“And now, Katura,” Dave went on, “I am going to ask you if you can clear up the mystery as to how this medallion, this magnificent heirloom of yours, fell into Mrs. Darrin’s hands.”

“I came to see if you could account for that,” replied the little lieutenant coldly, though his face still wore a smile.

“Why, what do you mean?” asked Dave. “All I know is that, upon my return, I found that Mrs. Darrin had been presented, under very strange circumstances, with this medallion, which I instantly recognized as yours.”

“I saw it in her hand when she opened the door to us,” Katura answered. “Beyond that, about all that I know, Mr. Darrin, is that, upon my arrival at the Okugawa Bank, I found the box missing from the pocket in which I had placed it.”

“Then it was not you who sent this box and its contents to Mrs. Darrin?” the American ensign demanded.

“I did not send it to her,” Katura rejoined.

“Then how did she come to receive it?”

“That is what I have come to ask you, Mr. Darrin,” returned the little infantry lieutenant.

“What do you mean?” asked Dave, coloring slightly, for, despite the smiles on the three Japanese faces, there was something accusing in their manners.

“How did this box happen to reach your wife?” asked Lieutenant Hata, gravely.
