"I hope you don't mind," said Greg. "I've been wanting to have a talk with you."
Craven leaped to his feet, his eyes shining. "Three dimensions!" he whispered. "How did you do it?"
Greg chuckled. "I haven't patented the idea, Doctor. I'd rather not tell you just now."
"You will accept my congratulations, however?" asked Craven.
"That's generous of you. I really hadn't expected this much."
"I mean it," said Craven. "Damned if I don't." Chambers was on his feet, leaning across the desk, with his hand held out. Greg's right hand came out slowly.
"Sorry, I really can't shake hands," he said. "I'm not here, you know. Just my image."
Chambers' hand dropped to the desk. "Stupid of me not to realize that. You looked so natural." He sat back in his chair again, brushed his gray mustache. A smile twisted his lips. "So you've been watching me?"
"Off and on," Greg said.
"And what is the occasion of this visit?" asked Chambers. "You could have held a distinct advantage by remaining unseen. I didn't entirely believe what Craven told me, you know."
