A white-winged bird floated over our heads and drifted away skywards.

She followed it with her eyes.

"You wonder at seeing me so early," she murmured. "Don't you think that it is worth while? Nothing ever seems so sweet as this first morning breeze."

I bowed gravely. She was standing bareheaded now at the edge of the cliff, watching the flight of the bird. It was delightful to see the faint pink come back to her cheeks with the sting of the salt wind.

Nevertheless, I had an idea in my mind that it was not wholly for her health's sake that Lady Angela walked abroad so early.

"Tell me," she said presently, "have you had a visitor this morning?"

"What, at this hour?" I exclaimed.

"There are other early risers besides you and me," she said. "The spinney gate was open, so some one has pa.s.sed through."

I shook my head.

"I have not seen or heard a soul," I told her. "I have just finished some work, and I am on my way up to the house with it."

"You really mean it?" she persisted.

"Of course I do," I answered her. "Grooton is the only person I have spoken to for at least nine hours. Why do you ask?"

She hesitated.

"My window looks this way," she said, "and I fancied that I saw some one cross the Park while I was dressing. The spinney gate was certainly open."

"Then I fancy that it has been open all night," I declared, "for to the best of my belief no one has pa.s.sed through it save yourself. May I walk with you back to the house, Lady Angela? There is something which I should very much like to ask you."

She replaced her hat, which she had been carrying in her hand. I stood watching her deft white fingers flashing amongst the thick silky coils of her hair. The extreme slimness of her figure seemed accentuated by her backward poise. Yet perhaps I had never before properly appreciated its perfect gracefulness.

"I was going farther along the cliffs," she said, "but I will walk some of the way back with you. One minute."

She stood on the extreme edge, and, shading her eyes with her hand, she looked up and down the broad expanse of sand--a great untenanted wilderness. I wondered for whom or what she was looking, but I asked no question. In a few moments she rejoined me, and we turned inland.

"Well," she said, "what is it that you wish to say?"

"Lady Angela," I began, "a few weeks ago there was no one whose prospects were less hopeful than mine. Thanks to your father and Colonel Ray all that is changed. To-day I have a position I am proud of, and important work. Yet I cannot help always remembering this: I am holding a post which you warned me against accepting."

"Well?"

"I am very curious," I said. "I have never understood your warning. I believe that you were in earnest. Was it that you believed me incapable or untrustworthy, or--"

"You appear to me," she murmured, "to be rather a curious person."

I bent forward and looked into her face. There was in her wonderful eyes a glint of laughter which became her well. She walked with slow graceful ease, her hands behind her, her head almost on a level with my own. I found myself studying her with a new pleasure. Then our eyes met, and I looked away, momentarily confused. Was it my fancy, or was there a certain measure of rebuke in her cool surprise, a faint indication of her desire that I should remember that she was the Lady Angela Harberly, and I her father's secretary? I bit my lip. She should not catch me offending again, I determined.

"You must forgive me," I said stiffly, "but your warning seemed a little singular. If you do not choose to gratify my curiosity, it is of no consequence."

"Since you disregarded it," she remarked, lifting her dress from the dew-laden gra.s.s on to which we had emerged, "it does not matter, does it? Only you are very young, and you know little of the world. Lord Ronald was your predecessor, and he is in a lunatic asylum. No one knows what lies behind certain unfortunate things which have happened during the last months. There is a mystery which is as yet unsolved."

I smiled.

"In your heart you are thinking," I said, "that such an unsophisticated person as myself will be an easy prey to whatever snares may be laid for me. Is it not so?"

She looked at me with uplifted eyebrows.

"Others of more experience have been worsted," she remarked calmly.

"Why not you?"

"If that is a serious question," I said, "I will answer it. Perhaps my very inexperience will be my best friend."

"Yes?"

"Those before me," I continued, "have thought that they knew whom to trust. I, knowing no one, shall trust no one."

"Not even me?" she asked, half turning her head towards me.

"Not even you," I answered firmly.

A man's figure suddenly appeared on the left. I looked at him puzzled, wondering whence he had come.

"Here is your good friend, Colonel Mostyn Ray," she remarked, with a note of banter in her tone. "What about him?"

"Not even Colonel Mostyn Ray," I answered. "The notes which I take with me from each meeting are to be read over from my elaboration at the next. n.o.body is permitted to hold a pen or to make a note whilst they are being read. Afterwards I have your father's promise that not even he will ask for even a cursory glance at them. I deliver them sealed to Lord Chelsford."

Ray came up to us. His dark eyebrows were drawn close together, and I noticed that his boots were clogged with sand. He had the appearance of a man who had been walking far and fast.

"You keep up your good habits, Lady Angela," he said, raising his cap.

"It is my only good one, so I am loth to let it go," she answered. "If you were as gallant as you appear to be energetic," she added, glancing at his boots, "you would have stopped when I called after you, and taken me for a walk."

His eyes shot dark lightnings at her.

"I did not hear you call," he said.

"You had the appearance of a man who intended to, hear nothing and see nothing," she remarked coolly. "Never mind! There will be no breakfast for an hour yet. You shall take me on to Braster Hill. Come!"

They left me at a turn in the path. I saw their heads close together in earnest conversation. I went on towards the house.

I entered by the back, and made my way across the great hall, which was still invaded by domestics with brushes and brooms. Taking a small key from my watch-chain, I unfastened the door of a room almost behind the staircase, and pushed it open. The curtains were drawn, and the room itself, therefore, almost in darkness. I carefully locked myself in, and turned up the electric light.

The apartment was a small one, and contained only a few pieces of heavy antique furniture. Behind the curtains were iron shutters. In one corner was a strong safe. I walked to it, and for the first time I permitted myself to think of the combination word. Slowly I fitted it together, and the great door swung open.

There were several padlocked dispatch-boxes, and, on a shelf above, a bundle of folded papers. I took this bundle carefully out and laid it on the table before me. I was on the point of undoing the red tape with which it was tied, when my fingers became suddenly rigid. I stared at the packet with wide-open eyes. I felt my breath come short and my brain reeling. The papers were there sure enough, but it was not at them that I was looking. It was the double knot in the pink tape which fascinated me.
