With the Nicaraguan coast fairly astern, and the Andromeda picking her way gingerly among the cays and reefs which extend from fifty to one hundred miles off the eastern hump of the Central American camel, we soon made the open Caribbean, and our course was once more laid indefinitely to the south and east. If we were to hold this general direction we should bring up in due time somewhere upon the Colombian or Venezuelan coast of South America.

Watching my opportunity, I cornered Van Dyck on the bridge at a moment when he had relieved the man at the wheel; this on our second evening out from Gracias Á Dios. As I came up, he was changing the course more to the southward, and I asked him if we were slated to do the Isthmus and the Canal.

"I hadn't thought very much about it," he answered half-absently. "Do you think the others would like it?"

"The Isthmus is pretty badly hackneyed, nowadays," I suggested; "and for your particular purpose——"

"Forget it!" he broke in abruptly. And then: "It's a hideous failure, Dick, as you have doubtless found out for yourself."

"Which part of it is a failure—your experiment, or the other thing?"

"I don't know what you mean by 'the other thing'," he bit out.

"Then I'll tell you: You thought it wouldn't be such a bad idea to show Madeleine Barclay what a vast difference there is between yourself and Ingerson as a three-meal-a-day proposition; as a steady diet, so to speak, in an environment which couldn't very well be changed or broken. Wasn't that it?"

"Something of the sort, maybe," he admitted, rather sheepishly, I thought.

"And it isn't working out?"

"You can see for yourself."

"What I see is that you are giving Ingerson a good bit more than a guest's chance."

"You don't understand," he returned gloomily.

"Naturally. I'm no mind reader."

While the Andromeda was shearing her way through three of the long Caribbean swells he was silent. Then he said: "I'm going to tell you, Dick; I shall have a fit if I don't tell somebody. Madeleine has turned me down—not once, you know, but a dozen times. It's the cursed money!"

"But Ingerson has money, too," I put in.

"I know; but that is different. Can't you conceive of such a thing as a young woman's turning down the man she really cares for, and then letting herself be dragooned into marrying somebody else?"

"You are asking too much," I retorted. "You want me to believe that a sane, well-balanced young woman like Madeleine Barclay will refuse a good fellow because he happens to be rich, and marry the other kind of a fellow who has precisely the same handicap. It may be only my dull wit, but I can't see it."

"I could make you see it if you were a little less thick-headed," he cut in impatiently. And then he added: "Or if you knew Mr. Holly Barclay a little better."

It was just here that I began to see a great light, with Madeleine Barclay threatening to figure as a modern martyr to a mistaken sense of duty. Did she know that her father would make his daughter's husband his banker? And was she generously refusing to involve the man she loved?

"It ought to make you all the more determined, Bonteck," I said, after I had reasoned it out. "It is little less than frightful to think of—the other thing, I mean. Ingerson will buy her for so much cash down; that is about what it will amount to."

"Don't you suppose I know it?" he exclaimed wrathfully. "Good Lord, Dick, I've racked my brain until it is sore trying to think up some way of breaking the combination. You don't know the worst of it. Holly Barclay is in deep water. Strange as it may seem, his sister, Emily Vancourt, named him, of all the incompetents in a silly world, as her executor and the guardian of her son. The boy is in college in California, and next year he will come of age."

"And Barclay can't pay out?"

"You've said it. He has squandered the boy's fortune as he has Madeleine's. I don't know how he did it, but I fancy the bucket-shops have had the most of it. Anyway, it's gone, and when the fatal day of accounting rolls around he will stand a mighty good chance of going to jail."

"Does Madeleine know?" I asked.

"Not the criminal part, you may be sure. She merely knows that her father is in urgent need of money—a good, big chunk of it. And she also knows, without being told, that the man who marries her will be invited to step into the breach. Isn't it horrible?"

"You have discovered the right word for it," I agreed. And then: "You are not letting it stand at that, are you?"

He did not reply at once. From the after-deck came sounds of cheerful laughter, with Alicia Van Tromp's rich contralto dominating; came also the indistinguishable words of a popular song which Billy Grisdale was chanting to his own mandolin accompaniment. Presently Jack Grey's mellow tenor joined in, and in the refrain I could hear Conetta's silver-toned treble. It jarred upon me a little; and yet I tried to make myself believe that I was glad she was happy enough to sing. True to her word, she had consistently maintained the barrier quarrelsome between us; and Jerry Dupuyster was playing his part like an obedient little soldier.

