On my little table lay the letter I expected, large, square, and white.

I tore it open with trembling fingers. The handwriting was firm and yet delicate. I knew at once whose it was.

"Rowchester, Tuesday.

"DEAR MR. DUCAINE,--My father wishes me to say that he and Lord Chelsford will call upon you to-morrow morning, between ten and eleven o'clock.--With best regards, I am,

"Yours sincerely,

"ANGELA HARBERLY."

The letter slipped from my hands on to the table. Lord Chelsford was a Cabinet Minister and a famous man. What could he have to do with any appointment which the Duke might offer me? I read the few words over and over again. The handwriting, the very faint perfume which seemed to steal out of the envelope, a moment's swift retrospective thought, and my fancy had conjured her into actual life. She was there in the room with me, slim and shadowy, with her quiet voice and movements, and with that haunting, doubtful look in her dark eyes. What had she meant by that curious warning? What was the knowledge or the fear which inspired it? If one could only understand!

I sat down in my chair and tried to read, but the effort was useless.

Directly opposite to me was that black uncurtained window. Every time I looked up it seemed to become once more the frame for a white evil face.

At last I could bear it no longer. I rose and left the house. I wandered capless across the marshes to where the wet seaweed lay strewn about, and the long waves came rolling sh.o.r.ewards; a wilderness now indeed of grey mists, of dark silent tongues of sea-water cleaving the land. There was no wind-no other sound than the steadfast monotonous lapping of the waves upon the sands. Along that road he had come; the faintly burning light upon my table showed where he had pressed his face against the window. Then he had wandered on, past the storm-bent tree at the turn of the road pointing landwards. A few yards farther was the creek from which we had dragged him. The events of the night struggled to reconstruct themselves in my mind, and I fought against their slow coalescence. I did not wish to remember--to believe. In my heart I felt that for some hidden reason Ray was my friend. This visit of the Duke's, with whatever it might portend, was without doubt inspired by him. And, on the other hand, there was the warning of Lady Angela, so earnestly expressed, so solemn, almost sad. How could I see light through all these things? How could I hope to understand?

The Duke came punctually, spruce and debonnair, a small rose in his b.u.t.tonhole, his wizened cheeks aglow with the smart of the stinging east wind. With him came Lord Chelsford, whose face and figure were familiar enough to me from the pages of the ill.u.s.trated papers. Dark, spare, and tall, he spoke seldom, but I felt all the while the merciless investigation of his searching eyes. The Duke, on the other hand, seemed to have thrown aside some part of his customary reserve. He spoke at greater length and with more freedom than I had heard him.

"You see, Mr. Ducaine," he began, "I am not a man who makes idle promises. I am here to offer you employment, if you are open to accept a post of some importance, and also, to be frank with you, of some danger."

"If I am qualified for the post, your Grace," I answered, "I shall be only too willing to do my best. But you must excuse me if I express exactly what is in my mind. I am almost a stranger to you. I am a complete stranger to Lord Chelsford. How can you rely upon my trustworthiness? You must have so many young men to choose from who are personally known to you. Why do you come to me?"

The Duke smiled grimly.

"In the first place," he said, "we are only strangers from the personal point of view, which is possibly an advantage. I have in my pocket a close record of your days since you entered the university. I know those who have been your friends, your tastes, how you have spent your time. Don't be foolish, young sir," he added sharply, as he saw the colour rise in my cheeks: "you will have a trust reposed in you such as few men have ever borne before. This prying into your life is from no motives of private curiosity. Wait until you hear the importance of the things which I am going to say to you." I was impressed into silence.

The Duke continued--"You have heard, my young friend," he said, "of the Committee of National Defence?" "I have read of it," I answered.

"Good! This committee has been formed and sanctioned by the War Office in consequence of the shocking revelations of inefficiency which came to light during the recent war. It occurred to the Prime Minister, as I dare say it did to most of the thinking men in the country, that if our unreadiness to take the offensive was so obvious, it was possible that our defensive precautions had also been neglected. A. board was therefore formed to act independently of all existing inst.i.tutions, and composed chiefly of military and naval men. The Commander-in-Chief, Lord Chelsford, Colonel Ray, and myself are amongst the members. Our mandate is to keep our attention solely fixed upon the defences of the country, to elaborate different schemes for repelling different methods of attack, and in short to make ourselves responsible to the country for the safety of the Empire. Every harbour on the south and east coast is supposed to be known to us, every yard of railway feeding the seaports from London, all the secret fortifications and places, south of London, capable of being held by inferior forces. The mobilization of troops to any one point has been gone thoroughly into, and every possible movement and combination of the fleet. These are only a few of the things which have become our care, but they are sufficient for the purpose of ill.u.s.tration. The importance of this Board must be apparent to you; also the importance of absolute secrecy as regards its doings and movements."

I was fascinated by the greatness of the subject. However, I answered him as quickly as possible, and emphatically.

"The Board," the Duke continued, "has been meeting in London. For the last few months we have had business of the utmost importance on hand.

But on January 10, that is just six weeks ago, we came to a full stop.

The Commander-in-Chief had no alternative but temporarily to dissolve the a.s.sembly. We found ourselves in a terrible and disastrous position.

