The girl's eyes narrowed and Foster knew she was afraid, but did not think fear was her strongest emotion.
"You mean he may try again?"
"That is what I mean. If he comes back, you must watch him, but keep him here until I arrive. If it's impossible for me to come, send for the police."
"Yes," said Lucy quietly, "I'll try."
"There's another risk," said Foster. "He may send an accomplice; they're a well-organized gang. In this matter, I'd sooner trust you than Lawrence." He stopped for a moment and gave her an apologetic glance. "Perhaps I've done wrong to alarm and put this heavy load on you."
"No," she said resolutely. "I have promised to marry Lawrence and must help him."
Then she rose and gave Foster her hand. "I must thank you for your confidence. If the need comes, I don't think I'll fail you."
Foster felt satisfied when she left him. Lucy was clever and had pluck. He had given her a hard part, but she would not shrink. One could trust a woman who was fighting for her lover.
After breakfast next morning, Mrs. Stephen showed Foster some photographs of the mountains, in one or two of which Lucy and Lawrence had a place, and he asked: "Have you a portrait of Walters?"
"No; the man who took these was staying here, and one day asked Walters to join the group he was posing, but he refused."
