"Develop the film in those automatic cameras," Spaulding said, "and I'll show you what I'm talking about!"

As far as Colonel Spaulding was concerned, the film showed clearly what had happened. A beam of energy had leaped from the "tail" of the Q-tube, hit the ceramic tile of the wall, and burned its way through in half a second or so. The hole in the wall, surrounded by fused ceramic, was mute evidence of the occurrence of what Spaulding had seen.

But Dr. Davenport pooh-poohed the whole thing. Evidence to the contrary, he was quite certain that no such thing had happened. A piece of hot glass from a broken vacuum tube had done it, he insisted.

A piece of hot glass had burned its way through half an inch of tile? And a wall?

Davenport muttered something about the destructive effects of shaped charges. He was more willing to believe that something as wildly improbable as that had happened than admit that the device had done what Colonel Spaulding was quite certain it had done.

Within three hours, Davenport had three possible explanations of what had happened, each of which required at least four unlikely things to happen coincidentally.

Colonel Spaulding stalked back to his office in a state of angry disgust. Just because the thing was foreign to Davenport's notions, he had effectively tied his own hands—and Colonel Spaulding's, too.

"Where's Lenny Poe?" he asked the WAC sergeant. "I want to talk to him."

She shook her head. "I don't know, sir. Lieutenant Fesner called in half an hour ago. Mr. Poe has eluded them again."
