There had been a time when she had almost loved the life to which John Mark introduced her; there had been a time when she had rejoiced in the nimbleness of her fingers which had enabled her to become an adept as a thief.

And, by so doing, she had kept the life of her brother from danger, she verily believed.

She was still saving him, and, so long as she worked for John Mark, she knew that her brother was safe, yet she hesitated long at the door.
It would be only the work of a moment to flee back to the man she loved, tell him that she could not and dared not stay longer with the master criminal, and beg him to take her West to a clean life.

Her hand fell from the knob, but she raised it again immediately.
It would not do to flee, so long as John Mark had power of life or death over her brother.

If Ronicky Doone, as he promised, was able to inspire her brother with the courage to flee from New York, give up his sporting life and seek refuge in some far-off place, then, indeed, she would go with Bill Gregg to the ends of the earth and mock the cunning fiend who had controlled her life so long.
The important thing now was to disarm him of all suspicion, make him feel that she had only visited Bill Gregg in order to say farewell to him.
