"We have received a warning from your colleagues," Elfor said grimly. "They broadcast to us a short time ago that if harm came to you, this city and others will be destroyed before they leave the solar system. In case you knew of this and it has in any way raised your hopes, I wish to remind you that Earth's cities have been destroyed before. This threat will not affect our decision to mete strict justice to you. "You are charged with being enemies of the people of Earth, and with having landed on Earth under false colors with the intent of sabotage and espionage. Your prosecutor will be Fifth Tech Jatoo, representing the nations of Earth. You will be permitted to speak in your own defense." Jatoo was a slender, thin-faced man with the air of an experienced attorney. "The governments of Earth make these charges against the joint defendants," he began matter-of-factly: "That they are members of a rebellious and traitorous group who are allied with the Jovians and maintain an illegal, secret base on some planet or moon of the solar system; that they came here under the guise of strangers, with the specific intent of espionage and sabotage of Earth's defense against the Jovian enemy; and that they actually began such operations. "We shall present the following major evidence in support of these charges: "First, that the defendants did travel from the Numex spaceport to the military town of Pebbro in a vehicle, the motive power of which is still unknown but which obviously must utilize fuel, in violation of the conservation laws; "Second, that the defendants' colleagues did not approach the peoples of Earth in peace, but remained enfortressed in an armed space vessel; "Third, that the defendants Phil Alcorn and Fran Golden did throw the switches activating the electrical system and powered water system of the military town of Pebbro, that the above-named two defendants did utilize a military power vehicle for pleasure purposes and that all the defendants did unnecessarily destroy glass drinking vessels, all in violation of the conservation laws; "And, fourth, that the starship Discovery, listed in ancient records as having departed on a colonizing mission to the third planet of the star Deneb, was not scheduled to return to Earth for another seventy-five years and therefore could not be the ship in which the defendants arrived, as claimed." Elfor inclined his head toward the quartet from the starship, who sat behind a long table on the side of the room opposite Jatoo. "You may state what your defense will be," he said.
