This was no longer a story told by one man; it had become a problem, a situation to be evaluated objectively.

"Well, sir ... the only part of the thing I can comment on at this point is the stuff about O'Connor and Walters. That checks. They both disappeared without a trace. It was treated as a maximum security situation, and we did give out the story they had been assigned to special duty." He glanced briefly at Forster. "Up until now, we assumed that only the directors at Aiken and Oak Ridge knew the real situation—outside of the Atomic Energy Commission and C.I.A., of course. This represents a very serious leak—or...." His voice trailed away.

"Colonel Barfield, Intelligence?"

The young colonel tried to sound flippant, unsuccessfully.

"General, acting on the assumption the story is true, it would answer about two hundred question marks in our files. Maybe more, with further study."

The C.I.A. man cleared his throat and raised a finger.

"For everybody's information," he said, "a preliminary field check shows that Dr. Preston's train was stopped for ten minutes by fog last night. The train's radar installation failed simultaneously. There wouldn't be anything odd about that except the temperature at the time was about 65 degrees, and the humidity was only 55 per cent. Consider that, gentlemen.

"Theoretically, fog can't form under such conditions. Similar local fog occurred on the occasions when O'Connor and Walters were reported missing. The Met. people couldn't explain that, either. That's all."

Morganson sat up straight, as though he had suddenly made a decision.

"I don't think there's any value in further discussion at this point. You will all have transcripts of Dr. Forster's statement within a few minutes. According to that statement, we are due to lose a number of key men in the next few hours. I'll have Code One emergency precautions instituted at all research establishments, and I think the chairman of the Joint Chiefs should hear from me right away. Colonel Barfield, I'd like you to ask Colonel Malinowski, the Russian military attaché to see me here not later than an hour from now. We'll have a full dress conference here at 8 o'clock tomorrow morning, with written evaluation reports in detail from all branches. Dr. Forster, consider yourself assigned to Pentagon duty as of now, and until further notice."
