The girls tried to guess from the shelf where she had stood what book she had been consulting, but as it was a long row of encyclopedias, all exactly alike, they could not glean the least inkling. Giving up that course, they questioned the librarian on the way out, and found that the Imp had joined the library several days before. "Did you ever know anything to beat it?" demanded Sue, as they passed down the steps. "What can she be up to? I know she's awfully bright and reads lots of books that interest grown-folks, but she's so lazy about things and so crazy just to be outdoors that she never thought it worth while to join the library before." "She said," Carol reminded her, "that her teacher, Miss Hastings, advised her to look up something. You know she always tells the truth, at least." "That's true," admitted Sue, "but it must be something out of the ordinary, or she would simply have come to us and bribed us to go and do it for her. And besides, in her class they don't have to look up things in encyclopedias; they haven't got to that yet. No, I'm certain it's something else." Wondering about the Imp's strange behavior, they harked back, as they walked homeward, to that other subject that was constantly puzzling them. "Do you know," said Carol, "I believe that I've come to agree with you in your theory about Louis and Monsieur. You know I didn't when you first told me, because I was awfully disappointed about his not being a count or a duke. But now I think that you're right. Monsieur is probably the family lawyer, and Louis is going to inherit a big French fortune. But if that is the case, why is it that Monsieur seems to be trying so hard to make Louis like him? You remember, Louis said the other day that he constantly feels as if Monsieur were doing everything in his power to win his affection, for some reason or other. If he were only a family lawyer, he wouldn't care a penny whether Louis liked him or not. And why was he kissing his hand the other day? I'm half-inclined to believe that he's some relative--a grandfather or an uncle or something. Yet he could scarcely be that, and the lawyer, too. Isn't it a puzzle?" "But don't you remember that Miss Yvonne told Louis he wasn't any relative?" Sue reminded her; "only an old friend of the family." "Susette," remarked Carol solemnly, stopping stock still in the middle of the road, "you may call me all kinds of an idiot if you like, but I want to tell you one thing.
