Final Proof Part 34

Mr. Mitchel turned to his safe and brought out a box which Mr. Barnes thought he recognized. Opening it he drew out a marvellous string of pearls, which he laid aside, while he took from beneath, a velvet case which contained the opal. Returning the pearls to the box he restored that to the safe, which he locked.

"Now, if you will let me see your opal," said Mr. Mitchel, "I will compare the gems."

"Here it is," said Mr. Livingstone, handing Mr. Mitchel his opal.

Mr. Mitchel took the two opals in his hand, and, as they lay side by side, he examined them closely, observing the play of light as he turned them in various positions. To his critical eye they were marvellously beautiful; matchless, though matched. None could see these two and wonder that the old priests in Mexico had searched in vain for a second pair like them.

"Do you know why these opals are so exactly alike?" asked Mr.

Livingstone.

"I am not sure," said Mr. Mitchel, apparently absorbed in his scrutiny of the opals. "I have heard many reasons suggested. If you know the true explanation, suppose you tell me."

"Willingly. You will observe that in each opal red lights seem to predominate on one side, while the blue and green are reflected from the other. Originally, this was one great egg-shaped opal, and it was cut in that shape, and then poised in the forehead of a single-eyed idol by the priests of a thousand years ago. By an ingenious mechanism the eye could be made to revolve in its socket, so that either the red or the blue-green side would be visible, as it suited the purpose of the priests, when overawing the tribesmen by pretended prophecies and other miraculous performances. In more recent times, since the advent of the Christians, one-eyed idols are not so plausible, and the priests cut the opal in half, thus making it serve in what may be termed a modernized idol."

"Yes, I have heard that tale before. In fact, I have a metal ring which I was told would exactly encircle the two opals, if placed together to form an egg."

"How could you have such a thing?" asked Mr. Livingstone, with genuine surprise.

"The man who stole the jewels, so the story goes, wishing to enhance their value as much as possible, arranged this as a scheme by which the genuineness of the opals could be tested. He placed the opals together, as before they were cut, and had a silver band made which would exactly clasp them in that position. This band opens and shuts with a spring catch, like a bracelet, and as, when closed, it exactly fits the opals, holding the two firmly together, the owner of the band could easily tell whether the true opals were before him, or not. In some way the opals were next stolen without the band, and their whereabouts was unknown when a dealer in Naples told me the story of the silver band, which he offered to sell me. I scarcely credited his tale, but as all large jewels might in time be offered to me, I thought it well to purchase the band."

"Why, then, if you still have it, it would be interesting to make the test, would it not?"

"Yes, I think so. I will get the band."

Mr. Mitchel placed the two opals on the desk before him and went over to the safe, where he was occupied some time opening the combination lock.

While he was thus busy a strange thing seemed to occur. At least it seemed strange to Mr. Barnes. He had marvelled to see Mr. Mitchel place the two opals within easy reach of Mr. Livingstone, and then deliberately turn his back while he opened the safe. But what seemed more mysterious was Mr. Livingstone's action. Mr. Mitchel had scarcely stooped before the safe when his guest leaned forward, with both arms outstretched simultaneously; his two hands grasped the opals, the hands then swiftly sought his vest pockets, after which he calmly puffed his cigar. Thus he seemed to have taken the opals from the table and to have placed them in his pockets. Yet how could he hope to explain their absence to Mr. Mitchel? This thought flashed through Mr. Barnes's mind as his eyes instinctively turned again to the desk, when, to his utter astonishment, he saw the opals exactly where Mr. Mitchel had placed them. Had the thought that he could not explain away the disappearance caused the man to change his mind at the very moment when he had impulsively clutched the treasures? Mr. Barnes was puzzled, and somewhat worried too, for he began to fear that more had happened, or was happening, than he comprehended.

"Here is the band," said Mr. Mitchel, returning to the desk, and resuming his seat. "Let us see how it fits the opals. First, let me ask you, are you confident that you are selling me one of the genuine Aztec opals?"

"I am. I have a history which makes its authenticity indubitable."

"Then we will try our little test. There; the band clamps the two perfectly. Look for yourself."

"Certainly; the test is complete. These are undoubtedly the Aztec opals.

Mr. Mitchel, you are to be congratulated upon gaining possession of such unique gems."

Mr. Livingstone arose as though about to leave.

"One moment, Mr. Livingstone; the jewels are not mine, yet. I have not paid you for yours."

"Oh, between gentlemen there is no hurry about such matters."

"Between gentlemen it may be as you say. But you said this was to be strictly in accordance with business methods. I prefer to pay at once.

Here is my certified check. I will also ask you to sign this receipt."

Mr. Livingstone seemed to hesitate for a moment. Mr. Barnes wondered why? He sat at the desk, however, and, after reading the receipt, he signed it, and took the check, which he placed in his pocketbook, saying:

"Of course we will be businesslike, if you insist, though I did not antic.i.p.ate that you would take me so literally. That being over, Mr.

Mitchel, I will bid you good morning."

"You may go, Mr. Livingstone, when the transaction is over, but not before."

"What do you mean?" demanded Mr. Livingstone aggressively, as he turned and faced Mr. Mitchel, who now stood close beside him.

"I mean that you have accepted my money. Now I wish you to give me the opal."

"I do not understand. There are your opals, just where you placed them on the table."

"We will have no quibbling, Mr. Livingstone. You have taken twenty-five thousand dollars of my money, and you have given me in exchange a worthless imitation. Not satisfied with that, you have stolen my genuine opal."

"d.a.m.n you----"

Mr. Livingstone made a movement as though to strike, but Mr. Mitchel stepped quickly back, and, quietly bringing forward his right arm, which had been held behind his back, it became evident that he held in his hand a revolver of large calibre. He did not raise the weapon, however, but merely remarked:

"I am armed. Think before you act."

"Your infernal accusation astounds me," growled Mr. Livingstone. "I hardly know what to say to you."

"There is nothing to say, sir. You have no alternative but to give me my property. Yes, you have an alternative,--you may go to prison."

"To prison!" The man laughed, but it was not a hearty laugh.

"Yes, to prison. I believe that is the proper lodging-place for a thief."

"Take care!" cried Mr. Livingstone, advancing upon Mr. Mitchel.

"Mr. Barnes," said Mr. Mitchel, still without raising his weapon. At this the man stopped as quickly as he had when the weapon was first shown. He seemed confounded when the detective stepped into view.

"Ah," he sneered; "so you have spies upon your guests?"

"Always, when my guests are thieves."

Again the words enraged him, and, starting forward, Mr. Livingstone exclaimed:

"If you repeat those words, I'll strangle you in spite of your weapon and your spy."

"I have no wish to use harsh language, Mr. Livingstone. All I want is my property. Give me the two opals."

"Again I tell you they are on your desk."

"Where are the genuine opals, Mr. Barnes? Of course you saw him commit the--that is, you saw the act."

"They are in his vest pocket, one in each," said the detective.

"Since you will not give them to me, I must take them," said Mr.

Mitchel, advancing towards Mr. Livingstone. That gentleman stood transfixed, livid with rage. As his antagonist was about to touch his vest pocket, his hand arose swiftly and he aimed a deadly blow at Mr.

Mitchel, but not only did Mr. Mitchel as swiftly lower his head, thus avoiding the blow, but before another could be struck, Mr. Barnes had jumped forward and grasped Mr. Livingstone from behind, pinioning his arms and holding him fast by placing his own knee in his adversary's back. Mr. Livingstone struggled fiercely, but almost instantly Mr.

Mitchel took the opals from his pockets, and then quietly remarked:
