"Yes, yes," Bud murmured.

"Frank, you apologize! You hear me! Apologize!"

Frank and Bud found their eyes locked in a moment of silent communication, and seeing victory in the dull defeat inside of Bud, Frank said hoarsely, "I apologize, Bud. I'm sorry. I shouldn't have said those things. I lost my head. I'm sorry."

They both knew it was no apology. The threat was still very much there.


CHAPTER V

The spider ships towered above the surrounding aircraft. Their construction was utilitarian; their living quarters were cramped; entrance was achieved from the ground by means of a retractable ladder from the base platform.

The underbelly dome contained the cutting ray. It could strike deep into the Earth, burning through shale and granite with equal efficiency. The portable casing could be sunk almost simultaneously; it would seem to contain the ray as a hose contains water. While like a giant rig, the ship would poise on its triple legs above the operation. As rapidly as the crew could section the casing, the drilling would proceed.

The three ships would form a triangle. Like insects sending down stingers they would, when the time came, lance three deep shafts into the Earth. Then down the casings would plunge the identical charges. Technicians could compute the point where the three shock waves would meet. A fourth ray would enter the Earth to the proper depth; and at that point would be buried the deadly atomic seed. At the proper time, the charges would be detonated. And where their waves met, under incredible heat and pressure, there the chain reaction would begin, to explode, in an instant, the whole of the Earth.

The Oligarch summoned Herb. "You may sit at my table," he said.
