Part 1
Part 2
Deep beneath Mercury’s blistering surface, a team of Earth‑based operators pilots massive, heat‑proof mining machines called Proxies, sending them into the planet’s scorching fissures to extract the precious uranium that powers the world. When a routine dive goes dark, the seasoned operator Doug Norris feels a familiar, unsettling sensation—another unexplained failure that has already claimed several of his colleagues’ machines. As he watches the glowing gas clouds and the silent blackouts, he begins to suspect that something more deliberate than chance is at work.
Back at the control station in New York, Norris confronts project leader Martin Kincaid with a daring theory: the string of recent catastrophes may be sabotage, not accident. The tension rises as they weigh the stakes of a dwindling uranium supply against the hidden dangers lurking in Mercury’s hostile depths. Listeners are drawn into a tense, high‑tech mystery where every decision could mean the difference between a breakthrough and a disaster.
