Harry Zeckler is a smooth-talking Terran con man who thinks he can swindle his way through any deal—until he tries it on Altair, where land means survival and deception can be fatal. Dragged before a hostile alien court, he faces charges ranging from murder and conspiracy to sacrilege and espionage, while his weary lawyer Paul Meyerhoff watches a trial built on prejudice, performance, and alien logic rather than justice. Zeckler's defense becomes a desperate gamble when he discovers the Altairians are perfectly logical, yet governed by values utterly unlike Earth's. He hurls out a paradoxical claim—that all Earthmen are incapable of telling the truth—and briefly turns the courtroom into chaos. But victory is only an illusion. Zeckler's stunt may save his life, yet it destroys hopes for peaceful contact between Earth and Altair and leaves Meyerhoff furious at the fallout. As missing bank papers and a fresh arrest close in, the con man's latest scheme becomes a satirical warning about greed, cultural blindness, and the dangerous cost of assuming alien worlds play by human rules.
