"For two pins I'd notify the company what a brute you are, and have a gentleman put here in your place." And with this rebuke he departed. He went to a telegraph office and flashed a message to the authorities of various stations along the line to New York, asking them to hold La Croix if they caught him on the cars. He had to wait an hour for a train to Buffalo, and sent Harry a message telling where he was going. Finally he was carried away in his train. The old detective stopped off at every station to which he telegraphed, but in every instance he received the same answer, that nothing was seen of a man answering La Croix's description. That set the detective thinking. "La Croix was probably keen-witted enough to suspect that we would find his trail and pursue him. In order to conceal his identity he has doubtless disguised himself and thus passed through unrecognized. He has got to dispose of that big lot of diamonds yet. Carrying such a huge amount will of course attract a great deal of attention. Therefore it should be an easy matter to find out where he is operating when he reaches New York." On the following day Old King Brady reached the city. He instituted inquiries about La Croix at once in the jewelry district, but no one seemed to have seen him yet. That did not worry Old King Brady. He was too astute a man to be discouraged by a trifling rebuff. "The villain is keeping shady," was the conclusion he arrived at. "He is going to let the fuss blow over before he exposes his stock. Very foxy, no doubt, but I'm bound to land on him sooner or later." He did not relax his hunt. Nor did he let on to the authorities that he was in town again. He believed in the golden principle of keeping his business to himself until it became absolutely necessary to disclose it. Two days later Harry joined him at their joint lodgings. Young King Brady told how he had tracked Mrs. La Croix and her daughter to swell apartments in the luxurious Waldorf. Here the pair had taken up their abode under the fictitious name of Mrs. Marie P. Savoy and daughter. The Bradys conjectured that it would not take them long to let La Croix know of their whereabouts. They therefore carefully shadowed the big hotel. Nearly a week passed by and one rainy night while Harry was on watch, under an umbrella, across the street from the hotel, he saw a hansom cab dash up to the door, and a man looking like La Croix alighted and hastily made his way into the building on the Thirty-fourth street side. "La Croix, as sure as fate!" the boy muttered, hastily crossing the street. He was heading for the glass portico, when he happened to glance into the spacious dining-room and saw the girl smuggler at supper. Young King Brady paused and watched her. Presently a waiter approached her with a card on a salver. She glanced at it, said something to the man, and while he hastened away, she resumed her supper in a leisurely manner.
