Braithwaite ignored the sarcasm and said, “Would you really like to know that it was your imagination, or would you rather not be sure? Think very carefully before you answer.
“If I’m imagining things,” said Hewlitt sharply, “I don’t want to be the only one who doesn’t know it.”
“Fair enough,” Braithwaite replied. “How well do you remember that tree you say you climbed on Etla, and the appearance of the fruit you may have eaten?”
“Well enough to draw a picture of it,” said Hewlitt, “if I could draw. Do you want me to try?”
“No,” the psychologist replied. He leaned sideways until he could reach the communicator keyboard with one hand and tapped briefly. When the screen lit up with the Sector General emblem, he said, “Library, nonmedical, vocal input, visual and translated vocal output, subject former Etlan Empire, planet Etla the Sick.”
“Please wait,” said the cool, impersonal voice of the library computer.
Surprised, Hewlitt said, “I didn’t know I could get the library on that thing, just the nurses’ station and the so-called entertainment channels.”
“Without the correct access codes, you can’t,” said Braithwaite. “But if you ever feel so bored that you want to browse, I could probably get you authorization. You won’t be given the codes for the medical library, though. When a case is thought to include a degree of hypochondria, the patient concerned should not be allowed access to a virtually unlimited number of symptoms.”
Hewlitt laughed suddenly in spite of himself and said, “I can understand why.”
Before Braithwaite could respond, the library voice said, “Caution. The Etla data is accurate but not yet complete. Following the large-scale police action taken against the then-Etlan Empire by the Monitor Corps, and the subsequent acceptance of its planets as members of the Galactic Federation twenty-seven standard years ago, the required transfer of Etlan botanical information to Central Records has been given a low order of priority owing to an intervening period of social unrest. The current situation is stable, the native intelligent life-form is physiological classification DBDG and nonhostile, and visits by other Federation citizens are encouraged. Please state your area of interest.”
A large-scale police action, Hewlitt thought. There had been a savage and mercifully short interstellar war fought between the Etlan Empire and the Federation, brought about by the need of the ruling group to maintain itself in power while diverting the attention of its citizens from its own shortcomings. But the function of the Monitor Corps was to maintain the Federation’s peace and not fight wars, so the response to the Etlan invasion of a whole galactic sector was a police action rather than a war. The fact that peace and stability had returned to the Etlan worlds meant that the Federation had won it.
“Etlan native flora,” said Braithwaite, interrupting Hewlitt’s cynical train of thought. “Specifically, a listing of all large fruitbearing trees, ten meters tall or higher, found in the south temperate zone. Display for twenty seconds’ duration unless requested otherwise.”
For some reason Hewlitt was beginning to feel uneasy. He looked at Braithwaite and opened his mouth to speak, but the lieutenant shook his head, pointed at the viewscreen, and said, “You described your tree as being very tall, but it may have looked tall because at the time you were a very small child. I thought it better to start with ten meters.”
It was like one of his childhood botany lessons, Hewlitt thought, a steady succession of tree pictures which in the present situation he found anything but boring. Most of them were strange to him, both in shape and foliage and in the fruit they bore, while others resembled the large bushes he had seen growing outside the garden fence. But one of them …
“That’s it!” he said.
“Hold: replay and expand data on the Pessinith tree,” said Braithwaite into the communicator. Then he said to Hewlitt, “It certainly looks like the tree you described: thick, twisted branches, with four thinner ones without bark at the top bearing the fruit clusters. And the color of the foliage is right for late summer when you climbed it. Library, run and repeat close-ups of the fruit showing seasonal growth and color changes.”
