All Alice could do was to ask her address, which she gave, and to tell her to call next day. It was a certain street and number in Brooklyn. As for Ed, she never mentioned his name. "She's a bad one," observed Harry after she had gone. "I take no stock in that woman." Alice took none either. "I am going around to Mrs. Fang's to see if she has any word for me," she said, referring to the wife of the Chinese detective. "I'll see you at the office if there is anything to report." But there was nothing, and that day closed, leaving the case involved in mystery. Next day Old King Brady had Alice write a Chinese advertisement offering $200 reward for any information which would lead to the discovery of Ed Butler's whereabouts. This Harry posted on the dead wall at the corner of Pell and Doyer streets, where hundreds of little red slips can be seen any day. This wall is called the Chinese bulletin board, also the Chinese newspaper. Old King Brady offered the reward on his own account, but the address given was Alice's, on Pell street, and a Chinese name was signed. Knowing that if anything was to come of it, early evening would be the probable time. The Bradys were on hand at the room right after supper. At about half-past seven o'clock there came a knock on the door. Old King Brady and Harry slipped into the other room, leaving Alice to open the door. An aged Chinaman stood outside. Alice asked him his business in his own language. The answer was rather a surprise, for it came in pigeon English: "Me wantee see Kling Blady." "Old King Brady is not here," replied Alice. "What makes you think that?" "Oh, me know. He camee here. Me see. Me know you, too." Seeing that the case was hopeless, Alice asked him inside. The old fellow shuffled into the room and looked around cautiously. "Come," said Alice, "tell me what you want." "Bout boy?" was the reply. "No telle you. Only tellee Kling Blady." The old detective walked into the room. He did not know the man so far as he could remember. Nor was he particularly surprised at the situation, for he had taken no steps to conceal his identity. "Hello, John! Here I am. Now what you got to say to me about that boy?" he asked. "Money," replied the Chink. "Me can tell. Two hlundled dlollar--yair." "You are up against it, governor," laughed Harry. "Do you propose to pay in advance for your Chinese clew?" Old King Brady's answer was a roll of bills. "I should have looked out for the boy better," he said. "I am willing to pay for my carelessness." "See, John," he added, holding up ten ten-dollar bills, which he spread out like a fan. "Half now; other half when we get the boy." The old man eyed the bills longingly, but shook his head. "No tellee," he said. "You givee two hlundled dollars, den me tell." "Get out," said Old King Brady, pocketing the bills. "You're a fraud. You don't know anything about the boy." CHAPTER IV. SUNKEN TREASURE.
