On the farther side of the rows of sphinxes too, which he had now reached, there was not a man to be seen--not a watchman even though the white limestone of the tombstones and the yellow desert-sand shone as clear in the moonlight as if they had some internal light of their own. At every instant he grew more and more uneasy, he climbed to the top of a sand-hill to obtain a wider view, and loudly called Klea's name. There--was he deceived? No--there was a figure visible near one of the ancient tomb-shrines--a form that seemed wrapped in a long robe, and when once more he raised his voice in a loud call it came nearer to him and to the row of sphinxes. In greate haste and as fast as he could he got down again to the roadway, hurried across the smooth pavement, on both sides of which the long perspective of man-headed lions kept guard, and painfully clambered up a sand-heap on the opposite side. This was in truth a painful effort, for the sand crumbled away again and again under his feet, slipping down hill and carrying him with it, thus compelling him to find a new hold with hand and foot. At last he was standing on the outer border of the sphinx-avenue and opposite the very shrine where he fancied he had seen her whom he sought; but during his clamber it had become perfectly dark again, for a heavy cloud had once more veiled the moon. He put both hands to his mouth, and shouted as loud as he could, "Klea!"--and then again, "Klea!" Then, close at his feet he heard a rustle in the sand, and saw a figure moving before him as though it had risen out of the ground. This could not be Klea, it was a man--still, perhaps, he might have seen his darling--but before he had time to address him he felt the shock of a heavy blow that fell with tremendous force on his back between his shoulders. The assassin's sand-bag had missed the exact spot on the nape of the neck, and Serapion's strongly-knit backbone would have been able to resist even a stronger blow. The conviction that he was attacked by robbers flashed on his consciousness as immediately as the sense of pain, and with it the certainty that he was a lost man if he did not defend himself stoutly. Behind him he heard another rustle in the sand. As quickly as he could he turned round with an exclamation of "Accursed brood of vipers!" and with his heavy staff he fell upon the figure before him like a smith beating cold iron, for his eye, now more accustomed to the darkness, plainly saw it to be a man. Serapion must have hit straight, for his foe fell at his feet with a hideous roar, rolled over and over in the sand, groaning and panting, and then with one shrill shriek lay silent and motionless.
