Larry stood in the hallway, undecided. He wanted another opportunity to see and speak to the man he believed was Mah Retto, but he considered it would not be wise to knock again on the door. The occupant of the room either would not answer or would order him away. "I'll have to come again," Larry said to himself. "I've learned one thing, anyhow, and that is where he lives." The young reporter went to the office of the _Leader_ early the next morning. He found Mr. Emberg on hand, and told the city editor the plans for the day; that of making a tour of the steamship piers. Mr. Emberg thought this was a good idea, and complimented Larry on his work thus far. "I ran across my old friend, the East Indian, last night," Larry said, as he was leaving. "I'm going to work him up for a story when I get through with this Potter case." "Don't do it until then," advised Mr. Emberg. "I want you to devote all your attention to the missing millionaire. The East Indian story will not amount to much or I'd put another man on it. You may get a yarn for the Saturday supplement out of it, but even that's doubtful." Larry thought differently, but he did not say so. Nor did he mention that he was going to take Grace Potter with him on his tour of the docks. He had an idea that the city editor might object, or laugh at him, and Larry did not care to have that happen. He felt he was doing right, and he knew there could be no serious objection to the daughter of the missing man aiding in a search for her parent. Larry found Grace waiting for him. She was quietly dressed, and wore a heavy veil, so that no one in the street would recognize her, since her picture had been published in several papers, and there might be comments from the crowd if the daughter of Mr. Potter was seen out in company of a newspaper reporter. "Anything new?" asked the young lady, for she had taken to greeting Larry in that newspaper fashion. "Not much. I didn't learn anything of consequence by my trip to the East Side last night. I'm not done there, however. Now we'll try the piers, and see what sort of a 'pull' you have with the captains of the vessels." "We may not find many captains," Grace said, "unless their ships are about to sail. Still it is worth trying. Shall we start?" "I'm ready any time you are," Larry answered. "What did your mother say?" "She objected a bit at first, but I soon convinced her it was for the best." Larry thought it would not have been hard for Grace to have convinced him that almost anything was for the best. She looked quite trim in her dark dress, with her glossy hair held snugly in place by her veil. As they went down the steps of the mansion Larry saw a man, who was standing on the other side of the street, move rapidly away, as if he had been watching the house. The young reporter uttered an exclamation before he was aware of it, and Grace quickly asked: "What's the matter?" "I--I saw some one," Larry replied.
