“What can we do for you, stranger?” asked Dr. Bell of the silent figure in the door. “Stranger!” exclaimed the hollow, metallic voice that issued from somewhere beneath the visor of the cap. “I am no stranger, though possibly you do not recognize me. Do you remember your rival George Gregory, Dr. David Bell? I am he.” “You—it is impossible,” exclaimed the amazed doctor. “Gregory was a tall man, altogether different in appearance. You—” “Nevertheless I tell you I am George Gregory and I have come to settle old accounts with you. Clear out,” he shouted to the frightened Stevens. “My trouble is not with you.” Lucius lost no time in following the stranger’s suggestion. After his departure the two men in the operating room faced each other for some moments in silence. “Before I have done with you,” came the metallic tones again, “I will explain a few things that may puzzle you.” Here he walked to the office door, locked it and put the key into the overcoat pocket. “Now, sit down, David Bell, don’t be in a hurry, for you are not going to leave this room alive. I promise you that, and I am accustomed to doing what I promise.” Bell did as he was bade. The curiosity of his analytical mind was aroused and he wished to find out more about this stranger whose identity he could in no way associate with Gregory. Fascinated, he watched while the man removed his cap and overcoat, and then before David’s startled gaze the newcomer placed his right hand to his left shoulder and with a slight manipulation removed the left arm which he propped up in the chair nearest him. He then seated himself and proceeded to dismember himself until nought but a torso, head and one arm remained, all of which were scarred with countless incisions. A mirthless laugh jarred to the depths the doctor’s overwrought nerves. The features of the intruder were not recognizable as those of his former friend, Gregory. There was no nose, only two nostrils flat upon the surface of the face. The head was bald and earless, the mouth a toothless gap. A shudder of disgust went through David, and again the dry laugh of this monstrosity echoed through the room.
