"I can keep you here till I have finished my campaign," Sartoris replied. "I could murder you, and n.o.body be any the wiser."

Berrington thought of Field, and smiled. Hitherto he had not tried diplomacy. His contempt and hatred for this man, his knowledge of his own strength and courage, had sufficed for the present. Now it seemed time to resort to strategy.

"You are quite correct, so far," he said. "I know much, I know a great deal more than you imagine. But in taking the risks I took to-night I did not do so blindly. I had my own reasons for attending to the work privately. But I recognized my danger and the man I had to deal with.

So, indeed, I would proceed to make my retreat safe. Did you ever hear of sealed orders?"

"Naturally I have. But what have they to do with the present case?"

"Everything. When an admiral detaches a part of his fleet in war time, he sends the detached part away with sealed orders which are to be opened under certain circ.u.mstances. If those said circ.u.mstances do not arise, then the sealed orders are destroyed. As I do not desire my second in command to know too much, I gave him sealed orders. If I do not return by a certain time, those orders are to be opened. I should say that they are being opened about now. You understand me?"

Sartoris nodded; it was quite clear that he understood perfectly well.

But his dry little face did not change in the slightest.

"That was clever," he said; "but not quite clever enough. I should have gone a little further if I had been in your position. What you say merely induces me to get rid of you altogether. But let us go into my room and discuss the matter quietly. Kindly turn my chair around, no, not that way. Grip the handle at the back and push me----"

Berrington heard no more. As his hands came in contact with the bra.s.s rail at the back of the chair there came a tremendous blow at the base of the brain, a cold feeling of sudden death, and the crisis was past.

When Berrington came to himself again he was lying on a bed in a small room; there was a lamp on a table by his side. He had no feeling whatever that he had suffered from violence of any kind, his head was clear and bright, his limbs felt as elastic and virile as ever. He was like a man who had suddenly awakened from a long sleep; he was just as fresh and vigorous. The bed on which he was lying completed the illusion.

"What new devil's work is this?" Berrington muttered. "Oh, I recollect."

The room was small but comfortably furnished. There was a fire ready laid in the grate; on the ceiling was a three-branch electrolier, but the switch by the door had been removed for some reason or other.

On the table by the bed was a very liberal supper, flanked by a decanter of whisky and a syphon of soda water, also a box of cigarettes and another of cigars. A silver match-box invited the prisoner to smoke. He took a cigarette.

Clearly he was a prisoner. The window was shuttered with iron, and a small round ventilator; high up, inside the door, was another sheet of iron. There was perhaps a little consolation in the fact that no personal violence was intended. For a long time Berrington reviewed the situation. At any rate he could see no way out of the mess for the present. He smoked his cigarette and ate his supper, and that being done, a feeling of fatigue stole over him. Looking at his watch, he saw that it was past one o'clock in the morning, a very late hour for him.

"I'll go to bed," Berrington told himself. "Perhaps I shall be able to see a way out in the morning. On the whole my diplomacy does not seem to have been a success. It would have been much better if I had not hinted that I had taken somebody else into my confidence."

Despite his danger Berrington slept soundly. Bright sunshine was pouring into the room through the little porthole in the iron shutter as he came to himself. By his side was a cold breakfast, with a spirit lamp for the purpose of making coffee. Berrington had hardly finished and applied a match to a cigarette before he was startled by the scream of a whistle.

Looking around to see whence the sound came, his eyes fell upon a speaking tube. His heart gave a great leap as it occurred to the prisoner that perhaps Mary Sartoris was calling him. He crossed over and pulled out the whistle at his end and answered promptly.

"Glad to hear that you have had a good night's rest," came the dry voice of Sartoris. "The bed is comfortable, the sheets well aired, and I can vouch for the quality of the cigars. By the way, as I have seen nothing of your confederate I am confirmed in my previous judgment that you were trying to bluff me. Is not that so?"

Berrington said nothing, silence giving consent. On the whole it occurred to him it would be far better to let Sartoris conclude that he was alone in the business.

"Very good," the dry voice went on; "you are like the curly-headed boy in the song who never--or hardly ever--told a lie. Now there is one little thing that I am going to ask you to do. And if you refuse I shall be under the painful necessity of causing you a great deal of physical suffering. On the table by the side of your bed you will find writing paper, pen and ink. You will be so good as to write a letter to Miss Beatrice Darryll or to Mrs. Richford--whatever you prefer to style her--asking her to call upon you at the address which is stamped on the head of the paper. You are to tell Miss Darryll that she is not to say anything to anybody about the visit--that she is to come at ten o'clock to-night or later. Tell her also that she is to bring the little bunch of keys that she will find in her father's dressing-case. You may take it from me that no harm whatever is intended to the young lady. When the letter is finished you will be so good as to push it under the door of your room."

"It is an excellent programme for you," Berrington said drily. "There is only one flaw in the little arrangement that I can see--I decline to do anything of the kind. You may do whatever you like and treat me in any way you please, but I shall decline to write that letter. And you may whistle up the tube all day, so far as I am concerned."

An oath came up the tube, then the voice of Sartoris, as if talking to somebody else. The whistle was clapped on, but almost immediately it was removed and another voice whispered the name of Berrington. His heart gave a great leap. Mary was speaking.

"For heaven's sake, write that letter," came the agonized whisper. "I pledge you my word----"

The voice stopped and the whistle was clapped into the tube again.

CHAPTER XXIII

The request was a strange one, Berrington thought.

Not that he failed to trust Mary Sartoris. In spite of everything, he had faith in her. Whatever she was doing in that queer household, no shadow of shame or disgrace could possibly lie on her.

And yet what could she want that letter for? Again, what was the need to drag Beatrice Darryll into this black business? The more Berrington thought it over, the more puzzled he became. Only one thing was tolerably clear--Sir Charles Darryll had valuable interests somewhere, interests of which he had been in utter ignorance, and which these ruffians had determined to obtain and apply to their own ends.

Still, Berrington hesitated. He did not know what would be for the best.

If he declined to write that letter it might be the worse for him and everybody else in the long run; if he did write the letter it might possibly prove harmful to Beatrice. Certainly Carl Sartoris had that end in view. Then there was another thing to take into consideration. Had Inspector Field got safely away?

Berrington could not be absolutely certain, for the reason that there had been no attempt to rescue him which was Field's obvious duty when he escaped. Yet a great many hours had pa.s.sed and there had been no attempt of the kind.

Very thoughtfully Berrington took paper and pen and ink from the drawer in the table. He was not surprised to see that the paper bore the address "100, Audley Place." So Beatrice was to be lured there for some reason, or other, and Berrington was to be used for the purpose. He threw the pen down and determined that he would do nothing in the matter. He had barely come to this conclusion when the whistle in the tube sounded very faintly. It might have been no more than the wind in the pipe, and yet on the other hand it might have been meant for a cautious message. Berrington crossed over and asked a question in a low voice. Immediately a reply came in the faintest possible whisper.

"It is I who speak," the voice said. "Mary, you know. By accident I have a chance of a few words with you again. My brother thinks that I am in ignorance of everything. He told me that you had left the house and that everybody had gone. At the same time he declined to have the servants back yet, and that aroused my suspicions. You can hear me?"

"My dearest girl, I can hear you perfectly well," Berrington replied.

"Where is your brother now? Can you speak freely to me for a time?"

"For a minute or two perhaps, certainly not more. Carl has gone into the conservatory for something; he may be back almost at once. He told me that you had gone. I did not believe it for a minute, so I watched and listened. Then I found out that you were a prisoner here; I found out all about the letter."

"The letter to Beatrice Darryll, you mean?"

"Yes, yes. Don't ask me why they desire to get her here, because I can't tell you,--I don't know. But there is something about Burmah and ruby mines that I fail to understand. It has something to do with Sir Charles Darryll and Miss Violet Decie's father."

"Shall we ever get to the bottom of this business!" Berrington exclaimed. "But why should you particularly want me to write that letter?"

"Because I shall be chosen as the messenger," the girl said eagerly.

"There are no servants here; the rest of my brother's friends are busy elsewhere. I gather that the letter is urgent; that being the case, I shall be chosen to take it. You see, I am supposed to know nothing whatever about it. I shall be able to see Miss Darryll myself."

Berrington expressed his appreciation of the suggestion. Perhaps Mary might find herself in a position to do more than that.

"Very well," he said. "Under the circ.u.mstances I am to write that letter with the understanding that you are going to convey it to its destination and warn Miss Darryll. But you must do more than that, Mary.

It is impossible that I can remain a prisoner here like this. The thing is a daring outrage in the middle of London; it sounds more like a page from a romance than anything else. At all risks, even to the brother by whom you are standing so n.o.bly, you must do this thing for me. After you have seen Miss Darryll you are to go down to Scotland Yard and ask for an interview with Inspector Field. Tell him where I am to be found and----"

"Oh, I cannot, Philip, dearest," came the trembling whisper. "My own brother----"

"Who has been the curse of your life and mine," Berrington said sternly.

"What do you suppose you gain by standing by him in this fashion? Sooner or later he must come within grip of the law, and so all your sufferings will be futile. If there was anything to gain by this self-sacrifice I would say nothing. But to spoil your life for a scoundrel like that----"

"Don't say it, Phil," Mary's voice pleaded. "Please don't say it. If you love me as you once seemed to do, have a little patience."

All the anger melted out of Berrington's heart. He had intended to be hard and stern, but that gentle, pleading voice softened him at once.

Knowing Mary as he did, he could imagine what her life had been these last three years. Her sense of duty was a mistaken one, perhaps, but it was n.o.bly carried out, all the same. Sooner or later the effort must be lost, and it occurred to Berrington that it would be cruel to hurry the end. Besides, there would be a greater satisfaction to him to feel that he had beaten Sartoris at his own game.

"I love you now as I loved you in the happy years gone by," he said.

"Indeed, I love you more, for I know how you have suffered, dearest.

Mind you, I am not afraid. I do not regard myself as being in any great danger here--that is not the point. So I will write the letter and you shall deliver it when you please. What is that?"
