The nurse was irresolute. "But that man needs help," she pointed out.

"Certainly he needs help," Zen agreed.

"Well—"

Zen watched her carefully. She seemed to understand his words but something else pulled at her far more strongly: the screaming of the injured man. Each time the soldier cried out, she started in his direction.

"Well, well, thank you, colonel." Turning, she moved with a sure stride up the slope.

Zen swore under his breath and started after her, then caught the motion as the question rose in him as to why she should throw her life away. She knew the meaning of radiation in lethal quantities. Unquestionably, she also knew what would happen to any normal human who ventured into a hot zone.

Was she, then, a normal human being? Was he actually witnessing one of the miracles performed by the new people? If she came off the mountain slope alive, it would certainly prove something. Zen cursed again. She was going where he could not safely follow. If she returned unharmed, he had enough proof to warrant following her to the ends of the earth, if need be.
