Agent Counter-Agent by Nick Carter

everyone in that room."
    A shiver of pleasure passed through me.
    "You will not use a gun to kill our enemies, as you tried to do earlier. But you will kill them. Do you understand?"
    "Yes. I understand."
    "Your face will look different to you when you awake from this trance. We will have made you look like an American spy whose name is Nick Carter."
    "Nick Carter," I repeated.
Nick!
That was what Tanya had called me in the dream. It had been a premonition, like the dream about the Luger.
    "You will enter the building as Nick Carter. A member of our group will give you a carafe containing a hidden device. You will take the carafe into the conference room and place it on the table. You will be able to do this because this Nick Carter, whom we have disposed of, has top security clearance at the conference."
    "I understand," I said.
    "During the next two days you will pose as Nick Carter. I will now begin reading from a file on this agent, and you must remember every single detail so that you will be able to impersonate Carter successfully. Also, you have certain knowledge of this man deep inside you. You may utilize just enough of this knowledge to accomplish your impersonation and no more."
    She read from the papers on her lap. The information wasn't difficult to remember. Somehow it seemed very familiar to me.
    "It was I who impersonated Ilse Hoffman," Tanya concluded. "After we release you, you will report immediately to Carters boss, David Hawk. He will wonder why you have been out of touch for two days, and he will ask about me, whom he knows as Ilse Hoffmann. You will say that you took a trip to a country villa with me for a few days because you wanted to check on me but that you are now convinced that I am above suspicion."
    "Yes," I said. "Above suspicion." The information was indelibly recorded on my brain.
    "You will impersonate Nick Carter as cleverly as you know how, doing whatever is expected of you until noon on the day of the conference. You will then ignore any orders they may give you and go to the palace. You must be in the corridor just outside the conference room at exactly one p.m. At that time our man will approach you. He will be wearing a dark blue suit and red tie, with a white carnation in his lapel. He will hand you this carafe, which is the kind that will be used on the conference table." She took a large, ornate carafe from Dimitrov. "Inside it, under the false bottom, will be this device."
    She carefully removed an electronic gadget. It looked like a fancy transistor radio.
    "The device is operated by remote control. It emits sound in a wide range of frequencies, wider than anything previously devised. At certain frequencies and levels of volume, sound is destructive to central nervous tissue. Very brief exposure results in painful death."
    She replaced the gadget in the carafe. "The device will be tuned to the proper frequency by remote control after the afternoon session has begun. Within minutes it will have killed everyone within hearing range, but it will not affect anyone outside the room. After it has done its job, it will emit a much lower sound, which will still sound very high-pitched to your ears. You will be able to hear that sound outside the conference room, where you will be stationed."
    "I will hear the sound outside the conference room," I repeated.
    "After our man gives you the water carafe, you will go to the guards at the door of the room and tell them that the palace staff has asked you to deliver the carafe so that there will be fresh water for the members of the conference. Since Nick Carter has clearance to enter the conference room, they will allow you to take the carafe inside, where you will place it on the table. You wall leave it there and take the other carafe to the nearest service room in the corridor. You will stay away from the immediate area until you see that everyone has entered the conference room for the afternoon session. Then you will take up your place just
