He was puzzled. By the signs, the deer had been fleeing for its life and yet whatever menaced it had left no trace. But Fors was not afraid. He had never met any living thing, man or animal, which could stand against the force of his steeltipped arrows or which he would have hesitated to face, short sword in hand.

Between the men of the mountains and the roving Plainsmen there was a truce. The Star Men often lived for periods of time in the skin-walled tents of the herders, exchanging knowledge of far places with those eternal wanderers. And his father had taken a wife among tine outlanders. Of course, there was war to the death between the humankind and the Beast Things which skulked in the city ruins. But the latter had never been known to venture far from their dank, evil-smelling burrows in the shattered buildings, and certainly one need not fear meeting with them in this sort of open country! So he followed the trail with a certain reckless disregard.

The trail ended suddenly on the tip of a small gully. Some ten feet or so below, a stream—swollen by the rain —frothed around green-grown rocks. Lura was on her belly, pulling her body forward along the rim of the ravine. Fors dropped down and inched behind a bush. He knew better than to interfere with her skilled approach.

When the tip of her brown tail quivered he watched for a trembling of Lura’s flanks which would signalize her spring. But instead the tail suddenly bristled and the shoulders hunched as if to put a brake upon muscles already tensed. He caught her message of bewilderment, of disgust and, yes, of fear.

He knew that he had better eyesight than almost all of the Eyrie men, that had been proved many times. But what had stopped Lura in her tracks was gone. True, upstream a bush still swayed as if something had just pushed past it. But the sound of the water covered any noise and although he strained—there was nothing to see.

Lura’s ears lay flat against her skull and her eyes were slits of blazing rage. But beneath the rage Fors grasped another emotion—almost fear. The big cat had come across something strange and therefore to be considered with suspicion. Aroused by her message Fors lowered himself over the edge of the gully. Lura made no attempt to stop him. Whatever had troubled her was gone, but he was determined to see what traces it might have left in its passing.
