She quickened her pace. She did not like this promise that she had made; but, on the other hand, she had not made it either lightly or impulsively. She had no regrets on that score. She would make it again under the same conditions. How could she have done otherwise? It would have been to stand aside and permit a crime to be committed which she was assured was easily within her power to prevent. What excuse could she have had for that? Fear wasn't an excuse. She did not like the thought of entering the back door of a store in the middle of the night like a thief, and, like a thief, taking away that hidden money. She knew she was going to be afraid, horribly afraid--it frightened her now--but she could not let that fear make a moral coward of her. Her hands clenched at her sides. She would not allow herself to dwell upon that phase of it! She was going to Skarbolov's, and that was all there was to it. The only thing she really had to fear was that she should lose even a single unnecessary moment in getting there. Halfpast one, Gypsy Nan had said. That should give her ample time; but the quicker she went, the wider the margin of safety. Her thoughts reverted to Gypsy Nan. What had the woman meant by her last few wandering words? They had nothing to do with Skarbolov's, that was certain; but the words came back now insistently. “Seven-three-nine.” What did “seven-three-nine” mean? She shook her head helplessly. Well, what did it matter? She dismissed further consideration of it. She repeated to herself Gypsy Nan's directions for finding the spring of the secret drawer. She forced herself to think of anything that would bar the entry of that fear which stood lurking at the threshold of her mind. From time to time she consulted her watch--and each time hurried the faster. It was five minutes past one when, stealing silently along a black lane, and counting against the skyline the same number of buildings she had previously counted on the street from the corner, she entered an equally black yard, and reached the back door of Skarbolov's little store. She felt out with her hands and found the padlock, and her fingers pressed on the link in the chain that Gypsy Nan had described. It gave readily. She slipped it free, and opened the door. There was faint, almost inaudible, protesting creak from the hinges. She caught her breath quickly. Had anybody heard it? It--it had seemed like a cannon shot. And then her lips curled in sudden self-contempt. Who was there to hear it?
