"Yes. It was I who told him to look after Dane. I know much about this matter." Then seeing Giles puzzled, she explained, "When I first met Anne I saw that she was like myself in looks. That drew us together. You see it yourself, do you not, Mr. Ware?"

"Yes," replied Giles, "and I often wondered at it. Now, however, that I know you are half-sisters, I wonder no longer."

Princess Karacsay nodded her approval, and Olga continued.

"When I learned that Anne's name was Denham I rather drew back from her.

She said that she was born in Jamaica, and, knowing what my mother had said about Denham, I thought Anne was the daughter of my mother's enemy.

Afterwards I learned the truth through Dane."

"How did you meet Dane?"

"Well, I knew him by sight long before we spoke. He used to dog Anne and myself. She never saw him. When I described his looks she thought he might be her dead father's secretary--for she then believed her father, Denham, alias Franklin, was dead. She wished to see him, but Dane always kept out of her sight. Then when Anne went to Mrs. Morley he still continued to dog me. He got to know a concert hall where I frequently sang and hired himself there as an attendant. Then he took to sending me love-letters. I was angry at first. Afterwards I wondered if he knew anything about Denham, and thought he must if he really was the secretary, as Anne said. I asked him to come here."

"Olga," said the Princess, "you have behaved badly."

"It has all turned out for the best," responded Olga wearily. She was beginning to show signs of fatigue again, but still kept on with her explanation in the most plucky manner. "Dane came. He is a handsome young fellow and was well dressed. I led him on to talk about Anne. He told me more than he should have done."

"Told you what?"

"That Denham had come in for money and was living at Rickwell. As I knew from Anne about the Powell money, I put two and two together and concluded that Denham was pretending to be Anne's father; that she was really my half-sister; and that her pretended father had really murdered Daisy Kent to get the money as Franklin."

"But how did you know about this?" asked Giles.

"Why," replied Olga, much surprised at his density, "I read the case in the papers. I knew that Anne could not have killed Daisy, and having settled in my own mind that she was not Denham's daughter, from her resemblance to me, I decided that Franklin, who lived at the Priory and had the money, was really my mother's enemy. I sent for my mother. She came over, went down to Rickwell, and recognized Denham. That is all."

"Wait a minute," said Giles quickly, "what about your telling Steel to look after Dane?"

"Well, Mr. Ware, it was this way," she answered. "When you came to me and talked about the Scarlet Cross, I remembered that Dane had such a one on his watch-chain."

"The badge of the gang!"

"Of course, but I did not know that until later. Then Steel came in, if you remember, and hinted that the red cross was the symbol of such a gang. Your talk of the cross being found in the church, and that you thought it was dropped by the criminal set me thinking. I sent for Dane again and tried to find out the truth. At first he refused, saying it was as much as his life was worth to talk."

"And I daresay he is right, mademoiselle. Denham would not stick at a second murder. By the way, did you know he was Wilson?"

"Only when Dane confessed. I gradually got him to be confidential to me, promising that he would not get into trouble. He was so deeply in love with me that he spoke out at last."

"My dear Olga!"

"Well, mother, I knew if I could get at the truth I could save Anne."

The Princess nodded, well pleased. "I am glad you thought of your sister." Olga flushed a deep red and her eyes sought those of Giles. "It was not my sister I thought of, but of myself," she said in a low tone.

"You see, mother, I fancied that I might get something if I could prove the innocence of Anne, for I----"

"Is any explanation needed, mademoiselle?" said Giles uneasily.

She paused for a moment and looked at him straightly. "No," she said at length; "that is all over. I think no more explanation need be made. But with regard to Dane. He told me that Denham had come to England to see about the money left to Daisy Kent. He disguised himself as Wilson and lodged at a Mrs. Benker's. Then he went down to Rickwell, and----"

"And murdered Daisy," interposed Giles eagerly.

"So I said, Mr. Ware; but Dane, who seems devoted in a way to Denham, denies that he struck the blow."

"Does he know who did?"

"No. He says Denham doesn't know either."

"Denham's a bigger scoundrel than you think," said Giles, recalling his last conversation at the Priory. "He accuses Anne of murdering the girl."

"He'll have to prove it, then," said Olga coolly, while her mother shrieked. "I'll be able to save Anne, never fear. However, Dane told me that the red cross was the badge of a thieves' gang. Denham had a yacht called _The Red Cross_, which goes from one port to another to take stolen goods on board."

"That's what Steel says."

"Of course. Dane told him when he taxed him with it. The boy, for he is just twenty-five, told me everything."

"And you told Steel," said Ware, rather reproachfully.

"I had to tell Steel, if I wished to save Anne," retorted Olga; "but I asked him to do nothing to imperil the liberty of Mark Dane."

"Did he promise that?"

"Yes. Dane saw him in Bournemouth. I told him to call with a note, which I gave him. Dane did not know why he was sent, and when he discovered that Steel was a detective, he became afraid. I believe he told something, but he afterwards ran away."

"He doesn't trust you any longer perhaps," said the Princess.

"From his att.i.tude last night I think he does, although he was a trifle reproachful. He will come if Steel has written a letter to call him here in my name. Then I daresay he will be able to explain why he took Anne away."

"Will he do so?"

"Ah! that is what we must find out." Olga paused, then continued. "I wanted Steel to learn all he could from Dane about Denham, as I wish to see that man arrested."

"Nothing would give me greater pleasure," cried the Princess.

"I thought of that. Denham tried to ruin your mother."

"And he did--he did!" she said bitterly.

"He tried, or rather he is trying, to ruin Anne also," said Olga. "For these reasons I wish Steel to find evidence against him, so that he may be arrested and made to confess his wickedness. Dane is the one who can tell most about him, and I think Dane will, for since Denham got the Powell money he had not behaved very well."

While they were thus talking a knock came to the door. The servant entered with a card, which she presented on a salver to her mistress.

Olga, who was thoroughly worn out, took it languidly, then suddenly became excited. "He is here!" she said. "Mark Dane is here!"
