That feeling of being watched made him cautious, so he did not practice much with his mind-control on any of the pigeon-like birds! He did, however, make a trip to the local zoo, and as he paused momentarily in front of each of the cages to look at the exhibit it contained, he briefly made an excursion into the mind of each different type of animal, bird or rodent. Outside of minor differences of texture, they all seemed about the same. Each of them had, naturally, different muscular abilities that would need considerable study if he ever intended using one of them. And every minute he was seeking, searching for any tiniest thread of evidence as to what it was that was causing this undercurrent of secret intrigue that was so plainly evident to his super-sensitive mind. But there was no factual data to be learned. Only that "feel" of it in the very air. Yet as the day wore on he came to believe that much or most of what he sensed was not that plot which was causing the Corps concern. Rather, it seemed more as though all the people here were engaged in some sort of secret aggressiveness. And it was finally forced into his consciousness that it was "business," not "politics." For it was well-known that Simonides, even though it had become the Federation's wealthiest world, was not yet satisfied ... that its merchants and traders wanted to capture more and still more of the System's business. There were far too many minds engaged in aggressive thoughts for a political revolution, he felt sure. If it was this wide-spread, surely others of the Corps of the Secret Service would have found out something definite about it. No, whatever this was, it distinctly was not what he was here to find. The feeling that he was being spied upon was always more or less present, but he could not spot the man or men who were watching him. Either several were working in short shifts, or else the trailer kept so far behind him that the multiplicity of thoughts from the hundreds of people always around masked those of the spy. Hanlon ate a leisurely lunch in a small restaurant, and during the afternoon continued his apparently-aimless sight-seeing. If they were shadowing him, they would have nothing to report, he grinned. Not during the day, at least. What the evening would bring forth would perhaps be another matter. For he had determined to at least get in touch with the SS man who had written that note. He would have dinner at the Golden Web, if they served meals. If not, he would have a drink anyway. The two men certainly should know each other by sight. He went briefly to the hotel, but there had been no calls for him. So he took a ground-cab to the cafe, which turned out to be a pretentious, garish one. Inside he made his way to that part of the long, busy bar presided over by a slim, blond man. Hanlon climbed onto a stool. "Gimme a good old Kentucky mint-julep, suh," he demanded, "an' be doggoned suah it's made right."
