When the darkness came on, and just as the moon was rising, Lister and Bella proceeded to the bridge of the boundary channel. Before leaving Cyril on that afternoon, Durgo had intimated that he wished Miss Huxham to meet him at that hour and at that place, and of course Cyril came also. He had every trust in the negro, who had proved himself in every way to be a man of worth. All the same, he did not intend to let Durgo meet Bella without being present. The black man was far too intimate with unseen forces, to please the white man, and it was necessary to protect Bella, if necessary.  
"He might put you into a hypnotic trance," explained Cyril, who had described all that had taken place.
 
"I should not let him do that," said the girl decidedly.
 
Cyril his shoulders. "Durgo might not care if you liked it or not. He would hypnotize you, if he wished."
 
"No, Cyril, he could not do that unless I consented. My will is my own, and it is a strong one. I suppose," said Bella, after a pause, "that he made Granny feel those aches and pains by controlling her mind."
 
Lister glanced sideways at her in surprise. "You seem to know all about it," he declared. "Where did you learn those terms?"
 
"At my school at Hampstead there was a girl who could hypnotise people. She read all manner of books about hypnotism, and talked about the subjective mind, although I don't know what it is. I can understand so much of Durgo's power over Granny. But that sending her spirit to the is strange. I don't believe that he did."
 
"He must have done so," insisted Cyril, "as Durgo did not know that the Vands were leaving, and Granny distinctly stated that they were, in my hearing. Also, if we find that the jewels are in the small portmanteau, marked with the initials M. F., we can be certain that her spirit really did travel."
 
"'M. F.,'" repeated Bella, dreamily: "those are my father's initials."
 
"Maxwell Faith. So they are. Humph! There is something in this business after all, Bella."
 
"But do you really think anyone can separate the spirit from the body?"
 
Lister reflected. "I don't see why not. After all, as St. Paul says, we are composed of spirit, soul and body, so in certain cases the one may become detached from the other. I remember"—he looked thoughtfully up to the cloudy sky—"I remember reading in some magazine of a boat-load of people being saved, owing to one of them transferring his spirit to a passing ship, and leaving written instructions in the cabin where the ship was to to."
 
"Oh, Cyril, that's impossible."
 
"My dear," he said drily, "you can see the log of that very ship, containing an account of the incident, at Somerset House. However, we have no time to discuss these matters further. Yonder is Durgo by the bridge. I want to know why he asked you to meet him here. Such a night, too"—Cyril shivered—"quite a change. I feel cold."
 
"So do I. It will rain, Cyril. Look at that heavy bank of clouds behind which the moon is hiding. And oh, how dark it is!"
 
It certainly was dark, and the two came very near Durgo before they saw him. The sky was heavy with gloomy clouds, and there promised to be rain before midnight. Durgo, wrapped in a heavy military cloak, stood sentinel by the plank bridge. When the lovers came up he led them across to the other side, and when they stood on Bleacres he used his great strength to rip up a couple of .
 
"There!" said the negro, flinging these into the corn, "they will not be able to get their boxes across, even if they can cross themselves."
 
"Are you talking of the Vands?" asked Bella quickly.
 
"Yes; they are still at the Manor-house. Look!"
 
He through the gloom, and they saw two or three windows of the old house lighted up brilliantly. Across other windows occasionally flitted more lights. Mrs. Vand was anxiously trying to impress the neighbours at least, such as might be abroad on this night—that she and her husband were ostentatiously at home. Durgo laughed grimly.
 
"They have quite an eye for dramatic effect," he said in his guttural voice, and very contemptuously. "Well, they shall have all the drama they want to-night, and more."
 
"Durgo," Bella in an alarmed tone, "you won't hurt them?"
 
"Not if I can help it."
 
Cyril interposed imperiously. "I shall not be a party to the breaking of the law," he said with sharpness, "nor will I allow Bella to——"
 
"Cyril Lister," interrupted the negro, turning on him and addressing him by his full name, as was his odd way; "if I could bring the police on the scene I would do so. But you know, as I do, that we have no proofs save those of the unseen, which would not be accepted in a court of law, to prove that the two are guilty of murder—of a double murder for all I know."
 
"A double murder!" echoed Bella, drawing closer to her lover.
 
