By the time the last voyage of the Sea Fox had been made and she returned to The Pocket, the relations between Wolf and the Indian were in danger of rupture. Wolf distrusted his partner, and yet believed he had lulled all suspicion. He had never failed before in duping any one he had set out to; why should he in this case? Still, he was uneasy and resolved to end it all as soon as possible. But Indians have one peculiarity that will baffle even the shrewdest Jew. They never talk. Their faces are always as expressionless as a graven image. While contemplating the most cruel murder they never show the least change in expression, nor do their eyes show the faintest shadow of an emotion. They are stolid, surly and Sphinx-like always. Wolf's partner was like his race, and not even by the droop of an eyelid did he betray the slowly gathering storm of hate and rage within. He brooded over the hurt he felt when Wolf had wanted to buy his sloop, and believing the Jew meant to rob him of her, he grew suspicious and watched Wolf. Not by word or sign did he show it, and the Jew saw it not. Wolf watched the Indian as closely, only the Indian knew it, and Wolf did not. It was now Wolf against fox and fox against Wolf, and the swarthy fox was getting the best of it. Meanwhile the loading of the sloop for her final departure proceeded. Wolf had planned to use the Indian's help to the last, and when all was ready, enter the cave, secure the money about his person and sail away. The cave entrance was under water for about two hours of high tide, and Wolf waited until a day came when the tide served early. He had planned to go in just before the rising water closed the entrance, thus securing himself from intrusion; and then, when the tide fell away, to come out ready to start. The day and hour came and he entered the cave. Unknown to him the Indian followed! Wolf lighted a lamp and sat down. When the sea had closed the entrance, no sound entered. Wolf waited. Ten, twenty, thirty minutes passed, and all sound of the ocean ceased. He believed himself alone. He lighted the other lamp, placing both on the flat rock. Then he went to the rocking stone, and pushing it back, took from the niche, one by one, the bags of coin. These he carried to the table stone and poured their contents into a glittering pile. From behind a rock a pair of sinister eyes watched him!
