The alien moved, finally, beginning his preparations. In the center of the cabin an image flickered, swarming flecks of light and shadow that filled out a three-dimensional form, complete and detailed. The alien sat back and studied it through hooded yellow eyes--carefully, oh so carefully, for there must be no mistake, not here, not now. The scouts had come and gone, bringing back the data and specimens of the man-things necessary for a satisfactory disguise. Now the alien stared at the image, regarding the bone structure and muscle contour critically. Then, slowly, he began work with the plastiflesh, modelling the sharp angles of his members into neat curves, skillfully laying folds of skin, molding muscle bulges and jointed fingers, always studying the strange, clumsy image that flickered before him. It was the image of a man. That was what they called themselves. There were many of them, and somewhere among them there was psi-presence, feeble and underdeveloped, but there somewhere. He eyed the image again, and pressed a stud on the control panel, and another image met his eyes, an electronic reflection of himself. He studied it, and carefully superimposed the two, adding contour here and there, yellow eyes seeking out imperfections as he worked. There must be no mistake. Failure would mean disgrace and death, horrible, writhing death by dissociation and burning, neuron by neuron. He knew. He had officiated at executions before; delightful experiences, but not to be trifled with. He stared at the image again and then at himself. * * * * * The skin tone was wrong. The yellow came through too clearly in places, and in this strange culture that color was reported to carry unpleasant connotations. He worked pale, sickly-pink stuff into his soft, wrinkle-free skin, then molded out the cheeks and forehead. Hair would be a problem, of course, but then there would be many small imperfections. He smiled grimly to himself. There were other ways of masking imperfections. At last he was satisfied. There was no way to bring the normal reddish color into the pale green lips; there was no way to satisfactorily prepare the myriad wrinkles and creases that crossed the skin of the man-things, but with a little skillful application of projection techniques it did not matter. The alien struggled into the tight, restricting clothes that lay in a bundle, carefully folded and pressed, at his feet. The hard, board-like shoes cut at his ankles, and the hairy stuff of the red-and-white checked shirt made him writhe in discomfort, but once outside the ship he was glad for the warmth. He stepped out onto the ground, and listened again carefully. Then he made certain arrangements with wires, and threw a switch on a small black case near the air lock, and began marching down the hill away from the ship. He would no longer need the ship. Not now.
