldn’t know what mattered.

Mason opened one image and zoomed in on the window reflection behind Flora. There it was—a man in a dark baseball cap standing near a pickup truck, half hidden, looking straight at Flora’s direction. In another shot of Vicky by the river, the truck appeared again in the distance, parked illegally by the loading zone.

None of these women were being targeted. Lumi was. I pressed a hand to my mouth. “Why didn’t she tell me?”

Mason didn’t answer because he couldn’t. I called Lumi immediately. Straight to voicemail. Then I called again. And again.

On the fourth try, she picked up, breathless. “Luke?”

“Where are you?”

A pause. “What?”

“Where are you, Lumi?”

She heard something in my voice because hers changed instantly. “At a client meeting. Why?”

“Are you alone?”

“No. I’m at a café on Burnside. Luke, what’s wrong?”

I closed my eyes in relief so intense it hurt. “Stay there. Do not leave. I’m coming.”

Another pause. “You opened the laptop.”

“Mason did. Lumi, why didn’t you tell me?”

Her silence lasted just long enough to confirm everything. “Because,” she said at last, voice shaking, “I thought if I said it out loud, it would become real.”

I drove across the city in rain so heavy the windshield wipers could barely keep up. Mason came with me—his suggestion, not mine. “If there’s enough on that computer to justify calling 911,” he said, grabbing his keys, “then you shouldn’t go alone.”

By the time we got to the café, Lumi was sitting in a back booth, pale and rigid, one hand wrapped around an untouched tea. She looked smaller than usual, despite being twenty-seven and stubborn enough to argue with tow truck drivers.

The moment she saw my face, she started crying.

I slid into the booth across from her. “How long?”

“Since February,” she whispered.

“Why didn’t you tell Vicky? Or me?”

“Because you’d both make me go to the police.”

“Yes,” I said. “Obviously.”

She laughed once through tears. “I know.”

Mason set the laptop bag down gently. “You did good documentation,” he said. “But this is beyond solo evidence collecting.”

Lumi wiped her eyes and looked at him warily. “Who are you?”

“The man who was trying to fix your hinge and accidentally found your private detective phase.”

That got the smallest crack of a smile out of her.

Then her expression collapsed again. “I didn’t know what to do,” she said to me. “The first time I reported him, they said if he hadn’t threatened me directly, there wasn’t much they could act on. So I started gathering everything. Dates. places. plates. patterns. I thought if I had enough, they’d have to listen.”

I wanted to be angry. I was angry. But under it was something heavier—guilt.

Because there had been signs. The extra locks she installed last month. The sudden habit of sharing her location “just in case.” The way she stopped jogging after sunset. The baseball bat I’d noticed behind her front door and joked about.

I hadn’t seen what was right in front of me because the version of Lumi in my head was still the little sister who needed rescuing from spilled paint and overdue rent, not the grown woman quietly trying to survive fear.

“We’re going to the police,” I said.

She looked down. “There’s more.”

Every muscle in my body tightened. “What more?”

Her voice dropped to almost nothing.

“I think I know who he is.”
