"The other fishermen think it's a place," Terry added, "so they ganged up on her. Two months back, when she sailed, the entire fishing fleet trailed her. They stuck to her closer than brothers. So she sailed around for a solid week and never put a net overboard. Then she came back to Manila--empty. They were furious. The price of fish had gone sky-high in their absence. They went to sea to make some money regardless. When they got back they found _La Rubia_ had sailed after they left, got back before they returned--and she was just loaded with fish, and the market was back to normal. There was bad feeling. There were fights. Some fishermen landed in the hospital and some in jail." A motor truck rolled by on the street outside the shop of the now moribund Jimenez y Cía. The girl automatically turned her eyes to the source of the noise. Then she looked back at Terry. "And then my erstwhile associate Jimenez had a brainstorm," said Terry ruefully. "He sold the skipper of _La Rubia_ on the idea of short-range radar. I built a set for him. It was good for possibly twenty miles. So _La Rubia_ sailed in the dark of the moon with fifty fishing boats swearing violent oaths that they'd follow her to hell-and-gone. When night fell _La Rubia_ put out her lights, used her radar to locate the other boats who couldn't see her, and sneaked out from their midst. She came back loaded down with fish. There were more fights and more men in the hospital and in jail. Some of _La Rubia's_ men boasted that they'd used radar to dodge their rivals. And that's how the police got interested in me." The girl had listened interestedly. "Why?" "Oh, Jimenez began to take orders for radar from other fishing boat owners. If _La Rubia_ could dodge them by radar, they could trail her by radar even in the dark. So the skipper and crew of _La Rubia_ promised blood-curdling things as Jimenez's fate if he delivered a radar set to anybody else. Then the skippers and crews of other boats made even more blood-curdling threats if he didn't deliver radar to them. So Jimenez ran away, leaving me to hold the bag." The girl nodded. "And therefore," said Terry, "I'm shutting up shop. I'll turn the inventory over to the police and go off somewhere until someone learns where _La Rubia_ gets her fish. When things calm down again, I'll come back and start up business once more--without Jimenez. I'll probably stick to electric-eye doors, burglar alarms, closed-circuit television systems and things like that. Then I might make this underwater broadcasting device, if your father still wants it. I'd better not now." "We heard about your problem," said the girl. "Almost exactly the way you just explained it." Terry stared. Then he said politely, "Oh. You did?" "Yes, I thought--" "Then you knew," said Terry more politely still, "that I was leaving town and couldn't make the gadget you want? You knew it before you came here?"
