Lura’s scream tore through the air drowning out the warning he shouted. The bushes threshed wildly at her attack. But she had had her instructions, not to kill now -only to harry and drive. The black thing snapped up out of hiding, arms flailing as the men around Fors went to their knees, arrows ready on strings. A cloud of feathered shafts flew. Most, Fors guessed, had fallen woefully short. Shooting up slope was always a tricky business.

The Beast Thing scuttled away over the crown of the hill at a desperate speed. And it was gone before other arrows could follow the first volley. Arskane edged along the line of disappointed archers to join Fors.

“Was that a scout?” he asked.

“Could be. They have always hunted in packs before. If it was a scout, it will now report.”

Arskane chewed the tip of his thumb thoughtfully. Fors knew the worries which plagued him now. Ambush-that was the worst fear. They knew so little of the tactics of the Beast Things-but lying in wait in the dark seemed to fit the nature of the foul creatures best. In the ruined cities they had always fought from cover when they could.

In the end Arskane did as Fors thought he would, gave the signal to push on until they reached the boundaries of their beat, one of the hills where the beacon had been heaped some days before. So they crawled on. Lura flanking the line of march. And they reached the beacon hill without interference. Once there, Arskane formally relieved the guard on duty.

The hour was close to dawn. A thin gray light gave ordinary trees and bushes a queer new life as if they were now cut off from the real world by some flimsy barrier. The beacon keepers had torn out or hacked away most of the brush and saplings, so that the crown of the hill was bare and one could see for a good range on all sides.

Fors located the camp by the river first and then set about noting other landmarks which might help him keep the proper course if he decided to make the break north soon. The men whom they had relieved were marching in fairly good order down the hill, ready to drop into the protection of the road ditch, when the last one in that line threw up his arms with a startled jerk and fell without a sound. The man nearest him spun around just in time to see him fall and started back to his aid, only to choke and go to his knees tearing at the dart quivering in his own throat.

They broke and ran back. But before they could reach the miserable shelter afforded by the beacon, two more died, Beast Thing steel in their contorted bodies. Only one lived to break through to the men above.

And they, arrows ready, stood cursing, unable to shoot at a foe which would not show itself.
