"Why did you have to deliver that in person? What's wrong with using Communications?"

"It's not my province to ask questions, Dr. Wong. I was told to come here, and I was told to wait for a reply."

"Next Wednesday at ten? Let's see, this is Friday." David Wong pressed the key of his electronic calendar, but he had no need to study the dull green and red lights that flashed on to indicate the pattern of his day. He did not delude himself that he had any real choice, but he had learned in the past fifteen years that it kept up his courage to preserve at least the forms of independence. He allowed a decent thirty seconds to ponder the coded lights, then blanked the board and looked up with an easy smile.

"Dr. Wong's compliments to Leader Marley, and he will be honored to attend a conference on Wednesday at ten."

Nodding his head, Dr. Lanza glanced briefly around the office. "Queer, old-fashioned place you have here."

"Yes. It was built many years ago by a slippery old politician who wanted to be safe from his enemies. Makes a good place for Research, don't you think?"

Lanza did not answer. He strode to the door, then paused to look back.

"You understand, Dr. Wong, that I shall have to report the locked door? I have no choice."

"Has anyone?"

Officer Blagun followed his superior, leaving the door wide open behind them. Wong remained rigid in his chair until the clack of heels on marble floor had become a mere echo in his brain, then stretched out his hand to the intercom. He observed with pride that his hand did not tremble as he pressed the dial.
