“We must keep a sharp look-out upon them, Wyndham,” he said on the morning of the day after that on which they had resumed their voyage. “If it wasn’t that it would be impossible to navigate the ship without them, there’s hardly one of these fellows with whom I would like to sail. I shall send them adrift at Port Elizabeth, along with Bostock and Van Ryk and Sherwin. I expect there will be no lack of good hands there.”

“Well, it won’t be very long, sir,” said Wyndham, – “not above three or four days at the outside, and there are enough of us to put down any disturbance during that time. I’ll speak to Mr Rivers and Mr Whittaker, and the others. They’d be very useful if any disturbance occurs.”

“I will speak to Mr Whittaker myself,” said the captain. “He told me something yesterday, an hour or two after we left the harbour, which if he had mentioned before, I should have taken certain steps, which it would be too late to take now. I gave him my mind on the subject, though there was no great use in doing that.”

“What, he has something valuable on board, I suppose?” observed Wyndham; “I have suspected as much for a long time. That was why he would not go ashore at Saint Helena, then?”

“Yes,” said the captain; “I think under the circumstances it is quite as well you should know, Wyndham. He has got 5000 pounds in specie, which he is taking out to the bank at Maritzburg. Of course he was bound to tell me – to give it into my custody, in fact – before we sailed. He declares he did not know that. That may be true, though it seems strange he should be ignorant of it. But, any way, it is no use discussing that matter any further.”

“No, sir. I suppose you have it in your charge now?”

“Yes, of course. I have put it away in the strong cupboard, and will not deliver it up till we reach Durban.”

“And what made Mr Whittaker tell you about it this morning, more than on any other day?” asked Wyndham.

“That is one of the most unpleasant features in the matter,” rejoined the captain. “Mr Whittaker has always kept his cabin locked throughout the voyage, and has never been absent from it for any considerable time. Until this morning, he had no suspicion but what everything was perfectly safe. But last night, after the passengers had gone to bed, he fancied he heard a noise in the passage, and caught a glimpse of some one hurrying away. This morning, on going into his cabin, he found Bostock there; and on his inquiring what business the man had in his cabin, Bostock muttered something about having gone in to clean it out. But it is not Bostock’s business to clean the cabins. Mr Whittaker was alarmed, and came to me immediately afterwards.”

“Indeed, sir! That looks ugly, certainly. You must get rid of Bostock when we get to Port Elizabeth.”

“I have already said that I meant to do so. Indeed, I would have dismissed him at Cape Town, if Mr Whittaker had spoken to me in time. All that we can now do is to keep a bright look-out. Mr Whittaker and I are alternately to keep watch in my cabin, until we drop anchor in Algoa Bay. You had better keep an eye on Bostock; and it would be as well if you asked Mr Rivers to help you in doing so. Mr Rivers is, to my mind, as stout-hearted and cool-headed a fellow as any we have on board.”

“I agree with you in that, sir, and will see Mr Rivers at once. But I don’t apprehend much mischief from John Bostock. The man seems to me as if he had lost his head.”

If Mr Wyndham could have been present at a conversation which had taken place an hour or two before between Bostock, Van Ryk, Andersen, the captain’s servant, and a sailor named Sherwin, he would hardly have expressed this opinion. John Bostock, little as Wyndham suspected it, was by birth a gentleman. He was the son of a Lincolnshire squire of ancient family, but very reduced means. His father was the last of a long series of spendthrifts, who had gradually reduced a noble inheritance to a heap of encumbrances. Langley Cargill, or, as he now called himself, John Bostock, was one of his younger sons. He followed in his father’s steps, and was soon hopelessly involved in debt. He tried to live by successful betting and gambling, but failed here also, and was reduced to extreme straits, when a boon companion, a man of some influence, obtained for him a commission in a Dutch regiment quartered at the Hague. Here he was safe from creditors, and had an income upon which it would have been possible to live decently, if strict economy had been observed. But to Cargill economy had become impossible. He fell into his old courses, and would probably have soon been expelled from the Dutch service, if his ruin had not been precipitated by an outrage which drew on him the punishment of the law.

In the second year of his residence he was attracted by the grace and beauty of a young girl, who had just made her first appearance in public. Langley contrived to obtain an introduction, which he tried for several months to improve into an acquaintance. The lady’s friends, who were aware of his character, interfered to prevent this. Her brother, in particular, a haughty young officer, had forbidden all intercourse; and on the occasion of a public ball, when Cargill was more than usually importunate, had insisted on his leaving the room. Cargill replied by drawing his sword on Vander Heyden. The police interfered, and Cargill was insane enough to resist, wounding several men, and one severely. He would have received a heavy sentence, if he had not contrived to escape from prison, and enlist as a sailor in a ship just leaving the harbour. After several voyages he found himself in London, and in the autumn of 1879 engaged himself, under the name of Bostock, as an A.B. on board the Zulu Queen, about to sail for Durban. Here he found Jans Van Ryk, Amos Sherwin, and Eric Andersen, old companions of his coarse debauches. A day or two after leaving harbour, he also recognised Annchen Vander Heyden and her brother, as the reader has heard in the previous chapter. Annchen had no suspicion that she had even seen him before; but her brother’s memory was better, though with the scornful hauteur of his character he paid no further heed to Bostock’s presence.

