Scotty shrugged. "It beats me. I didn't know Chahda was planning to leave Bombay. If it comes to that, I didn't know he knew anything about codes." "Neither did I," Rick agreed. "Remember he said something about a job in his last letter? There was something secret about it he couldn't tell us. Maybe that's why he's in Singapore." "Could be. Anyway, we won't know for sure until we get the cable and decipher it. If we _can_ decipher it, that is." "We'll be able to," Rick said confidently. "He wouldn't send us one we couldn't break." Scotty nodded. "I hope you're right. Well, let's go back and get lazy again." "Not me." Rick started for the stairs. "I'm going to stop loafing and get busy. The lenses for the camera arrived a week ago and I haven't even looked at them." "I'll go with you. I got some questions about these new people maybe you can answer." Upstairs in Rick's bedroom, Scotty sat down in the old leather armchair while Rick opened up the doors that concealed his workbench. On the bench was a camera with an odd-looking searchlight and telescope attached. The searchlight gave off invisible infrared rays instead of ordinary light, and the telescope was equipped with special lenses in order to pick up the infrared. When the camera was loaded with special film, it could take pictures in total darkness, provided the subject was within range of the infrared light rays. The camera had played a major part in solving the mystery of _Smugglers' Reef_. With the evidence collected from Rick's pictures, the police had broken up a ring of gunrunners. But Rick still was not satisfied with the camera. He was always striving to find the simplest way of doing a thing. This time, he was planning to eliminate both the spring-driven dynamo that powered the searchlight, and the infrared telescope. A new-type battery in a small metal case already had been mounted under the camera, far enough to one side so it wouldn't interfere with the tripod mount. The battery would give ten hours of service, and it could be replaced in a moment with a spare carried in the pocket. To take the place of the telescope, Rick had ordered lenses made of the special glass that could "see" infrared. He intended to put the lenses in ordinary sunglasses frames, restore the regular view finder to the camera, and turn the telescope over to Scotty. By using the eyeglasses with special lenses he could see whatever the infrared searchlight was lighting up without the need of looking through the special telescope. Using the glasses and searchlight on the camera together, he could see perfectly in the darkness, and he could take movies, too, if he wanted to. He went to work removing the telescope. "I've checked," Scotty said. "That 'scope will fit the mount on my rifle with no changes."
