"We don't believe that's necessarily so. A lot of information is simply not conveyed in civilian broadcasts, and certainly not in military broadcasts."

"They can type us down to our toenails just by the fact that we still broadcast analog radio waves," Harry said, not moving from the window.

"Yes, sir, but—"

"Your warnings are well taken, Lieutenant Dreyer," Arthur said. "But we can't get anywhere unless we examine the Guest. If this means some two-way exchanges, so be it. If the Guest is a conduit to the ship, we might be able to learn how through the exams."

"It's an interesting idea," Harry conceded in an undertone.

"Yes, sir," Dreyer said. "I've been told to pass these on to you—your itineraries for the Commander in Chiefs visit. We're at your disposal."

"All right. Let's have two-way back on." Arthur walked down the slightly sloping floor to the window and stood beside Harry. He pushed the button activating the intercom to the Guest's chamber.

"Excuse me. We'd like to continue our questions and examinations."

"Yes," the Guest said, pushing aside the blankets and standing slowly.

"What is the state of your health?" Arthur asked. "Are you feeling well?"

"Not altogether well," the Guest said. "The food is adequate, but not sustaining."

The Guest had been allowed to choose between a variety of carefully prepared "soups." The first tissue samples had revealed that the Guest could conceivably digest dextro-rotary sugars and proteins generally found in Earth life forms. Purified water was being supplied in beakers passed through with the "food." Thus far, the Guest had not excreted anything into the wide stainless-steel sample tray left open in another corner. The Guest had eaten sparingly, and without apparent enthusiasm.

"Can you describe substances that would please you?"

"In space, we hibernated—"

Harry emphasized the "we" in his notepad.

"And our nutrition was provided by synthesizing machines throughout the voyage."

Arthur blinked. Harry scribbled furiously.

"I am not aware of the names of substances in this language to describe them. The food you provide seems adequate."

"But not enjoyable."

The Guest didn't respond.

"We'd like to conduct another physical examination," Arthur said. "We are not going to take any more tissue samples."

The Guest withdrew its three brown eyes and then produced them again, but said nothing, standing in what might have been a dejected posture—if the Guest could feel dejected, and if body language was at all similar . . .

"You do not have to cooperate," Arthur said. "We don't want to force anything on you."

"Difficulties with speaking, with language," the Guest said. It stepped sideways in one fluid motion to the far right corner of the room. "There are questions you do not ask. Why?"

"I'm sorry, I don't understand."

"You do not ask questions about interior thoughts."

"You mean, what you are thinking?"

"Interior states are far more important than physical construction, are they not? Is this not true for your intelligences?"
