When racial hatred turns to murderous menace . . .

First a rocket ship loses its engines on take-off and is destroyed. On board - an important extra-terrestrial visitor.

Next someone slams into the sealed vehicle used for transporting aliens around in the lethal atmosphere of Earth.

Then the vital controlled environment for the Tau Cetian delegation is sabotaged. Oxygen leaks in, and the aliens are half burnt alive.

Even if it means brutal murder, The Stars Are For Man League is determined to shatter the harmony between Earth and civilizations on other planets - and to keep mankind supreme among the alien life forms. Only one man can stop them - a man who unknowingly nurses a viper in his bosom . . .
