Você pode estar confundindo duas histórias - eu também pensei em "The Rag Thing" como mencionado na resposta de user14111. Mas, a "criatura malévola imaterial" "criando a forma de uma mulher a partir de probabilidades e fins aleatórios" é muito parecida com o fim da história de 1952 ". isfdb.org/cgi-bin/title.cgi?58012"> Um ovo por mês de todo "de" Idris Seabright "(Margaret St. Clair).
A criatura nesta história não começa como um trapo embaixo da cama (ela choca de um ovo), mas começa como imaterial, e cria a forma de uma mulher para atrair um homem à sua morte. .
imaterial
The faint pecking from within the egg grew louder. The dark fissure on the pale blue-green background widened and spread. The halves of the shell fell back suddenly, like the halves of a door. The egg was open. There was nothing inside...
...The mnxx bird imago, left alone within the cabin, flitted about busily.
cria a forma de uma mulher a partir de chances e fins aleatórios para atraí-lo para a morte
In its flittings in the cabin during his absence, it had managed to assemble for itself a passable body. It had used newspapers, grapes, and black wool from the afghan as materials. What it had made was short and squat and excessively female, not at all alluring, but it thought George would like it. It held the nail file from the drawer in its one completed hand...
...Her face was only a blur; there the mnxx bird had not felt it necessary to be specific. But she moved towards George with a heavy sensual swaying; she was what George had always wanted and been ashamed of wanting. She was here. He had no questions. She was his. Desire was making him drunk....
...When it was finished, George lay on the sodden carpet flaccidly. His eyes were gone, and a lot of his vital organs....
...The mnxx bird, on the fine strong wings it had plaited for itself out of George's head hair, floated out into the night.
