he heavy water.

At Hong Kong, Long Shadow had shown up again.

Bradley, in the meanwhile, had not been idle. Through his various
sources of information he had determined that the source of the heavy
water was in the neighborhood of Korse Lenken. Chahda was instructed to
go there at once and start reconnoitering while they waited for the
party from the States. Bradley deliberately dropped the disguise he had
been using, that of a Portuguese seaman, and let Long Shadow locate him.
Then he had started out, hoping to draw the enemy away from Chahda long
enough for the boy to get clear and start for Korse Lenken. Bradley was
to shake the enemy when he could and resume his investigation. Finding
the source of the water was not enough, he had said. It also was
necessary to find out how it was reaching Singapore, and what its
ultimate destination might be.

Chahda had experience with Buddhist monasteries dating back to the time
when he had worked in Nepal. Also, many Indians were Buddhists. There
were some in almost every monastery, and of that number a few could be
depended on to speak Hindi, or Hindustani as it was called, which was

Nepal.

"I came here easy," Chahda finished. "There was a big lot of pilgrims
and they took me in." He grinned. "They thought I was a monk. And I

from?"

"Tomorrow I show you," Chahda promised.

"Who is Long Shadow?" Rick demanded.

Chahda shrugged. "Not knowing. We never see him. Only the shadow."

Scotty stirred up the fire a little. "How come Canton Charlie didn't
turn you over to the enemy as he did us?"

"What?" Chahda was astonished.

Scotty quickly outlined their adventures while Chahda listened
thoughtfully. When he had finished, the Indian boy shook his head.
"Something bad wrong. Charlie is one of Bradley's men. My boss pays him,
and he is friendly. You say Charlie told you to go to this junk?"

Rick thought back. Charlie himself actually had not told them. They had
not seen Charlie when the note was dropped on their table.

"Charlie himself didn't tell us," he stated. "It could have been one of
Long Shadow's men. Or one of Ko's. And that Portuguese with the knife
could have been one of Lo