Lord Ronald Matheson had been acting as secretary for us. We met always with locked doors, and the names of the twelve members of the Board are the most honoured in England. Yet twenty-four hours after our meetings a verbatim report of them, with full particulars of all our schemes, was in the hands of the French Secret Service."

"Good G.o.d!" I exclaimed, startled for the moment out of my respectful silence.

The Duke himself seemed affected by the revelation which he had made.

He sat forward in his chair with puckered brows and bent head. His voice, which had been growing lower and lower, had sunk almost to a whisper. It seemed to me that he made a sign to Lord Chelsford to continue. Almost for the first time the man who had done little since his entrance save watch me, spoke.

"My own political career, Mr. Ducaine," he said, "has been a long one, but I have never before found myself confronted with such a situation.

Even you can doubtless realize its effect. The whole good of our work is undone. If we cannot recommence, and with different results, I am afraid, as an Englishman, to say what may happen. War between England and France to-day would be like a great game of chess between two masters of equal strength--one having a secret knowledge of his opponent's each ensuing move. You can guess what the end of that would be. Our only hope is at once to reconstruct our plans. We are hard at it now by day and by night, but the time has arrived when we can go no further without a meeting, and the actual committal to paper and diagram of our new schemes. We have discussed the whole matter most carefully, and we have come to the following decision. We have reduced the number of the Board by half, those who have resigned, with certain exceptions, having done so by ballot. We have decided that instead of holding our meetings at the War Office they shall take place down here at the Duke's house, and so far as possible secretly. Then, as regards the secretaryship. No shadow of suspicion rests upon Lord Ronald any more than upon his predecessors, but, as you may have read in the newspapers, he has temporarily lost his reason owing to the shock, and has been obliged to go to a private home. We have decided to engage some one absolutely without political connexions, and whose detachment from political life must be complete. You have had a warm advocate in Colonel Mostyn Ray, and, subject to some stringent and absolute conditions, I may say that we have decided to offer you the post."

I looked from one to the other. I have no doubt that I looked as bewildered as I felt.

"I am a complete stranger to all of you," I murmured. "I am not deserving in any way of such a position."

Lord Chelsford smiled.

"You underrate yourself, young man," he said drily, "or your college professors have wandered from the truth. Still, your surprise is natural, I admit. I will explain a little further. Our choice is more limited than you might think. At least fifty names were proposed, all of them of young men of the highest character. Each one, however, had some possibly doubtful relative or a.s.sociation or custom in life. It is evident that there is treachery somewhere in the very highest quarters.

These young men were sure to be brought into contact with it. Now it was Ray's idea to seek for some one wholly outside the diplomatic world, living in a spot remote from London, with as few friends as possible, who would have no sentimental objections to the surveillance of detectives. You appear to us to be suitable."

"It is a wonderful offer!" I exclaimed.

"In a sense it is," Lord Chelsford continued. "The remuneration, of course, will be high, but the post itself may not be a permanency, and you will live all the time at high pressure. The Duke will place a small house at your disposal, and it will be required that you form no new acquaintances without reference to him, nor must you leave this place on any account without permission. You will virtually be a prisoner, and if certain of my suspicions are correct you may even find the post one of great physical danger. On the other hand, you will have a thousand a year salary, and a sum of five thousand pounds in two years' time if all is well."

Excitement seemed to have steadied my nerves. I forgot all the minor tragedies which had been real enough things to face only a few hours ago. I spoke calmly and decisively.

"I accept, Lord Chelsford," I said. "I shall count my life a small thing indeed against my fidelity."

He drummed idly with his forefinger upon the table. His eyes were wandering around the room absently. His face was calm and expressionless.

"Very well, then," he said, "my business here is settled. I shall leave it with the Duke to acquaint you with the practical details of your work, and our arrangement."

He rose to his feet. The Duke glanced at his watch.

"You have only just time for the train," he remarked. "The car shall take you there. I prefer to walk back, and I have something further to say to Mr. Ducaine."

Lord Chelsford took leave of me briefly, and the Duke, after accompanying him outside, returned to his former seat. I ventured upon an incoherent attempt to express my grat.i.tude, which he at once waved aside. He leaned over the table, and he fixed his eyes steadfastly upon me.

"I am able now," he said, "to ask you a question postponed from the other day. It is concerning the man who was found dead in the creek."

His merciless eyes noted my start.

"Ah!" he continued. "I can see that you know something. I have my suspicions about this man. You can now understand my interest when I hear of strangers in the neighbourhood. I do not believe that he was a derelict from the sea. Do you?"

"No," I answered.

He nodded.

"Am I right," he said, "in presuming that you know he was not?"

"I know that he was not," I admitted.

His fingers ceased their beating upon the table. His face became white and masklike.

"Go on," he said.

"I know that he came through Braster, and he asked for me. He looked in through the window of my cottage when Colonel Ray was with me. I saw him no more after that until I found him dead."

"Ray left you after you had seen this man's face at the window?"

"Yes."

"The wounds about the man's head and body. If he was not thrown up by the sea, can you explain them?"

"No," I answered with a shudder.
