The Night I Found My Husband's Secret GPS Tracker on My Sister's Car — Part 2 of 3

The Tracker Under the Seat Was Small, Metal, and Humming With Secrets

When Marcus didn't come back, I didn't wait. I pulled myself off the couch, my legs shaky but steady enough to carry me to the garage. I had to see for myself.

I found the tracker on my third sweep of the car—a small black disc tucked under the driver's seat, held in place by a strip of industrial tape. It was still warm, as if it had been placed there recently.

My hands trembled as I pulled it free. I turned it over, and there, on the back, was a tiny serial number. I recognized it immediately. It was the same kind of device Marcus used for work—he was a security consultant, he'd explained once. He installed them in client homes to monitor for intruders.

But this wasn't a client's home. This was my car.

The front door clicked open, and I spun around. Marcus stood in the doorway, his jacket wet from the rain that had started to fall. His eyes landed on the tracker in my hand, and I saw the exact moment his composure cracked.

"Lena," he said, taking a step toward me. "I can explain."

"Don't," I said, holding up my hand. "Don't you dare come near me."

"You have to understand," he said, his voice breaking. "I was trying to protect you. After what happened to your sister, I couldn't—"

"My sister?" I cut him off, my voice rising. "You mean the sister you've been lying to me about? The sister who texted you tonight, even though she's supposed to be missing?"

His face went pale. "How do you know about that?"

"Because I'm not stupid," I said, stepping closer. "I saw her name on your phone. And now I'm wondering—how long has this been going on? How long have you been tracking me?"

He opened his mouth to answer, but I didn't give him the chance. I grabbed my phone and pulled up the app he had installed on my device last month, the one he said was for "home security." I clicked on the tracking icon, and there it was—my car, blinking blue. And next to it, a second dot, blinking red.

"That's her, isn't it?" I whispered. "That's my sister's car."

Marcus's face twisted with something I couldn't read. "She's in trouble, Lena. Real trouble. I've been trying to find her before it's too late."

"Then why didn't you tell me?" I demanded. "Why not just ask for help?"

"Because you wouldn't have believed me," he said, his voice dropping low. "You would have thought I was the one who did this to her."

The words hung between us, heavy and sharp. I stared at him, and I realized—I didn't know what to believe anymore.

"Take me to her," I said. "Now."

He hesitated, and for a moment, I thought he would refuse. But then he nodded, his shoulders slumping in defeat. "Fine. But we have to go now, before—"

"Before what?" I asked.

He didn't answer. He just turned and walked toward the door, and I followed, my heart pounding in my chest.

The drive was silent, the streets dark and empty. Marcus kept his eyes on the road, his knuckles white on the steering wheel. I watched the GPS on his phone, the red dot pulsing closer and closer.

"She's in the old warehouse district," he said, turning down a gravel road. "I don't know who took her, but they've been holding her there for days."

"How do you know this?" I asked, my voice barely audible.

"Because I put the tracker on her car too," he said, not looking at me. "Right before she disappeared. I knew she was in danger, but I didn't know who from. I thought if I could find her in time—"

"Why would she be in danger?" I pressed. "What did she know?"

Marcus's jaw tightened. "She knew about the money," he said. "The money that went missing from my company last month. She found out who took it, and she was going to tell you."

I stared at him. "You think someone took her because of that?"

"I don't think," he said, pulling the car to a stop in front of a rusted metal building. "I know."

He got out, and I followed, my legs trembling. The building loomed before us, dark and silent. No lights. No sound.

"Stay behind me," Marcus said, pulling a flashlight from his pocket.

We crept through the open door, the beam cutting through the darkness. The air smelled of dust and rust, and my heart was pounding so loud I was sure he could hear it.

And then I saw her.

My sister, tied to a chair in the corner, her face bruised and swollen. Her eyes widened when she saw me, and she shook her head frantically, her mouth gagged with duct tape.

"Lena, no—" Marcus started, but it was too late.

She was already screaming through the tape, her voice muffled but clear enough: "He's the one! He's the one who did this!"

I turned to Marcus, and in the dim light, I saw the truth written on his face. He wasn't here to save her.

He was here to finish the job.
