ever came to him, the story of what they thought they saw.
But they didn't laugh.
She could read that in the fury in Gladys Claffern's eyes; in the false sparkle of her words; in her desire to leave early. And as she parted with them, she caught one last, anonymous whisper-disjointed.
"... never saw anything like... so handsome-"
And she knew what it was that had enabled her to finger-snap them so. Let each cat mew; and let each cat know-that she might be prettier than Claire Belmont, and grander, and richer-but not one, not one, could have so handsome a lover!
And then she remembered again-again-again, that Tony was a machine, and her skin crawled.
"Go away! Leave me be!" she cried to the empty room and ran to her bed. She wept wakefully all that night and the next morning, almost before dawn, when the streets were empty, a car drew up to the house and took Tony away.
Lawrence Belmont passed Dr. Calvin's office, and, on impulse, knocked. He found her with Mathematician Peter Bogert, but did not hesitate on that account.
He said, "Claire tells me that U.S. Robots paid for all that was done at my house-"
"Yes," said Dr. Calvin. "We've written it off, as a valuable and necessary part of the experiment. With your new position as Associate Engineer, you'll be able to keep it up, I think."
"That's not what I'm worried about. With Washington agreeing to the tests, we'll be able to get a TN model of our own by next year, I think." He turned hesitantly, as though to go, and as hesitantly turned back again.
"Well, Mr. Belmont?" asked Dr. Calvin, after a pause.
"I wonder-" began Larry. "I wonder what really happened there. She- Claire, I mean-seems so different. It's not just her looks-though, frankly, I'm amazed." He laughed nervously. "It's her! She's not my wife, really-I can't explain it."
"Why try? Are you disappointed with any part of the change?"
"On the contrary. But it's a little frightening, too, you see-"
"I wouldn't worry, Mr. Belmont. Your wife has handled herself very well. Frankly, I never expected to have the experiment yield such a thorough and complete test. We know exactly what corrections must be made in the TN model, and the credit belongs entirely to Mrs. Belmont. If you want me to be very honest, I think your wife deserves your promotion more than you do."
Larry flinched visibly at that. "As long as it's in the family," he murmured unconvincingly and left.
Susan Calvin looked after him, "I think that hurt-I hope... Have you read Tony's report, Peter?"
"Thoroughly," said Bogert. "And won't the TN-3 model need changes?"
"Oh, you think so, too?" questioned Calvin sharply. "What's your reasoning?"
Bogert frowned. "I don't need any. It's obvious on the face of it that we can't have a robot loose which makes love to his mistress, if you don't mind the pun."
"Love! Peter, you sicken me. You really don't understand? That machine had to obey the First Law. He couldn't allow harm to come to a human being, and harm was coming to Claire Belmont through her own sense of inadequacy. So he made love to her, since what woman would fail to appreciate the compliment of being able to stir passion in a machine-in a cold, soulless machine. And he opened the curtains that night deliberately, that the others might see and envy-without any risk possible to Claire's marriage. I think it was clever of Tony-"
"Do you? What's the difference whether it was pretense or not, Susan? It still has its horrifying effect. Read the report again. She avoided him. She screamed when he held her. She didn't sleep that last night-in hysterics. We can't have that."
"Peter, you're blind. You're as blind as I was. The TN model will be rebuilt entirely, but not for your reason. Quite otherwise; quite otherwise. Strange that I overlooked it in the first place," her eyes were opaquely thoughtful, "but perhaps it reflects a shortcoming in myself. You see, Peter, machines can't fall in love, but-even when it's hopeless and horrifying- women can!"

United States Robots and Mechanical Men Corporation had a problem. The problem was people.
Peter Bogert, Senior Mathematician, was on his way to Assembly when he encountered Alfred Lanning, Research Director. Lanning was bending his ferocious white eyebrows together and staring down across the railing into the computer room.
On the floor below the balcony, a trickle of humanity of both sexes and various ages was looking about curiously, while a guide intoned a set speech
