"They will not be here before another ten minutes," said Nikola, consulting his watch; "we had a good start of them."
Seating ourselves we awaited their arrival, and while we did so, Nikola talked of the value set upon human life by the inhabitants of different countries. No one was more competent to speak on such a subject than he, for he had seen it in every clime and in every phase. He spoke with a bitterness and a greater scorn for the petty vanities and aims of men than I had ever noticed in him before. Suddenly he stopped, and looking towards the left said--
"If I am not mistaken, the Duke of Glenbarth has arrived."
I looked in the direction indicated, and was able to descry the tall figure of the Duke coming along the sands. A little later two other persons made their appearance and followed him. One was undoubtedly the Don, but who was the third? As they drew closer, I discovered that he was unknown to me; not so to Nikola, however.
"Burmaceda," he said to himself, and there was an ugly sneer upon his face.
The Duke bowed ceremoniously to the two men, and the stranger, having returned his salute, knelt upon the sand, and proceeded to open a box he had brought with him. From it he produced a pair of pistols which he loaded with ostentatious care. This work finished, he took them by their barrels and gave Glenbarth his choice. The Spaniard, I noticed, was dressed entirely in black, not showing a particle of white; the Duke was attired very much as usual. When each had taken a pistol, the stranger measured the distance upon the sands and allotted them their respective positions. By this time I was in such a fever of excitement that Nikola laid his hand upon my arm to restrain me.
"Wait," he whispered. "Have I not pledged you my word that your friend shall not be hurt? Do not interrupt them yet. I have my suspicions, and am anxious to confirm them."
[Illustration: "'Put down your pistols,' said Nikola."]
I accordingly waited, but though it was only for a few seconds it seemed to me an eternity. The two men were in position, and the stranger, I gathered, was giving them their final instructions. They were to stand with their faces turned from each other, and at the word of command were to wheel round and fire. In a flash I saw what Nikola had in his mind. The stranger was favouring the Don, for while Glenbarth would have faithfully carried out his portion of the contract, the Spaniard did not turn at all, a fact which his opponent was scarcely likely to become aware of, seeing that he would in all probability have a bullet in his heart before he would have had time to realize the trick that had been played upon him. The stranger had raised his hand above his head, and was about to give the signal, when Nikola sprang from beside me, and in a loud voice called to them to "stop." I rose to my feet at the same instant, and followed him across the sands to where the men stood.
