But the Satorians weren't fools; they didn't expect Nansal to swallow the same bait a second time. Sator had another ace up her sleeve.
Ten days after they arrived, every diplomat and courier of the Satorian delegation committed suicide!
Puzzled, the government of Nansal reported the deaths to Sator at once, expecting an immediate renewal of hostilities; they were quite sure that Sator assumed they had been murdered. Nansal was totally unprepared for what happened; Sator acknowledged the message with respects and said they would send a new commission.
Two days later, Nansal realized it had been tricked again. A horrible disease broke out and spread like wildfire. The incubation period was twelve days; during that time it gave no sign. Then the flesh began to rot away, and the victim died within hours. No wonder the ambassadors had committed suicide!
Millions died, including Torlos' own father, during the raging epidemic that followed. But, purely by lucky accident, the Nansalian medical research teams came up with a cure and a preventive inoculation before the disease had spread over the whole planet.
Sator's delegation had inoculated themselves with the disease and, at the sacrifice of their own lives, had spread it on Nansal. Although the Satorians had developed the horribly virulent strain of virus, they had not found a cure; the diplomats knew they were going to die.
Having managed to stop the disease before it swept the planet, the Nansalians decided to pull a trick of their own. Radio communication with Sator was cut off in such a way as to lead the Satorian government to believe that Nansal was dying of the disease.
The scientists of Sator knew that the virus was virulent; in fact, too virulent for its own good. It killed the host every time, and the virus could not live outside a living cell. They knew that shortly after every Nansalian died, the virus, too, would be dead.
Their fleet started for Nansal six months after radio contact had broken off. Expecting to find Nansal a dead planet, they were totally unprepared to find them alive and ready for the attack. The Satorian fleet, vastly surprised to find a living, vigorous enemy, was totally wiped out.
Since that time, both planets had remained in a state of armed truce. Neither had developed any weapon which would enable them to gain an advantage over their enemy. Each was so spy-infested that no move could pass undiscovered.