"Yes. Edwin Lister, my master, has disappeared, and Huxham is dead. The old sailor, certainly, may have killed my master, but on the other hand, as I believe, Vand murdered Huxham, and probably murdered Edwin Lister also. Howsoever this may be, we can prove neither murder, so it is not advisable to bring the police into the matter.
 
"It would be safer," said Cyril uneasily. He feared lest Durgo's barbaric instincts should be aroused against the couple at the Manor-house.
 
"It would not be safer," retorted the negro. "While the police were debating and searching, the Vands would be getting out of the kingdom, and we could not stop them. Besides, they have the jewels. I am certain of that from what Granny Tunks saw when I loosened her spirit. Once the Vands got news of the police being on their track they would hide those jewels, and we should never find them. I want those jewels for you, Miss Huxham, as, before I leave England, I wish to see you happily married to Cyril Lister here. It is the least that I can do for his father's son."
 
"But if my father is alive and has the jewels?" asked Cyril doubtfully.
 
"That will make a difference," Durgo, "although I daresay that Edwin Lister will not mind returning the jewels. We can arrange our funds for the expedition in another way. But I fear," he added in gloomy tones, "that my master is dead. If so, I can only him."
 
"But with your occult powers, can't you learn if my father is dead or alive?"
 
"No," said Durgo very decidedly. "You forget that on the side of the unseen are powers who have to be obeyed. I can do much, but not all, and for some reason I am not permitted to know the truth about my master. Sooner or later I shall understand about this. What we have to do at the present time is to prevent the Vands from escaping. Will you both help?"
 
"Yes," said Bella, anticipating Cyril; "that is if you don't intend violence."
 
"Be comforted," said Durgo ironically; "be comforted, missy. I have no wish to put a rope round my neck. I simply mean to force these devils to give up the jewels, and to solve so much of this mystery as they know. When I the jewels and know what has become of my master, I shall let them go, or if you like I shall hand them over to the police. But time presses," added Durgo impatiently, "and at any time the two may come along on their way to freedom. Will you help?"
 
"Yes," said Cyril simply. "What do you want us to do?"
 
"Missy"—Durgo turned to the girl—"can you work that search-light?"
 
Bella nodded. "For an evening's amusement my father—I mean Captain Huxham—once showed me how to manipulate it."
 
"Well it is in good order, as we know that Vand used it last night. You can get into the house by the secret passage and watch for the going out of our two friends. Then turn on the search-light and use it as a pointer."
 
"I can use the search-light, and I daresay it is in order since Henry Vand used it last night," said Bella quickly; "also I can get to the upper part of the house and on to the roof, through a kind of well which runs from the lower to the higher secret passage. But what do you mean by my using the light as a pointer?"
 
"Direct the ray on to Vand and his wife; they may come down this path, or they may try and escape in another way. But if you bend the ray of the search-light to where they are, I'll be able to catch them. Use the ray as a finger, as it were."
 
Bella nodded. "I see, and where will you be?"
 
"I shall hide in the corn somewhere or another," explained Durgo. "I don't know where, as I can't be sure how Vand and his wife intend to escape."
 
"They may take the boat," suggested Cyril, "and that is tied up some distance yonder. I believe they will use the boat."
 
"No;" said Durgo shaking his head; "there is no place where they can row to, as this channel ends in swamps. All I can do is to walk here and there, and watch for the finger of the search-light."
 
"What am I to do?" asked Cyril anxiously; "go with Bella?"
 
"No you wait in Mrs. Tunk's hut. I daresay she is alone, as I asked her to send her grandson away to his gipsy before I came. I shall walk down with you, while Miss Huxham goes to the Manor-house."
 
"I would rather go with Bella," objected the young man uneasily.
 
"I am quite safe," said Bella , "and if you came, Cyril, there would be no room for us both in that narrow secret passage. I shall go by myself. Have no fear for me, dearest."
 
"One moment," said Durgo, as she was moving away. "Since you think that I may use violence, I may tell you, to quieten your minds, that the police are coming, after all."
 
"When did you tell the police to come? I thought you said——"
 
"Yes, yes!" interrupted the negro impatiently. "I know what I said. But I saw Inglis the other day when I went to Pierside, and informed him of my suspicions. I wired him to-day asking him to be with three or four men on the bank of the boundary channel opposite to Granny Tunks' hut."
 
"At what time?"
 
"About eleven, as I don't suppose that the Vands will try and escape until everyone in Marshely is asleep."
 
"Did you tell Inglis about the jewels?" as............
