The second shell

A weary night‑shift reporter at the San Francisco Times is pulled from his routine by a grizzled, bronze‑skinned stranger bearing a Secret Service badge. The man, Bill Johnson, speaks of a strange case out in the Mexican desert—an old gold‑and‑thorium mine owned by Ellen Vernon, whose father, Doc Vernon, is obsessed with a dangerous new weapon. Suddenly, odd radio chirps and squeaks echo from the nearby Mocolynatal mountain, and red, stubby‑winged aircraft have been seen flying overhead, hinting at a secretive operation beyond ordinary warfare.

Drawn into the mystery, the reporter teams up with Johnson, a veteran of clandestine missions, and prepares to fly the experimental “Camel‑back” plane into the rugged terrain. Their goal is to uncover who is using the mountain as a transmitter, what the mysterious cargoes from Japanese tramp steamers conceal, and whether the feared death‑ray device truly threatens the world. The adventure promises a mix of daring aerial exploits, shadowy espionage, and speculative science that feels both vintage and oddly prescient.
