Olga looked at him with an inquiring air. "How much do you know?" she asked, bracing herself up.

"As much as your mother could tell me. I know that Anne is your half-sister, and----"

"Yes." Olga tried to rise, but sank back again. "She is my sister, my dear sister, and I love her with all the strength of my nature."

"Ah," said Ware sadly, "why did you not talk like that when last we met, mademoiselle?"

Olga pa.s.sed her hand across her forehead. "I was mad, I think. But that is all over. You need have no fear now, Mr. Ware. My pa.s.sion for you has spent itself."

"Olga!" cried the Princess, scandalized, "you rave!"

"No," answered her daughter; "I did last time Mr. Ware and I were together, but now I talk sense. Did he not tell?"

"I told nothing," interposed Giles quickly; "and you had better relate when and where you left Anne, so that we can find her."

"I'll do all in my power to save her and bring her back to you, Mr.

Ware. I was mad to talk and act as I did; but I have been punished by the loss of Anne."

"Olga!" cried the Princess in desperation, "for Heaven's sake speak reasonably! Why did you go out with Anne last night?"

"There was a note for Anne from Mark Dane, asking her to meet him near the Abbey. She wanted to see him, as he vanished after the supposed death of her father."

"Of Alfred Denham," interrupted the Princess angrily; "I will not have that man called Anne's father."

"Of Denham," said Olga obediently. "Anne wished to learn why her father had acted in so peculiar a way. She could not understand his behavior."

"He is a scoundrel and Anne a saint," said the Princess bitterly. "No wonder she could not understand him. She thinks he is a good man."

"But surely she knows that he killed Daisy Kent," said Giles.

"No," interposed Olga; "she denies that he did. I expect Denham has managed to deceive her in some way."

"Why did you not undeceive her, mademoiselle?"

"It was not yet time," responded the girl quietly, "but my mother told her a portion of the truth."

"Yes. I said that she was my child and that Denham had been impersonating her father, George Franklin."

"Then she can't think Denham a good man now," said Giles.

"I don't know," replied the Princess hopelessly. "He has such power over her. He has been her father so-called for so long that she finds it difficult to believe ill of him."

"To learn the truth was why she insisted on seeing Dane," said the girl.

"Dane knew all about Denham, and Anne thought she would make him confess what he knew."

"And did he?"

"That I can't say. I went out with Anne and we walked to the appointed spot. Mark Dane was waiting for us."

"Was he not astonished when he saw you?"

"Why should he be astonished?" asked Olga, looking sharply at Ware.

"Because I understand from Steel that he troubled you with letters."

"You mean that Dane was in love with me. Yes. He was and is."

"Olga," cried her mother again, "do behave yourself."

"Oh, this is too serious to be a mere matter of behavior, mother. I have made use of Dane's love to learn all about the society of the Scarlet Cross, to which Franklin and Dane belong."

"You can tell us that later," said the Princess impatiently. "I want to know how you lost Anne."

"Well, mother, Dane was astonished to see me. He was most respectful, and said that he had a message for Anne from her father----"

"From Denham."

"Yes. Anne mentioned that Denham was not her father, that she had just heard the truth, and Dane was amazed. He hardly knew what to say, but ultimately stammered out some sort of denial. Anne did not give him time to speak. She said that she would see Denham herself, and get to the bottom of the imposture. Then she asked what message he had sent in the character of her father. Dane refused to give it in my presence, so I walked away for ten minutes and left them together. Oh, I was foolish, I know," she added in reply to Ware's exclamation. "But I thought Mark Dane was devoted to me, and would not play any tricks while I was about.

However, I did leave them alone. Anne was not in the least afraid, as she always got on well with Dane and trusted him entirely. When I returned in ten minutes, or it may be more, they were gone."

"Gone!" echoed the Princess, much agitated. "Where?"

"I don't know. I searched everywhere. I went round and round the Abbey.

I asked a policeman. They were nowhere to be found. I fancied that they went across to Westminster Bridge, which they could easily do without my seeing them. Anne must have gone of her own accord. She was decoyed by Dane. I don't know why, no more than I know what inducement he held out to lure her away. I searched for hours. Then I asked a policeman about the matter. He told me to go to Scotland Yard. I went and inquired for Steel. He had gone home. I have been walking the streets all night,"

said Olga, with a haggard look.

"Oh, great heavens!" moaned the Princess, wringing her hands; "what would your father say if he heard?"

"He will never know unless you tell him, mother. I can look after myself easily. No one molested me. I had a cup of coffee at a stall this morning, and went again to see Steel. He has gone out of town."

"To Rickwell?" asked Giles eagerly; then he remembered. "I can't understand. I called to see Steel at midday before I came here, and he was then in his office."

"Well, the official I spoke to about nine o'clock told me that he had gone, leaving a message that he was going out of town, and would not be back for a few days."

"I wonder," began Giles, and then held his peace. It occurred to him that Steel intended to remain until he caught Dane in the trap laid for him in this very flat. The knowledge that the man had decoyed Anne away on the previous night made Giles the more eager that he should be caught. "You will see Anne yet, Princess," he said, for she was crying bitterly.

"Oh, I hope so--I hope so. But where is she?"

"We must ask Dane that."

"How are we to see Dane?" demanded Olga wonderingly.

Ware explained the use made of Olga's name by Steel to trap the man. "I expect Steel will call on you to-day to tell you this," he said cheerfully.

"I am not sorry, and yet I am," said Olga thoughtfully. "I know much about Mark Dane, and want to save him from his bad companions. But I hope Steel won't put him in gaol; that would ruin him entirely. Besides, Steel promised not to have him arrested."

"Promised you?" said Ware, astonished.
