"Mr. Gray himself. You see, your assistants are not all so clever as yourself, though I doubt not this girl may think that she is a genius. You told her to seek a position in the house, and what does she do? She goes straight to Mr. Gray and tells him her purpose; hints that it might be well for him to know just what really actuated Mrs. Gray in the curious affair on the yacht, and agrees to 'discover everything'--those were her words--if he would give her the opportunity. Poor man, she filled his mind with dire suspicions and he managed it so that she was taken into service. Up to the present time she has discovered nothing. At least, so she tells him."
"The little she-devil! You said that she explained her whole purpose. Do you mean----"

"Oh, no. She did not implicate you, nor divulge her true mission. The fun of the thing is that she claimed to be a 'private detective' and that this venture was entirely her own idea. In fact, she is working for Mr. Gray. Is not that droll?" Mr. Mitchel threw back his head and laughed heartily. Mr. Barnes did not quite see the fun, and looked grim. All he said was:

"She acted beyond her instructions, yet it seems that she has not done any harm; and though she is like an untamed colt, apt to take the bit between her teeth, still she is shrewd. But I'll curb her yet. Now as to your third fact. How did you know that I had Mr. Moore watched, and only for two or three days?"

"Why, I recognized one of your spies following him one day down Broadway, and as Moore sailed for Europe two days after, I made the deduction that you had withdrawn your watch-dog."
"Well, then," said Mr. Barnes, testily, "how did you know that I had, as you declare, 'discovered Pedro Domingo'?"
"How did I know that? Why--but that can wait. You certainly did not call this morning to ask me all these questions. You came, as I presume, to convey information."
"Oh, you know so much, it is evidently unnecessary for me to tell you of my trifling discoveries." Mr. Barnes was suffering from wounded pride.
"Come, come," exclaimed Mr. Mitchel, cheerily, "be a man; don't be downcast and fall into the dumps merely because I surprised a few trifling facts in your game, and could not resist the fun of guying you a little. You see, I still admit that what I know are but trifling facts; what you know, on the contrary, is perhaps of great importance. Indeed, I am assured that without your information, without a full knowledge of all that you have discovered, my own plans may go awry, and then the danger at which you hint might be all too real. Do you not see that, knowing that you are interested in this case, I have been only too willing to let half the burden of the investigation fall upon you? That to your skill I have intrusted all of that work which I knew you could do so well? That in the most literal sense we have been silent partners, and that I depended upon your friendship to bring you to me with your news, just as it has brought you?"
