"My opinion is that during the night, someone established a single frame of the opus we were working on. Once this single frame was established, the person removed from the set one object, after which he wiped the stage clean, returning that to the equipment as power but without the object which accounts for seventy thousand kilowatts of energy." "Mr. Woodart, is there any correlation between this power and the Einstein Formula?" "No. The matter is not made--manufactured. It is converted. The energy represents the power required to carry the matter from a storage place to the stage. It is somewhat like lifting a weight to a certain height. There is no correlation between the foot-pounds of energy expended in such and the mass-energy of the stone. However, in lifting a stone, the energy expended in lift will be returned when the stone is let down--excepting that part which is removed from the total while the stone is held in midair." "Then it might be difficult for you to determine just what was removed from the set?" "It might be," said Woodart, looking hard at Harry Foster. "That is all, Mr. Woodart." To the jury, Jones said: "I think you will find that the testimony just given will prove that duplication is possible. My next witness will show just who was duplicated. I now call Lieutenant Miller to the stand." * * * * * "Lieutenant Miller, when you came to the apartment of Harry Foster, what did you find?" "I found Harry Foster, dead of gunshot wounds." "And what else?" "A revolver." "And?" "The revolver was in a far corner of the room," said Miller. "The dead man could not have used it upon himself for numerous reasons, even though the only fingerprints on the weapon were unmistakably those of Harry Foster. One reason is the distance between the body and the weapon; the wounds produced instant death. Another reason is that the dead man's right hand was in his coat pocket--clenched around a duplicate of the revolver." "You can establish the authenticity of this?" "Both weapons had the same serial number. Both bore the same scars from use. Both weapons produced the same landmarks upon test bullets. Yet at that time only one weapon had been fired; the one tossed in the corner." "Your Honor, I enter as Exhibit A these weapons, duplicates of one another. They are definite proof that duplication of objects did take place." "Evidence accepted." "It will be noted that the serial number on these guns is registered in the name of Harry Foster. I will suggest no indictment at this time for the criminal act of having two weapons with the same serial number but I do suggest that it be remembered." He turned to Miller and said, "That is all." Cranshaw arose to cross-question. "Mr. Miller," he asked, "is there any way of telling which of those guns is the original and which is the duplicate. I assume that they are not _both_ duplicates." "Only the marking on the weapon that was fired after the killing."
