of the wood and entered the dry gully beyond, it was not to be seen; but as we reached the bottom and began to climb the farther side, it emerged from the trees, more ragged than ever.
For the space of a prayer it seemed to have lost sight of us, soaring at an angle to our own path, then swooping toward us again in a long, flat glide. I had Terminus Est clear of her sheath, and I neck-reined the black between the flying thing and Jonas.
Swift though our destriers were, it came far more swiftly. If I had possessed a pointed blade, I think I could have spitted it as it dove; had I done so I would surely have perished. As it was, I caught it with a two-handed stroke. It was like cutting air, and I thought the thing too light and tough for even that bitter edge. An instant later it parted like a rag; I felt a brief sensation of warmth, as though the door of an oven had been opened, then soundlessly shut.
I would have dismounted to examine it, but Jonas shouted and waved. We had left the lofty forest about Saltus far behind, and were entering a broken country of steep hills and ragged cedars. A grove of these stood at the top of the slope; we plunged into their tangled growth like madmen, flattened against the necks of our mounts.
Soon the foliage grew so thick they could move no faster than a walk. Almost at once we reached a sheer rock face and were forced to halt. When we were no longer smashing through the tangled limbs, I could hear something else behind us—a dry rustling, as though a wounded bird were fluttering among the treetops. The medicinal fragrance of the cedars oppressed my lungs.
“We must get out,” Jonas panted, “or at least keep moving.” The splintered end of a branch had gouged his cheek; a trickle of blood coursed down it as he spoke. After looking in both directions he chose the right, toward the river, and lashed his mount to force it into what appeared to be an impenetrable thicket.
I let him break a trail for me, reflecting that if the dark thing caught us I might be able to make some sort of defense against it. Soon I saw it through the gray-green foliage; a few moments later there was another, much like the first and only a short distance behind it.
The wood ended, and we were able to flog our mounts to a gallop again. The fluttering scraps of night came after us, but though their smaller size made them appear swifter, they were slower than the single large entity had been.
“We have to find a fire,” Jonas shouted above the drumming of the destriers’ hooves. “Or a big animal we can kill. If you slashed the belly of one of these beasts, that would probably do it. But if it didn’t, we couldn’t get away.”
I nodded to show that I also opposed killing one of the destriers, though it crossed my mind that my own might soon drop from exhaustion. Jonas was having to allow his to slow now to keep from distancing me. I asked, “Is it blood they want?”
“No. Heat.”
Jonas swung his destrier to the right and slapped its flank with his steel hand. It must have been a good blow, for the animal leaped ahead as though stung. We jumped a dry water course, careened sliding and stumbling down a dusty hillside, then struck open, rolling ground where the destriers could show their best speed.
Behind us fluttered the rags of black. They flew at twice the height of a tall tree and seemed to be blown along by the wind, though the rippling of the grass showed that they faced it.
Ahead, the lay of the ground changed as subtly and yet as abruptly as cloth alters at a seam. A sinuous ribbon of green lay as flat as if it had been rolled, and I swung the black down it, shouting in his ears and belaboring him with the flat of my blade. He was drenched with sweat now and streaked with blood from the broken twigs of the cedars. Behind us I could hear Jonas’s shouted warnings, but I gave them no heed.
We rounded a curve, and through a break in the trees I saw the gleam of the river. Another curve, with the black beginning to flag again—then, far off, the sight
