lse? You should learn to relax. It can be fun."

She started to prove it to him, and Jerry responded the way a normal,
healthy male usually does. But in the middle of an embrace, he cried
out:

"Wait a minute!"

"What's the matter?"

"I just thought of something! Now where the hell did I put my old
notebooks?"

He got up from the sofa and went scurrying to a closet. From a debris of
cardboard boxes, he found a worn old leather brief case, and cackled
with delight when he found the yellowed notebooks inside.

"What _are_ they?" Greta said.

"My old school notebooks. Greta, you'll have to excuse me. But there's
something I've got to do, right away!"

"That's all right with me," Greta said haughtily. "I know when I'm not
wanted."

She took her hat and coat from the hall closet, gave him one last chance
to change his mind, and then left.

Five minutes later, Jerry Bridges was calling the airlines.

It had been eleven years since Jerry had walked across the campus of
Clifton University, heading for the ivy-choked main building. It was
remarkable how little had changed, but the students seemed incredibly

"Professor Coltz?" She stuck a pencil to her mouth. "Well, I guess he'd

I was here. Where is this place?"

He followed her directions, and located a fresh-painted building three
hundred yards from the men's dorm. He met a student at the door, who
told him that Professor Coltz would be found in the physics department.

The room was empty when Jerry entered, except for the single stooped
figure vigorously erasing a blackboard. He turned when the door opened.
If the students looked younger, Professor Coltz was far older than Jerry
remembered. He was a tall man, with an unruly confusion of straight gray
hair. He blinked when Jerry said:

"Hello, Professor. Do you remember me? Jerry Bridges?"

"Of course! I thought of you only yesterday, when I saw your name in the
papers--"

They sat at facing student desks, and chatted about old times. But Jerry
was impatient to get to the point of his visit, and he blurted out:

"Professor Coltz, something's b
