"Not at all. I am merely going to ask you to return at nightfall to a.s.sist me in this minor investigation."

"If you ask my opinion," said the Inspector, "no further evidence is needed."

"I don't agree with you," replied Harley, quietly. "Whatever your own ideas upon the subject may be, I, personally, have not yet discovered one single piece of convincing evidence for the prosecution of Camber."

"What!" exclaimed Aylesbury, and even Detective-Inspector Wess.e.x stared at the speaker incredulously.

"My dear Inspector Aylesbury," concluded Harley, "when you have witnessed the experiment which I propose to make this evening you will realize, as I have already realized that we are faced by a tremendous task."

"What tremendous task?"

"The task of discovering who shot Colonel Menendez."

CHAPTER x.x.xI

YSOLA CAMBER'S CONFESSION

Paul Harley, with Wess.e.x and Inspector Aylesbury, presently set out for Market Hilton, where Colin Camber and Ah Tsong were detained and where the body of Colonel Menendez had been conveyed for the purpose of the post-mortem. I had volunteered to remain at Cray's Folly, my motive being not wholly an unselfish one.

"Refer reporters to me, Mr. Knox," said Inspector Wess.e.x. "Don't let them trouble the ladies. And tell them as little as possible, yourself."

The drone of the engine having died away down the avenue, I presently found myself alone, but as I crossed the hall in the direction of the library, intending to walk out upon the southern lawns, I saw Val Beverley coming toward me from Madame de Stamer's room.

She remained rather pale, but smiled at me courageously.

"Have they all gone, Mr. Knox?" she asked. "I have really been hiding.

I suppose you knew?"

"I suspected it," I said, smiling. "Yes, they are all gone. How is Madame de Stamer, now?"

"She is quite calm. Curiously, almost uncannily calm. She is writing. Tell me, please, what does Mr. Harley think of Inspector Aylesbury's preposterous ideas?"

"He thinks he is a fool," I replied, hotly, "as I do."

"But whatever will happen if he persists in dragging me into this horrible case?"

"He will not drag you into it," I said, quietly. "He has been superseded by a cleverer man, and the case is practically under Harley's direction now."

"Thank Heaven for that," she murmured. "I wonder--" She looked at me hesitatingly.

"Yes?" I prompted.

"I have been thinking about poor Mrs. Camber all alone in that gloomy house, and wondering--"

"Perhaps I know. You are going to visit her?"

Val Beverley nodded, watching me.

"Can you leave Madame de Stamer with safety?"

"Oh, yes, I think so. Nita can attend to her."

"And may I accompany you, Miss Beverley? For more reasons than one, I, too, should like to call upon Mrs. Camber."

"We might try," she said, hesitatingly. "I really only wanted to be kind. You won't begin to cross-examine her, will you?"

"Certainly not," I answered; "although there are many things I should like her to tell us."

"Well, suppose we go," said the girl, "and let events take their own course."

As a result, I presently found myself, Val Beverley by my side, walking across the meadow path. With the unpleasant hush of Cray's Folly left behind, the day seemed to grow brighter. I thought that the skylarks had never sung more sweetly. Yet in this same instant of sheerly physical enjoyment I experienced a pang of remorse, remembering the tragic woman we had left behind, and the poor little sorrowful girl we were going to visit. My emotions were very mingled, then, and I retain no recollection of our conversation up to the time that we came to the Guest House.

We were admitted by a really charming old lady, who informed us that her name was Mrs. Powis and that she was but an hour returned from London, whither she had been summoned by telegram.

She showed us into a quaint, small drawing room which owed its atmosphere quite clearly to Mrs. Camber, for whereas the study was indescribably untidy, this was a model of neatness without being formal or unhomely. Here, in a few moments, Mrs. Camber joined us, an appealing little figure of wistful, almost elfin, beauty. I was surprised and delighted to find that an instant bond of sympathy sprang up between the two girls. I diplomatically left them together for a while, going into Camber's room to smoke my pipe. And when I returned:

"Oh, Mr. Knox," said Val Beverley, "Mrs. Camber has something to tell you which she thinks you ought to know."

"Concerning Colonel Menendez?" I asked, eagerly.

Mrs. Camber nodded her golden head.

"Yes," she replied, but glancing at Val Beverley as if to gather confidence. "The truth can never hurt Colin. He has nothing to conceal. May I tell you?"

"I am all anxiety to hear," I a.s.sured her.

"Would you rather I went, Mrs. Camber?" asked Val Beverley.

Mrs. Camber reached across and took her hand.

"Please, no," she replied. "Stay here with me. I am afraid it is rather a long story."

"Never mind," I said. "It will be time well spent if it leads us any nearer to the truth."

"Yes?" she questioned, watching me anxiously, "you think so? I think so, too."

She became silent, sitting looking straight before her, the pupils of her blue eyes widely dilated. Then, at first in a queer, far-away voice, she began to speak again.

"I must tell you," she commenced "that before-my marriage, my name was Isabella de Valera."

I started.

"Ysola was my baby way of saying it, and so I came to be called Ysola. My father was manager of one of Senor Don Juan's estates, in a small island near the coast of Cuba. My mother"-she raised her little hands eloquently-"was half-caste. Do you know? And she and my father-"

She looked pleadingly at Val Beverley.

"I understand," whispered the latter with deep sympathy; "but you don't think it makes any difference, do you?"

"No?" said Mrs. Camber with a quaint little gesture. "To you, perhaps not, but there, where I was born, oh! so much. Well, then, my mother died when I was very little. Ah Tsong was her servant. There are many Chinese in the West Indies, you see, and I can just remember he carried me in to see her. Of course I didn't understand. My father quarrelled bitterly with the priests because they would not bury her in holy ground. I think he no longer believed afterward. I loved him very much. He was good to me; and I was a queen in that little island. All the negroes loved me, because of my mother, I think, who was partly descended from slaves, as they were. But I had not begun to understand how hard it was all going to be when my father sent me to a convent in Cuba.

"I hated to go, but while I was there I learned all about myself. I knew that I was outcast. It was"-she raised her hand-"not possible to stay. I was only fifteen when I came home, but all the same I was a woman. I was no more a child, and happy no longer. After a while, perhaps, when I forgot what I had suffered at the convent, I became less miserable. My father did all in his power to make me happy, and I was glad the work-people loved me. But I was very lonely. Ah Tsong understood."
