Before there could be any answer, Arthur Gerrol leaned forward earnestly and said, "Mr. Martin, we don't just represent businessmen who have been robbed. We also represent hundreds and hundreds of people who have had friends and relatives murdered by that horror. Little people, Mr. Martin. Ordinary people who are helpless against the terror of a superhuman evil. This isn't just a matter of money and goods lost—it's a matter of lives lost. Human lives, Mr. Martin."

"They're not the only ones who are concerned, either," Vandenbosch broke in. "If that hellish thing isn't destroyed, more will die. Who knows how long a beast like that may live? What is its life-span? Nobody knows!" He waved a hand in the air. "For all we know, it could go on for another century—maybe more—killing, killing, killing."

The detective looked at them for a moment in silence. These three men represented more than just a group of businessmen who had grown uneasy about the Government's ability to catch the Nipe; they represented more than a few hundred or even a few thousand people who had been directly affected by the monster's depredations. They represented the growing feeling of unrest that was making itself known all over Earth. It was even making itself felt out here in the Belt, although the Nipe had not, in the past decade, shown any desire to leave Earth. Why hadn't the beast been found? Why couldn't it be killed? Why were its raids always so fantastically successful?

For every toothmark that inhuman thing had left on a human bone, it had left a thousand on human minds—marks of a fear that was more than a fear. It was a deep-seated terror of the unknown.

The number of people killed in ordinary accidents in a single week was greater than the total number killed by the Nipe in the last decade, but nowhere were men banding together to put a stop to that sort of death. Accidental death was a known factor, almost a friend; the Nipe was stark horror.

The detective said: "Gentlemen, I'm sorry, but what I said in my last letter still goes. I can't take the job. I will not go to Earth."

Every one of the three men could sense the determination in his voice, the utter finality of his words. There was no mistaking the iron-hard will of the man. They knew that nothing could shake him—nothing, at least, that they could do.

But they couldn't admit defeat. No matter how futile they knew it to be, they still had to try.

Nguma took a billfold from his jacket pocket, opened it, and took out an engraved sheet of paper with an embossed seal in one corner. He put it on the desk in front of the detective.

"Would you look at that, Mr. Martin?" he asked.
