"You have come to tell me of some new trouble," she cried.

"No, Miss Dunbar—no, Lady Jocelyn, I have no new trouble to announce to you. I have come to this house in search of—of the gentleman who went away last night. I must find him at any cost. All I want is a little help from you. You may trust to me that he shall be found, and speedily, if he lives."

"If he lives!" cried Laura, with a sudden terror in her face. "Surely you do not imagine—you do not fear that——"

"I imagine nothing, Lady Jocelyn. My duty is very simple, and lies straight before me. I must find the missing man."

"You will find my father," said Laura, with a puzzled expression. "Yes, I am most anxious that he should be found; and if—if you will accept any reward for your efforts, I shall be only too glad to give all you can ask. But how is it that you happen to come here, and to take this interest in my father? You come from the banking-house, I suppose?"

"Yes," the detective answered, after a pause, "yes, Lady Jocelyn, I come from the office in St. Gundolph Lane."

Mr. Carter was silent for some few moments, during which his eyes wandered about the apartment in that professional survey which took in every detail, from the colour of the curtains and the pattern of the carpets, to the tiniest porcelain toy in an antique cabinet on one side of the fireplace. The only thing upon which the detective's glance lingered was the lamp, which Margaret had extinguished.

"I'm going to ask your ladyship a question," said Mr. Carter, presently, looking gravely, and almost compassionately, at the beautiful face before him; "you'll think me impertinent, perhaps, but I hope you'll believe that I'm only a straightforward business man, anxious to do my duty in my own line of life, and to do it with consideration for all parties. You seem very anxious about this missing gentleman; may I ask if you are very fond of him? It's a strange question, I know, my lady—or it seems a strange question—but there's more in the answer than you can guess, and I shall be very grateful to you if you'll answer it candidly."

A faint flush crept over Laura's face, and the tears started suddenly to her eyes. She turned away from the detective, and brushed her handkerchief hastily across those tearful eyes. She walked to the window, and stood there for a minute or so, looking out.

"Why do you ask me this question?" she asked, rather haughtily.
