"Start at the beginning," Rick demanded. "There's a whole lot we don't know. In fact, if you come right down to it, we don't know anything." "Okay." Chahda took a sip of coffee. "I start at start. In Bombay." Chahda had been visiting with his family in Bombay when Bradley arrived in the Indian city. The two had met by accident. Chahda had gone to the Taj Mahal Hotel to write a letter to the boys, because there was no paper or ink at home. Bradley, who happened to be in the lobby, had noticed the address on the envelope as Chahda handed it to the desk clerk. Once the scientist discovered that Chahda knew the Spindrift group and had been on expeditions with them, the rest followed naturally. Bradley, realizing that the clever little Hindu boy would be of great value in his undercover work, had hired him. Chahda didn't say so, but Rick could understand that such was the case. Chahda's duties had been those of general assistant. He had cared for baggage, run errands, acted as secretary, and on a few occasions had been assigned to follow people in whose destinations Bradley was interested. The two had gone from Bombay to New Delhi and Calcutta, then to Singapore. At Singapore, while 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?"
