"Fortunately!" cried Gerald; "fortunately! Why? What right has such a man to live? He must have killed him!" Virdow read on. A cry broke from Gerald's lips as the explanation appeared. "I was right! The hand becomes a part of the eye when the mind wills it; or, rather, eye and hand become mind. The will is everything. But why he should have struck the guard----" He went to the wall and took down two pistols. Handing one to Virdow and stepping back he said: "You will please sight at my face a moment; I cannot understand how the accident could have happened." Virdow held the weapon gingerly. "But, Herr Gerald, it may be loaded." "They are empty," said Gerald, breeching his own and exposing the cylinder chambers, with the light shining through. "Now aim!" Virdow obeyed; the two men stood at ten paces, aiming at each other's faces. "Your hand," said the young man, "covers your mouth. Edward aimed for the mouth." There was a quick, sharp explosion; Virdow staggered back, dropping his smoking pistol. Gerald turned his head in mild surprise and looked upon a hole in the plastering behind. "I have no recollection of loading that pistol," he said. And then: "If your mind had been concentrated upon your aim I would have lost a finger and had my weapon driven into my face." Virdow was shocked at the narrow escape and pale as death. "It is nothing," said Gerald, replacing the weapon; "you would not hit me in a dozen trials, shooting as you do." At 10 o'clock that night Edward, pale and weary, entered. He returned with emotion the professor's enthusiastic embrace, and thanked him for his care and attention of Gerald and the household and for his services to the dead. Gerald studied him keenly as he spoke, and once went to one side and looked upon him with new and curious interest. The professor saw that he was examining the profile of the speaker by the aid of the powerful lamp on the table beyond. The discovery set his mind to working in the same direction, and soon he saw the profiles of both. Edward's did not closely resemble the other. That this was true, for some reason, the expression that had settled upon Gerald's face attested. The portrait had been covered and removed. Edward, after concluding some domestic arrangements, went directly to his room and, dressed as he was, threw himself upon his bed and slept.
