Something took him to it. He put his finger on a spot north and east of the Hawaiian Islands. And even then he couldn't have said why he asked his question.
"Your volcanic formation was about here, wasn't it, Bjarnsson?"
The tall Norseman stared at him with cold shrewd eyes. "Yes. Why?"
"Look here." Fallon drew a rough circle with his fingertip, touching the Pacific Coast, swinging across the ocean through the Gilberts and the Marshalls, touching Wake, and curving up again to Vancouver.
"The volcanic formation is the center of that circle," Fallon said. "It was also the epicenter of the recent quake, according to Cal-Tech seismologists. That's what gave me the hunch. The monsters seem to be fanning out in a circle from some central point located about there."
"That is already explained," said Bjarnsson. "The Japanese may have their projector located there. And why not?"
"No reason at all," Fallon admitted. "You mentioned, in your interview, something about a Japanese ocean survey ship coming up just as you left. That ship might still have been near there at the time of the quake, mightn't it?"
"It is possible. Go on." There was a little sharp flame flickering in Bjarnsson's eyes.
Fallon said, "Could these super-evolutionary rays be caused by volcanic action?"
Bjarnsson's grey-blond shaggy brows met, and the flame was sharper in his eyes. "Fantastic. But so is this whole affair.... Yes! If an area of intense radioactivity were uncovered by an earth-shift, the sea and all that swims in it might be affected."
