Of the symbols contained in the documents, numerals were the first to be identified. A team of cryptographers, assembled at Navcomms HQ, soon worked out the counting system, which turned out to be based on twelve digits rather than ten and employed a positional notation with the least significant digit to the left. Deciphering the nonnumeric symbols was proving more difficult. Linguists from institutions and universities in several countries had linked into Houston and, with the aid of batteries of computers, were attempting to make some sense of the language of the Lunarians, as Charlie's race had come to be called in commemoration of his place of discovery. So far their efforts had yielded little more than that the Lunarian alphabet comprised thirty-seven characters, was written horizontally from right to left, and contained the equivalent of upper-case characters.

Progress, however, was not considered to be bad for so short a time. Most of the people involved were aware that even this much could never have been achieved without the scope, and already the names of the two Englishmen were well-known around the division. The scope attracted a lot of interest among the UNSA technical personnel, and most evenings saw a stream of visitors arriving at the Ocean Hotel, all curious to meet the coinventors of the instrument and to learn more about its principles of operation. Before long, the Ocean became the scene of a regular debating society where anybody who cared to could give free rein to his wildest speculations concerning the Charlie mystery, free from the constraints of professional caution and skepticism that applied during business hours.

Caldwell, of course, knew everything that was said by anybody at the Ocean and what everybody else thought about it, since Lyn Garland was present on most nights and represented the next best thing to a hot line back to the HQ building. Nobody minded that much—after all, it was only part of her job. They minded even less when she began turning up with some of the other girls from Navcomms in tow, adding a refreshing party atmosphere to the whole proceedings. This development met with the full approval of the visitors from out-of-town; however, it had led to somewhat strained relationships on the domestic front for one or two of the locals.

Hunt jabbed at the keyboard for the last time and sat back to inspect the image of the completed page.

"Not bad at all," he said. "That one won't need much enhancement."

"Good," Gray agreed. He lit a cigarette and tossed the pack across to Hunt without being asked. "Optical encoding's finished," he added, glancing at a screen. "That's number sixty-seven tied up." He rose from his chair and moved across to stand beside Hunt's console to get a better view of the image in the tank. He looked at it for a while without speaking.

"Columns of numbers," he observed needlessly at last. "Looks like some kind of table."