"You'd say it was a chance for a man to do something pretty desperate, wouldn't you, Dick?" Van Dyck said, breaking the long pause in his own good time.

"I think you would be justified in considering the end, rather than the particular means," I conceded.

"I have had a crazy project up my sleeve—a sort of forlorn hope, you know. But after working out all of the details time and again, I've always weakened on it."

"Perhaps some of the details are weak," I suggested, willing to be helpful if I could.

"One of them is, and I can't seem to build it up so that it will seem reasonably plausible. Of course you know that I'd pay the father out of the prison risk in the hollow half of a minute if I could make it appear as anything less than sheer charity. But I can't do anything like that openly; and if I should do it in any other ordinary way, Madeleine would be sure to find out about it and argue that I was merely lowering myself to Ingerson's plane—paving the way with the money that she despises. And she'd turn me down again—with some show of reason. I am still sane enough to foresee that."

"If Miss Barclay only had some money of her own with which to buy her release from that unspeakable father of hers," I began.

"That would break the combination easily," he said. "And she did have money once; half of her mother's fortune was left to her—with her father as trustee. It went the same way as Barclay's own half, and the Vancourt trust fund."

With Conetta's voice in my ears I couldn't think straight enough to help him much. What I said was more an echo of my own growing determination regarding Conetta than anything else.

"I'd fight for my own, Bonteck; and I'd do it with whatever weapon came handiest," I declared; and then the return of the steersman whom Van Dyck had relieved put an end to the confidences for the time being.

With the sea routine resumed, and the Andromeda once more steaming free and footloose, a night and a day elapsed before I again had private speech with Van Dyck. As before, it was after dinner in the evening, and Van Dyck had sent one of the cabin stewards to ask me to join him in his stateroom. It was a matchless night, and I was lounging with the younger members of the ship's company on the after-deck when the steward came and whispered to me. We were all singing college songs with Billy Grisdale's mandolin for an accompaniment, and I was able to slip away unnoticed.

I found Van Dyck sitting at his table, stepping off distances on a spread-out chart with a pair of compasses, and somehow I fancied that the air of the luxuriously fitted little den was surcharged with the electricity of portent.

"You sent for me?" I queried.

"Yes; sit down and light your pipe," and he motioned me to a chair. "What are the others doing?"

"The young people, with the Greys, are on the after-deck, caterwauling with Billy, as you can hear. There is a bridge table in full blast in the saloon, with Mrs. Van Tromp, Aunt Mehitable, Holly Barclay and Ingerson sitting in. The Sanfords have disappeared—gone to bed, I imagine; and the major is in the smoking-room, guzzling hot toddies."

"Good!" was the brief rejoinder. "Everything quiet up forward?"

"Why, yes—for all I know to the contrary," I answered in some little surprise. "Why shouldn't it be quiet?"

For a moment Van Dyck seemed embarrassed. And his explanation, when he made it, was half halting.

"There has been some little trouble with—er—the crew, you know. Quite likely you haven't seen any signs of it. I—I've been trying to keep it under cover as well as I could."

"Trouble?—of what sort?" I demanded.

"Why—er—the only kind one ever has with a crew; something like a threatened mutiny, I believe."

I laughed aloud.

"A mutiny on a private yacht? Why, heavens and earth—your men don't have anything to do but to draw their pay and their breath!"

"I know; that is the way it would appear. But there is something behind—something you don't understand. If I should tell you that the Andromeda left New York with a quarter of a million dollars in her hold——"

"What's that?" I ejaculated, shocked into sudden and lively attention.

"You must forgive me, Dick, if I don't go into the particulars," he went on hastily. "I might say, with a good degree of truth, that it isn't altogether my own secret. But—but the fact remains."

"A quarter of a mil—Great Caesar!" I gasped. Then the deductive part of my brain began to fit the fragmentary admissions into a probable whole. All summer there had been flying rumors in the West India ports of a revolution brewing in one of the South American republics; an upheaval which was to be financed—in the interests of a great importing corporation—by New York capital. Could it be possible that Van Dyck had foolishly allowed his yacht to be made use of as a money transport?

