ne side of the box, his keen eye had discovered a paper, yellow and
musty with age, the sight of which thrilled him with hope. He
quickly drew it forth, and a single glance at its title assured him
it was indeed the object of his search. With a low cry of joy, he
locked and replaced the metallic box, and, opening the ancient
document, he eagerly scanned its contents, an expression of intense
satisfaction overspreading his features.

He was still perusing the paper when he heard footsteps approaching
the library through the long corridor, followed an instant later by a
knock. Depositing the precious document safely within an inside

see Mr. Mainwaring? I called at his city office and was directed
here; but the butler states that Mr. Mainwaring is away from home, and
is unable to say when he will return, or how soon he would be at

"Mr. Mainwaring will probably return about five o'clock; but it is
rather difficult for me to state when you could see him, as he is
entertaining a number of guests, and it is doubtful if he would care
