The Door Through Space
Author: Marion Zimmer Bradley
 
The Terran Empire maintains its sovereignty across half a galaxy - with the consent of the governed. It is a peaceful reign, maintained by agreement and not by conquest. If anarchy ever threatens, law and order in the Empire is kept by the mind-power of a handful of men.
Race Cargill is one of those men - a member of the Terran Secret Service.
Because of them there has never been open war  . . . yet.
