"And Nicholas Crafer was mine," replied the other, "and he found it, too. It belonged to him as much as to Simon, and, what's more, the secret belongs to me and not to you. And as you are a card player and a 'sportsman,' Mr. Alderly, you'll understand what a strong card that is in my favour."

It was so strong a card that Alderly acknowledged to himself in his own phraseology that "he was beat." That is, he was "beat" by fair means, and, being a brute and a savage in whose nature there seemed to run all the worst strains of his ancestor, Simon, he soon took to turning over in his mind how he could win by means that were foul.

And on how these means could be brought about he pondered deeply, roaming round the island as he did so, Barbara's gun under his arm with which to shoot, now and again, a gull or some other equally harmless or useless bird; or sitting on the crags, or the beach when the tide was out, thinking ever. And what he thought about more than anything else was, "How could he obtain possession of that paper which he had seen in Grafer's hand?" For in that paper lay the secret, he felt sure, of the spot to which the treasure, his treasure, had been removed.

It may be told here that, although he had been outside the jalousie on the night of the storm which drove him home, and his father to his doom, for longer than either Barbara or Reginald knew, he had gleaned but a very imperfect knowledge of what the latter had read out. Some words he had caught, such as "when you have taken your first measurement from the spot where you land, you stick in the ground your sword, and then make, or persevere until you make, all your other strides correspond with what I have wrote down." Yet this told nothing. He had not heard nor caught the mention of the Keys, therefore the measurement might apply to any of the scores of little islands in the Virgin Archipelago. Also he had heard Reginald read out from his papers, "now here is a little map, rough as befits a drawing made by me, yet just and true." But of what use was this map--unless he could set eyes on it! Ah! that was it. If he could set eyes on it!

He had heard other sentences, too; a portion of the conclusion of Nicholas Crafer's narrative, but they would not piece together into one explicit whole. He was, indeed, at bay. He knew the treasure had been moved somewhere, and he knew that, in the possession of this fellow who was now in that gimcrack yacht in the river, was a description of where the treasure was, as well as a map showing the spot; but he knew no more.

And as he thought it all over, sitting upon a crag, he ground his large white teeth and beat the rock beneath him with the butt of Barbara's gun in his rage. But, at last, it seemed that he had made up his mind, had resolved upon his plan; for with a smothered oath--the use of which expletives he was very frequent in--he sprang to his feet, while he muttered to himself--

"One half! One half! Ho! Ho! No! Not one half, not one shilling, not one red cent."

As he rose, there came across the little grassy plateau behind the crag his sister, Barbara. For a moment she paused and glanced at him, and, perhaps because she knew him so well and had studied all his evil moods from infancy, she observed something in his face more evil, more threatening than usual. Then she said--

"I want my gun."

"What for?"
