Synopsis: A spy, an archaeologist, and a lady try to find some super-race's hidden weapons cache! From the back cover of the Ace first edition: "Back before mankind entered the realm of infinite space, back before the Earth itself was anything but a primeval jungle, there were still stars that had inhabited planets and an extra-galactic empire. And when millions of years later men ventured among the stars they found only the faintest traces of this primal civilization - until the moment when a space map was found giving the coordinates of an unknown world that had been the arsenal of the unimaginably mighty weapons of the First Empire. The the quest was on - for whoever located that treasure trove first could dictate his own terms to a thousand proud planets."
