"I did have a rather bad night," Black said. "Association. Semantic instability." He felt the tentacle of thought that was sweeping across his mind.

"Well," Dodson said, his eyes probing from the screen, "it's obvious you know nothing of the Lawrence deal. Strange, though, since there's a record of a call placed to that office by Lawrence yesterday, and as far as we have been able to determine only you were there and only you could have answered. How do you explain that?"

Easy now! The block is most difficult to maintain when you're lying. Easy....

"There was a call," Black admitted, "from someone I don't know, a fellow who wanted Standskill. Wouldn't say why or give his name. The moment I told him Standskill was in Paris he said with some reluctance that he would have to contact another law firm. The caller was probably Lawrence. If you could describe him—"

"So Standskill's in Paris! The answering service didn't know that. Well, that rules him out. Thank you, Black. Are you sure you're all right?"

"Rather tired," Black said. "Overwork, I expect. The training is rather strenuous, and I do wish you wouldn't probe. As you found in psi school, my powers have a very delicate balance."

The probe withdrew hastily.

"Sorry, Black. Very sorry. Perhaps you need a rest. I'll be only too glad to send through an order—"

"Oh, thank you, sir," Black said, trying to make it sound fervent and properly subservient. He sent a thought of thankfulness after his words, a weak one. He must not appear too strong.

Dodson rang off.
