"Neither can I, and they probably won't either," Keating told her. "But they'll go ahead and do it. Why, Scott, they're pulling the Number One Doernberg-Giardano, tonight. By oh-eight-hundred, it ought to be cool enough to work on. Where will we hold the tests? Here?"

"We'll have to, unless we can get Dr. Rives security-cleared." Melroy turned to her. "Were you ever security-cleared by any Government agency?"

"Oh, yes. I was with Armed Forces Medical, Psychiatric Division, in Indonesia in '62 and '63, and I did some work with mental fatigue cases at Tonto Basin Research Establishment in '64."

Melroy looked at her sharply. Keating whistled.

"If she could get into Tonto Basin, she can get in here," he declared.

"I should think so. I'll call Colonel Bradshaw, the security officer."

"That way, we can test them right on the job," Keating was saying. "Take them in relays. I'll talk to Ben about it, and we'll work up some kind of a schedule." He turned to Doris Rives. "You'll need a wrist-Geiger, and a dosimeter. We'll furnish them," he told her. "I hope they don't try to make you carry a pistol, too."

"A pistol?" For a moment, she must have thought he was using some technical-jargon term, and then it dawned on her that he wasn't. "You mean—?" She cocked her thumb and crooked her index finger.

"Yeah. A rod. Roscoe. The Equalizer. We all have to." He half-lifted one out of his side pocket. "We're all United States deputy marshals. They don't bother much with counterespionage, here, but they don't fool when it comes to countersabotage. Well, I'll get an order cut and posted. Be seeing you, doctor."
