and rapidly sketched the outline of one of the two faces--that of a bland-looking young man, with no expression worth mentioning. "There's the Colonel in his simple disguise. Very good. Now watch me: figure to yourself that he adds here a tiny patch of wax to his nose--an aquiline bridge--just so; well, you have him right there; and the chin, ah, one touch: now, for hair, a wig: for complexion, nothing easier: that's the profile of your rascal, isn't it?"

That is already much--to unravel Colonel Clay, gentlemen!" "Well, what do you make of it?" Sir Charles asked, crestfallen. The Commissary sat down and gloated over his discovery. It was
