"It's an insult," Loreen protested. "All these talks and visits are insults. To be sure, this detective has some excuse, but——"

"Keep your eye on Lucetta," I interrupted. "She is shaking her head and looking very positive. She will prove to him it is an insult. We need not interfere, I think."

But Loreen had grown pensive and did not heed my suggestion. A look that was almost wistful had supplanted the expression of indignant revolt with which she had addressed me, and when next moment the two we had been watching turned and came slowly toward us, it was with decided energy she bounded forward and joined them.

"What is the matter now?" she asked. "What does Mr. Gryce want, Lucetta?"

Mr. Gryce himself spoke.

"I simply want her," said he, "to assist me with a clue from her inmost thoughts. When I was in your house," he explained with a praiseworthy consideration for me and my relations to these girls for which I cannot be too grateful, "I saw in this young lady something which convinced me that, as a dweller in this lane, she was not without her suspicions as to the secret cause of the fatal mysteries which I have been sent here to clear up. To-day I have frankly accused her of this, and asked her to confide in me. But she refuses to do so, Miss Loreen. Yet her face shows even at this moment that my old eyes were not at fault in my reading of her. She does suspect somebody, and it is not Mother Jane."

"How can you say that?" began Lucetta, but the eyes which Loreen that moment turned upon her seemed to trouble her, for she did not attempt to say any more—only looked equally obstinate and distressed.

"If Lucetta suspects any one," Loreen now steadily remarked, "then I think she ought to tell you who it is."

"You do. Then perhaps you—" commenced Mr. Gryce—"can persuade her as to her duty," he finished, as he saw her head rise in protest of what he evidently had intended to demand.

"Lucetta will not yield to persuasion," was her quiet reply. "Nothing short of conviction will move the sweetest-natured but the most determined of all my mother's children. What she thinks is right, she will do. I will not attempt to influence her."
