Nomad

The narrative follows Guy Maynard, an aide to a Terran Space Marshal, who is abducted by Martians demanding the secret location and orders of the starship Orionad. Strapped aboard an almost invisible vessel and threatened with chemical and surgical coercion, he endures interrogation that plays on technological weaknesses and personal stakes. The action broadens into interplanetary maneuvering as espionage, diplomatic tension, and strategic debates over exploration missions heighten conflict between Terra and Mars. Technological ingenuity, loyalty, and ethical choices drive responses to captures and countermeasures, leading to revelations about the political and scientific consequences of the missing ship.
