Alten rose sharply to his feet. "A cripple named Tugh?"

"Yes," she affirmed wonderingly. "Does it mean anything to you?"

Alten swung on me. "What is the number of that house on Patton Place? Did you happen to notice?"

I had, and wondering I told him.

"Just a minute," he said. "I want to use the phone."

He came back to us in a moment: his face was very solemn. "That house on Patton Place is owned by a man named Tugh! I just called a reporter friend; he remembers a certain case: he confirmed what I thought. Mistress Mary, did this Tugh in your Time ever consult doctors, trying to have his crippled body made whole?"

"Why, of course he did. I have heard that many times. But his crippled, deformed body cannot be cured."

Alten checked Larry and me when we would have broken in with astonished questions. He said:

"Don't ask me what it means; I don't know. But I think that this cripple—this Tugh—has lived both in 1777 and 1935, and is traveling between them in this Time-traveling cage. And perhaps he is the human master of that Robot."

Alten made a vehement gesture. "But we'd better not theorize; it's too fantastic. Here is the story of Tugh in our Time. He came to me some three years ago; in 1932, I think. He offered any price if I could cure his crippled body. All the New York medical fraternity knew him. He seemed sane, but obsessed with the idea that he must have a body like other men. Like Faust, who, as an old man, paid the price of his soul to become youthful, he wanted to have the beautiful body of a young man."
