"In that safe," said the doctor, pointing to a steel box in the corner, "there is enough to start you. I have about five thousand dollars in cash there, and I will send ten times as much more after you. Is that enough?" "You take my breath away," said Nick. "When must I go?" "At once; to-night." "But, Dr. Jarvis--" "Don't talk. Do it. If fifty thousand dollars isn't enough, you shall have a hundred thousand within six months." "How do I know that you will send it?" "If I don't, come back and denounce me." "But how will you explain my going?" "I will say that you have gone to Europe for me as you did go three years ago." Nick shook his head. "Dr. Jarvis," said he, "I've worked for you twenty years, and I think as much of you as of any man living, but I can't do this." "Why not?" "I can't shield a guilty man." "Nonsense, you idiot; I am as innocent as you are." "Then why do you send me away? No, Dr. Jarvis, this is plain to me. You killed him." "I killed him?" cried the doctor. "Yes; but you are not a murderer at heart. Some accident led to this. Tell me how it happened, and if it is as I think, I will go." "I tell you I am innocent. I had nothing to do with this man's disappearance." Despite all Nick's ingenuity, Dr. Jarvis stuck to this assertion. There was nothing left for Nick, in the character of Cleary, except to pretend to believe it. He resolved to accept the doctor's bribe. This was almost necessary, for in any case he would be obliged to remove Cleary. After this conversation, it would not be safe to leave the negro there. The doctor would, of course, discover that some trick had been played upon him as soon as he mentioned the events of the night to Cleary. The results which would follow such a discovery Nick wished to avoid. He, therefore, with great caution, accepted the proposal, and received a large sum as the first installment of the blackmail. As to the doctor's real intentions, Nick was in some doubt. It seemed probable that he meant to sacrifice Cleary to secure his own safety in case it became necessary. If Cleary ran away, it would be easy to divert suspicion to him. The case against Dr. Jarvis looked very plain. Innocent men do not take such desperate measures. And yet Nick was far from reaching a definite opinion in the case. He returned to Cleary's room; and it required a good deal of skill to keep the doctor out of it. If he had entered, and had seen two Cleary's, it is hard to say what desperation would have led him to do. For an instant Nick had an idea of letting him do it, and then attempt to secure a true statement of the case with the aid of the shock which the doctor would have sustained on discovering how he had been duped. But second thought showed him the necessity for a different procedure. From Cleary's window he signaled for Chick, who was in waiting near the wall, and to him he delivered the unconscious form of the negro.