It will readily be believed that Bostock was not so indifferent to their former relations. He had devised a scheme by which he was to revenge himself on Vander Heyden, during the ship’s stay at Cape Town. He had resolved to follow him on shore, force him to a personal encounter, in which, being himself a first-rate swordsman, he expected to get the better of his antagonist, and, in event of his wounding or killing him, make his escape to the Transvaal, which was at the time full of lawless characters. He had been baffled by Wyndham, who had refused him permission to leave the ship during the stay at Cape Town. Provoked to fury by this failure, he had resolved to enter Vander Heyden’s cabin on the night of his return to the Zulu Queen, kill him, or be killed; and, if he should prove the survivor, throw himself into the sea and swim ashore. His purpose was a second time defeated – in this instance by Mr Whittaker, who occupied the next cabin to Vander Heyden, and who, as Bostock could see through the glass in his door, was awake and completely dressed. Surprised as well as disconcerted, he looked through the square of glass, and saw Whittaker engaged in counting a number of packages, which he perceived to be rouleaus of gold. The strong iron-bound chest was evidently full of them; in which case, he must have a very large sum of money with him. This discovery turned his thoughts into a different channel. He took an opportunity the next day of visiting Mr Whittaker’s cabin, to make some examination of the chest, but was surprised by the sadden entrance of its owner. Mr Whittaker threatened to complain to the captain, and Bostock had no doubt he had carried out his threat. He felt at once that if he was to execute his designs either on Vander Heyden or the chest of specie, it must be done before the ship reached Algoa Bay. He had therefore invited his three mates in evil to a conference in the hold of the vessel. At this he imparted to them the discovery he had made, and the three worthies between them had hatched a plot, which was that very night to be put into execution.

When Wyndham left Captain Ranken, he went immediately to George Rivers’ cabin, to whom he imparted the information received from the captain. George at once agreed to do all that lay in his power, and promised to join the first mate on deck, after he had taken a few hours’ sleep. Wyndham, on his part, went to take his supper, which was brought him by Amos Sherwin, one of the quartermasters, his own servant, it appeared, being ill.

The night came on suddenly, as is usual in those latitudes, and the moon was obscured by clouds. About ten o’clock the first mate came on deck to take his watch. He complained of feeling drowsy and heavy; but was nevertheless quite able to take his work. A steady hand was placed at the wheel, and everything was quiet on deck. Walters and Margetts, who had not been disposed to turn in, were seated near the taffrail, smoking. Notwithstanding the darkness, the night was pleasant, and it was possible occasionally to discern the coast-line, – which was distant two or three miles, – though very indistinctly. The first mate seated himself near them, leaning his head on his hand. A few minutes afterwards, some one came up with a message to the steersman, and the latter, surrendering the wheel to the newcomer, went below. The night wore on, and after a while the moon, forcing its way through the clouds, lit up the scene. The two young men now noticed that the ship appeared to be a good deal nearer to the coast than it had been all day. Walters called out to the first mate to point out the fact to him. He hailed him once or twice, but received no answer.

“I say,” he exclaimed, “Wyndham must be asleep. Oughtn’t we to wake him, Redgy?”

“He can hardly be asleep,” returned Margetts, – “a smart hand such as he is. But I’ll go and speak to him.”

He stepped up to Mr Wyndham’s side, and, finding he still took no notice, shook him. But the mate did not bestir himself, and the two young men perceived that he was either seriously ill, or intoxicated.

“I say, this is serious,” said Redgy; “we had better go down and bring the captain, hadn’t we? Look here, if you’ll take charge of him, I’ll go to the skipper’s cabin.”

He hurried to the companion accordingly, and on his way encountered George Rivers, who was coming up, according to promise, to join the first mate. He hastily informed him of what was going on up above; and George, a good deal startled, hastened to the place where Wyndham was still sitting, with Walters leaning over him. But, while crossing the deck, he caught sight of an object which filled him with astonishment and alarm. This was the coast-line, which was now clearly visible in the broad moonlight.

“What can you be about?” he shouted to the man at the wheel. “We are more than half a mile nearer shore than we ought to be. If our course is not immediately changed, we shall run upon a reef; and, by Heaven!” he added, a moment afterwards, “there is a reef just ahead of us! Starboard hard! – starboard, I say! Are you drunk, or mad, that you don’t see where you are taking us?” he continued, as the man, paying no heed to his warnings, allowed the ship to drive on straight towards the reef.

George rushed up, and endeavoured to wrest the helm from his grasp; but it was too late. The next moment a grinding noise was heard, as the ship’s keel grated over a sunk rock. Then came a tremendous crash, which shook her from stem to stern, and the Zulu Queen was lodged hard and fast on the reef. George collared the steersman; but he was a powerful man, and shook off his assailant’s hold. Pulling his cap farther over his face, he ran down the hatchway, but not before Rivers had recognised Jans Van Ryk, a Dutch sailor, against whom Wyndham had warned him as one of Bostock’s intimate companions.

It was no use following the man. Indeed it would have been impossible to do so; for in another minute the hatchway was crowded with men, who rushed up, half-dressed and in deadly terror, to know what had happened.

“Where is Mr Wyndham?” shouted the captain. “How can he have allowed the ship to run on a rock after this fashion, in a light where everything is as clear as noonday?”

“Mr Wyndham is in a kind of fit, sir,” said Margetts. “He has been sitting there without moving for the last hour or two. You had better go to him yourself.”

The captain stepped across the deck, and took a look at the first mate’s face.

“Come here, McCarthy!” he cried to the surgeon. “He has been drugged, hasn’t he?”

The surgeon put his hand to Wyndham’s pulse, and, bending down, inhaled his breath.

“Yes, sir; he has been drugged with opium. This has been a preconcerted thing!”
