Feeling before him with hands and feet he made the circuit of the room before he reached the bed. Scarce breathing he leaned over and groped across the covers with his fingers in search of his prey—the bed was empty. With the discovery came a sudden nervous reaction that sent him into a cold sweat. Weakly, he seated himself upon the edge of the bed. Had his fingers found the throat of Professor Maxon beneath the coverlet they would never have released their hold until life had forever left the body of the scientist, but now that the highest tide of the young man’s hatred had come and gone he found himself for the first time assailed by doubts. Suddenly he recalled the fact that the man whose life he sought was the father of the beautiful creature he adored. Perhaps she loved him and would be unhappy were he taken away from her. Number Thirteen did not know, of course, but the idea obtruded itself, and had sufficient weight to cause him to remain seated upon the edge of the bed meditating upon the act he contemplated. He had by no means given up the idea of killing Professor Maxon, but now there were doubts and obstacles which had not been manifest before. His standards of right and wrong were but half formed, from the brief attempts of Professor Maxon and von Horn to inculcate proper moral perceptions in a mind entirely devoid of hereditary inclinations toward either good or bad, but he realized one thing most perfectly—that to be a soulless thing was to be damned in the estimation of Virginia Maxon, and it now occurred to him that to kill her father would be the act of a soulless being. It was this thought more than another that caused him to pause in the pursuit of his revenge, since he knew that the act he contemplated would brand him the very thing he was, yet wished not to be. At length, however, he slowly comprehended that no act of his would change the hideous fact of his origin; that nothing would make him acceptable in her eyes, and with a shake of his head he arose and stepped toward the living room to continue his search for the professor. In the workshop Bududreen and his men had easily located the chest. Dragging it into the north campong the Malay was about to congratulate himself upon the ease with which the theft had been accomplished when one of his fellows declared his intention of going to the house for the purpose of dispatching Professor Maxon, lest the influence of his evil eye should overtake them with some terrible curse when the loss of the chest should be discovered.
