red. He died happy knowing that he had
served his country well, and I guess that's about all any Jap asks."

"Oh, yes, one more thing," he went on; "he cleared up that little matter
of conspiracy before he died. Something that concerned him alone. You
weren't in it. His part, well, you might call it treason, then again you
mightn't. Considering what he's done for this country and his, we don't
call it treason. It's been sponged off the slate."

"I'm glad to hear that," sighed Johnny, as he turned to rejoin Mazie.

CHAPTER XXI

THE OWNER OF THE DIAMONDS

Johnny did not return to his room that night. After reporting to the
police station and letting them know where he might be found if needed,
he secured a room in one of Chicago's finest hotels, and pulling down
the blinds turned in to sleep until noon.

When he awoke he remembered at once that he had several little matters
to attend to. Hanada's funeral would be cared for by his own people. But
he must see Cio-Cio-San; he must get the hundred dollars promised to

had never dreamed of meeting. Yet here was the man's note requesting him
to meet him in his private office at five o'clock.

"All right, I'll do that little thing," Johnny whispered to himself,
"but meantime I'll go out to the University and see Cio-Cio-San."

An hour later he found himself sitting beside the Japanese girl on the
thick mats of that Japanese room at her club.

"Cio-Cio-San," he said thoughtfully, "I remember hearing you tell of
having been robbed of a treasure. Did you find it last night in the
submarine?"

"No," she said softly. "Last night was a bad night for me. I lost my
best friend. He is dead. I lost my treasure. I do not hope to ever find
it now."

"Cio-Cio-San," Johnny said the name slowly. "Since you do not hope ever
to see your treasure again, perhaps you will tell me what it was."

"Yes, I will tell you. You are my good friend. It was diamonds, one
hundred and ten diamonds and ten rubies, all in
