Marcus clicked the folder, and a prompt popped up, asking for a physical authorization key.

“It’s looking for a USB security token,” Marcus said, his face falling. “Trevor must have carried it on him.”

I thought back to the night Trevor was suspended.

He had dropped his key ring on the desk, and I had put it in the safe in the back room.

“Wait,” I said, running out of the office and down the short hallway to the walk-in freezer area, where the manager’s safe was located.

My hands were shaking as I spun the dial of the wall safe, recalling the combination Trevor had made me memorize.

The heavy metal door swung open.

Inside, resting on top of a stack of cash envelopes, was a heavy brass key ring with a small, black USB drive attached to it.

I grabbed the drive and ran back to the office, my breath forming white clouds in the cold air.

“Is this it?” I asked, handing the USB drive to Marcus.

He plugged it into his laptop.

The red warning on the screen vanished, replaced by a green progress bar that began to fill.
