"So what?" Loring said laconically. If the chief was not worried about these things, the henchman would not be worried, either.

"So I rigged up a detector that is both automatic and instantaneous. At the first touch of any unusual vibration it will throw in the full space drive and will shoot us directly away from the point of the disturbance. Now we shall be absolutely safe, no matter what happens.

"We are safe from any possible attack; neither the Fenachrone nor our common enemy, whoever they are, can harm us. We are safe even from the atomic explosion of the entire planet. We shall stay here until we get everything that we want. Then we shall go back to the Green System. We shall find Seaton."

"Sour? Along what line?"
