"And," added Dillon, "we'd better get started."

He gallantly helped the girl remount her donkey. At the sight, Coburn was shaken out of his numbness. He moved fiercely to intervene. But Janice settled herself in the saddle and Dillon confidently led the way. Coburn grimly walked beside her as she rode. He was convinced that he wouldn't leave her side while Dillon was around. But even as he knew that desperate certitude, he was filled with confusion and a panicky uncertainty.

When they'd traveled about half a mile, another frightening thought occurred to Coburn. Perhaps Dillon—passing for human—wasn't alone. Perhaps there were thousands like him.

Invaders! Usurpers, pretending to be men. Invaders, obviously, from space!

They made eight miles. At least one mile of that, added together, was climbing straight up. Another mile was straight down. The rest was boulder-strewn, twisting, donkey-wide, slanting, slippery stone. But there was no sign of anyone but themselves. The sky remained undisturbed. No planes. They saw no sign of the raiding force from across the border, and they heard no gunfire.

Coburn struggled against the stark impossibility of what he had seen. The most horrifying concept regarding invasion from space is that of creatures who are able to destroy or subjugate humanity. A part of that concept was in Coburn's mind now. Dillon marched on ahead, in every way convincingly human. But he wasn't. And to Coburn, his presence as a non-human invader of Earth made the border-crossing by the Bulgarians seem almost benevolent.

They went on. The next hill was long and steep. Then they were at the hill crest. They looked down into a village called Náousa. It was larger than Ardea, but not much larger. One of the houses burned untended. Figures moved about. There were tanks in sight, and many soldiers in the uniform that looked dark-gray at a distance. The route by which Dillon had traveled had plainly curved into the line-of-march of the Bulgarian raiding force.

But the moving figures were not soldiers. The soldiers were still. They lay down on the grass in irregular, sprawling windrows. The tanks were not in motion. There were two-wheeled carts in sight—reaching back along the invasion-route—and they were just as stationary as the men and the tanks. The horses had toppled in their shafts. They were motionless.

The movement was of civilians—men and women alike. They were Greek villagers, and they moved freely among the unmilitarily recumbent troops, and even from this distance their occupation was clear. They were happily picking the soldiers' pockets. But there was one figure which moved from one prone figure to another much too quickly to be looting. Coburn saw sunlight glitter on something in his hand.
