Such boxes and opium bales as were piled on the larger box were transferred to the launch, and a rope made fast around the box, which was then hauled up, but not without considerable difficulty, and carried in front of the first warehouse of the row, where it was placed on the board platform. Alice now called again to the imprisoned princess, but received no answer. "I'll be blest if I see how we are ever going to get this thing open without a screw-driver," grumbled one of the Secret Service men. "I can supply that want," replied the old detective, who usually has a few tools concealed in some of the many pockets of that wonderful blue coat. He hastily produced it and went to work. The screw-driver was not only a small affair, but the blade folded into a slot in the handle. The joint being loose, it made the tool wobbly. Old King Brady soon discovered that he had attempted the impossible. He could not start a single screw. "This is a bad job," he exclaimed. "We shall have to lower the box again. I greatly fear that we are up against a murder case. If the woman was alive, she would surely have revived before this." "She said she was dying," replied Alice. "It begins to look as if she spoke the truth." "Get back to the boat," called Harry. "We may as well run around to the India Basin warehouse. We shall be able to open the box there." "I see no other way," replied Old King Brady, and once again he started to make fast the rope, when suddenly Harry called that he could hear the sound of oars. "Which way?" demanded the old detective. "Up the channel. Don't seem to be far off, either." "Come, boys," said Old King Brady, "we'll sneak along the bulkhead and see who it is. Crouch low, now. If it is the Chinamen prowling about, we may be able to bag them. Alice, you better go aboard the launch." "I'll stay here and watch the box," replied Alice. The old detective and the two Secret Service men now crept along the line of the bulkhead with their revolvers drawn. Alice quickly lost sight of them in the fog, which was now thicker than ever. "Alice, are you all right up there?" called Harry. "Of course," she replied. "Why not?" "I wish you would come down." "And abandon my imprisoned princess? I won't." Harry and Alice are lovers, and practically engaged. Long ago they would have been married if Alice would only consent to give up her work. But Alice is perfectly fascinated with the life of a detective, so the marriage day is forever being postponed, for Harry insists that Alice shall give up the business before becoming his wife. But even under their present relations he sometimes tries to force her to yield to his ideas more than she cares for, although he has long ago learned that she is a difficult person to drive. Harry knew by her tone now that Alice had made up her mind to stay just where she was, so he let the matter drop and was sitting in the launch in silence when suddenly a shot rang out.
