"Right," said Kingston. His hand fingered the button while his other hand turned the steering control. Maddox looked into the viewer. "Hurry!" he exploded. Kingston looked.
Ed Bronson was walking across the laboratory toward the transmission panel, saying "... and that brings one thing to mind, Ginger. If they grabbed Kingston they know where we are!"
He spun the controls quickly and pressed the button. At the same instant Kingston pressed his own button. The viewplate that showed Bronson and Virginia in Maddox's laboratory erupted in a holocaust of flame that blinded Kingston and Maddox.
"Did we?" asked Kingston, rubbing his eyes.
"We can't know," said Maddox. "But look. If we got them we can find out."
"How?"
"Collect your space-resonant elements on Earth One," said Maddox. "Then send another set across and use one of them to erupt Central City—right where Bronson's home is."
"What good will that do?" asked Kingston.
"We can watch it," explained Maddox. "And if it is returned to Earth Two, we'll know that Bronson is alive somewhere and watching."
Kingston nodded with a smile of appreciation.
