Again came the whisper of sandaled feet. Presently an Ammadian guard came into view, a heavy spear in one hand, a small torch of flaming wood in the other. The guard was peering into each of the cells across from Tharn, pausing at length at some, passing others quickly. Tharn wondered at the man's attempt at stealth; since it was impossible for any of the prisoners to get at him, such precautions could serve no evident ends. When the man reached a cell almost exactly across from Tharn, the cave man saw him toss something through the opening framing the bars. He heard the unseen prisoner sigh ... and then the guard raised his spear and inserted its head through the same opening. Tharn was on the point of crying out a warning, his reason dictated only by a desire to thwart as far as possible the hated symbol of authority represented by this white-tunicked assassin. But in that moment he saw a second figure steal into the outer periphery of light thrown by the torch--a figure of a man whom Tharn recognized instantly as one of those who had accompanied Jotan on his search for Dylara a few days before. As the arm holding the spear tensed to send it plunging into the unseen prisoner, the newcomer leaped cat-like upon the would-be assassin. There was a startled cry that echoed along the subterranean hall and the two men became a squirming knot of arms and legs. And then abruptly the threshing figures were still as the second man pressed the blade of a flint knife against the other's thinly clad back. "Not a move," growled Tamar, "or you are a dead man!" * * * * * Now a lovely dark-haired girl came into view, her face revealed by the flickering light of the still burning torch lying on the corridor's flooring. As she bent to pick up the bit of blazing wood Tharn recognized her as Urim's daughter, whose life he had saved on a long gone day. "What were you up to there?" growled Tamar. "Who are you and what----" "_Tamar!_" The cry came from behind the barred door from which the young nobleman had just drawn the cringing Sitab. There, framed in the barred opening, was Jotan! Alurna, a faint cry of happiness on her lips, rushed to the door and removed the heavy bar. Jotan bounded into the narrow hallway, gave Sephar's princess a thankful pat on the back, then turned to Tamar. "What's going on here? Who is this guard? How did you find me?" "First," Tamar said, "I'm going to find out why this son of Gubo was about to send a spear into you!" At Jotan's blank expression, Tamar explained what had been about to happen when he and Alurna arrived. Whereupon Jotan took the trembling Sitab by the front of his tunic and shook him until most of his breath was gone. "Who sent you?" Jotan snarled. "Speak before I strangle you with my bare hands!" "I dare not tell you! He would kill me!" Sitab cried through chattering teeth.
