Then, the battle over, he stood there, swaying. Eyes glazing, he dropped to his knees and sagged over the body of Marima Saan....

Mary Mason opened her eyes in bewilderment and looked up at Don Jensen bending over her. On his forehead the silver electrode was still strapped, but broken wires dangled from it, over one ear.

"What happened?" she asked.

"I don't exactly know," he said. "But I do know you suddenly dashed over and clouted me in the face. Then everything went black for what I judge was quite a period of time. I must have fallen off the couch, finally, and broken the wires, which stopped the machine. Anyway, I came to to find you lying beside me on the floor. Whatever was the idea of bashing me?"

A flood of red suddenly rose to her cheeks. "Now I remember," she said. "It was what you were thinking! It was on the screen!"

It was his turn to redden. "What was on the screen?"

"You know very well." She got to her feet, went over to the television screen and looked into it. It was blank.

He followed her over, removing the electrode from his forehead. He tossed it on the bench and looked at the clock. "Twenty minutes," he said.

"Twenty minutes what?" she asked.

"We were both out twenty minutes, and all the time the machine was running. So, whatever was recorded, the only evidence we'll have is the camera. Might as well run it back and see what you missed."

She stiffened. "Lord knows what's on it. If what you started out with is any criterion."

He grinned at her. "It's my thoughts, not yours, which are going to be exposed to the public, in this case you," he said. "And while I develop the film, I suggest you powder up a bit. You look a bit wan and tired...."

"Before I do," she said, "I want to warn you."

"About what?"

"It wasn't just lines and patterns and lights on the screen. It was actual pictures."

He gaped at her. "Pictures!"

"Yes. And it means at least one of the results of our experiments are going to be sensational. The pineal gland may be the answer to perfect psychiatric diagnosis, because it seems that it translates the brain waves into actual pictures."

"The pineal gland—an eye in reverse!" he gasped.

"Exactly. And now, I'll leave you. And if you don't care to show me these particular pictures, I'll...."

"Judging from what I was thinking initially, it's going to be a pleasure!" he said.

She swept furiously from the room.

Two hours later he seated her before the projection screen and went back to the projector.

"If you're sure this isn't going to embarrass you...." she began.

"It won't," he assured her. "I haven't seen any of it yet, except a few interesting glimpses I caught in the darkroom. But if you look like some of the things I saw...."

"Just what do you mean?"

"Wait and see." He switched on the projector and came back to sit down beside her.

As the first picture appeared on the screen, only an indistinct white pillar was visible. It swirled, thickened, grew more distinct. A face appeared. "It's you," he said.

"Yes," she said. "And then I turned up the power to bring the image up stronger."

The image on the screen clarified. He drew a long breath. "Nice!" he breathed. "And I gather that's where you socked me?"

"Don't you think I should have? Is that all you've ever got in your head...."

"Wait a minute," he said in a strained voice. "There's more of what's in my head, apparently. But I swear I never saw any of that before!"

The two watched in amazement as the dim confines of the weird valley flashed on the screen. They saw the shadowy bulk of the monster moving about. Then abruptly the scene changed, and Mary gasped.

"Brannan!" she choked. "But how evil he looks!"

"Oh, I don't know.... That's the way I picture him...."

"In a long cloak?" she asked.

"And with a dagger," he agreed.

Now Mary gasped
