Doctor Kinney is the leader of group of space explorers from Earth, Kinney and three others, who travel to explore the planets. To accomplish this, they utilize a system of magnetic travel designed by Dr. Kinney. They use Kinney's invention to travel in a cube-shaped vehicle called a Sky Cube, a sky-car, or simply a car. Doctor Kinney is married, although Mrs. Kinney doesn't travel with the explorers. The second mission takes them to Venus, where they encounter an androgynous, pyschic race of people under a glass dome covering an enclosed atmosphere of Venus. This story is The Queen of Life.
