“A Japanese?” he asked.

The Inspector assented.

“I am sorry,” the Prince said, with a touch of added gravity in his manner, “that one of my race should have committed a misdemeanor in this country, but if that is so, your way, of course, is clear. You must arrest him and deal with him as an ordinary English criminal. He is here to live your life, and he must obey your laws.”

“In time, sir,” Inspector Jacks said slowly, “we hope to do so, but over here we may not arrest upon suspicion. We have to collect evidence, and build and build until we can satisfy any reasonable individual that the accused person is guilty.”

The Prince sighed sympathetically.

“It is not for me,” he said, “to criticize your methods.”

“I come now,” Inspector Jacks said slowly, “to the object of my call upon Your Highness. Following upon what I have just told you, certain other information has come into my possession to this effect—that not only was this murderer a Japanese, but we have evidence which seems to suggest that he was attached in some way to your household.”

“To my household!” the Prince repeated.

“To this household, Your Highness,” the detective repeated.

The Prince shook his head slowly.
