They do not have heat sensors, so they stumble around in the dark and trip over things like children. They squander more energy on electric lights than on anything else in the economy. Also, their hearing and eyesight cannot be compared to ours. I am always hearing and seeing things without their suspecting it. A low conversation across the room is perfectly audible to me. Much of my best information comes this way. Naturally, since they completely lack heat generators, they cannot set things on fire. To get back to the account of my activities, Excellency; my biggest mistake was in killing the two women for the femininity research. This got me into terrible trouble. They feel strongly about killing women here. Now that I appreciate their women, I can see why. The local police were not hard to handle, but they have a central police system called the F.B.I. It is comparable to Your Excellency's organization in techniques and training, and in some ways even superior to it. When the F.B.I. started investigating me, things got serious immediately. One day my heat sensor detected a man standing outside my front door. He was a huge bulky man. I sensed a mass under his left arm pit. My heat sensor analyzed it. It reflected heat like iron, but there seemed to be some small pieces of lead there too. The man was polite and apologetic when I opened the door. He tipped his hat. He said that he had come to the wrong apartment. Then he asked, "How did you know I was standing outside the door?" Without thinking, I uttered the first thing that came into my head. "I saw your shadow." His eyes widened only slightly. He had good control of himself. "How could you see a shadow through a wooden door?" he asked softly. I was exasperated at my mistake but I smiled the way people here do when they are at a disadvantage. "I do not explain my tricks," I told him. "I earn my living by performing them at the theatre." I closed the door. The next night I was experimenting with the male principle. I sat on a bench in a place called Central Park and practiced on the women as they went by. I discovered that the more feminine the women the greater the effect the wave has on them. Some would hesitate and look around as they walked by me. Some would stop and stare at me in a puzzled fashion. I was growing tired and ravenously hungry. I decided that when the next attractive woman passed me I would generate one last powerful wave, and then go on to a restaurant. * * * * * I allowed a few unfeminine ones to go by. Then I saw her, a lovely blonde girl about twenty-five years old. Her hair was a mass of short curls that covered her head with a uniform thickness like the styles in our Second Renaissance Period. She had on a black dress and was carrying a black bag in her hand. I sensed small pieces of different types of metals in her bag. She was walking slowly and weeping. Occasionally she dabbed at her nose with a piece of white cloth.