"You don't mean to say that we have that money on board now?" I protested, when the possible consequences began to make themselves manifest.

"As it happens, we haven't," he replied, quite calmly. "That is why it took the Andromeda so long to make the run from New York to Havana. I was getting rid of the impedimenta."

"But if you've gotten rid of it, why should your crew—"

"That is just the point," he explained patiently. "The thing had to be done quietly, and proper precautions were taken at both ends of the line to keep anybody and everybody from finding out that we were carrying a small fortune between-decks. Still, I am afraid it did leak out. That little black-mustached fellow who turned up at Havana, and again in New Orleans——"

"That reminds me of something that occurred to me no longer ago than this morning's breakfast-time," I broke in; "a thing that I've been meaning to ask you about ever since. Manuel, the mulatto boy who usually serves breakfast, was invisible this morning, and he had a substitute."

"Well?"

"I was going to say that, if I'm not greatly mistaken, you have that same mysterious little man—minus the mustaches—on your payroll at this moment, Bonteck. He is the under-steward who goes by the name of Lequat; he was the man who substituted for Manuel this morning, and he was the man who came to me just now to tell me that you wanted me."

It was now Van Dyck's turn to sit up and take notice and he did both, emphatically.

"That fellow?—In the Andromeda?" he exclaimed.

"As I say—if I'm not much mistaken. I had a pretty good chance to familiarize myself with his face that night in the hotel dining-room in New Orleans, and I have a fairly decent memory for faces."

Van Dyck fell into a muse, breaking the silence finally to say: "By Jove, Dick, that may prove to be a horse of another color, don't you know!"

Waiving the question as to what the color of the original horse might have been, I stuck to the point at issue.

"If, as you say, you have gotten rid of the money, the situation can't be very alarming. Including engineers, firemen and cabin servants, you can't have over thirty-five or forty men in the crew, all told. There are nine of us in the cabin, and Haskell and the Americans will all stand with us. If we get together and put up a good front——"

Van Dyck interrupted hastily—over-hastily, I thought, for a man of his inches and determination in other fields.

"It is not to be thought of, Dick; not for a single moment, with all these women aboard. Besides, we have no arms. We'd be shot down in cold blood if it should come to blows."

This was so singularly unlike the Bonteck Van Dyck I had known best in the college days that it fairly made me gasp.

"Why, Bonteck!" I exclaimed; "what has come over you? You don't mean to say that you would calmly hand the yacht over to those fellows if they should ask you for it?"

"It might easily be the only thing to do," he asserted, half mechanically. "Of course, as I say, we haven't the money, and they would have their trouble for their pains, after all. Still, it might be difficult to convince them that the gol—the money has been actually disposed of. If they learned in New York that we really took it on board, and didn't learn afterward that it was disembarked elsewhere ... well, you see how it stacks up, don't you?"

"I see that you are making mountains out of molehills," I retorted. "What does Goff say about this potential mutiny?"

Van Dyck shook his head as if the mention of Goff merely added to the difficulties of the situation.

"That is another thing: Goff may be in it himself. He is an awful tough-looking old pirate. Don't you think so?"

"What I think is that you must have been completely off your head when you changed from your Atlantic-liner master and crew to this old fisherman and his Portuguese."

"Er—somebody recommended him; I forget just who it was," he went on to explain. "I needed a sailing-master who knew the Caribbean well, and who would do what he was told to do and ask no questions. You see the—er—shipping of the quarter million made some difference, and I couldn't afford to have too much intelligence aboard."

Again there was a pause, during which I was trying to persuade myself that this half-hearted young man across the stateroom table from me was really the same Bonteck Van Dyck who had coached crews, captained the 'Varsity football, and had otherwise proved himself a man and a leader of men—the sort of leader who fights to the final gasp, and even then doesn't know when he is beaten. The inability to do it put a little unconscious scorn into my summing-up of the situation.

"It is up to you, of course," I said. "We are merely your guests, and what you say is what we shall do. At the same time, I think—in fact I know—that you could count upon practically every man in our much-mixed passenger list to help you put down a mutiny."

