Kitty Killigrew, alone in a cab in a London fog, hears the voices of two men outside. A scrap or two of their conversation catches her interest, then they are gone. A few moments after the door opens, and a man enters the cab, evidently mistaking it for his own. Learning of his mistake, he apologizes and disappears— taking with him Miss Kllligrew's sapphire necklace. Miss Killigrew has a good memory for voices. Later in America she recognizes the voice of the man who stood outside her cab; also the voice of the man who entered it. The first voice belongs to Thomas Webb, her mother's secretary; the second to Lord Monckton, a suitor for her hand. But the sapphires are in the possession of Thomas Webb. All of which makes a pretty tangle out of which a pleasant love story develops.

Altogether, a rather intricate tangle, as tantalizing as one of those scroll-saw puzzles; and yet, under MacGrath's deft manipulation, each enigmatic piece slips neatly and accurately into place until the finished pattern lies before us. There is just one detail which somewhat cheapens the quality of the story as regards technique.
