“Forgive me. I hate the necessity that imposes restraint. Now, Mrs. Laing, enlighten me on one point, and I shall acquaint you with such few details of Captain Warden’s recent movements as are in my possession. What interest had he in Rabat?”

“I—really—don’t know.”

The protest was honest. This fashionable lady was speaking the truth.

“Who, in your opinion, might know?” he persisted.

Rosamund was not prepared for that. Her mind flew instantly to Evelyn Dane. Of course she would not mention the girl’s name; the mere thought of Evelyn cast a shadow over her mobile face.

“I haven’t the faintest notion,” she said.

The accompanying smile was forced, and the Under Secretary was not in the least deceived.

“Of course, if you cannot tell me why Captain Warden should go ashore at Rabat no one can, I suppose,” and Rosamund caught the pleasing hint of her dominance in all that affected the man she loved.

“You keep on referring to this place that I have never before heard of,” she cried. “Is he still at Rabat? I have ascertained that he is not at Lagos, or in Southern Nigeria, because I cabled for information.”

“When last I heard of Captain Warden he was at Rabat,” said the Under Secretary. “He is not there now. Indeed, I cannot tell you where he is. If the earth had opened and swallowed him, he could not have disappeared more completely.”
