“Well?” she asked.

“I have met Prince Maiyo myself,” Mr. Harvey continued, “and I have found him a charming representative of his race. I am not going to say a word against him. If he were an American, we should be proud of him. If he belonged to any other country, we should accept him at once for what he appears to be. Unfortunately, however, he belongs to a country which we have some reason to mistrust. He belongs to a country in whose national character we have not absolute confidence. For that reason, my dear Penelope, we mistrust Prince Maiyo.”

“I do not know him so well as you seem to imagine,” Penelope said slowly. “We are not even friends, in the ordinary acceptation of the word. I am, to some extent, prejudiced against him. Yet I do not believe that he is capable of a dishonorable action.”

“Nor do I,” the Ambassador declared smoothly. “Yet in every country, almost in every man, the exact standard of dishonor varies. A man will lie for a woman’s sake, and even in the law courts, certainly at his clubs and amongst his friends, it will be accounted to his righteousness. A patriot will lie and intrigue for his country’s sake. Now I believe that to Prince Maiyo Japan stands far above the whole world of womankind. I believe that for her sake he would go to very great lengths indeed.”

“Go on, please,” Penelope murmured.

“The Prince is over here on some sort of an errand which it isn’t our business to understand,” Mr. Harvey said. “I have heard it rumored that it is a special mission entirely concerned with the renewal of the treaty between England and Japan. However that may be, I have sat here, and I have thought, and I have come to this conclusion, ridiculous though it may seem to you at first. I believe that somewhere behind the hand which killed and robbed Hamilton Fynes and poor Dicky stood the benevolent shadow of our friend Prince Maiyo.”

“You have no proof?” she asked breathlessly.

“No proof at all,” the Ambassador admitted. “I am scarcely in a position to search for any. The conclusion I have come to has been simply arrived at through putting a few facts together and considering them in the light of certain events. In the first place, we cannot doubt that the secret of those despatches reached at once the very people whom we should have preferred to remain in ignorance of them. Haven’t I told you of the sudden cessation of the war alarm in Japan, when once she was assured, by means which she could not mistrust, that it was not the intention of the American nation to make war upon her? The subtlety of those murders, and the knowledge by which they were inspired, must have come from some one in an altogether unique position. You may be sure that no one connected with the Japanese Embassy here would be permitted for one single second to take part in any such illegal act. They know better than that, these wily Orientals. They will play the game from Grosvenor Place right enough. But Prince Maiyo is here, and stands apart from any accredited institution, although he has the confidence of his Ambassador and can command the entire devotion of his own secret service. I have not come to this conclusion hastily. I have thought it out, step by step, and in my own mind I am now absolutely convinced that both these murders were inspired by Prince Maiyo.”

“Even if this were so,” Penelope said, “what can I do? Why have you sent for me? The Prince and I are not on especially friendly terms. It is only just lately that we have been decently civil to one another.”

The Ambassador looked at her with some surprise.
