A daring Earth expedition finally reaches the red deserts of Mars, only to find a small, tall‑bodied species waiting in the shadows. The crew—engineer Von Frisch, Captain Powers, and a handful of specialists—must decide quickly whether to greet or flee, aware that a misstep could spark an interplanetary tragedy. Their first impressions are strange: the Martians’ elongated limbs and oversized heads suggest a form of intelligence unlike any on Earth, but their motives remain a mystery.
With no universal language to rely on, the team resorts to the oldest tool of dialogue: mathematics. Von Frisch sketches a right‑angled triangle in the sand, marks the sides, and watches as a Martian adds a line that proves they grasp the Pythagorean theorem. Encouraged, he draws a sun, surrounding orbits, and points to Earth and Mars, hoping the shared symbols will bridge the gap between worlds. As tension builds, listeners are drawn into the fragile moment where curiosity battles caution, and the very act of communication could shape the future of both species.

A veteran newspaperman who also became a prolific science fiction writer, he brought a reporter’s eye for detail to stories about alien worlds, future societies, and human nature. His work ranges from brisk adventure to thoughtful speculation, with a long career that stretched well beyond the magazine era of 1950s SF.
