"But I'm the pilot—" Raf began and then realized that it was just that fact which had made the aliens attach him to the exploring party. If they believed that the Terran flitter was immobilized when he, and he alone, was not behind its controls, this was just the move they would make. But there they were wrong. Soriki might not be able to repair or service the motor, but in a pinch he could take it up, send it westward, and land it beside the spacer. Each and every man aboard the RS 10 had that much training.

Now the com-tech was scowling. He had grasped the significance of that arrangement as quickly as Raf. "How long do I wait for you, sir?" he asked in a voice which had lost its usual good-humored drawl.

And at that inquiry Captain Hobart showed signs of irritation. "Your suspicions are not founded on facts," he stated firmly. "These people have displayed no signs of wanting to harm us. And an attitude of distrust at this point might be fatal for future friendly contact. Lablet is sure that they have a highly complex society, probably advanced beyond Terran standards, and that their technical skills will be of vast benefit to us. As it happens we have come at just the right moment in their history, when they are striving to get back on their feet after a disastrous series of wars. It is as if a group of off-world explorers had allied themselves with us after the Burn-Off. We can exchange information which will be of mutual benefit."

"If any off-world explorers had set down on Terra after the Burn-Off," observed Soriki softly, "they would have come up against Pax. And just how long would they have lasted?"

Hobart had turned away. If he heard that half-whisper, he did not choose to acknowledge it. But the truth in the com-tech's words made an impression on Raf, a crew of aliens who had been misguided enough to seek out and try to establish friendly relations with the officials of Pax would have had a short and most unhappy shrift. If all the accounts of that dark dictatorship were true, they would have vanished from Terra, and not in their ships either. What if something like Pax ruled here? They had no way of knowing for sure.

Raf's eyes met Soriki's, and the com-tech's hand dropped to hook fingers in his belt within touching distance of his side arm. The flitter pilot nodded.

"Kurbi!" Hobart's impatient call sent him on his way. But there was some measure of relief in knowing that Soriki was left behind and that they had this slender link with escape.

He had tramped the streets of that other alien city. There there had been some semblance of habitation; here was abandonment. Earth drifted in dunes to half block the lanes, and here and there climbing vines had broken down masonry and had dislodged blocks of the paved sideways and courtyards.

The party threaded their way from one narrow lane to another, seeming to avoid the wider open stretches of the principal thoroughfares, Raf became aware of an unpleasant odor in the air which he vaguely associated with water, and a few minutes afterward he caught glimpses of the river between the buildings which fronted on it. Here the party turned abruptly at a right angle, heading westward once more, passing vast, blank-walled structures which might have been warehouses.

One of the aliens just ahead of Raf in the line of march suddenly swung around, his weapon pointing up, and from its nose shot a beam of red-yellow light which brought an answering shrill scream as a large, winged creature came fluttering down. The killer kicked at the crumpled thing as he passed. As far as Raf could see there had been no reason for that wanton slaying.
