His eyes, however, were full of tears, his ears sung, and his head buzzed, partly from the blow on the jaw, partly from the force with which he had come in contact with the ground. Edward lightly sprung aside and avoided the cut aimed at him, and then delivered a blow with all his force just in front of the ear, and the man dropped again as if shot. In a moment Edgar had wrenched the knife from his hand, then he turned to the young Arab.
