"Dad," said Raych with some concern, "you look tired."
    "I dare say," said Hari Seldon, "I feel tired. But how are you?"
    Raych was forty-four now and his hair was beginning to show a bit of gray, but his mustache remained thick and dark and very Dahlite in appearance. Seldon wondered if he touched it up with dye, but it would have been the wrong thing to ask.
    Seldon said, "Are you through with your lecturing for a while?"
    "For a while. Not for long. And I'm glad to be home and see the baby and Manella and Wanda-and you, Dad."
    "Thank you. But I have news for you, Raych. No more lecturing. I'm going to need you here."
    Raych frowned. "What for?" On two different occasions he had been sent to carry out delicate missions, but those were back during the days of the Joranumite menace. As far as he knew, things were quiet now, especially with the overthrow of the junta and the reestablishment of a pale Emperor.
    "It's Wanda," said Seldon.
    "Wanda? What's wrong with Wanda?"
    "Nothing's wrong with her, but we're going to have to work out a complete genome for her-and for you and Manella as well-and eventually for the new baby."

    "No, you won over me and .     and Dors." (He had such trouble saying the name, even though four years had passed since her destruction.) "You won over Rashelle of Wye. You won over Jo-Jo Joranum. You won over Manella. How do you account for all that?"
    "Intelligence and charm," said Raych, grinning.
    "Have you thought you might have been in touch with their-our-minds?"
    "No, I've never thought that. And now that you mention it, I think it's ridiculous. -With all due respect, Dad, of course."
    "What if I told you that Wanda seems to have read Yugo's mind during a moment of crisis?"
    "Coincidence or imagination, I should say."
    "Raych, I knew someone once who could handle people's minds as easily as you and I handle conversation."
    "Who was that?"
    "I can't speak of him. Take my word for it, though."
    "Well-" said Raych dubiously.
