After BenChaim had gone, the detective sat thinking, toying with a pencil on his desk. Moishe BenChaim, like so many others in the Belt, had come out with nothing but his brain and his two hands and the equipment necessary to keep him alive. In thirty years, he had parlayed that into one of the biggest fortunes in the Solar System. It was men like that whose respect he valued, and, on the surface, he apparently had that respect. But refusing the Nipe job would dull the bright sheen of that respect, and he knew it. BenChaim had talked about how foolish it would be to try to beat the Nipe in a face-to-face encounter, but he hadn't meant it. He knew perfectly well that all Stanley Martin would be expected to do would be to find out where the Nipe's hideout was. Once that had been accomplished, men and machines—most especially machines—could wipe the monster from the face of the Earth. One well-placed bomb would do it, if the authorities only knew where to place that bomb. If only—

Again his mind veered away, refusing to consider the Nipe too carefully or too closely.

The intercom on his desk hummed, and he pressed the switch.

"Yes, Helen?"

"That Mr. Nguma was here while Mr. BenChaim was with you, Mr. Martin. I followed your instructions and told him that you would not see him."

"Fine. Thanks, Helen."

"Also, there's a radiogram for you from Earth."

"If it's from one of Nguma's colleagues," the detective said, "I don't want to see it. File it in the cylindrical file—under W."

"I don't think it is," the secretary said doubtfully. "I can't make any sense out of it. I'd better bring it in."

"Okay. And then put that call through to Pelham. I want to get going on that Morton spaceship wrecking. I'm getting itchy for action."
