"'A little knowledge'"—the Captain did not finish the quotation. "Let us turn down here," and not waiting for her consent, he piloted her up a side street. "You do not, then, wish to make a confidant of the police?"

"Non, non, monsieur," lapsing again into rapid French. "I think only of Mademoiselle."

A sudden gleam lighted the Captain's eyes. "Kathleen," his voice lingered on her name. "You think she is in danger?"

"I do, monsieur, in great danger. Did I not see"—she paused in her hasty speech and bit her tongue; one indiscretion was leading to another. "It matters not what I saw, monsieur—I am sometimes nearsighted."

"In that case, your eyes will be examined if testifying in a trial for murder," and he smiled covertly as he saw the fear tugging at her heart-strings. "Enough, Julie; I will respect your confidences. You know—how, I do not inquire—of my deep affection for Mademoiselle Kathleen…."

"Who would not love her?" broke in Julie passionately. "So generous, so fearless and loyal! Ah! she will be faithful to France—she will guard her father's secret—aye, even to the bitter end."

"Hush! not so loud," admonished the Captain, laying a steadying hand on her arm. "Let me think a moment." Totally unconscious of the tears which fell one by one on her white cheeks, the excited Frenchwoman kept step with him in silence for three blocks; then the Captain roused himself. "You are willing to shield Mademoiselle Kathleen at all costs?" he asked.

"Oui, monsieur."

"And you think you can best accomplish that result by avoiding the police?"

"Oui, monsieur."
