Of course the lawyer was astonished at the news, and asked what steps had been taken to apprehend the thief. When told that the authorities had been asked to take charge of the case, he wanted to know if he could be of any assistance.

"I don't see how you can help us, Mr. Powell," answered Dick, over the wire. "I suppose we will have to put the whole matter in the hands of the police."

"Well, if I can do anything at all, let me know," answered Songbird's uncle. "I am rather busy now, but as soon as I am at leisure, I will call and talk the matter over with you."

Inside of half an hour the two detectives from headquarters arrived. They were bright, sharp-eyed individuals, and they got down to business without delay. They asked Dick innumerable questions, and looked carefully at the safe, trying the combination several times, and then inspected the offices and the hallway. After that they subjected Kittie Donovan to a close examination, getting the girl to tell everything she could possibly think of regarding the strange man she had seen on the evening when the robbery had occurred.

"I think I know who did this job," said one of the detectives to the other.

"Looks like the work of one of three men to me," returned the other sleuth. "Baldy Jackson, Slim Martin, or Hank the Bluffer."

"You may be right, Joe, but I think it was Hank. If I've got the dope right, those other two fellows you mention are not near New York just now."

"Well, if Baldy and Slim can prove that they weren't around New York at the time, then I'll agree with you that it was Hank who lifted that box," returned the other detective.

"Who is this Hank the Bluffer?" questioned Dick, curiously.

"Oh, he's an old one at this sort of game," returned one of the detectives. "He is a wonder at opening safes. Somebody told me once that he made the assertion he could open any ordinary office safe inside of fifteen minutes. He's got it all in his finger ends. They are so sensitive that when he turns the safe knob, he can feel every movement of the tumblers inside."
