"Relax!" she said, urging him into one of the lavish apartments. "This is home. How do you like it?" Matt's tired eyes took in the sea green carpet, the glowing walls, the inviting chairs and sofas--especially the sofas. With a sigh, he stretched himself full length on a rose brocaded lounge and closed his eyes. Lynn regarded him fondly and leaned over to kiss his eyelids. "Now wait just a minute," she said. "I've made coffee and sandwiches. I'll be right back." It was fifteen minutes before she reappeared. She was carrying a tray on which a silver coffee pot steamed, flanked by a plate of sandwiches. She had combed out her yellow hair and slipped into a wicked black negligee that did things to the slender almost girlish figure beneath it. A gentle snore greeted her at the threshold. Lynn stopped, regarding the sleeping Matt with a grim expression. Then very deliberately she set the tray down, seized his heels and dragged him off the couch. He hit the floor with a thump and struggled, still half-asleep, to his feet. "If you're going to sleep, Romeo, you might as well use the bed." "Bed?" said Matt groggily. "Where?" "In there." She pointed toward a low doorway at the left. And Matt went. * * * * * Matt awoke the next morning alone, but a vague smell of perfume lingered, and the pillow next his was crushed. The sound of whistling came through the doorway. He sprang out of bed, to discover that he was clad in a pair of his pajamas, of a pale robin's-egg blue--and raised his eyebrows. He lit a cigarette and prowled about the luxurious chamber, opening doors and drawers. His clothes were hanging in one closet, but the other was full of fluffy feminine apparel. The same condition prevailed in the chests; one holding his own shirts, ties, socks; the other crammed with lacy underthings. He ran his hands through his rumpled hair, blue eyes gleaming with interest. At length he went into the bath and showered and shaved. There was only one thing that troubled him. The water that poured from the shower glowed like a spray of light with the minute phosphorescent organisms! The alien amoebas had even invaded the subterranean pools. "My sleeping beauty!" Lynn greeted him when he entered the breakfast room. Matt eyed her appreciatively. Her cheeks were flushed, and she was wearing a crisp blue smock. The mouth-watering smell of frying ham and eggs invaded his nostrils. "Breakfast ready?" "Yes, my somnolent lord. There also have been six calls for you." She ticked them off on her fingers. "Isaac Trigg; then Captain Bascom. Then Isaac Trigg again. After that Sawyer called; then Isaac Trigg. Finally, Isaac Trigg called to say he was on the way up." He said, "Let's eat." "Aren't you curious?" "Yes. But I'm also hungry. Can't you tell me while we eat?" She sat down. "Sawyer called to let you know that Frazer has analyzed the amoebas." Matt looked at her sharply. "Well, what did he find?"
