[Illustration: ""That's a pretty thing to keep hid away!" snarls the now thoroughly angry detective."--page 278.] There may have been times in Alan Warburton's life--such times come to most fastidious city-bred people--when he doubted the wisdom of Providence in permitting the "street musician" to inherit the earth, and, especially to transport so much of his "heritage," wheresoever he might go, upon his person. But to-day, for the first time, he fancies that he sees some reason for the existence of the species, and he finds himself looking down almost complacently upon the crouching minstrel who has lawlessly invaded the sanctity of his splendid cabinet. This strange intruder has brought him at least a respite; and he breathes a sigh of relief even as he asks sternly: "Fellow, how long have you been hiding in that cabinet?" But the culprit is once more a mute; again the pathetic look is in his eyes, and with Grip's hand still clutching his shoulder, he begins a terrified pantomime. "Bah!" says Mr. Grip, pushing his prisoner away contemptuously, "that won't wash. You ain't deaf--not much; nor dumb, neither. Answer me," giving him a rough shake, "how came you here?" There is no sign that the fellow hears or understands; he continues to gesticulate wildly. Mr. Grip releases his hold, and bends upon Alan a look of impatience. In a moment, the organ-grinder bounds to the cabinet and, dragging forth his organ, turns back, displaying it and slinging it across his shoulder with grimaces of triumph. "That won't go down, either," snarls Mr. Grip. "Put that thing on the floor, _presto_!" But the minstrel only grins with delight, and throwing himself into an attitude, begins to grind out a doleful air. With an angry growl, Mr. Grip makes a movement toward him. But the organist retreats as he advances, and the doleful tune goes on. It is a ludicrous picture, and Alan smiles in spite of himself, even while he wishes that Leslie would come now,--now, while he might warn her; now, while Mr. Augustus Grip, in his pursuit of the intruding musician, has put the width of the room between himself and his chosen place of concealment. But Leslie does not come. And Mr. Grip's next remark shows that he has not forgotten himself. With a sudden movement, he wrests the organ from the hands of its manipulator, and converting the strap of the instrument into a very serviceable lasso, brings the fellow down upon his knees with a quick, dexterous throw, and holding him firmly thus, says over his shoulder, to Alan: "This is a fine thing to happen just now! The fellow must be got out of the way, and kept safe until I have time to discover his racket. He's not such a fool as he looks. Can't you get in a policeman quietly? We don't want any servants to gossip over it, or to see me." Alan turns his face toward the closet. "Can't we lock him up again?" he suggests. "My dear sir," says Grip coolly, "this fellow is probably a _spy_."
