The creature was slow, but its feet were fast. The fifth fall came down on the running figure, and Slaker was gone.

The quinquepedalian hesitated, one foot raised, searching. It was aware of them; it would not allow the killers of its child to escape. The eye roved, socketless, its glassy stare directed by a slow twisting of the foot. The circle of filaments combed the air, feeling for a sound or smell, or whatever trace of the fugitives they were adapted to detect.

After a few minutes the eye closed and the fibrils withdrew. The foot went high; plummeted. The earth rocked with the force of the blow. It lifted again, to smash down a few feet over, leaving a tangent print.

After a dozen such stomps the creature reversed course and came back, making a second row ahead of the first. This, Tinnerman realized, was carpet-bombing; and the two men were directly in the swath.

If they ran, the five-footed nemesis would cut them down easily. If they stayed, it would get them anyway, unless one or both of them happened to be fortunate enough to fit into the diamond between four prints. The odds were negative. And quite possibly it would sense a near miss, and rectify the error with a small extra tap.

They waited, motionless, while it laid down another barrage, and another. Now it was within fifty feet, mechanically covering the area. Behind it a flat highway was developing.

Saturation stomping, Tinnerman thought, and found the concept insanely funny. Man discovers a unique five-footed monster—the Quink—and it steps on him. Would the history books record the irony?

He saw the answer. He gave a cry and lurched to his feet, flinging his pack aside and plunging directly at the monster.

The foot halted, quite fast on the uptake, and rotated its eye to cover him. It gathered itself, crashed down, an irresistible juggernaut. The earth jumped with its fury; but Tinnerman, running in an unexpected direction, had passed its arc.
