response to a widespread demand from our readers we asked Don Wilcox to bring backthose two sterling characters of his Lester Allison and June O’Neill who first appeared inAMAZING STORIES in the June 1940 issue . Pleased with the success of his “Slave Raiders from Mercury” Author Wilcox has writtenthis entertaining sequel. The plot is entirely original but the two principal charactersface peril and heroic sacrifice with the same courage that evoked such an enthusiasticresponse from AMAZING STORIES fans . In “ Slave Raiders from Mercury” Lester Allison taking a day off at the circus foundhimself in a sideshow exhibit — a rocket ship which had somehow come down to Earth. Alsoin the ship whither she had fled to escape the unwelcome attentions of an over-zealoussuitor was June O’Neill . WHAM — the rocket ship suddenly took off into the void and our two young people presently found themselves exiled on Mercury. There they became enmeshed in the cunning clutches of Jason Kilhide a confidence man from Earth who had turned all of Mercury into a profitable racket of which he was the guiding genius. Kilhide’s self-returning space ships were used to kidnap young people from Earth to become slaves of the Dazzalox the ruling class of Mercury. Lester Allison nearly gave up his life in combatting this evil system but finally succeededin destroying the last vestiges of this corrupt regime Kilhide included. Thereupon he andJune O’Neill and four other young Earth couples — the rest had been sent back home — decided to spend their lives on Mercury a haven now where they would never be molested andin addition would be able to make use of the marvelous scientific achievements which Kilhidehad unwillingly left behind. Now in this sequel we have Lester Allison and June O’Neill confronted with another greatcrisis on which solution depends their very lives. — Ed. An ANN/A Preservation Edition.
