Danchekker turned abruptly and began walking back toward the door, reciting statistics on the density of body hair and the thickness of subdermal layers of fat, apparently having dismissed the incident from his mind. Hunt paused to survey the body once more before turning to follow, and in doing so, he caught Gray's eyes for an instant. The engineer's mouth twitched briefly at the corners; Hunt gave a barely perceptible shrug. Caldwell, still standing by the foot of the table, observed the brief exchange. He turned his head to look after Danchekker and then back again at the Englishmen, his eyes narrowing thoughtfully. At last he fell in a few paces behind the group, nodding slowly to himself and permitting a faint smile.

The door slid silently into place and the room was once more plunged into darkness.

Chapter Seven

Hunt brought his hands up to his shoulders, stretched his body back over his chair, and emitted a long yawn at the ceiling of the laboratory. He held the position for a few seconds, and then collapsed back with a sigh. Finally he rubbed his eyes with his knuckles, hauled himself upright to face the console in front of him once more, and returned his gaze to the three-foot-high wall of the cylindrical glass tank by his side.

The image of the Trimagniscope tube was an enlarged view of one of the pocket-size books found on the body, which Danchekker had shown them on their first day in Houston three weeks before. The book itself was enclosed in the scanner module of the machine, on the far side of the room. The scope was adjusted to generate a view that followed the change in density along the boundary surface of the selected page, producing an image of the lower section of the book only; it was as if the upper part had been removed, like a cut deck of cards. Because of the age and condition of the book, however, the characters on the pages thus exposed tended to be of poor quality and in some places were incomplete. The next step would be to scan the image optically with TV cameras and feed the encoded pictures into the Navcomms computer complex. The raw input would then be processed by pattern recognition techniques and statistical techniques to produce a second, enhanced copy with many of the missing character fragments restored.

Hunt cast his eye over the small monitor screens on his console, each of which showed a magnified view of a selected area of the page, and tapped some instructions into his keyboard.

"There's an unresolved area on monitor five," he announced. "Cursors read X, twelve hundred to thirteen eighty; Y, nine ninety and, ah, ten seventy-five."

Rob Gray, seated at another console a few feet away and almost surrounded by screens and control panels, consulted one of the numerical arrays glowing before him.

"Z mod's linear across the field," he advised. "Try a block elevate?"
