He might betray his enemy, the creature he abhorred, whose downfall would cause him joy.

But his friend?
The very idea was repugnant, impossible to an upright nature.
Juliette's ultimate access of generosity in trying to save him, when she was at last brought face to face with the terrible wrong she had committed, _that_ he put down to one of those noble impulses of which he knew her soul to be fully capable, and even then his own diffidence suggested that she did it more for the sake of his mother or for Anne Mie rather than for him.
Therefore what mattered life to him now?
She was lost to him for ever, whether he succeeded in snatching her from the guillotine or not.

He had but little hope to save her, but he would not owe his life to her.
Anne Mie, seeing him wrapped in his own thoughts, had quietly withdrawn.
Her own good sense told her already that Paul Deroulede's first step would be to try and get his mother out of danger, and out of the country, while there was yet time.
So, without waiting for instructions, she began that same evening to pack up her belongings and those of Madame Deroulede.
There was no longer any hatred in her heart against Juliette.

Where Paul Deroulede had failed to understand, there Anne Mie had already made a guess.

She firmly believed that nothing now could save Juliette from death, and a great feeling of tenderness had crept into her heart, for the woman whom she had looked upon as an enemy and a rival.
She too had learnt in those brief days the great lesson that revenge belongs to God alone..
