note which
had been thrust under the door. Now he remembered that Jerry the Rat had
spoken of a Jap as a member of the Radicals, and he wondered if
Cio-Cio-San's visitor was the same man. If that were so, then what was
his game? Was he planning to lead Cio-Cio-San into a trap? Certainly if
the treasure the strange Jap had spoken of as having been stolen from
the Japanese girl was the envelope of diamonds, and they had hoped to
recover them from Johnny that night, they would have no intention of
restoring them to Cio-Cio-San.

"I'd advise her, if I were you," said Johnny slowly, "to find out as
much as she can, and not take too many chances. The man may be one of
the Radicals, and he may be using the supposed treasure as a decoy. At
the same time, if she handles the affair discreetly enough, she may be
able to assist you in locating the Russian and his band, which, I take

Dull and heavy, there came the tread of feet on the bridge.

"The police!" whispered Johnny.

Hanada seemed distinctly nervous.

As the two patrolmen came abreast of them one of them flashed his light.

Hanada cringed into the shadows.

"Well," said a deep voice, "here's luck! Youse guys come with us. Youse
guys is wanted at the station."

"What for?" Johnny demanded.

"Youse guys know well enough. Treason, they call it."

"Treason?" Johnny gave a happy laugh. "Treason? They'll have hard work
to prove that."

Had one been privileged to see Cio-Cio-San at the moment Johnny Thompson
and his friend were arrested, he might easily have imagined that she was
back in Japan. The room in which she paced anxiously back and forth was
Japanese to the final detail. The floor was covered thickly with
mattings and the walls, done in a pale blue, were hung everywhere with
long scrolls of ancient Japanese orig
