From the alien ship emerged a second party. The Throg in their midst was unarmed and limping. Although to Terran eyes one alien was the exact counterpart of the other, Shann thought that this one was the prisoner in the skull cave. Yet the indications now suggested that he had only changed one captivity for another and was in disgrace among his kind. Why? The Throg limped up to front the leader with the translator, and his guards fell back. Again mandibles clicked, were answered, though the sense of that exchange eluded Shann. At one point in the report--if report it was--he himself appeared to be under discussion, for the injured Throg waved a hand-claw in the Terran's direction. But the end to the conference came quickly enough and in a manner which Shann found shocking. Two of the guards stepped forward, caught at the injured Throg's arms and drew him away, leading him out into a space beyond the grounded ship. They dropped their hold on him, returning at a trot. The officer clicked an order. Blasters were unholstered, and the Throg in the field shriveled under a vicious concentration of cross bolts. Shann gasped. He certainly had no liking for Throgs, but this execution carried overtones of a cold-blooded ferocity which transcended anything he had known, even in the callous brutality of the Dumps. Limp, and more than a little sick again, he watched the Throg officer turn away. And a moment later he was forced along in the other's wake to the domes of the once Terran camp. Not just to the camp in general, he discovered a minute later, but to that structure which had housed the com unit linking them with ships cruising the solar lanes and with the patrol. So Thorvald had been right; they needed a Terran to broadcast--to cover their tracks here and lay a trap for the transport. Shann had no idea how much time he had passed among the Wyverns; the transport with its load of unsuspecting settlers might already be in the system of Circe, plotting a landing orbit around Warlock, broadcasting her recognition signal and a demand for a beam to ride her in. Only, this time the Throgs were out of luck. They had picked up one prisoner who could not help them, even if he wanted to do so. The mysteries of the highly technical installations in this dome were just that to Shann Lantee--complete mysteries. He had not the slightest idea of how to activate the machines, let alone broadcast in the proper code. A cold spot of terror gathered in his middle, spreading outward through his smarting body. For he was certain that the Throgs would not believe that. They would consider his protestations of ignorance as a stubborn refusal to co-operate. And what would happen to him then would be beyond human endurance. Could he bluff--play for time? But what would that time buy him except to delay the inevitable? In the end, that small hope based on his momentary contact with Thorvald made him decide to try that bluff.
