the Greistman jewels, reported by means of the organization, no doubt. The note had been written on a typewriter, and there were no marks on the envelope. Any active crook might have been able to discover where the members of the Greistman family slept, and learn where the safe was kept, and how the doors and windows of the library were located, but only some one in close touch with the family could know when they anticipated taking the jewels from the safe-deposit box and where they would be kept the night after the ball.
Verbeck found himself wondering how this information had been obtained and whether the man who now stood before him in robe and mask had obtained it or was merely a messenger to carry it to the Black Star. He stepped back to the blackboard and picked up the chalk again.
“Where did you get information?” he wrote.
“As you instructed,” came the written answer.
Verbeck could ask no more without betraying himself. He had no idea regarding the identity of the man before him. It was possible, of course, for him to call Muggs from the other room and overpower the crook, but it was doubtful if the man would talk and reveal anything after he discovered he was not dealing with the Black Star, but with an outsider. And what Verbeck wanted was accurate knowledge; he would have to be careful not to arouse the man’s suspicion.
“Good!” he wrote on the blackboard. Then he nodded to the man, as if in dismissal. But the other did not seem ready to go, and acted as if there was something wanting.
“Any orders?” he wrote finally.
Verbeck remembered the pile of letters on the end of the table, and now he went over and inspected them. They were orders for members of the band, evidently, for on each envelope a number was stamped. He found the one marked “Eight,” and took out the sheet of paper it contained. There were the orders the Black Star had prepared for this man:
At three o’clock in the afternoon there is a committee meeting of the Browning Club in a parlor of the second floor of the National Hotel, at which Miss Freda Brakeland will be present. Manage to be in the lobby of the hotel after the meeting, and meet Miss Brakeland as if by accident. Talk of the Charity Ball, and ascertain whether she is to wear the famous Brakeland jewels at that affair. Report in usual manner here at ten o’clock at night; and remember that no excuse can be accepted for failure.
Here was another glimpse of the Black Star’s work. Verbeck, after a moment’s thought, decided to give the man his orders and let him go. He would continue to play at being the Black Star and discover all he could of the master crook’s plans. Perhaps he would be able to prevent the wholesale theft of valuable jewels; for it appeared that the Black Star intended a series of crimes following the Charity Ball. This man before him had orders to report the following night, so there was no object in exciting his suspicions now.
Verbeck would have given a great deal at that moment to have been able to peer behind the other man’s mask. Who was this man before him who could be expected to engage Miss Freda Brakeland in conversation without arousing suspicion? Somebody who belonged in the city, surely, somebody well known in society, for Freda Brakeland was one of the most exclusive and unapproachable women of the younger set.
Verbeck was annoyed by the Black Star’s threat that the chickens might come home to roost. He was astounded at the lines of information gathered for the benefit of the master crook, and a multitude of questions rushed to his mind, none of which he could answer. He decided to refrain from calling in the police at present, at least until he discovered more.
And now to Verbeck came another plan he decided to use. He placed the orders on the end of the table and motioned for the other man to pick them up; then he hurried to his blackboard and wrote supplementary orders there:
Pass the northwest corner of First Avenue and American Boulevard at exactly two o’clock in afternoon on your way to the hotel. Stop on corner, remove hat, and pretend to brush dust from it. If there is to be any change in your orders, an envelope will be slipped to you at that time; otherwise, go ahead as you have been directed.
It seemed to Verbeck that the other man expressed surprise in the way his shoulders straightened and his head lifted, and for an instant Verbeck feared he had attempted too much. But the other only nodded that he understood, then saluted and backed out of the door. Two minutes later Muggs came in from the other room and reported that the crook had put robe and mask in the box outside, and had hurried away.
“I’ll get him!” Verbeck said. “He’ll stop on that corner and give the sign, and then I’ll follow him. I’ll learn who it is that’s helping the Black Star gather valuable information. We’ve got to stick to the game now, Muggs, old man!”
“I’d call the police——”
“Not yet! I’m going to play this game myself until it gets too hot for me. The Black Star challenged me, didn’t he? I’ll have plenty of evidence before I call in the police.”
“What about the chief crook in the other room? He’s conscious again.”
Verbeck paced the floor for a time, his head bowed, thinking.
“I have it!” he exclaimed at last. “You get out of here, Muggs, and hurry to the garage and get my car. Stop at the rooms and get that bunch of keys in the right-hand drawer of my desk——”
“The keys to the old place?”
“Yes. We’ll take the Black Star there, Muggs. Bring the car to the corner nearest this house, then hurry in and help with him. We’ve got to have it done before dawn. Hurry! That’s what we’ll do, Muggs! We’ll take the Black Star to the old house, and there you’ll guard him, while I play master crook in his mask and robe.”
CHAPTER V—MUGGS ON GUARD
When Muggs had departed Verbeck got up and walked into the other room, where the Black Star was on the floor in an uncomfortable position. Muggs had left the window open, and the cold air swept in, bringing sleet and snow with it. It had been all one with Muggs whether the Black Star froze to death or not.
Verbeck closed the window. He didn’t want to carry the man into the furnished room for fear some other member of the gang might come to make a report, although now it was almost three o’clock in the morning. So he threw the door open wide and rolled in the couch and lifted the Black Star upon it, covering him with two heavy portières that hung before one of the doors. However, there was no expression of thanks in the Black Star’s countenance.
Verbeck went back into the other room and closed the door behind him. He took a candle from a shelf in the corner and lighted it, then made an inspection of the house from bottom to top. No other room was furnished; there were no arrangements for cooking, no store of food. The Black Star, then, did not live here, only came here to receive the members of his gang. That would make it possible for Verbeck to remain away from the house except at night.
He went back to the furnished room and conducted an investigation there. First he looked at the orders in the envelopes. Nine was the highest number there, but Verbeck did not know how many envelopes had been given out that night before his arrival. And the orders were astounding.
Only one had to do with gathering information; the others concerned projected crimes. Some of them Verbeck could not understand, since they referred to orders given previously. But others indicated not only
