Yes, he had not been mistaken. Lura’s brown ears showed again in outline against a moss-grown rock. She was waiting for him. He gathered his feet under him, and, as an arrow from a bow, he dashed out of cover and zigzagged down the slope. There was a single shout of surprise from behind and then he was into the woods, Lura with him.

Now he was absorbed in the task at hand. He burst through a screen of small trees, making only the most elementary effort to hide his trail. Lura’s warning that they were now followed set his heart to pounding. Now -now it was just his own two feet, his hunting lore, and his sense of direction against all the cunning of the enemy. He must be a tempting morsel always just about to fall into the pursuers’ hands, and yet he must keep from capture and lead the run into Plains territory so that Can-trul might be provoked into action. As Jarl had outlined it the plan was as simple as it was deadly-but was it going to work?

There were short periods during the rest of the day when he could snatch some rest, always after Lura assured him that something still ran the trail behind. Once he dared verify that for himself, having climbed a cliff after crossing a stream. He lingered in a shallow crevice at the top long enough to see three gray shapes come out of the woods a half mile back, the first on all fours sniffing the ground as it came.

Three-out of how many? But the beacon must have warned the camp. He must think of nothing else now but his own task. If ever his eyes and ears served him well” they must do better than that now. As a fugitive gaining his second wind perhaps he would dare display a little more cunning. The Beast Things might accept the idea that sheer panic had brought him away from the beacon, but that would not prevent a greater show of caution now. He tried several of the simpler trail-hiding tricks and waited for Lura’s verdict. It was favorable, the chase was still on.

Some hours before evening he struck west, trying to intercept a line which must run to the beaver lake and so to CantruTs camp-unless the fire had driven the Plainsmen from that base. He ate as he went, berries and handfuls of ripe grain pulled from the ragged self-sown patches in the old fields. There were hard, half-ripe peaches in an old orchard he pounded through and he had enough to keep him going when washed down with water from brook and spring.

The night was the worst. He had to lay up for rest, swinging into the branches of a tree, close enough to an outcrop of rock to be able to leap away if the need came. Lura catnapped on that rock, her brown and cream melting into the weathered stone. He dozed and woke, to stretch cramped muscles and doze again. Before morning he moved twice, putting a mile between each resting place and choosing each for the ability to make a quick retreat.

When the gray of dawn caught him again he was lying flat on a bluff overhanging a stream he was sure was the outlet of the beaver lake. Pieces of charred wood caught among the boulders below proved that. The size of the stream had dwindled, perhaps the beavers had started repairs in the broken dam. Fors lay there, every aching joint, every exhauusted muscle protesting the move he was willing his body into making. It was as if he had been running for days-since they had left the ruined city they had been on the move with little or no rest. And none to look for in the immediate future either-

Luckily he was facing downstream, with his eyes on the moving surface, for now he saw what might have been the strangest sight to ever appear on that forgotten shore. An animal was swimming up river, nosing along the bank in a peculiar fashion, almost as if it were intelligently questing. When it reached the spot between two stones where Fors had knelt to drink before he climbed, it scrambled out of the water and sat up on its haunches, its forepaws held close to its lighter underbelly, its head high with sniffing nose testing the flowing air currents.

It was a rat-one of the huge, gray-coated ones of the old breed with which man has fought eternal warfare since the first days of time. A rat-Fors remembered back to the sunny morning in the ruins of the old city shops when just such a beast had sat to watch him without alarm. The rats flourished in the cities-everyone knew that. But for the most part men did not see them-even there. Their ways were underground, in the noisome burrows they had hollowed and claimed from cellar to cellar, through the old sewers and waterways.

The rat shook itself. Then the growing light brought a flash from its throat as it raised higher its head. A metal collar-surely that was a metal collar. But a collar on a rat-why-who-
