I followed her slowly.

She passed through the arch, stopped, and turned her head toward the right, her eyes on something out of sight. She'd found him, but she saw me at the same time and her worry deepened.

When she moved back into the crowd, I strolled casually through the archway.

There was a vaguely defined passageway, the roof over it gone for half a million years, of course. And twenty feet away, oblivious of his surroundings except for what was directly in front of him, was my man.

His height and build were somewhat less than the norm. But it was his profile that drew my attention. A remarkable throwback; a throwback of a distinct type.

In fact, he might well have served as the model in the types textbooks labeled British. The resemblance was subtle. Only one trained to differentiate would ever have noticed it.

I let my attention take in his whole figure. His elbows had a habit of making fluttery movements when his exploring hands paused so that a strange birdlike impression was given. Also an air of ungainliness in the lines of the lean body, rather than the feline smoothness and grace of the norm-blend. It was so in keeping with his features that it served to strengthen the psycho diagnosis.

A throwback to an era ten thousand years in the past, and therefore, as the textbooks say, prone to mental instability. It was no wonder that the girl called Dotty had had the air of being perpetually worried!

She appeared now, from the far side of the ruin and approached the man.

He sensed rather than saw her and straightened up, every line of him etched with excitement.
