"You say that you love Miss Brunell, Guy, and because of that, you will have nothing further to do with an investigation which points primarily to her father as an accomplice in the crime. Do you realize that if you throw over the case now, I shall be compelled to put another operative on the trail, with all the information at his disposal which you have detailed to me? You may be sure the man I have in mind will have no sentimental scruples against pushing the matter to the end, without regard for the cost to either Jimmy Brunell or his daughter. Naturally, being in love with the girl, her interests are paramount with you. I, too, desire heartily to do nothing to cause her anxiety or grief. Remember that I have daughters of my own. As I have told you, I firmly believe that the old forger is merely a helpless tool in this affair, but my duty demands that I obtain the whole truth. If you repudiate the case now, give up your career, and go to work single-handed to attempt to protect her and her father by thwarting my investigation, you will be doing her the greatest injury in your power. The only way to help them both is to do all that you can to discover the real facts in the case. When we have succeeded in that, we shall undoubtedly find a way to shield old Jimmy from the brunt of the blame. "Don't forget the big interests, political and municipal, at work in this conspiracy. They would not hesitate to try to make the old offender a scape-goat, and you know what sort of treatment he would receive in the hands of the police. Play the game, Guy; stick to the job. I'm not asking this of you for my own investigation. I have a dozen, a score of operatives who could each handle the branch you are working up just as well as you. I ask it for the sake of your career, for the girl herself, and her father. I tell you that instead of incriminating old Jimmy, you may be the means of ultimately saving him.--Go back to Emily Brunell now, get that letter from her by hook or crook, and bring it to me." The detective paused at length and waited for his answer. It was long in coming. Guy Morrow stood leaning against his desk, his brows drawn down in a troubled frown. Blaine watched the outward signs of his mental struggle warily, but made no further plea. At last the young operative raised his head, his eyes clear and resolute, and held out his hand. "I will, sir! Thank you for giving me another chance. I do love the girl, and I want to help her more than anything else in the world, but I'll play the game fairly. You are right, of course. I can be of more assistance to her on the inside than working in the dark, and it would be better for everyone concerned if the truth could be brought to light. I'll get the letter, and bring it to you to-night."
