And suddenly Conan was aware of something unnatural. Zargheba, he knew, was not a tall man. Standing erect, his head would scarcely top the Cimmerian's shoulder; yet that face was on a level with Conan's own. Was the man standing on something? Conan bent and peered toward the ground below the spot where the face showed, but his vision was blocked by undergrowth and the thick boles of the trees. But he saw something else, and he stiffened. Through a slot in the underbrush he glimpsed the stem of the tree under which, apparently, Zargheba was standing. The face was directly in line with that tree. He should have seen below that face, not the tree-trunk, but Zargheba's body--but there was no body there. Suddenly tenser than a tiger who stalks his prey, Conan glided deeper into the thicket, and a moment later drew aside a leafy branch and glared at the face that had not moved. Nor would it ever move again, of its own volition. He looked on Zargheba's severed head, suspended from the branch of the tree by its own long black hair. 3 The Return of the Oracle Conan wheeled supplely, sweeping the shadows with a fiercely questing stare. There was no sign of the murdered man's body; only yonder the tall lush grass was trampled and broken down and the sward was dabbled darkly and wetly. Conan stood scarcely breathing as he strained his ears into the silence. The trees and bushes with their great pallid blossoms stood dark, still and sinister, etched against the deepening dusk. Primitive fears whispered at the back of Conan's mind. Was this the work of the priests of Keshan? If so, where were they? Was it Zargheba, after all, who had struck the gong? Again there rose the memory of Bît-Yakin and his mysterious servants. Bît-Yakin was dead, shriveled to a hulk of wrinkled leather and bound in his hollowed crypt to greet the rising sun for ever. But the servants of Bît-Yakin were unaccounted for. There was no proof they had ever left the valley. Conan thought of the girl, Muriela, alone and unguarded in that great shadowy palace. He wheeled and ran back down the shadowed avenue, and he ran as a suspicious panther runs, poised even in full stride to whirl right or left and strike death blows. The palace loomed through the trees, and he saw something else--the glow of fire reflecting redly from the polished marble. He melted into the bushes that lined the broken street, glided through the dense growth and reached the edge of the open space before the portico. Voices reached him; torches bobbed and their flare shone on glossy ebon shoulders. The priests of Keshan had come. They had not advanced up the wide, overgrown avenue as Zargheba had expected them to do. Obviously there was more than one secret way into the valley of Alkmeenon.
