While it munched the brittle grass and rolled, he lay at the crest of the low slope, staring eastward. Far away to the northward he could see the road he had left, streaming like a white ribbon over a distant rise. No black dots moved along that glistening ribbon. There was no sign about the castle in the distance to indicate that the keepers had noticed the lone wayfarer. An hour later the land still stretched bare. The only sign of life was a glint of steel on the far-off battlements, a raven in the sky that wheeled backward and forth, dipping and rising as if seeking something. Conan saddled and rode westward at a more leisurely gait. As he topped the farther crest of the slope, a raucous screaming burst out over his head, and looking up, he saw the raven flapping high above him, cawing incessantly. As he rode on, it followed him, maintaining its position and making the morning hideous with its strident cries, heedless of his efforts to drive it away. This kept up for hours, until Conan's teeth were on edge, and he felt that he would give half his kingdom to be allowed to wring that black neck. 'Devils of hell!' he roared in futile rage, shaking his mailed fist at the frantic bird. 'Why do you harry me with your squawking? Begone, you black spawn of perdition, and peck for wheat in the farmer's fields!' He was ascending the first pitch of the hills, and he seemed to hear an echo of the bird's clamor far behind him. Turning in his saddle, he presently made out another black dot hanging in the blue. Beyond that again he caught the glint of the afternoon sun on steel. That could mean only one thing: armed men. And they were not riding along the beaten road, which was out of his sight beyond the horizon. They were following him. His face grew grim and he shivered slightly as he stared at the raven that wheeled high above him. 'So it is more than the whim of a brainless beast?' he muttered. 'Those riders cannot see you, spawn of hell; but the other bird can see you, and they can see him. You follow me, he follows you, and they follow him. Are you only a craftily trained feathered creature, or some devil in the form of a bird? Did Xaltotun set you on my trail? Are you Xaltotun?' Only a strident screech answered him, a screech vibrating with harsh mockery. Conan wasted no more breath on his dusky betrayer. Grimly he settled to the long grind of the hills. He dared not push the horse too hard; the rest he had allowed it had not been enough to freshen it. He was still far ahead of his pursuers, but they would cut down that lead steadily. It was almost a certainty that their horses were fresher than his, for they had undoubtedly changed mounts at that castle he had passed.
