Night Train to Rigel

More than two hundred years from now, the Quadrail transportation system run by the enigmatic Spiders connects civilizations throughout the galaxy. But someone is threatening the entire system and the worlds it serves with a military force that could wreak interstellar havoc. Frank Compton, a sharp investigator, lost his job with Earth's security forces when he exposed a corrupt scheme that had roots in high places. Enlisted by the Spiders to find out who's trying to take over the Quadrail, he's got his hands full. Beings of many races are gunning for him, trying to keep him from discovering a far- flung conspiracy that could destroy every civilization in the galaxy.
