"Mr. Talbot keeps his finest pieces in a cabinet built into the bookshelves in his library. It's on the left side as you stand in the drawing-room door, and you look for the works of Thomas Carlyle. There's a dozen or so volumes of Carlyle, only they're not books,—not really,—but just the backs of books painted on the steel of a safe. And if you press a spring in the upper right-hand corner of the shelf just over these books the whole section swings out. I suppose you've seen that sort of hiding-place for valuables?"

"Well, not exactly, miss. But havin' a tip helps, an' ef there ain't no soup to pour—"

"Soup?" inquired Muriel, wrinkling her pretty brows.

"That's the juice we pour into the cracks of a safe to blow out the lid with," The Hopper elucidated. "Ut's a lot handier ef you've got the combination. Ut usually ain't jes' layin' around."

"I should hope not!" exclaimed Muriel.

She took a sheet of paper from the leathern stationery rack and fell to scribbling, while he furtively eyed the window and again put from him the thought of flight.

"It's half-past eleven and you can catch a trolley in ten minutes that will take you right past papa's house.

He stood watching her nimble fingers, fascinated by the boldness of her plan for restoring amity between Shaver's grandfathers, and filled with admiration for her resourcefulness.

He asked a few questions as to exits and entrances and fixed in his mind a very accurate picture of the home of her father. She then proceeded to enlighten him as to the ways and means of entering the home of her father-in-law, which she sketched with equal facility.

"There's a French window—a narrow glass door—on the veranda. I think you might get in there!" She made a jab with the pencil. "Of course I should hate awfully to have you get caught! But you must have had a lot of experience, and with all the help I'm giving you—!"
