In the twenty-second century, a future in which mortaline wire controls the weather on the settled planets and entire refugee camps drowse in drug-induced slumber, no one alive or dead, human or alien is quite what they seem. When terrorists manage to crash Coral, the moon, into its home planet of Ribon, forcing evacuation, it's up to Dave Crowell and Alan Brindos, contract detectives for the Network Intelligence Organization, to solve a case of interplanetary consequences. Crowell and Brindos's investigation plunges them neck-deep into a conspiracy much more dangerous than anything they could have imagined. The two detectives soon find themselves separated, chasing opposite leads: Brindos has to hunt down the massive Helkunn alien Terl Plenko, shadow leader of the terrorist Movement of Worlds. Crowell, meanwhile, runs into something far more sinister, an elaborate frame job that puts our heroes on the hook for treason. Crowell and Brindos are forced to fight through the intrigue to discover the depths of an interstellar conspiracy. And to answer the all-important question: Who, and what, is the Ultra Thin Man?
