It was after 2 a.m. when Professor Maddox awoke with the sensation that something was vaguely wrong. He sat up in bed and looked out the window at the starlit sky. He remembered he had left Ken at the university and had not yet heard him come in.
Quietly he arose from the bed and tiptoed along the hallway to Ken's room. He used the beam of a precious flashlight for a moment to scan the undisturbed bed. Panic started inside him and was fought down.
Probably Ken had found something interesting to keep him from noticing the alarm clock on a shelf in the laboratory. Perhaps someone had even forgotten to wind the clock and it had run down.
Perhaps, even, the bearings of its balance wheel had finally become frozen and had brought it to a stop!
Mrs. Maddox was behind him as he turned from the door. "What's wrong?" she asked.
He flashed the light on the bed again. "I'd better go up to the laboratory and have a look," he said.
Ken's mother nodded. She sensed her husband's worry, and wanted not to add to it. "Take Ken's bicycle," she said. "It will be quicker, even if you have to walk it uphill. I'll have some hot chocolate for you when you come back."
Professor Maddox dressed hurriedly and took the bicycle from the garage. He did have to wheel it most of the way up the hill, but it would be easier coming down anyway, he thought. He wondered how much longer the bearings in it would hold up without freezing.
As he came within view of the laboratory building he saw that the windows were utterly dark. He knew that even with the shades down he would have been able to see some glow of the oil lamps which they used, provided Ken were still there.
He waited a full 10 minutes against the chance that Ken had put out the lamps and was on his way out. Then he knew Ken had gone long ago. He ought to call the Sheriff and have the police cars search for him, but there were no phones and no cars.
