"Why! In order that I may be believed!" cried Guillaume with extraordinary force of utterance. Then he added, "The edifice must lie on the ground, and I must be under it. If the experiment is not made, if universal horror does not attest and proclaim the amazing destructive power of my explosive, people will consider me a mere schemer, a visionary! . . . A lot of dead, a lot of blood, that is what is needed in order that blood may for ever cease to flow!" Then, with a broad sweep of his arm, he again declared that his action was necessary. "Besides," he said, "Salvat left me the legacy of carrying out this deed of justice. If I have given it greater scope and significance, utilising it as a means of hastening the end of war, this is because I happen to be a man of intellect. It would have been better possibly if my mind had been a simple one, and if I had merely acted like some volcano which changes the soil, leaving life the task of renewing humanity." Much of the candle had now burnt away, and Guillaume at last rose from the block of stone. He had again consulted his watch, and found that he had ten minutes left him. The little current of air created by his gestures made the light flicker, while all around him the darkness seemed to grow denser. And near at hand ever lay the threatening open mine which a spark might at any moment fire. "It is nearly time," said Guillaume. "Come, brother, kiss me and go away. You know how much I love you, what ardent affection for you has been awakened in my old heart. So love me in like fashion, and find love enough to let me die as I want to die, in carrying out my duty. Kiss me, kiss me, and go away without turning your head." His deep affection for Pierre made his voice tremble, but he struggled on, forced back his tears, and ended by conquering himself. It was as if he were no longer of the world, no longer one of mankind. "No, brother, you have not convinced me," said Pierre, who on his side did not seek to hide his tears, "and it is precisely because I love you as you love me, with my whole being, my whole soul, that I cannot go away. It is impossible! You cannot be the madman, the murderer you would try to be." "Why not? Am I not free. I have rid my life of all responsibilities, all ties. . . . I have brought up my sons, they have no further need of me. But one heart-link remained--Marie, and I have given her to you." At this a disturbing argument occurred to Pierre, and he passionately availed himself of it. "So you want to die because you have given me Marie," said he. "You still love her, confess it!" "No!" cried Guillaume, "I no longer love her, I swear it. I gave her to you. I love her no more." "So you fancied; but you can see now that you still love her, for here you are, quite upset; whereas none of the terrifying things of which we spoke just now could even move you. . . . Yes, if you wish to die it is because you have lost Marie!"
