"Now, if Cutts paid them—and Cutts is crooked, if he is a detective; I've known that this long while—the question is who was to pay Cutts? My answer would be this man Callister, whose direct interest it is to have you convicted of crime."

"Mr. Hook," exclaimed the boy, lost in astonishment, "I am completely bewildered. What would you advise me to do?"

"To place yourself in my hands, if you will," answered the detective, decidedly. "I will take up your case if you wish me to do so, for it is just the sort of an affair I like.

"I now fully believe your story, my boy, and shall not place you under arrest. In working for your interests I shall also be doing my duty in unearthing the robbers of the Webster Bank."

"Of course I shall be only too glad of your help," said Frank, eagerly. "I have been foolish—I see it now. Whatever you say I'll do."

"Then, inasmuch as you have mysteriously disappeared, remain so. I've reported your disappearance to the police; let it be your care not to reappear until I say the word.

"Disguise yourself, watch Callister, see your bootblacks and newsboys, and procure from them the tin box and all it contains. I will do for your unfortunate mother all that can be done. When you want money come to me. We will work together, Frank, and as I don't work for nothing, you can repay me when you come into your own."

"I can never repay you, sir!" cried the boy, with tears in his eyes, grasping the detective's outstretched hand.

"Yes, you can, and I'm sure you will. Here are a few dollars now. When you need it you shall have more. Now go, and don't be seen in the streets so dressed that any one will recognize you again. You can meet me—let me see—I've got to go out of town this afternoon on important business, and won't return until late to-night. Meet me where I saw you first—on the corner of Rector street and Broadway—to-night, as the clock of old Trinity strikes twelve."
