For that matter, what was the purpose of Travelers Aid Bureau? It was a front for another kind of activity. Philanthropy had nothing to do with it. If he still had possession of Dimanche, he'd be able to find out. Everything seemed to hinge on that. With it, he was nearly a superman, able to hold his own in practically all situations--anything that didn't involve a Huntner woman, that is. Without it--well, Tunney 21 was still far away. Even if he should manage to get there without it, his mission on the planet was certain to fail. He dismissed the idea of trying to recover it immediately from Murra Foray. She was an audio-sensitive. At twenty feet, unaided, she could hear a heartbeat, the internal noise muscles made in sliding over each other. With Dimanche, she could hear electrons rustling. As an antagonist she was altogether too formidable. * * * * * He began pulling on his clothing, wincing as he did so. The alternative was to make another Dimanche. _If_ he could. It would be a tough job even for a neuronic expert familiar with the process. He wasn't that expert, but it still had to be done. The new instrument would have to be better than the original. Maybe not such a slick machine, but more comprehensive. More wallop. He grinned as he thought hopefully about giving Murra Foray a surprise. Ignoring his aches and pains, he went right to work. With money not a factor, it was an easy matter to line up the best electronic and neuron concerns on Godolph. Two were put on a standby basis. When he gave them plans, they were to rush construction at all possible speed. Each concern was to build a part of the new instrument. Neither part was of value without the other. The slow-thinking Godolphians weren't likely to make the necessary mental connection between the seemingly unrelated projects. He retired to his suite and began to draw diagrams. It was harder than he thought. He knew the principles, but the actual details were far more complicated than he remembered. Functionally, the Dimanche instrument was divided into three main phases. There was a brain and memory unit that operated much as the human counterpart did. Unlike the human brain, however, it had no body to control, hence more of it was available for thought processes. Entirely neuronic in construction, it was far smaller than an electronic brain of the same capacity. The second function was electronic, akin to radar. Instead of material objects, it traced and recorded distant nerve impulses. It could count the heartbeat, measure the rate of respiration, was even capable of approximate analysis of the contents of the bloodstream. Properly focused on the nerves of tongue, lips or larynx, it transmitted that data back to the neuronic brain, which then reconstructed it into speech. Lip reading, after a fashion, carried to the ultimate. Finally, there was the voice of Dimanche, a speaker under the control of the neuronic brain.
