Chapter 15 - The Breadcrumb Trail in the CAD

Kneeling amidst the wreckage of Tessa’s living room, I noticed a faint, blinking amber light emanating from beneath the overturned sofa cushions—a discarded flash drive that the intruders must have missed in their hurried sweep of the apartment. I scooped it up, slipped it into my inner pocket, and hurried back out to the truck before the building’s security patrol could make their hourly rounds. Once locked inside the cab with the heater running, I plugged the drive into my backup tablet. It contained only a single file: a compressed CAD assembly file named *Project_Leviathan_Rev4.dwg*. My fingers flew across the keyboard, stripping away the multi-layered encryption protocols until the architectural schematic finally rendered on the high-resolution screen in glowing green wireframe. It wasn't just a building; it was an underground hydraulic drainage system situated directly beneath the municipal harbor, designed to divert toxic industrial runoff straight into the city’s primary desalination plant—the very plant that supplied drinking water to half the state. And embedded deep within the load-bearing stress calculations was a digital watermark containing a signature I recognized instantly: the personal cryptographic stamp of Gerald Cole, the man who was supposed to be sitting in a maximum-security federal penitentiary five hundred miles away. The evidence was undeniable, but the implications were horrifying. They weren't just covering up old corporate crimes; they were actively preparing a catastrophe of apocalyptic proportions, and Tessa had stumbled onto the schematics just hours before she vanished.
