"When the Trelawneys' machine was examined, was the supply of YM adequately shielded?"
"Quite adequately," Camhorn said.
"But when I opened the door, the laboratory was hot. And Miguel Trelawney died of radiation burns...."
Camhorn nodded. "Those are facts that give your theory some substance, lieutenant. No question about it. And there is the additional fact that after you shut off the YM flow in the laboratory, nearly ten minutes passed before the apparent contact between two time periods was broken. Your report indicates that the phenomena you described actually became more pronounced immediately after the shutoff."
"Yes, sir."
"As if the aliens might have been making every effort to retain contact with our time?"
"Yes, sir," Dowland said. "That was my impression."
"It's quite plausible. Now, the indications are that Paul Trelawney actually spent considerable time—perhaps twelve to fourteen hours, at any rate—in that other period. He gave no hint of what he experienced during those hours?"
"No, sir, except to say that it was night when he appeared there. He may have told Miss Trelawney more."
"Apparently, he didn't," Camhorn said. "Before you and he went into the laboratory, he warned her to watch for the approach of a creature which answers the description of the gigantic things you encountered twice. But that was all. Now, here again you've given us your objective observations. What can you add to them—on a perhaps more speculative basis?"
