The planet had two unique elements. One was that it produced the galaxy’s most elusive and most desirable hallucinatory drug. The other was that it was a stock brokers’ paradise. The world was split into rich men’s holdings and every day, every hour, every minute these were being traded on a continuous stock market. Up and down went values and rights as men conspired to seize other’s properties, to push prices down and cost up. Their money game controlled everything else.
Earl Dumarest went there to find his next stake. Find the drug-gem or manipulate the market - two possibilities. But behind the scenes stood the advisors of the inhuman Cyclan determined to fix the odds against Dumarest.
Edwin Charles Tubb (1919–2010) was a British writer of science fiction, fantasy and western novels. The author of over 140 novels and 230 short stories and novellas, Tubb is best known for The Dumarest Saga (US collective title: Dumarest of Terra) an epic science-fiction saga set in the far future. Michael Moorcock wrote "His reputation for fast-moving and colourful SF writing is unmatched by anyone in Britain."
Much of Tubb's work has been written under pseudonyms including Charles Grey, Carl Maddox, Alan Guthrie, Eric Storm and George Holt. He has used more than 50 pen names over five decades of writing although some of these were publishers' house names also used by other writers: Volsted Gridban (along with John Russell Fearn), Gill Hunt (with John Brunner and Dennis Hughes), King Lang (with George Hay and John W. Jennison), Roy Sheldon (with H. J. Campbell) and Brian Shaw.
