Waldour nodded.

For the first time since he had known and worked with Kelgarries Ashe saw him display open astonishment.

"Camdon? But he was sent us by...." The colonel's eyes narrowed. "He must have been sent.... There were too many cross checks to fake that!"

"Oh, he was sent, all right." For the first time there was a note of emotion in Waldour's voice. "He was a sleeper, a very deep sleeper. They must have planted him a full twenty-five or thirty years ago. He's been just what he claimed to be as long as that."

"Well, he certainly was worth their time and trouble, wasn't he?" James Ruthven's voice was a growling rumble. He sucked in thick lips, continuing to stare at the disks. "How long ago were these snooped?"

Ashe's thoughts turned swiftly from the enormity of the betrayal to that important point. The time element....that was the primary concern now that the damage was done, and they knew it.

"That's one thing we don't know." Waldour's reply came slowly as if he hated the admission.

"We'll be safer, then, if we presume the very earliest period." Ruthven's statement was as ruthless in its implications as the shock they had had when Waldour announced the disaster.

"Eighteen months ago?" Ashe protested.

But Ruthven was nodding. "Camdon was in on this from the very first. We've had the tapes in and out for study all that time, and the new detector against snooping was not put in service until two weeks ago. This case came up on the first checking round, didn't it?" he asked Waldour.

"First check," the security man agreed. "Camdon left the base six days ago. But he has been in and out on his liaison duties from the first."

"He had to go through those search points every time,"

Kelgarries protested. "Thought nothing could get through those." The colonel brightened. "Maybe he got his snooper films and then couldn't take them off base. Have his quarters been turned out?"

Waldour's lips lifted in a grimace of exasperation.

"Please, Colonel," he said wearily, "this is not a kindergarten exercise. In confirmation of his success, listen...." He touched a button on his desk and out of the air came the emotionless chant of a newscaster.

"Fears for the safety of Lassiter Camdon, space expediter for the Western Conference Space Council, have been confirmed by the discovery of burned wreckage in the mountains. Mr. Camdon was returning from a mission to the Star Laboratory when his plane lost contact with Ragnor Field. Reports of a storm in that vicinity immediately raised concern...." Waldour snapped off the voice.

"True....or a cover for his escape?" Kelgarries wondered aloud.

"Could be either. They may have deliberately written him off when they had all they wanted," Waldour acknowledged. "But to get back to our troubles....Dr.

Ruthven is right to assume the worst. I believe we can only insure the recovery of our project by thinking that these tapes were snooped anywhere from eighteen months ago to last week. And we must work accordingly!"
