From the very moment he had heard that "Stanley Martin" had arrived to take charge of the project, Bart Stanton pushed all thoughts of his brother out of his mind. He had fouled up once by thinking of himself rather than thinking of what had to be done; he would not make that mistake again.

Nor, apparently, did Martin have any desire to meet Bart Stanton. He took control of the project smoothly. Apparently Mannheim had taken into account the possibility of his own death and had arranged things accordingly. Although Martin was not a member of the World Police, his own record showed that he had the ability to handle the job, and an Executive Session had unanimously accepted Colonel Mannheim's wishes in the matter. There was little else they could do; the very fact that Mannheim had died in the way he had, ordering the guard to hold his fire, had stilled those voices on the Executive Council who had been wavering before.

Martin had come in to Earth almost secretly, without fanfare, and the general public was totally unaware that anything at all had happened.

Special messages, going through the channels known to be tapped by the Nipe, said that it would not be in the public interest to admit that the Nipe could actually penetrate the defenses of World Police Headquarters, so the Nipe was not surprised when the public news channels announced quietly that Colonel Walther Mannheim, the man who had been decorated twelve years before for the quelling of the Central Brazilian Insurrection, had died peacefully in his sleep. The funeral was quiet, but with full honors.

Stanton stopped worrying about such things. Until he had done the job that he had been rebuilt for, he was determined to make that goal his sole purpose. As the weeks sped by, he kept determinedly to his regime, exercising regularly to keep himself in top physical condition, and studying the three-dimensional motion studies of the Nipe in action.

Only one of these made him ill the first time he watched it, but it was the only recording of the Nipe actually in the process of killing a man, so he watched, over and over again, the shots taken from the gun tower when the Nipe attacked Colonel Mannheim.

A full-sized mockup of the Nipe's body had been built, with the best approximation possible of the Nipe's bone structure and musculature, and Stanton worked with it to determine what, if any, were the Nipe's physical limitations.

His only periods of relative relaxation occurred when he discussed the psychological peculiarities of the Nipe mind with George Yoritomo.

One afternoon, after a particularly strenuous boxing session, he walked into Yoritomo's office with a grin on his face. "I've been considering the problem of the apparent paradox of a high technology in a ritual-taboo system."

Yoritomo grinned back delightedly and waved Stanton to a chair. "Excellent! It is always much better if the student thinks these things out for himself. Now, while I fill this hand-furnace with tobacco and fire up, you will please explain to me all about it."
