"Polly O'Neill," two firm hands next took hold on Polly's thin shoulders, turning her deliberately over in bed so that she was forced to face her questioner, "ever since I can remember there has been some mystery or other connected with this old room. Of course it is not haunted. I suppose sensible people don't believe in ghosts, though I don't see why not believing makes them fail to exist. But the room may have had a tragedy of some kind take place in it, something that both mother and Dick find it painful to mention or recall. I told you that mother would not explain her feeling to me when I insisted upon knowing. However, I don't think my family has the right to keep a secret from me. I am nearly grown now and no longer the kind of girl I used to be. So see here, Polly. Look me directly in the eyes. Oftentimes outsiders hear things first. Have you ever heard of a sorrow or accident, or even something worse, that may have occurred in this house or even in this room when I was too little a girl to understand or remember it? You must tell me the truth."
Polly shook her head, devoutly thankful at the moment for her own lack of information. With Betty's beautiful, honest gray eyes searching her own, with her lips trembling and her cheeks flushed with the fervor of her desire, her friend would have found deceiving her extremely difficult. Yet it was more agreeable to change the subject of their talk, even though it continued upon dangerous grounds.
"No, Betty, I was not thinking of ghosts nor of the fact that you have always been absurdly curious about the mystery of this room. I was thinking of something altogether different—of a thief, in fact—and I was wondering whether you would be angry or hurt or both if I mention something to you?" Polly returned.
Betty kissed her friend's thin cheek, wishing at the same instant that it would grow more rounded, now that Polly was presumably well. "You don't usually mind making me angry, dear," she smiled. "And I don't see why if you have a possible theory of a burglar that I should be hurt. Do you think the figure we saw was a man's or a woman's?"
"I don't know," the other girl replied. "What I have been wondering is just this: Has any one in this house ever come into this room with your mother when she was rummaging in that old closet, to help her move the furniture or lift things about?"
For a moment Betty frowned and then her face flamed crimson.
"You are not fair, Polly. You never have approved of his living here or my being kind to him. And you have said half a dozen times that there was no special point in my being particularly grateful to him, since any one of our friends would have done just what he did, had they been equally near me. But then of course that does not alter the fact. Now just because he has been in here to assist mother does not prove anything, does not even make it fair to be suspicious."
Polly shrugged her shoulders. "I knew you would be angry, so I am sorry I spoke. But you see our first meeting in the woods with the young man when your safety box was almost stolen from you was a little unfortunate. But I don't say that I suspect any one, either, and I have no intention of not being fair. However, I do intend to keep on the lookout. Now kiss me good morning, for I am going to turn out the light. The gray dawn seems at last to be breaking and perhaps we may both get a little sleep before breakfast time."
