(From the publisher):
That there was ever a planet called Earth only Earl Dumarest believed. He had been seeking it a long time, though nobody else at the crowded galactic center believed in it.
He had acquired some bits of information during his search outwards: a Terrestrial zodiac, an authentic painting of Luna, a general series of hints that he was getting closer. Then he learned of a man who knew where Earth was, who had the special coordinates that would take a starship directly to it!
The man had lived on Elysius, and his widow knew where his data were. She demanded a price from Dumarest - a chore that involved a mining expedition which would bring her back a fortune and him the information.
But Elysius was not the Elysium its name projected - and The Terra Data not so rapidly come by!
