Fix looked intently at his companion, whose countenance was as serene as possible, and laughed with him. But Passepartout persisted in chaffing him by asking him if he made much by his present occupation. "Yes, and no," returned Fix. "There is good and bad luck in such things. But you must understand that I don't travel at my own expense." "Oh, I am quite sure of that!" cried Passepartout, laughing heartily. Fix, fairly puzzled, descended to his cabin and gave himself up to his reflections. He was evidently suspected; somehow or other the Frenchman had found out that he was a detective. But had he told his master? What part was he playing in all this. Was he an accomplice or not? Was the game, then, up? Fix spent several hours turning these things over in his mind, sometimes thinking that all was lost, then persuading himself that Fogg was ignorant of his presence, and then undecided what course it was best to take. Nevertheless, he preserved his coolness of mind, and at last resolved to deal plainly with Passepartout. If he did not find it practicable to arrest Fogg at Hong Kong, and if Fogg made preparations to leave that last foothold of English territory, he, Fix, would tell Passepartout all. Either the servant was the accomplice of his master, and in this case the master knew of his operations, and he should fail; or else the servant knew nothing about the robbery, and then his interest would be to abandon the robber. Such was the situation between Fix and Passepartout. Meanwhile Phileas Fogg moved about above them in the most majestic and unconscious indifference. He was passing methodically in his orbit around the world, regardless of the lesser stars which gravitated around him. Yet there was near by what the astronomers would call a disturbing star, which might have produced an agitation in this gentleman's heart. But no! The charms of Aouda failed to act, to Passepartout's great surprise; and the disturbances, if they existed, would have been more difficult to calculate than those of Uranus which led to the discovery of Neptune. It was every day an increasing wonder to Passepartout, who read in Aouda's eyes the depths of her gratitude to his master. Phileas Fogg, though brave and gallant, must be, he thought, quite heartless. As to the sentiment which this journey might have awakened in him, there was clearly no trace of such a thing; while poor Passepartout existed in perpetual reveries. One day he was leaning on the railing of the engine room, and was observing the engine, when a sudden pitch of the steamer threw the screw out of the water. The steam came hissing out of the valves; and this made Passepartout indignant. "The valves are not sufficiently charged!" he exclaimed. "We are not going. Oh, these English! If this was an American craft, we should blow up, perhaps, but we should at all events go faster!" Chapter 18 In Which Phileas Fogg, Passepartout and Fix Go Each about His Business
