"They gave him an overdose. He was almost gone. He must not be moved out of here under two days. I shall want to see him twice again." "The case is yours," said Old King Brady. "I shall stay right here with him." But he did not. Harry here spoke again. "Governor," he said, "you want to get right up to that pier. Never mind me. I dreamed that I saw you there and that you got--you know what. Go now." And Harry was so earnest about it that Old King Brady went, leaving him in charge of Alice and Quong Lee. It was well towards midnight before Old King Brady again found himself approaching the old fertilizer factory. He was not alone. Feeling that he might need help he confided the details of his case to Wardman Connors and took him along. "I don't see a soul," remarked Connors as they approached the pier. "I am afraid it is all Harry's imagination." They started down the pier and had gone but a short distance before they made a discovery. It was a Chinaman lying gagged and bound upon the pier. "Why, I know this Chink!" exclaimed Connors. "He is a notorious Pell street highbinder. Name is Tom Quee." The imprisoned Chinaman was regarding him with a disgusted stare. They set him free at once and Connors started to question him. "Know Dock Hing?" said Tom Quee. "Well, he did it. He's hanging around here somewhere in a boat along with another fellow." "Why?" demanded Old King Brady. "I don't know," retorted Tom Quee. "We had a quarrel--that's all." They started across the pier thinking that Tom Quee would follow them. Suddenly they heard the patter of feet and looking back saw the Chinaman on the run. They went on the stringpiece then, making as little noise as possible. Looking down they saw a boat at some distance ahead in which sat two Chinamen. They were looking down into the water. "Sure enough they are the men now!" muttered Old King Brady. "Connors, these are the ones we want. Upon my soul I believe that boy is diving for them now." He was right. At the same moment up came Ed out of the water. He was empty-handed. One of the Chinamen seized an oar and would have struck at him but Old King Brady raised a shout. The Chinamen looking up and seeing the detectives, instantly pulled their boat in under the pier. "That you, Ed Butler?" cried Old King Brady, hurrying forward. "Oh, Mr. Brady! I'm so thankful you have come!" Ed cried. "I've had such a time of it since I parted with you." "There go the Chinks!" exclaimed Connors, pointing to the boat which was pulling away from the pier. "I found two metal cases down there. One last night those Chinamen opened. There was nothing in it but a lot of papers," said Ed. "And the other?" "That I got to-night, and oh, Mr. Brady, I have had the time of my life to keep it out of the hands of those Chinamen." "But where is it now?" demanded the old detective impatiently. "I tied it to the lowest rung of that ladder under the water," said Ed.
