"I must apologize for coming so late in the evening, madam; but I only arrived at my office, from Dover, an hour ago; and, as your letters seemed somewhat urgent——"

"It is not a moment too late. I would have seen you at midnight. But—perhaps you have not had time to dine. We have only just left the dining-room. Will you let them get you some dinner there before we begin our business?"

"Your ladyship is too good. I dined on the boat—a saving of time—and am quite at your service."

Lady Perivale told her story, Faunce watching her all the time with those tranquil eyes of his, never very keen, never restless. They were absorbent eyes, that took hold of things and held them tight; and behind the eyes there was a memory that never failed.

He watched and listened. He had heard such stories before—stories of mistaken identity. They were somewhat common in divorce court business, and he very seldom believed them, or found that they would hold water. Nor had he a high opinion of women of fashion—women who lived in rooms like this, where a reckless outlay was the chief characteristic, where choicest flowers bloomed for a day, and delicate satin pillows were tossed about the carpet for dogs to lie upon, and toys of gold and silver, jewelled watches, and valuable miniatures, were crowded upon tables to invite larceny. Yet it seemed to him that Lady Perivale's voice rang true, or else that she was a more accomplished actress than those other women.

"Mr. Harding was right, madam," he said, when he had heard her to the end, and had questioned her closely upon some details. "We must find out who your double is."

"And that will be difficult, I'm afraid."

"It may take time and patience."

"And it will be costly no doubt; but you need not be afraid of spending money. I have no father or brother to take my part; no man-friend who cares enough for me——" She stopped, with something like a sob in her voice. "I have nothing but my money."

"That is not a bad thing to begin the battle with, Lady Perivale," answered Faunce, with his shrewd smile; "but money is not quite such an important factor in my operations as most people think. If things cannot be found out in a fairly cheap manner they cannot be found out at all. When a detective tells you he has to offer large bribes to get information, you may take it from me that he is either a fool or a cheat. Common sense is the thing we have most use for, and a capacity for putting two and two together and making the result equal a hundred."
