Yet they were important. Some of them had been cut off close to the sand. Not broken by any natural cause, but cut sharply and squarely by a knife or blade of some sort. The cut plants were long dried and dead, but a tiny hope flared up in him. This was the first sign that other people were actually alive on this heat-blasted planet. And whatever the plants had been cut for, they might be of aid to him. Food—perhaps drink. His hands trembled at the thought as he dropped Lea heavily into the shade of the rock. She didn’t stir.

His knife was sharp, but most of the strength was gone from his hands. Breath rasping in his dried throat, he sawed at the tough stem, finally cutting it through. Raising up the shrub, he saw a thick liquid dripping from file severed end. He braced his hand against his leg, so it wouldn’t shake and spill, until his cupped palm was full of sap.

It was wet, even a little cool as it evaporated.

Surely it was mostly life-giving water. He had a moment’s misgiving as he raised it to his lips, and instead of drinking it merely touched it with the tip of his tongue.

At first nothing—then a searing pain. It stabbed deep into his throat and choked him. His stomach heaved and he vomited bitter bile. On his knees, fighting the waves of pain, he lost body fluid he vitally needed.

Despair was worse than the pain. The plant juice must have some use; there must be a way of purifying it or neutralizing it. But Brion, a stranger on this planet, would be dead long before he found out how to do this.

Weakened by the cramps that still tore at him, he tried not to realize how close to the end he was. Getting the girl on his back seemed an impossible task, and for an instant he was tempted to leave her there. Yet even as he considered this he shouldered her leaden weight and once more went on. Each footstep an effort, he followed his own track up the dune. Painfully he forced his way to the top, and looked at the Disan standing a few feet away.
