"If human aid can prove her innocence, you can depend upon me," was Ware's reply. And taking leave of Mrs. Cairns, he left the Institute with his heart beating and his head in the air.

Giles was glad that his good fortune had led him to meet this true friend of the woman he loved. He was also glad that he had been so open with her about his passion, else she might not have sent him to the Princess Karacsay. As the name came into his mind he glanced down at the paper, which he still held. The address of Anne's friend was "42, Gilbert Mansions, Westminster." Giles resolved to lose no time in looking her up. She would be able to tell him where Anne was, and also might be able to explain the mystery of Anne's life in general, and her conduct at Rickwell in particular.

For there was some mystery about Miss Denham. Ware was quite certain on that point. She had said that her father was dead, and circumstances pointed to the fact that her father was alive and was the nameless man who had appeared and disappeared so suddenly. Then there was the strange episode of the anonymous letter, and the queer reference therein to the Scarlet Cross. Also the fact that the yacht in which Anne had fled was called The Red Cross. All these things hinted at a mystery, and such might in some indirect way be connected with the death of Daisy Kent. Anne had not killed her; but since she had aided the murderer to escape she must have condoned the crime in some way. Ware shuddered as he looked at the matter in this light. What if Anne knew something about the matter after all? The next moment he put the thought from him with anger. Anne was good and pure, and her hands were clean from the stain of blood. Such a woman would not—could not commit a crime either directly or indirectly. When he saw her he would ask for an explanation, and once she opened her mouth all would be made plain.

Arguing thus with himself, Giles wrote a letter to the Princess Karacsay and asked for an interview. He mentioned that he had seen Mrs. Cairns and that the old lady had furnished him with the address. Also, he said that his wish in seeing the Princess was to ask for the whereabouts of Miss Denham. Having despatched this note, Giles felt that he could do no more until he received a reply.

But he was too restless to remain quiet. It occurred to him that he might look up Steel and learn what fresh discoveries had been made in connection with the Rickwell crime. He went to New Scotland Yard and asked for the detective, but learned to his surprise and vexation that the man was out of town and was not expected back for a week. No one could say where he had gone, so Giles had to satisfy himself with leaving a card and promising to call again.

The next day he received a note from the Princess Karacsay asking him to come the next evening at nine o'clock. She said nothing about Anne, nor did she volunteer any information. She simply appointed an hour and a place for the interview and signed herself Olga Karacsay. Giles felt that she had been intentionally curt, and wondered if she intended to give him a civil reception. After some thought he decided that she meant to be kind, although the note read so coldly. He would go, and perhaps during the interview she might be persuaded to help him. After all, she must know that he had been engaged to marry the dead girl, and fancied—as Mrs. Cairns had done—that he wished to have Anne arrested.

The following evening he arrayed himself with particular care and drove in a hansom to Westminster. The cab stopped before a great pile of brick buildings near the Abbey, and when Giles had dismissed it he entered a large and well-lighted hall with a tesselated pavement. Here a porter volunteered, on ascertaining his business, to conduct him to the door of the Princess Karacsay's flat, which was on the first floor.

Giles was admitted by a neat maid-servant, who showed him into a picturesque drawing-room. A tall woman in evening dress was standing beside the window in the twilight. Giles thought her figure was familiar and recognized the turn of her head. He uttered a cry.

"Anne," he said, stretching his arms. "Anne, my dearest!"
