Eight Jaguar the Post-Modern Prometheus

Elvin Williams was wealthy and old. He made his fortune developing pharmaceuticals and high-tech medical equipment. Shortly after heart surgery, he launched one last big experimental breakthrough, and attempted to secure for himself an entirely new lifetime in a healthy young body. Elvin bet everything he knew on a World War II discovery that has waited until now to be revealed, a secret that will change our perception of mortality and open a new alternative for those willing to risk their sanity for a second chance at life. All one would need is some special surgery, medicine borrowed from a witch doctor and a cadaver, preferably that of a close relative.
Edited from the chief surgeon's notes, this material is all that is left of a doomed experiment. It was published to earn a living by the ruined doctor who once thought his future with Elvin was golden, but who now finds himself hunted and disgraced. He hopes that this exposition will put an end to the quest for EIGHT JAGUAR.
