hile following up another matter, Bradley
accidentally had discovered that heavy water was being sold.

"He was much excited," Chahda said. "I did not know why. Heavy water? I
asked myself what is heavy water. I knew about ice, which is frozen
water and which is heavy. But who would have much excitement about ice?
The Sahib Bradley hurried to the Consulate of America and he sent a
cable to Washington."

Then the scientist had assigned Chahda to watch a certain house in
Singapore, the place from which the heavy water was being taken to
unknown destinations. Chahda had watched for three days without relief,
and he had seen Worthington Ko. Then, since Bradley had not come for
him, he deserted his post long enough to return to their quarters, a
room in an obscure Chinese hotel in Singapore. There he had found
evidence of a fight and bloodstains on the floor. There was no sign of
Bradley.

It was then, Chahda guessed, that Long Shadow had found him. He saw the
shadow several times while he hunted for Bradley. Then, while searching
for his boss in the Tamil quarter, he had been attacked by Chinese thugs
led by Worthington Ko. They had beaten him into insensibility, hustled
him into a taxi, and were carrying him somewhere into the inland of
Malaya when he regained consciousness. He escaped by going headlong
through a window while the car was traveling and then taking cover in
the jungle alongside the road. Going by a roundabout route, he reached
Singapore again. There he found that their luggage was held by the hotel
and the room had been rented to someone else.

Chahda polished his plate with a biscuit and groaned expressively. "I
say to myself then, Chahda, now is time to think real hard. What to do?"

He knew that the cable Bradley had sent asked for Hartson Brant to be
assigned to the job. And he knew also that from Singapore they were to
head for Hong Kong. He knew nothing about Hong Kong, but he did know
that Bradley was acquainted at a place called the Golden Mouse because
he had heard him mention it to a Chinese the scientist used for
undercover work now and then.

"The Long Shadow came again while I was thinking," Chahda continued. "I
saw it in front of the hotel. So I went quick-fast out the back, and ran
through many places until I was sure he could not find me. I went to
where many Indians live in Singapore, and I found a friend."

The friend, another Indian, had gone to the United States Information
