"Very good," I nodded, throwing the last lock on my trap. "That means he knows all about this battleship." "The subject has no knowledge of the battleship," the robot said coldly. "All of his statements concerning the construction of this ship were true." Now it was my turn for the gaping and eye-popping act while Ferraro pulled himself together. He had no idea I wasn't interested in his other hanky-panky, but could tell I had had a low blow. It took an effort, but I managed to get my mind back into gear and consider the evidence. [Illustration] If President Ferraro didn't know about the battleship, he must have been taken in by the cover-up job. But if he wasn't responsible--who was? Some militaristic clique that meant to overthrow him and take power? I didn't know enough about the planet, so I enlisted Ferraro on my side. This was easy--even without the threat of exposure of the documents I had found in his files. Using their disclosure as a prod I could have made him jump through hoops. It wasn't necessary. As soon as I showed him the different blueprints and explained the possibilities he understood. If anything, he was more eager than I was to find out who was using his administration as a cat's-paw. By silent agreement the documents were forgotten. We agreed that the next logical step would be the Cenerentola Spaceyards. He had some idea of sniffing around quietly first, trying to get a line to his political opponents. I gave him to understand that the League, and the League Navy in particular, wanted to stop the construction of the battleship. After that he could play his politics. With this point understood he called his car and squadron of guards and we made a parade to the shipyards. It was a four-hour drive and we made plans on the way down. * * * * * The spaceyard manager was named Rocca, and he was happily asleep when we arrived. But not for long. The parade of uniforms and guns in the middle of the night had him frightened into a state where he could hardly walk. I imagine he was as full of petty larceny as Ferraro. No innocent man could have looked so terror stricken. Taking advantage of the situation, I latched my motorized lie detector onto him and began snapping the questions. Even before I had all the answers I began to get the drift of things. They were a little frightening, too. The manager of the spaceyard that was building the ship had no idea of its true nature.
