At one time Race Cargill had been the best Terran Intelligence agent on the complex and mysterious planet of Wolf. He had repeatedly imperiled his life amongst the half-human and non-human creatures of the sullen world. And he had repeatedly accomplished the fantastic missions until his name was emblazoned with glory.On Librivox: http://librivox.org/the-door-through-space-by-marion-zimmer-bradley/
But that had all seemingly ended. For six long years he’d sat behind a boring desk inside the fenced-in Terran Headquarters, cut off there ever since he and a rival had scarred and ripped each other in blood-feud.
But when THE DOOR THROUGH SPACE swung suddenly open, the feud was on again—and with it a plot designed to check and destroy the Terran Empire. (Original book blurb)
