The feel was unmistakable to his extra-human sixth sense. And it was emanating from Cabin Seven! Like a cat he reached the door in one silent bound, pressed the button. The panel slid back noiselessly. Except for a blade of light lancing into the cabin from the lighted passage, only darkness lurked beyond the doorway. The alien unhuman feel was suddenly so strong that it was like a cold draft pouring through the blackened entrance, sending chills rippling up his spine. Ileth's eyes were enormous. Saxon could hear her frightened erratic breathing. Her fear-thoughts beat at his brain. "_What is it? What has he found? What's wrong?_" In spite of himself, Saxon could feel the blood drain out of his cheeks. He wanted suddenly to slam the door and run blindly down the corridor, away from that strange creature lurking in the dark of Cabin Seven. He controlled himself, reached noiselessly inside the door, pressed the switch. Light flooded the cabin. "Why, it's just a girl!" said Ileth, who was peering wide-eyed over Saxon's shoulder. She giggled nervously. Saxon stared at the occupant of the cabin, scarcely crediting his eyes. It was a girl right enough, a flaxen haired girl sleeping easily on her back in the narrow bunk. A thin flexoplas coverlet was thrown across her. One slim bare leg dangled over the edge of the bunk. Her face, Saxon saw, was heart shaped, the closed eyelids delicately blue. At Ileth's giggle, the creature opened her eyes, sat upright with a half-suppressed scream. Ileth backed out of the doorway in embarrassment, but Saxon stood as if turned to stone. The tingling sensation was sending goose flesh racing over his skin. The alien emanations were streaming straight from the girl on the bunk. He recovered himself, thought violently, angrily, "_Who are you?_" The girl stared at him without making a sound. Saxon realized that her eyes were amber as topaz, large and strangely lambent. Then a faint smile twitched the corners of her lips. She made no move to escape, not even to cover her breasts and shoulder. "_You!_" the thought reached Saxon tinged with amusement. "_It would be you who discovered me!_" She touched a tiny instrument strapped to her wrist, which Saxon noticed for the first time. "_Who are you?_" he thought again, then narrowed his eyes with crazed disbelief. He could see the bulkhead through the girl. She gave a low laugh. The flexoplas coverlet, which had lain so lightly over her lap, collapsed slowly. The girl was gone, dissolved. Only her throaty laugh lingered in the still air. Saxon rubbed his eyes. He felt Ileth trembling against him as if she had a chill. Setting his jaw, he stepped up to the bunk, felt the sheets. They were warm and still held the impression of the girl's body. He straightened, realized that the tingling in his scalp had ceased. The alien telepath was gone. But where? "Let's get the hell out of here," Ileth said vehemently.
