"Hell, Milly, you aren't working!" someone shouted at her. "Have another!" Milly snapped out of it. She giggled, suppressed a ladylike belch and brightened. "Unless—" he said it loud enough for the employes to scent a great proposal and the room grew quiet—"unless we broke the rules Milly was still deciphering the form. Now she let out a little squeal of excitement. slightly crushed thin cardboard box lay on top. Ann pulled out the dress and shook it into a freely hanging position. Then she groaned. It was green and she had ordered blue. It didn't remotely resemble the dress she had admired from the Hartshorne-Logan catalogue illustration. Moreover, the shoulders were lumpier than any small Sally looked scared until she saw her mother's face. Then she squealed in delight. Ann's legs were rubber. She was shaking her head and wobbling "Les! I'm going crazy or something. Sally just—" Les pulled off the lid and found inside a circular, shiny metal object. Les stared at his wife and put the child onto the rug. Sally began to His jaw dropped. "My God! Ann, what—" Ann was staring, too, but not at her daughter. "Les! The hassock! It used to be brown!" The hassock was a livid shade of green. A neon, demanding, screaming green that clashed horribly with the soft browns and reds in which Ann had furnished the room. "That round thing must be leaking," Les said. "But did you see Sally jumped up, strode to the hassock and picked up the manky with two fingers. She tossed it to Les. Immediately, she regretted her action. "Drop it!" she yelled. "Maybe it'll turn you green, too!" Les kicked the hassock into the hall closet, tossed the manky in after it and shut the door firmly. As the door closed, he saw the entire interior of the dark closet brighten into a wet-lettuce green. When he turned back to Ann, she was staring at her left hand. The wedding band that Les had put there a dozen years ago was a brilliant green, shedding its soft glow over the finger up to the first knuckle. Ann felt the scream building up inside her. She opened her mouth to let it out, then put her hand in front of her mouth to keep it in, finally jerked the hand away to prevent the glowing ring from turning her front teeth green. She collapsed into Les's arms, babbling incomprehensibly. He said: "It's all right. There must be balloons or something in the dye or whatever it is will wash off." Ann immediately felt better. She put her hands behind her back, pulled off her ring and slipped it into her apron pocket. Les was sentimental determinedly off the tinge of green that was showing through the apron pocket and didn't dare look back at her daughter's unsettling means of Ann stared at her son. He stared back at her, the detective outfit under his arm. Les yanked at the doorknob. It didn't yield for him, either. He looked "Where did this come from?" Les held a small object in the palm of his hand, keeping it away from his body. A few drops of something unpleasant were dripping from his fingers. The object looked remarkably like a human eyeball. It was human-size, complete with pupil, iris and rather bloodshot veins. Les laid the eyeball on the table and walked away. The eyeball rolled eyeball rolled nimbly out of the path of the kick. Les didn't hear her. He strode to the detective set, followed at a safe distance by the eyeball, and picked up the box. "Hey, watch out!" Bob cried. A small flashlight fell from the box, landed on its side and its bulb flashed on, throwing a pencil of light across Les's hands. Bob retrieved the flashlight and turned it off while Les glanced through an instruction booklet, frowning. "I'm going to return it, if you don't smudge it up," she replied. "Look at the marks you made on the instructions." The black finger-marks stood out clearly against the shiny, coated paper. Les looked at his hands. "I didn't do it," he said, pressing his clean fingertips against the kitchen table. Black fingerprints, a full set of them, stood out against the sparkling polished table's surface. "I think the Detectolite did it," Bob said. "The instructions say you've got to be very careful with it, because its effects last for a long time." Les began scrubbing his hands vigorously at the sink. Ann watched him silently, until she saw his fingerprints appear on the faucet, the soap and the towel. She began to yell at him for making such a mess, when Sally floated into the kitchen. The girl was wearing a nightgown. She picked up the child, felt the hot forehead, and said: "Les, I think The whole family decided that bed might be a good idea, soon after dinner. When the lights went out, the house seemed to be nearly normal. Les put on a pair of gloves and threw a pillowcase over the eyeball. When daylight entered her room, Sally's nightgown had turned back into the new dress. But the little girl was too sick to get out of bed. She wasn't hungry, her nose was running, and she had a dry cough. Les The only good thing about the morning for Ann was the fact that the manky had quieted down some time in the night. After she got Bob to school, she gingerly opened the closet door. The manky was now glowing a bright pink and seemed slightly larger. Deep violet lettering stood out on its side: " knowing perfectly well that it would need to be retrieved for Les after "My son?" Ann asked incredulously. "Bob?" "Yes. It's a little gadget that looks like a water pistol. Your son insists that he didn't know it would make clothing transparent. He claims it was just accident that he tried it out when he was walking by the gym during calisthenics. We've had to call upon every family began to pull it back, she screamed. The doctor dropped the dress and looked in perplexity at the point where it touched Sally's skin. "It's apparently an allergy to some new kind of material. But I don't He looked helpless as he said to Ann: "I don't know quite what to do. The flesh starts to hemorrhage when I pull at the cloth. She'd bleed to death if I yanked it off. But it's such an extreme allergy that it may kill her, if we leave it in contact with the skin." The manky's rattle suddenly began rhythmically from the lower part of the house. Ann clutched the side of the chair, trying to keep herself "Oh, no," Ann breathed. "Something's happened to Les." "Has there been sickness there?" Les held up his hands, palms toward the doctor. "What's wrong with me? My fingers look all right. But they leave black marks on everything I touch." The doctor looked closely at the fingertips. "Every human has natural oil on the skin. That's how detectives get results with their fingerprint powder. But I've never heard of nigrification, in this gesticulating wildly to nobody in particular. "It's murder!" she screamed. "Murder again! He's been poisoned! He's going to die! It means the electric chair!" unbelievingly for a moment, then advanced on him threateningly. Something in his face restrained her, just as she was about to start Les, cursing softly, hurried past them on the way to answer the claims that her husband is poisoned. Young man, I'm going to put you under arrest." The policeman stepped over the threshold. A blue flash darted from
