Deathworld centres on Jason dinAlt, a professional gambler who uses his somewhat erratic psionic abilities to tip the odds in his favour. He is challenged by a man named Kerk Pyrrus (who turns out to be the ambassador from the planet Pyrrus) to turn a large amount of money into an immense sum by gambling at a government-run casino. He succeeds and survives the planetary government's desperate efforts to steal back the money. In a fit of ennui, he decides to accompany Kerk to his home, despite being warned that it is the deadliest world ever colonized by humans...DEATHWORLD! This is one of the classics of the Golden Age of science fiction, born in the pages of Astounding Science Fiction under the editorship of John W. Campbell, Jr.
Jason dinAlt sprawled in soft luxury on the couch, a large frosty stein held limply in one hand. His other hand rested casually on a pillow. The gun behind the pillow was within easy reach of his fingers. In his line of work he never took chances. It was all highly suspicious. Jason didn't know a soul on this planet. Yet the card sent by service tube from the hotel desk had read: Kerk Pyrrus would like to see Jason dinAlt. Blunt and to the point. He signaled the desk to send the man up, then lowered his fingers a bit until they brushed the gun butt. The door slid open and his visitor stepped through. A retired wrestler. That was Jason's first thought. Kerk Pyrrus was a gray–haired rock of a man. His body seemingly chiseled out of flat slabs of muscle. Then Jason saw the gun strapped to the inside of the other man's forearm, and he let his fingers drop casually behind the pillow.
