If Guillaume had trembled it was simply with fear that his invention might be divulged in consequence of Salvat's crime.

The slightest indiscretion might compromise everything; and that little stolen cartridge, whose effects had so astonished _savants_, might reveal his secret.

He felt it necessary to act in mystery, choosing his own time, awaiting the proper hour, until when the secret would slumber in its hiding-place, confided to the sole care of Mere-Grand, who had her orders and knew what she was to do should he, in any sudden accident, disappear.
"And, now," said Guillaume in conclusion, "you know my hopes and my anguish, and you can help me and even take my place if I am unable to reach the end of my task.

Ah! to reach the end! Since I have been shut up here, reflecting, consumed by anxiety and impatience, there have been hours when I have ceased to see my way clearly! There is that Salvat, that wretched fellow for whose crime we are all of us responsible, and who is now being hunted down like a wild beast! There is also that insensate and insatiable _bourgeoisie_, which will let itself be crushed by the fall of the shaky old house, rather than allow the least repair to it! And there is further that avaricious, that abominable Parisian press, so harsh towards the weak and little, so fond of insulting those who have none to defend them, so eager to coin money out of public misfortune, and ready to spread insanity on all sides, simply to increase its sales! Where, therefore, shall one find truth and justice, the hand endowed with logic and health that ought to be armed with the thunderbolt?
Would Paris the conqueror, Paris the master of the nations, prove the justiciar, the saviour that men await! Ah! the anguish of believing oneself to be the master of the world's destinies, and to have to choose and decide." He had risen again quivering, full of anger and fear that human wretchedness and baseness might prevent the realisation of his dream.

And amidst the heavy silence which fell in the room, the little house suddenly resounded with a regular, continuous footfall.
"Ah, yes! to save men and love them, and wish them all to be equal and free," murmured Pierre, bitterly.
