“Maybe and maybe not. If he and Miss Austin were in collusion—”

“I beg your pardon, Mr. Stone, but I cannot have any thing said in my presence that reflects on that young lady’s good name. We are engaged to be married—that is, I consider myself bound to her, and hope to win her full consent.”

“But I understood—I thought, Trask—”

“Mr. Trask wants to marry her, but I hardly think his suit will succeed. The lady must decide, of course, but I have reason to hope—”

“Gee, Mr. Lockwood, ’course she’ll take you,” Fibsy informed him, “now, let’s you and me get busy to find out Miss Mystery’s mystery. You ought to know it, if you’re going to marry her—and too, you can’t believe there’s anything that can’t stand the light.”

“What can it be?” Lockwood asked, helplessly. “How can a young girl like that have a real secret that so pervades and surrounds her whole life that she will give no hint of it? Who is she? What is she? Why is she here? I don’t believe she came here merely to sketch in water colors.”

“No,” agreed Stone. “If that were all, why the mystery about her home and family? I understand she has given several contradictory statements as to where she really lives.”

“She has,” assented Lockwood. “But may it not be just a twist of her humorous nature? I assure you she is roguishly inclined—”

“No; it isn’t a joke,” Fibsy said, frowning at the thought. “She’s got a real secret, a mystery that means a whole lot to her,—and prob’ly to other people. Well, F. Stone, I guess it’s up to me to go out and seek her people.” He sighed deeply. “I hate to leave the seat of war, but I gotta do it. Nobody else could ever ferret out the antecedents and general family doings of Miss Mystery but Yours Truly. And this is no idle boast. I’m going out for the goods and I’ll fetch home the bacon.”

He looked glum at the prospect, for it looked like no easy or simple matter that he proposed to undertake.