"That is it—that is just why I sent for you, Dick," he cut in eagerly. "I knew you would be all for making a fight, and that you would probably lead it. For the sake of the women there mustn't be any scrap, you know. It would scare them into hysterics, naturally. If it should come to a showdown we must just make up our minds to take it easy—take the line of the least resistance—if you get what I mean. At the very worst, the mutineers couldn't well do more than to put us ashore somewhere, so that they might have a chance to search the yacht for the money. I have had that in mind all along, and when you came in just now I was trying to figure out our present latitude and longitude. Have you any idea where we are?"

"Trying to figure out?" I echoed. "Do you mean to tell me calmly that you—a navigator yourself and the owner of this ship—don't know where we are?"

"I'm ashamed to admit that I don't know—precisely. Goff keeps the reckoning, you see, and I have thought that perhaps he wasn't giving me the correct figures."

If any additional evidence had been needed, here was another and still more startling proof of the devastating change which had somehow been wrought in the Bonteck Van Dyck I had been thinking I knew. One of his hobbies in the past had been the study of practical navigation, and on more than one long cruise he had been his own sailing-master. That he should deliberately turn the Andromeda over to a man who had been merely "recommended" by some one whose name was already forgotten was little short of astounding.

"I truly hope there is nothing worse than an ordinary, every-day mutiny in store for us," I said grimly. "Judging from our course—which Goff may have changed every night, for all you seem to know—we ought to be somewhere in the southern half of the Caribbean. The steamer lanes are well charted, but there are a good many cays and islands outside of them—places where the bones of the Andromeda might lie until they rotted before anybody would ever discover them."

"And not all of the islands are inhabited, I take it," said Van Dyck, peering down at his chart as if he hoped to identify some of them.

"You know that as well as I do—or better," I snapped. And then: "What in the name of common sense has turned you into such a milk-blooded shuffler, Bonteck? You talk and act as if you weren't more than half——"

"Listen!" he said hastily, holding up a warning finger.

The stringy tinkle of Billy Grisdale's mandolin had stopped, and with it the singing. Above the murmuring diapason of the yacht's engines we both heard Edie Van Tromp's shrill cry of "Land-o-o-o!" As if the cry had been a pre-concerted signal, it was followed instantly by a confused trampling of feet on the deck over our heads, a sudden slackening of the yacht's speed, and more cries and foot-tramplings.

I was upon my feet and was reaching for the door-knob when Mrs. Van Tromp's throaty scream came from the adjoining saloon where the bridge players were sitting. Before I could turn the knob the door was thrust open, and the under-steward, whose ship name was Lequat, backed by two evil-faced fore-deck men armed with rifles, stood in the doorway. At the appearance of this warlike demonstration I was glad to see that Van Dyck, for once in a way, seemed genuinely shocked.

"You?" he demanded. "How is this? Where is Mr. Goff?"

The little man's smile and bow were like those of a dancing master.

"Ze captaine is sand me to inform you zat you are both ze prisonaire, oui. You vill sit down in ze chair and wait patient', M'sieu' Van Dyck—and you, Mistaire Preb'. Zis ees w'at you call all cut-and-dry, and——"

I suppose I sprang at his throat; it was the only thing for a live man to do. But the little beggar was quicker than a cat, and he brought me up all standing, with a huge pistol thrust into my face.

"Aha! you vill choke me, ees it? By gar, Mistaire Preb', eet is possib' I make you—how you say it?—walk ze board—ze plank, yes? You vill sit down on ze chair and tek eet easy. Ze sheep ees belong to h-us, and your fran's 'ave all been lock' up in ze staterooms. You can do notting; moi, Alphonse Lequat, vill tek ze comman'."

It was not until after all of this had happened that Van Dyck found his voice.

"Is this—is this a mutiny, Lequat?" he asked, as mild as mush.

"Eet is vat you vill be please' to call heem, M'sieu' Van Dyck, certainement. For fifteen, twanty, feefty minute' you vill sit on ze chair, and Pedro, he is stay outside ze door and keel you eef you make noises. Bam-by, moi, Alphonse Lequat, s'all come back to tell you vat eet is you s'all do." And then to his men: "Allons, mes garÇons!"

And with that he backed out of the owner's private cabin, and shut and locked the door.
