Chapter 2: The Logic of the Blueprint

Julian let out a sharp, dismissive chuckle, turning his back on the vault door. "Keep your dignity if it makes you feel better, my dear. But the insulation is soundproof, the cellular signals are jammed, and the digital locks are hardwired to my personal mainframes. You have exactly twenty minutes before hypothermia sets in."

Behind the frosted glass, Evelyn didn't waste a breath. She knew every single circuit, every pneumatic line, and every line of code that governed the Vance estate.
