"So far so good," he murmured. "Now to go back and see what Grace wanted--that is if it isn't too late."

It was nearly eleven o'clock, but Larry had an idea that Grace would still be up. It was rather an unusual hour to make a call, still all the circ.u.mstances in this case were unusual, and Larry did not think Grace would mind.

He saw a light in the Potter house as he approached it. Thinking perhaps Sullivan might be in the vicinity Larry walked up and down on the other side of the street, peering in the shadow of the tree where he had had his encounter with the politician, but Sullivan had evidently gone away.

"Why didn't you come when I called you?" asked Grace, as she admitted Larry to the library.

"I wanted to," the young reporter replied, "but I had to take after a person who I believe knows where your father is, and I couldn't stop without losing sight of him. I have some news for you."

"And I have some for you," exclaimed Grace, "Let me tell mine first."

"All right," agreed Larry, with a smile. "Go ahead."

"Well, I was sitting in the window to-night, looking out on the street, and feeling particularly sad and lonely on account of father, when I saw a man sneaking along on the other side. I saw him hide behind a tree, and I resolved to keep watch. There have been some burglaries in this neighborhood recently, and I wasn't sure whether he was a thief or a detective sent here to watch for suspicious characters. Well, as I sat there watching I saw you come along and talk to the man behind the tree."

"How long had he been there when I came along?"

"Oh, for some time, but don't interrupt, please. You can ask questions afterward. When I saw you talking to the man I knew it must be all right, and I was beginning to think he was a detective.

"Then I noticed another man sneaking along. He, too, hid behind a tree, next to the first man. I thought this was queer until I remembered you told me that detectives usually hunt in couples, and I thought he was another officer from headquarters. I thought so until mother, who, it seems had been looking out of her window in the front room upstairs, called to me.

"She asked me if I had seen the two men come along, and, when I said I had, she wanted to know if I didn't think there was something queer about the second man. I said I didn't notice particularly, but just then the man stepped out into the light, and I had a good look at him."

"Was there anything suspicious about him?"

"There certainly was!" exclaimed Grace, earnestly. "As soon as I saw him I thought sure it was my father. He had his back toward me, and he looked exactly like papa. Mother saw it, too, and she cried out.

Just then the man turned and I saw he was smooth-shaven, and his face didn't look a bit like my father's.

"Then I saw you and that other man--Mr. Sullivan, I then knew him to be--step into the light. I saw he was going to hit you, and I raised the window and called. I wanted to ask you to see who the second man was--the one who looked so much like my father. I called, but you didn't seem to hear."

"I heard you," replied Larry, "but I couldn't stop. I wanted to take after the man--the same man you were suspicious of. I traced him through the park."

"Did you find him? Who is he? Where is he? Is he--is he? Oh, Larry, don't keep me in suspense----"

"I'm sorry to have to tell you he isn't your father," Larry replied, gently, as he saw the girl's distress. "But I think he knows where your father is. He goes by the name of Mah Retto, and I helped save him from the wreck of a vessel on the Jersey coast. See, I found this in his room, a little while before he disappeared," and he held out to Grace the torn envelope with her name on it.

"My father's writing!" she exclaimed.

Larry heard some one descending the stairs and coming toward the library.

CHAPTER XXIII

CAPTAIN TANTRELLA ARRIVES

"Grace! What is the matter?" exclaimed a woman's voice, and looking up Larry saw Mrs. Potter.

"Nothing, mother," replied the girl. "This is Mr. Larry Dexter. He just brought me some news. Oh, mother, that wasn't papa we saw out in the street!"

"I knew it, dear, as soon as I saw his face."

Larry felt rather uncomfortable, for Mrs. Potter and Grace showed signs of emotion.

"I was telling your daughter," he said to Mrs. Potter, "that I think I have located the man who knows where your husband is."

"Oh, I hope you have," exclaimed Mrs. Potter. "This suspense is awful. Who is he? Where is he?"

Larry related the circ.u.mstances of his chase after Retto, telling how he had located the man at the hotel.

"I'll go and see him to-morrow," he said, "before he has a chance to get away. He does not suspect that I know where he is."

"Why not go now?" asked Mrs. Potter.

"I'm afraid he would see no one to-night. It is very late, and he would suspect something if any one sent up word they wanted to see him. He would at once connect it with the chase I had after him. But I think I fooled him. I am sure he can clear up this matter in a short time, once I get into conversation with him."

"I'll go with you," said Grace, with sudden energy. "I will make him tell where my father is."

Larry thought he could best deal with Retto alone, but he did not want to tell Grace so. However, her mother got him out of what might have been an embarra.s.sing position.

"I'd rather you wouldn't go, Grace," she said. "There is no telling what sort of a person this Retto is. His name sounds foreign."

They talked for some time about the curious circ.u.mstances connected with the disappearance of the millionaire, and when a clock struck the hour of one, Larry arose with a start.

"I had no idea it was so late!" he exclaimed. "I must hurry home, or mother will be worried. I will call to-morrow and let you know what success I have."

"Do, please," said Mrs. Potter.

"And come early," added Grace, as she accompanied Larry to the door.

"Don't let that horrid man stab you with an East Indian poisoned dagger," she went on with a little laugh, as she got out of hearing of her mother.

Larry promised, and then hurried off down the street to the nearest elevated railway station. He was up early the next morning, and wrote out the story of the day's events, including the encounter with Sullivan, and the chase after Retto. He touched as lightly as possible on his own and Grace's parts in the affair, but there was enough to make interesting reading, and he knew no other paper would have it.

"This is good stuff, Larry," complimented Mr. Emberg, when the reporter had turned his story in at the desk. "What next?"

"I'm going to see Retto," was the answer. "I'll make him tell where Mr. Potter is."

"You were right about your East Indian friend," admitted the city editor. "I had no idea there was a story like this connected with him; least of all that it concerned the missing millionaire. Keep right after him. Let us hear from you in time for the first edition.

Whatever you learn from Retto will make the leading part of to-day's account."

"I'll telephone in," said Larry, as he hurried from the city room.

Larry antic.i.p.ated meeting with some difficulty in getting Retto to talk. He knew the man must have a strong motive for aiding Mr.

Potter. Probably the millionaire was paying him well to serve him, to mail letters occasionally, and keep him informed as to how the search for him was progressing.

"There are lots of ends to this that I don't understand," said Larry to himself as he was on his way to the hotel where the mysterious man was stopping. "This mystery seemed to start with the wrecking of the _Olivia_, yet I don't see how I can connect Mr. Potter with that. He must have met Retto in New York after the rescued men came here. Maybe I'm wrong in thinking Mr. Potter is in New York now. He may be some distance off, and depending on Retto to look after his interests. If that's so it would explain why the East Indian was hanging around the house. He wanted to see that Grace and her mother were well, so he could report to the millionaire.
