I’ll bet a Martian fire-opal against an etheradio that Margulise [sic] won’t like this.

He had been in the interior of Titan’s wild North Continent, covering the small but interesting war there for the Stellar Telenews Syndicate and the five hundred odd telenews sheets throughout the System that subscribed to the releases of that great news-gathering organization. Then Gallard’s etheradio message had ordered him to board the Saturn-to-Mars spaceliner Empress of Mars, and report at once to the Syndicate’s branch headquarters in the Martian city of Anzoc.
