Chapter 5

Arthur didn't hesitate. He unzipped the side pocket of his tool pouch and pulled out a small, worn leather roll containing a set of custom-machined hex keys he had used during his decades working on precision architectural carpentry. He flipped through the set until his thumb brushed against a rusted, non-standard triangular wrench he had salvaged years ago from an abandoned machine shop.
"Will this work?" Arthur asked, holding it up.
Vance squinted at the tiny tool, nodding slowly. "If it's a three-millimeter metric wedge, it should catch the internal threading. Try it."
Arthur knelt beside the table, positioning the heavy lockbox so the light from the grimy window hit the bottom plate. The serial number was stamped deeply into the metal: MV-704-C. Directly beneath the numbers, a microscopic seam outlined a concealed cover plate held in place by two tiny triangular screws. With steady, practiced hands, Arthur inserted the wrench. It fit with a satisfying, precise click. He turned it counterclockwise, feeling the resistance of rusted threads before the first screw backed out. The second screw followed easily.
The small metal plate dropped into his palm, revealing a tiny mechanical lever attached to a spring-loaded latch. Using the tip of his screwdriver, Arthur pushed the lever upward. With a sharp, metallic snap, the main lid of the titanium box popped open an inch, releasing a faint whiff of ozone and old paper.
Vance stepped back, crossing his arms. "Well, I’ll be damned. You had the right tool all along."
Arthur lifted the lid the rest of the way. Inside, resting on a bed of dark protective foam, was a thick leather-bound journal with Clara’s initials embossed on the cover in faded gold leaf. Beside it lay a sleek digital flash drive and a folded manila envelope labeled in her precise, neat handwriting: If found, give to Arthur Miller.
Arthur’s hands trembled slightly as he picked up the envelope. The paper was crisp, untouched by the dampness of the salvage yard. He looked up at Vance, who was watching him with a respectful distance. "Can I use your desk for a moment?"
"Take all the time you need," Vance muttered, turning back to his brass fittings to give the grieving father a semblance of privacy.

Arthur sat down in the squeaking wooden chair. He slid his finger under the flap of the envelope and pulled out a single sheet of lined paper. The date at the top was written three days before Clara’s disappearance. Her handwriting was rushed, far more frantic than her usual meticulous drafting style, yet every word was distinct and heavy with meaning.
Dad, the letter began, if you are reading this, it means I didn't make it out clean. The safety audits at Miller & Vance aren't failing by accident. Someone is falsifying stress test data on structural titanium components destined for public infrastructure projects. I tried to log the discrepancies through the proper internal channels, but my supervisor told me to bury the reports. I copied the raw telemetry data onto the enclosed drive. If anything happens to me, don't let them sweep this under the rug.
