He climbed out of the car, went over to the door of the garage, and pushed the emergency button. The door remained obstinately shut. Without stopping to wonder what had happened, he sprinted around to the front door of the house, unlocked it, and pressed the wall switch. The lights didn't come on, and he knew what had happened. Trailing a stream of blue invective, he ran to the rear of the house and went down the basement stairs. Sure enough. Somebody had taken his house Converter, too. And they hadn't even had the courtesy to shunt him back onto the power lines. At his home, he had built more carefully than he had at the lab. He had rigged in a switch which would allow him to use either the Converter or the regular power sources, so that he could work on the Converter if he wanted to. His basement was almost a duplicate of his lab in the city, except that at home he built gadgets just for the fun of watching them work, while at the lab he was doing more serious research. He went over to the cabinet where the switch was, opened it, and punched the relay button. The lights came on. He stalked back up the stairs and headed for the visiphone. First, he dialed his patent attorney's office; he needed some advice. If Power Utilities had their hands on two out of three of his Converters, there might be some trouble over getting the patents through. The attorney's secretary said he wasn't in, and she didn't know if he expected to be back that day. It was, she informed Bending rather archly, nearly five in the afternoon. Bending thanked her and hung up. He dialed the man's home, but he wasn't there, either. Sam Bending stuck a cigarette in his mouth, fired it up, walked over to his easy-chair and sat down to think. According to the police, the first Converter had been stolen on Friday night. The second one had obviously been taken sometime this morning, while he was in the lab with the police. That made sense. The first one they'd tried to open had fused, so they decided to try to get a second one. Only how had they known he had had more than one? He hadn't told anyone that he had three--or even two. Well, no matter. They _had_ found out. The question was, what did he do next? Inform the police of the two thefts or-- There was a car pulling up outside the house. Sam stood up and glanced out the window. It was a steel-blue Ford. By Heaven! Did they intend to steal the third Converter, too? And right in front of his eyes, before it even got decently dark? Sam was so furious that he couldn't even think straight. When the two men climbed out of the car and started walking toward the house, Sam ran back into his study, pulled open his desk drawer, and took out the .38 Special he kept there. It was the work of seconds to thumb six cartridges into the chambers and swing the cylinder shut. The door chime sounded. * * * * *
