I walked down the narrow concrete corridor until I reached the heavy steel vault door.

I swiped Elias’s silver card against the electronic scanner.

The light turned from red to green with a soft, hydraulic hiss.

I pushed the door open.

Inside, the physical archives of the company were stored in floor-to-ceiling metal cabinets.

I found the cabinet labeled with the patent filings from five years ago.

This was where Elias kept the physical records of the early encryption codes Daniel had helped him steal from my father.

I opened the drawer and pulled out the logbook for the server room access.

Daniel’s signature was there, dated the exact night my father’s servers had been wiped.

Beneath his signature was a series of deleted digital timestamps that had never been erased from the physical backup.

I took out my phone and took high-resolution photos of every page, my hands steady despite the chill in the room.

Now, I had everything.

I had the proof of Daniel’s betrayal, and I had the proof of Elias’s theft.

I drove to the Fifth Avenue penthouse.
