The wind had turned cool. Michaelson shivered, wishing he had brought a coat. The city was absolutely still except for small gusts of wind sighing through the frail spires. The ancient book still lay in the sand beside the dark spot of blood. He stooped over and picked it up.

It was light, much lighter than most Earth books. He ran a hand over the binding. Smooth it was, untouched by time or climate. He squinted at the pages, tilting the book to catch the bright moonlight, but the writing was alien. He touched the page, ran his forefinger over the writing.

Suddenly he sprang back. The book fell from his hands.

"God in heaven!" he exclaimed.

He had heard a voice. He looked around at the old buildings, down the length of the ancient street. Something strange about the voice. Not Maota. Not his tones. Not his words. Satisfied that no one was near, he stooped and picked up the book again.

"Good God!" he said aloud. It was the book talking. His fingers had touched the writing again. It was not a voice, exactly, but a stirring in his mind, like a strange language heard for the first time.

A talking book. What other surprises were in the city? Tall, fragile buildings laughing at time and weather. A clock measuring God-knows-what. If such wonders remained, what about those already destroyed? One could only guess at the machines, the gadgets, the artistry already decayed and blown away to mix forever with the sand.

I must preserve it, he thought, whether Maota likes it or not. They say these people lived half a million years ago. A long time. Let's see, now. A man lives one hundred years on the average. Five thousand lifetimes.

And all you do is touch a book, and a voice jumps across all those years!

He started off toward the tall building he had examined upon discovery of the city. His left eyelid began to twitch and he laid his forefinger against the eye, pressing until it stopped. Then he stooped and entered the building. He laid the book down and tried to take the "clock" off the wall. It was dark in the building and his fingers felt along the wall, looking for it. Then he touched it. His fingers moved over its smooth surface. Then suddenly he jerked his hand back with an exclamation of amazement. Fear ran up his spine.
