first few minutes must have had compressed in them the agonies of a lifetime!

Matson grinned coldly. The aliens were not invulnerable. If Mankind could be taught to fear and hate them, and if that emotion could be focussed, they never again would try to take this world. It would be sheer suicide. As long as Mankind kept its emotions it would be safe from this sort of invasion. But the problem was to teach Mankind to fear and hate. Shock would do it, but how could that shock be applied?

The thought led inevitably to the only possible conclusion. The aliens would have to be killed, and in such a manner as to make humanity fear retaliation from the stars. Fear would unite men against a possible invasion, and fear would force men to reach for the stars to forestall retribution.

Matson grinned thinly. Human nature couldn't have changed much these past years. Even with master psychologists like the Aztlans operating upon it, changes in emotional pattern would require generations. He sighed, looked into the anxious face of Seth Winters, and returned to the reality of the desert night. His course was set. He knew what he had to do.
