I phrased my question carefully, as I had him right where I wanted him now. "You deny any knowledge of the Warlord battleship that is being built from these modified plans."
"These are the plans for an ordinary passenger-freighter, that is all I know."
His words had the simple innocence of a young child's. Was he ever caught. I sat back with a relaxed sigh and lit a cigar.
"Wouldn't you be interested in knowing something about that robot who is holding you," I said. He looked down, as if aware for the first time that the robot had been holding him by the wrist during the interview. "That is no ordinary robot. It has a number of interesting devices built into its fingertips. Thermocouples, galvanometers, things like that. While you talked it registered your skin temperature, blood pressure, amount of perspiration and such. In other words it is an efficient and fast working lie detector. We will now hear all about your lies."
Ferraro pulled away from the robot's hand as if it had been a poisonous snake. I blew a relaxed smoke ring. "Report," I said to the robot. "Has this man told any lies?"
"Many," the robot said. "Exactly seventy-four per cent of all statements he made were fake."
"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.
