hair of a native. There’s blood on it, too, for men have been killed trying to steal it, and trying to prevent its being stolen. It’s the most valuable necklace in the world.”
The boy mounted the staircase as he spoke, leading the others to his room, which was at the front of the house on the second floor, directly over the apartment used by his father as a library, or study. The suite occupied by the boy was elegantly furnished, the only thing which marred the tasty arrangement of the place being a steel safe which stood between the two front windows of the sitting room.
“There,” said Frank, closing the door of the room behind the little party, “they got the necklace out of that safe.”
“How did they open it?” asked the lieutenant, and Jimmie laughed.
“Frank never closed a door in his life,” the boy said.
“Was the safe open?” asked Lieutenant Gordon.
“Yes,” was the reply, “it was open. I had just been there to get some money when I heard a scrap going on in the corridor and rushed out, leaving the door open, like a sucker. The necklace was taken while I was gone.”
“Anything else taken?” asked Ned.
“Not a thing. Oh, I guess the thief got a couple of dollars there was in the cash drawer, but nothing else was disturbed.”
“How long was he in the room?” asked the lieutenant.
“Oh, perhaps fifteen minutes. What I mean is that it must have been about that length of time before I came back here. You see, when I got out into the hall, Pedro, that’s one of Dad’s pet servants, was scrapping with two pirate-looking fellows at the head of the stairs. One of them had him by the throat when I came up.”
“And they both got away?” asked the lieutenant.
“Yes, they both got away. They turned and ran down stairs when I came up and bolted out of the front door, just as if some one stood there holding it open for them.”
“Was the night-lock on?”
“Certainly; it always is at night.”
“Couldn’t anybody open it from the inside, whether familiar with the house or not?” asked Ned.
“No; for the night-bolt is controlled by an electric button, which you have to push before it can be moved from the inside, so no one not familiar with the house could have opened it.”
Nestor glanced at the lieutenant with a question in his eyes, and the officer nodded. There was little doubt in the mind of either that the crime had been planned by some one thoroughly conversant with the premises. It was at least certain that exit had been made easy for the thieves.
“You spent this fifteen minutes, after the flight of the thieves by way of the front door, in your father’s room, I take it?” asked Ned.
“Yes; when the thieves ducked out of the front door I found a maid fainting in the corridor running along back of the parlor to Dad’s room, the place where he does his work while in the house. She flopped over when I spoke to her and pointed to Dad’s room. There I found him lying on the couch, drugged with chloroform.”
“They placed him on the couch, did they?”
“Oh, no, sir, the thieves didn’t take that trouble. Pedro was there before I entered the room, and it was he that did that. He had ’phoned for the doctor, too, before I got into the room.”
“He was chasing the thieves?” asked Ned.
“Why, yes. He was just ahead of me at the front door.”
“Then how did he get back and do so much before you reached the study?”
“I opened the front door and looked out for a couple of minutes,” was the reply. “I was rattled, of course, and don’t know how long I stood there, but I remember seeing two men running down the street. If I had known then that they had my emerald necklace, I’d have chased them and roared until the police came up and stopped them.”
“Then you came right in?”
“Yes; right to the corridor where I found the maid lying on the floor.”
“And you remained with your father until the doctor came, and then went back to your room? It was then that you discovered the loss of the emerald necklace?”
“Yes, I missed it when I came back.”
“You saw only two intruders?” asked Ned.
“There were only two.”
“And these two ran down the staircase just ahead of you?”
“Yes; they went down in about one leap.”
“Now, was the necklace in the safe when you went to it?”
“I am certain that it was.”
“You saw it there?”
“I saw the case in which it was enclosed.”
“And the case was gone when you returned?”
“Yes; oh, the necklace was taken from the safe during my absence, all right.”
“Yet the two men were ahead of you, and went out of the street door before you reached the lower landing?”
Frank’s face showed that the idea presented by Nestor was new to him. He had never considered that feature of the case. In fact, he had been so excited that he had not thought logically of the circumstances surrounding the theft.
“Well,” he said, “I reckon I need a hired man to do my thinking for me. Why didn’t that idea get into my thick head before?”
“Are you still certain that the necklace was in the safe when you left the room?” asked Ned, with a smile.
“Yes; I am dead sure of that. Why,” he added, “there must have been a man that I did not see. Wonder why he didn’t give me a clip on the head.”
“Someone will come here an’ steal you, some day,” grinned Jimmie.
“I don’t doubt it,” replied Frank. “Now, where do you think the other man was?” he asked, turning to Ned.
Ned arose and went into the sleeping room, from which opened a bathroom and a large closet. There was a door opening into the sleeping room from the corridor, the apartment being of the same length, east and west, as the sitting room. The closet opened from the sleeping room, and also from the bathroom.
“What do you find here?” asked Frank, following him into the closet and through into the bathroom.
“The third man might have been hiding in here,” Ned replied. “When were you in this bathroom last?” he added, looking carefully about the place.
“Not since early in the afternoon.”
“The suite was unoccupied all the afternoon?”
“Yes; I am rarely here in the afternoon.”
“What
