Final Proof Part 31

Gray was lying. Now tell me how you recovered the jewel."

"That was easier than I expected. When I got him alone, I simply told Mr. Livingstone what I knew, and asked him to hand me the opal. With a perfectly imperturbable manner, understanding that I promised secrecy, he quietly took it from his pocket and gave it to me, saying:

"Women are very poor conspirators. They are too weak."

"What story did you tell Mr. Gray?"

"Oh, he would not be likely to inquire too closely into what I should tell him. My check was what he most cared for. I told him nothing definitely, but I hinted that his wife had secreted the gem during the darkness, that he might not ask her for it again; and that she had intended to find it again at a future time, just as he had meant to p.a.w.n it and then pretend to recover it from the thief by offering a reward."

"One more question. Why did Mr. Livingstone steal it?"

"Ah; the truth about that is another mystery worth probing, and one which I shall make it my business to unravel. I will venture a prophecy.

Mr. Livingstone did not steal it at all. Mrs. Gray simply handed it to him in the darkness. There must have been some powerful motive to lead her to such an act; something which she was weighing, and decided impulsively. This brings me to a second point. Livingstone used the word conspirators; that is a clue. You will recall that I told you that this gem is one of a pair of opals, and that with the other, the two would be as interesting as any jewels in the world. If anyone ever owns both it shall be your humble servant, Leroy Mitchel, Jewel Collector."

VII

THE DUPLICATE HARLEQUIN

One day about two weeks after the unravelling of the mystery of the opal lost on board the yacht _Idler_, Mr. Barnes called upon Mr. Mitchel and was cordially received.

"Glad to see you, Mr. Barnes. Anything stirring in the realm of crime?"

"'Stirring' would be a fitting adjective, I think, Mr. Mitchel. Ever since the _Idler_ affair I have occupied myself with a study of the problem, which I am convinced we have but partially solved. You may recall that you gave me a clue."

"You mean that Livingstone, when he gave me the opal, remarked, 'Women are poor conspirators.' Yes, I remember calling your attention to that.

Has your clue led to any solution?"

"Oh, I am not out of the maze yet; more likely just entering the most intricate depths. Still, I flatter myself that I have accomplished something; enough to satisfy me that 'mischief is brewing,' and that the conspirators are still conspiring. Moreover, there is little doubt that you are deeply concerned in the new plot."

"What! You insinuate that I am in this conspiracy?"

"Only as a possible victim. You are the object of the plot."

"Perhaps you think that I am in danger?" Mr. Mitchel smiled as though the idea of danger were a pleasurable one.

"Were you any other man than yourself, I should say most decidedly that you are in danger."

"But, being myself, you fancy that the danger will pa.s.s from me?"

"Being yourself, I antic.i.p.ate that you will compel the danger to pa.s.s from you."

"Mr. Barnes, you flatter me. Perhaps I may be able to thwart the conspirators, now that you warn me; if I do, however, I must admit my great indebtedness to you. To be forewarned is to have the fight half won, and I candidly say that I was entirely unsuspicious of any lurking danger."

"Exactly. With all your ac.u.men, I was sure that your suspicions had not been aroused. The conspirators are wary, and, I a.s.sure you, unusually skilful. So, under all the circ.u.mstances, I felt it my duty to be on the alert."

"Ah, I see," said Mr. Mitchel, in that tone peculiar to him, which made it doubtful whether he spoke in earnest, or whether his words hid keen satire. "The old cat being asleep, the kitten watches. That is very nice of you. Really, it is quite a comforting thought that so skilful a detective is ever guarding my person. Especially as I am the owner of so many gems to which the covetous must ever look longingly."

"That is just how I reasoned it," said Mr. Barnes, eagerly, wishing to justify his actions, which he began to suspect Mr. Mitchel might resent.

"You explained to me your reasons why you have purchased so many valuable jewels. You claimed that almost every large gem has been the cause, or rather the object, of crime. The Aztec Opal came into your possession under most peculiar circ.u.mstances. In fact, you thwarted a criminal just as he had come into possession of it. But this criminal is a wealthy man. Not perhaps as rich as yourself, but rich enough to be above stealing even such a valuable bauble. It could not have been the intrinsic value of the opal which tempted him; it must have been that some special reason existed; some reason, I mean, for his acquiring possession of this particular opal. All this being true, it would be a natural sequence that his efforts to get the opal would not cease merely because it had changed hands."

"Your argument is most interesting, Mr. Barnes, especially as it is without a flaw. As you say, from all this reasoning it was a natural sequence that Mr. Livingstone would continue his quest for the opal.

This being so obvious, did you imagine that it had escaped me?"

Mr. Barnes was confused by the question. He really admired Mr. Mitchel very much, and though he considered him quite conceited, he also admitted that he had great a.n.a.lytical powers and remarkable ac.u.men. He also, more than anything else, desired a perpetuation of his friendship; indeed, it had been with an idea of increasing the bond between them that he had called. He had spent much of his time, time which could have been occupied with other matters to better financial advantage, and all with the purpose of warding off from his friend a danger which he had at first considered as a distant possibility, but which later he looked upon as certain, if nothing intervened to hinder the plot, which he knew was rapidly approaching the moment of execution. He therefore hastened to make further explanation:

"Not at all--not at all. I am merely indicating the steps by which I reached my conclusions. I am giving you my reasons for what I fear you now may consider my interference in your affairs. Yet I a.s.sure you I meant it all----"

"For the best. Why, of course, my friend; did you suppose that I doubted your good intent, merely because I spoke brusquely?" Mr. Mitchel held out his hand cordially, and Mr. Barnes grasped it, glad to note the altered demeanor of his companion. Mr. Mitchel continued: "Will you never learn that my weakness is for antagonizing detectives? When you come here to tell me that you have been 'investigating' my private affairs, how could I resist telling you that I knew all about it, or that I could take care of myself? I would not be Leroy Mitchel were it otherwise."

"How do you mean that you know all about it?"

"Well, perhaps not all. I am not exactly omniscient. Still, I know something. Let me see, now. How much do I know? First, then, you have had this Livingstone watched. Second, you have introduced one of your spies, a young woman, into the home of Mrs. Gray. In spite of your alleged faith in Dennett Moore, you had him watched also, though for only two or three days. Lastly, you have discovered Pedro Domingo, and----"

"In Heaven's name, Mr. Mitchel, how do you know all this?" Mr. Barnes was utterly dumbfounded by what he had heard.

"All this?" said Mr. Mitchel, with a suave smile; "why, I have mentioned only four small facts."

"Small facts?"

"Yes, quite small. Let us run them over again. First, I stated that you had Mr. Livingstone watched. That was not hard to know, because I also had a spy upon his track."

"You?"

"Yes, I. Why not? Did you not just now agree that it was obvious that he would continue his efforts to get the opal? Being determined that I should never part with it whilst alive, it likewise followed that he must kill me, or have me killed, in order to obtain it. Under these circ.u.mstances it was only common caution to have the man watched.

Indeed, the method was altogether too common. It was _bizarre_. Still, my spy was no common spy. In that, at least, my method was unique.

Secondly, I claimed that you had introduced a woman spy into the home of Mrs. Gray. To learn this was even easier. I deduced it from what I know of your methods. You played the same trick on my wife once, I think you will recall. Supposing Mrs. Gray to be a conspirator (that was your clue, I think), you would hardly watch Livingstone and neglect the woman. Yet the actual knowledge came to me in a very simple manner."

"How was that?"

"Why, Mr. Gray told me."

"Mr. Gray told you?"

"Mr. Gray himself. You see, your a.s.sistants 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."
