"This is a simple-minded youth," grinned Lilienthal, as he turned away. "He has swallowed my story, and--I fancy I see Mr. Fritz Braun's little game. I wonder if the Vienna witch is still over there. I must hurry up and post her. This young chap may be a good customer, for he handles plenty of money." And the brisk Figaro darted away, his eyes gleaming in the ardor of the undying covetousness of the Israelite. While Mr. Adolph Lilienthal was cautiously conducting a Philadelphia money magnate into the "Private Gallery," a closely veiled lady was entering that sanctum from the photographer's hall. The secret of the two double rings of the push button admitted her to the "packing room," where an innocent-faced young German lad stood guard over the complicated system of letter boxes, telegraph racks, and telephones in that jealously guarded "packing room." It had been a busy morning with the astute Lilienthal, and the sudden arrival of the "big fish," a wary "customer" from the Schuylkill, caused the dealer to temporarily forget Randall Clayton. He scented only an ordinary amorous intrigue in the young man's ardent desire to make that particular "artist proof" his own. Besides, the postman had just staggered in with a considerable bundle of letters all addressed to the Newport Art Gallery. There was a good hour's work for the rosy-faced graduate of a Viennan cafe in removing the decoy wrappers and assorting the private correspondence which alone paid the rental of Mr. Lilienthal's "emporium." Randall Clayton was already hastening back from the Astor Place Bank, forgetting his own luncheon in his eagerness to hear once more of Fraeulein Irma Gluyas, when Mr. Fritz Braun had at last disposed of the morning swarm of "privately attended" customers at Magdal's Pharmacy. The blue-spectacled chemist had been working with lightning rapidity behind his effective screen, following the whispered directions of his depraved London assistant. It was for him an anxious morning. His heart would have leaped up in a wild joy had he known how carefully Randall Clayton had already entered the accidentally found address in the little silver-clasped address book, in which he had recorded, with judicious cabalistic cloudiness, the combinations of his safes and certain vital private business memoranda. These secrets were all hidden in a mass of artfully inserted characters so as to defy the curious eye of any stranger in case of mishap, but the young cashier's fingers trembled with eagerness as he had paused on his way in a corridor to boldly enter an already beloved name. "I can easily find her out over there," Clayton murmured. "She shall not drift out of my life. I must some day read the secret of those wistful eyes."
