lowly, Mersey turned his head. Through his eyes, the visitor saw the faded green carpet, the doctor's dull-black shoes, his socks, the legs of his trousers. Mersey's glance hovered there, around the doctor's knees. The visitor forced it higher, past the belt around a tidy waist, along the buttons of the opened vest to the white collar, and finally to the kindly eyes behind gold-rimmed glasses.

Again he had commanded this human being and had been obeyed. The traveler braced himself for the leap from the tortured mind to the sane one.

But his gaze continued to be that of Mersey.

The gray eyes of the doctor were on his patient. Intelligence and kindness were in those eyes, but the visitor could read nothing else.

He was caught, a prisoner in a demented mind. He felt panic. This must be the mind-screen he'd been warned about.

"Look down," the visitor commanded Mersey. "Shut your eyes. Don't let him see me."

But Mersey continued to be held by the doctor's eyes. The visitor cowered back into the crazed mental tangle.

Gradually, then, his fear ebbed. There was more likelihood that Cloyd did not believe Mersey's words than that he did. The doctor treated hundreds of patients and surely many of them had delusions as fanciful as this one might seem.

The traveler's alarm simmered down until he was capable of appreciating the irony of the situation.

But at the same time, he thought with pain, "Is it our fate that of all the millions of creatures on this world, we can establish communication only through the insane? And even then to have only imperfect control of the mind and, worse, to have it become a transmitter for our most secret thoughts?"
